Android uses the best of Google AI and our advanced security expertise to tackle mobile scams from every angle. Over the last few years, we’ve launched industry-leading features to detect scams and protect users across phone calls, text messages and messaging app chat notifications.
These efforts are making a real difference in the lives of Android users. According to a recent YouGov survey1 commissioned by Google, Android users were 58% more likely than iOS users to report they had not received any scam texts in the prior week2.
But our work doesn’t stop there. Scammers are continuously evolving, using more sophisticated social engineering tactics to trick users into sharing their phone screen while on the phone to visit malicious websites, reveal sensitive information, send funds or download harmful apps. One popular scam involves criminals impersonating banks or other trusted institutions on the phone to try to manipulate victims into sharing their screen in order to reveal banking information or make a financial transfer.
When you launch a participating financial app while screen sharing and on a phone call with a number that is not saved in your contacts, your Android device3 will automatically warn you about the potential dangers and give you the option to end the call and to stop screen sharing with just one tap. The warning includes a 30-second pause period before you’re able to continue, which helps break the ‘spell’ of the scammer's social engineering, disrupting the false sense of urgency and panic commonly used to manipulate you into a scam.
Bringing in-call scam protections to more users on Android
The UK pilot of Android’s in-call scam protections has already helped thousands of users end calls that could have cost them a significant amount of money. Following this success, and alongside recently launched pilots with financial apps in Brazil and India, we’ve now expanded this protection to most major UK banks.
We’ve also started to pilot this protection with more app types, including peer-to-peer (P2P) payment apps. Today, we’re taking the next step in our expansion by rolling out a pilot of this protection in the United States4 with a number of popular fintechs like Cash App and banks, including JPMorganChase.
We are committed to collaborating across the ecosystem to help keep people safe from scams. We look forward to learning from these pilots and bringing these critical safeguards to even more users in the future.

In his 2020 book, “Future Politics,” British barrister Jamie Susskind wrote that the dominant question of the 20th century was “How much of our collective life should be determined by the state, and what should be left to the market and civil society?” But in the early decades of this century, Susskind suggested that we face a different question: “To what extent should our lives be directed and controlled by powerful digital systems—and on what terms?”
Artificial intelligence (AI) forces us to confront this question. It is a technology that in theory amplifies the power of its users: A manager, marketer, political campaigner, or opinionated internet user can utter a single instruction, and see their message—whatever it is—instantly written, personalized, and propagated via email, text, social, or other channels to thousands of people within their organization, or millions around the world. It also allows us to individualize solicitations for political donations, elaborate a grievance into a well-articulated policy position, or tailor a persuasive argument to an identity group, or even a single person...
Trail of Bits has developed constant-time coding support for LLVM, providing developers with compiler-level guarantees that their cryptographic implementations remain secure against branching-related timing attacks. These changes are being reviewed and will be added in an upcoming release, LLVM 22. This work introduces the __builtin_ct_select family of intrinsics and supporting infrastructure that prevents the Clang compiler, and potentially other compilers built with LLVM, from inadvertently breaking carefully crafted constant-time code. This post will walk you through what we built, how it works, and what it supports. We’ll also discuss some of our future plans for extending this work.
The compiler optimization problem
Modern compilers excel at making code run faster. They eliminate redundant operations, vectorize loops, and cleverly restructure algorithms to squeeze out every bit of performance. But this optimization zeal becomes a liability when dealing with cryptographic code.
Consider this seemingly innocent constant-time lookup from Sprenkels (2019):
This code carefully avoids branching on the secret index. Every iteration executes the same operations regardless of the secret value. However, as compilers are built to make your code go faster, they would see an opportunity to improve this carefully crafted code by optimizing it into a version that includes branching.
The problem is that any data-dependent behavior in the compiled code would create a timing side channel. If the compiler introduces a branch like if (i == secret_idx), the CPU will take different amounts of time depending on whether the branch is taken. Modern CPUs have branch predictors that learn patterns, making correctly predicted branches faster than mispredicted ones. An attacker who can measure these timing differences across many executions can statistically determine which index is being accessed, effectively recovering the secret. Even small timing variations of a few CPU cycles can be exploited with sufficient measurements.
What we built
Our solution provides cryptographic developers with explicit compiler intrinsics that preserve constant-time properties through the entire compilation pipeline. The core addition is the __builtin_ct_select family of intrinsics:
This intrinsic guarantees that the selection operation above will compile to constant-time machine code, regardless of optimization level. When you write this in your C/C++ code, the compiler translates it into a special LLVM intermediate representation intrinsic (llvm.ct.select.*) that carries semantic meaning: “this operation must remain constant-time.”
Unlike regular code that the optimizer freely rearranges and transforms, this intrinsic acts as a barrier. The optimizer recognizes it as a security-critical operation and preserves its constant-time properties through every compilation stage, from source code to assembly.
Real-world impact
In their recent study “Breaking Bad: How Compilers Break Constant-Time Implementations,” Srdjan Čapkun and his graduate students Moritz Schneider and Nicolas Dutly found that compilers break constant-time guarantees in numerous production cryptographic libraries. Their analysis of 19 libraries across five compilers revealed systematic vulnerabilities introduced during compilation.
With our intrinsics, the problematic lookup function becomes this constant-time version:
The use of an intrinsic function prevents the compiler from making any modifications to it, which ensures the selection remains constant time. No optimization pass will transform it into a vulnerable memory access pattern.
Community engagement and adoption
Getting these changes upstream required extensive community engagement. We published our RFC on the LLVM Discourse forum in August 2025.
The RFC received significant feedback from both the compiler and cryptography communities. Open-source maintainers from Rust Crypto, BearSSL, and PuTTY expressed strong interest in adopting these intrinsics to replace their current inline assembly workarounds, while providing valuable feedback on implementation approaches and future primitives. LLVM developers helped ensure the intrinsics work correctly with auto-vectorization and other optimization passes, along with architecture-specific implementation guidance.
Building on existing work
Our approach synthesizes lessons from multiple previous efforts:
Simon and Chisnall __builtin_ct_choose (2018): This work provided the conceptual foundation for compiler intrinsics that preserve constant-time properties, but was never upstreamed.
Jasmin (2017): This work showed the value of compiler-aware constant-time primitives but would have required a new language.
Rust’s #[optimize(never)] experiments: These experiments highlighted the need for fine-grained optimization control.
How it works across architectures
Our implementation ensures __builtin_ct_select compiles to constant-time code on every platform:
x86-64: The intrinsic compiles directly to the cmov (conditional move) instruction, which always executes in constant time regardless of the condition value.
i386: Since i386 lacks cmov, we use a masked arithmetic pattern with bitwise operations to achieve constant-time selection.
ARM and AArch64: For AArch64, the intrinsic is lowered to the CSEL instruction, which provides constant-time execution. For ARM, since ARMv7 doesn’t have a constant-time instruction like AAarch64, the implementation generates a masked arithmetic pattern using bitwise operations instead.
Other architectures: A generic fallback implementation uses bitwise arithmetic to ensure constant-time execution, even on platforms we haven’t natively added support for.
Each architecture needs different instructions to achieve constant-time behavior. Our implementation handles these differences transparently, so developers can write portable constant-time code without worrying about platform-specific details.
Benchmarking results
Our partners at ETH Zürich are conducting comprehensive benchmarking using their test suite from the “Breaking Bad” study. Initial results show the following:
Minimal performance overhead for most cryptographic operations
100% preservation of constant-time properties across all tested optimization levels
Successful integration with major cryptographic libraries including HACL*, Fiat-Crypto, and BoringSSL
What’s next
While __builtin_ct_select addresses the most critical need, our RFC outlines a roadmap for additional intrinsics:
Constant-time operations
We have future plans for extending the constant-time implementation, specifically for targeting arithmetic or string operations and evaluating expressions to be constant time.
_builtin_ct<op>// for constant-time arithmetic or string operation
__builtin_ct_expr(expression)// Force entire expression to evaluate without branches
Adoption path for other languages
The modular nature of our LLVM implementation means any language targeting LLVM can leverage this work:
Rust: The Rust compiler team is exploring how to expose these intrinsics through its core::intrinsics module, potentially providing safe wrappers in the standard library.
Swift: Apple’s security team has expressed interest in adopting these primitives for its cryptographic frameworks.
WebAssembly: These intrinsics would be particularly useful for browser-based cryptography, where timing attacks remain a concern despite sandboxing.

Technology should bring people closer together, not create walls. Being able to communicate and connect with friends and family should be easy regardless of the phone they use. That’s why Android has been building experiences that help you stay connected across platforms.
As part of our efforts to continue to make cross-platform communication more seamless for users, we've made Quick Share interoperable with AirDrop, allowing for two-way file sharing between Android and iOS devices, starting with the Pixel 10 Family. This new feature makes it possible to quickly share your photos, videos, and files with people you choose to communicate with, without worrying about the kind of phone they use.
Most importantly, when you share personal files and content, you need to trust that it stays secure. You can share across devices with confidence knowing we built this feature with security at its core, protecting your data with strong safeguards that have been tested by independent security experts.
Secure by Design
We built Quick Share’s interoperability support for AirDrop with the same rigorous security standards that we apply to all Google products. Our approach to security is proactive and deeply integrated into every stage of the development process. This includes:
Threat Modeling: We identify and address potential security risks before they can become a problem.
Internal Security Design and Privacy Reviews: Our dedicated security and privacy teams thoroughly review the design to ensure it meets our high standards.
Internal Penetration Testing: We conduct extensive in-house testing to identify and fix vulnerabilities.
This Secure by Design philosophy ensures that all of our products are not just functional but also fundamentally secure.
This feature is also protected by a multi-layered security approach to ensure a safe sharing experience from end-to-end, regardless of what platform you’re on.
Secure Sharing Channel: The communication channel itself is hardened by our use of Rust to develop this feature. This memory-safe language is the industry benchmark for building secure systems and provides confidence that the connection is protected against buffer overflow attacks and other common vulnerabilities.
Built-in Platform Protections: This feature is strengthened by the robust built-in security of both Android and iOS. On Android, security is built in at every layer. Our deep investment in Rust at the OS level hardens the foundation, while proactive defenses like Google Play Protect work to keep your device safe. This is complemented by the security architecture of iOS that provides its own strong safeguards that mitigate malicious files and exploitation. These overlapping protections on both platforms work in concert with the secure connection to provide comprehensive safety for your data when you share or receive.
You’re in Control: Sharing across platforms works just like you're used to: a file requires your approval before being received, so you're in control of what you accept.
The Power of Rust: A Foundation of Secure Communication
A key element of our security strategy for the interoperability layer between Quick Share and AirDrop is the use of the memory-safe Rust programming language. Recognized by security agencies around the world, including the NSA and CISA, Rust is widely considered the industry benchmark for building secure systems because it eliminates entire classes of memory-safety vulnerabilities by design.
Rust is already a cornerstone of our broader initiative to eliminate memory safety bugs across Android. Its selection for this feature was deliberate, driven by the unique security challenges of cross-platform communication that demanded the most robust protections for memory safety.
The core of this feature involves receiving and parsing data sent over a wireless protocol from another device. Historically, when using a memory-unsafe language, bugs in data parsing logic are one of the most common sources of high-severity security vulnerabilities. A malformed data packet sent to a parser written in a memory-unsafe language can lead to buffer overflows and other memory corruption bugs, creating an opportunity for code execution.
This is precisely where Rust provides a robust defense. Its compiler enforces strict ownership and borrowing rules at compile time, which guarantees memory safety. Rust removes entire classes of memory-related bugs. This means our implementation is inherently resilient against attackers attempting to use maliciously crafted data packets to exploit memory errors.
Secure Sharing Using AirDrop's "Everyone" Mode
To ensure a seamless experience for both Android and iOS users, Quick Share currently works with AirDrop's "Everyone for 10 minutes" mode. This feature does not use a workaround; the connection is direct and peer-to-peer, meaning your data is never routed through a server, shared content is never logged, and no extra data is shared. As with "Everyone for 10 minutes" mode on any device when you’re sharing between non-contacts, you can ensure you're sharing with the right person by confirming their device name on your screen with them in person.
This implementation using "Everyone for 10 minutes” mode is just the first step in seamless cross-platform sharing, and we welcome the opportunity to work with Apple to enable “Contacts Only” mode in the future.
Tested by Independent Security Experts
After conducting our own secure product development, internal threat modeling, privacy reviews, and red team penetration tests, we engaged with NetSPI, a leading third-party penetration testing firm, to further validate the security of this feature and conduct an independent security assessment. The assessment found the interoperability between Quick Share and AirDrop is secure, is “notably stronger” than other industry implementations and does not leak any information.
Based on these internal and external assessments, we believe our implementation provides a strong security foundation for cross-platform file sharing for both Android and iOS users. We will continue to evaluate and enhance the implementation’s security in collaboration with additional third-party partners.
To complement this deep technical audit, we also sought expert third-party perspective on our approach from Dan Boneh, a renowned security expert and professor at Stanford University:
“Google’s work on this feature, including the use of memory safe Rust for the core communications layer, is a strong example of how to build secure interoperability, ensuring that cross-platform information sharing remains safe. I applaud the effort to open more secure information sharing between platforms and encourage Google and Apple to work together more on this."
The Future of File-Sharing Should Be Interoperable
This is just the first step as we work to improve the experience and expand it to more devices. We look forward to continuing to work with industry partners to make connecting and communicating across platforms a secure, seamless experience for all users.
Cybersecurity researchers have warned of an actively expanding botnet dubbed Tsundere that’s targeting Windows users.

Kendra Albert gave an excellent talk at USENIX Security this year, pointing out that the legal agreements surrounding vulnerability disclosure muzzle researchers while allowing companies to not fix the vulnerabilities—exactly the opposite of what the responsible disclosure movement of the early 2000s was supposed to prevent. This is the talk.
Thirty years ago, a debate raged over whether vulnerability disclosure was good for computer security. On one side, full disclosure advocates argued that software bugs weren’t getting fixed and wouldn’t get fixed if companies that made insecure software wasn’t called out publicly. On the other side, companies argued that full disclosure led to exploitation of unpatched vulnerabilities, especially if they were hard to fix. After blog posts, public debates, and countless mailing list flame wars, there emerged a compromise solution: coordinated vulnerability disclosure, where vulnerabilities were disclosed after a period of confidentiality where vendors can attempt to fix things. Although full disclosure fell out of fashion, disclosure won and security through obscurity lost. We’ve lived happily ever after since...

Trail of Bits is publicly disclosing two vulnerabilities in elliptic, a widely used JavaScript library for elliptic curve cryptography that is downloaded over 10 million times weekly and is used by close to 3,000 projects. These vulnerabilities, caused by missing modular reductions and a missing length check, could allow attackers to forge signatures or prevent valid signatures from being verified, respectively.
One vulnerability is still not fixed after a 90-day disclosure window that ended in October 2024. It remains unaddressed as of this publication.
I discovered these vulnerabilities using Wycheproof, a collection of test vectors designed to test various cryptographic algorithms against known vulnerabilities. If you’d like to learn more about how to use Wycheproof, check out this guide I published.
In this blog post, I’ll describe how I used Wycheproof to test the elliptic library, how the vulnerabilities I discovered work, and how they can enable signature forgery or prevent signature verification.
I wrote a Wycheproof testing harness for the elliptic package, as described in the guide. I then analyzed the source code covered by the various failing test cases provided by Wycheproof to classify them as false positives or real findings. With an understanding of why these test cases were failing, I then wrote proof-of-concept code for each bug. After confirming they were real findings, I began the coordinated disclosure process.
Findings
In total, I identified five vulnerabilities, resulting in five CVEs. Three of the vulnerabilities were minor parsing issues. I disclosed those issues in a public pull request against the repository and subsequently requested CVE IDs to keep track of them.
Two of the issues were more severe. I disclosed them privately using the GitHub advisory feature. Here are some details on these vulnerabilities.
CVE-2024-48949: EdDSA signature malleability
This issue stems from a missing out-of-bounds check, which is specified in the NIST FIPS 186-5 in section 7.8.2, “HashEdDSA Signature Verification”:
Decode the first half of the signature as a point R and the second half of the signature as an integer s. Verify that the integer s is in the range of 0 ≤ s < n.
In the elliptic library, the check that s is in the range of 0 ≤ s < n, to verify that it is not outside the order n of the generator point, is never performed. This vulnerability allows attackers to forge new valid signatures, sig', though only for a known signature and message pair, (msg, sig).
$$
\begin{aligned}
\text{Signature} &= (msg, sig) \\
sig &= (R||s) \\
s' \bmod n &== s
\end{aligned}
$$
The following check needs to be implemented to prevent this forgery attack.
if(sig.S().gte(sig.eddsa.curve.n)){returnfalse;}
Forged signatures could break the consensus of protocols. Some protocols would correctly reject forged signature message pairs as invalid, while users of the elliptic library would accept them.
CVE-2024-48948: ECDSA signature verification error on hashes with leading zeros
The second issue involves the ECDSA implementation: valid signatures can fail the validation check.
These are the Wycheproof test cases that failed:
[testvectors_v1/ecdsa_secp192r1_sha256_test.json][tc296] special case hash
[testvectors_v1/ecdsa_secp224r1_sha256_test.json][tc296] special case hash
Both test cases failed due to a specifically crafted hash containing four leading zero bytes, resulting from hashing the hex string 343236343739373234 using SHA-256:
We’ll use the secp192r1 curve test case to illustrate why the signature verification fails.
The function responsible for verifying signatures for elliptic curves is located in lib/elliptic/ec/index.js:
The message must be hashed before it is parsed to the verify function call, which occurs outside the elliptic library. According to FIPS 186-5, section 6.4.2, “ECDSA Signature Verification Algorithm,” the hash of the message must be adjusted based on the order n of the base point of the elliptic curve:
If log2(n) ≥ hashlen, set E = H. Otherwise, set E equal to the leftmost log2(n) bits of H.
To achieve this, the _truncateToN function is called, which performs the necessary adjustment. Before this function is called, the hashed message, msg, is converted from a hex string or array into a number object using newBN(msg, 16).
The delta variable calculates the difference between the size of the hash and the order n of the current generator for the curve. If msg occupies more bits than n, it is shifted by the difference. For this specific test case, we use secp192r1, which uses 192 bits, and SHA-256, which uses 256 bits. The hash should be shifted by 64 bits to the right to retain the leftmost 192 bits.
The issue in the elliptic library arises because the new BN(msg, 16) conversion removes leading zeros, resulting in a smaller hash that takes up fewer bytes.
This miscalculation results in an incorrect delta of 32 = (288 - 192) instead of 64 = (328 - 192). Consequently, the hashed message is not shifted correctly, causing verification to fail. This issue causes valid signatures to be rejected if the message hash contains enough leading zeros, with a probability of 2-32.
To fix this issue, an additional argument should be added to the verification function to allow the hash size to be parsed:
These vulnerabilities serve as an example of why continuous testing is crucial for ensuring the security and correctness of widely used cryptographic tools. In particular, Wycheproof and other actively maintained sets of cryptographic test vectors are excellent tools for ensuring high-quality cryptography libraries. We recommend including these test vectors (and any other relevant ones) in your CI/CD pipeline so that they are rerun whenever a code change is made. This will ensure that your library is resilient against these specific cryptographic issues both now and in the future.

We’re releasing Slither-MCP, a new tool that augments LLMs with Slither’s unmatched static analysis engine. Slither-MCP benefits virtually every use case for LLMs by exposing Slither’s static analysis API via tools, allowing LLMs to find critical code faster, navigate codebases more efficiently, and ultimately improve smart contract authoring and auditing performance.
How Slither-MCP works
Slither-MCP is an MCP server that wraps Slither’s static analysis functionality, making it accessible through the Model Context Protocol. It can analyze Solidity projects (Foundry, Hardhat, etc.) and generate comprehensive metadata about contracts, functions, inheritance hierarchies, and more.
When an LLM uses Slither-MCP, it no longer has to rely on rudimentary tools like grep and read_file to identify where certain functions are implemented, who a function’s callers are, and other complex, error-prone tasks.
Because LLMs are probabilistic systems, in most cases they are only probabilistically correct. Slither-MCP helps set a ground truth for LLM-based analysis using traditional static analysis: it reduces token use and increases the probability a prompt is answered correctly.
Example: Simplifying an auditing task
Consider a project that contains two ERC20 contracts: one used in the production deployment, and one used in tests. An LLM is tasked with auditing a contract’s use of ERC20.transfer(), and needs to locate the source code of the function.
Without Slither-MCP, the LLM has two options:
Try to resolve the import path of the ERC20 contract, then try to call read_file to view the source of ERC20.transfer(). This option usually requires multiple calls to read_file, especially if the call to ERC20.transfer() is through a child contract that is inherited from ERC20. Regardless, this option will be error-prone and tool call intensive.
Try to use the grep tool to locate the implementation of ERC20.transfer(). Depending on how the grep tool call is structured, it may return the wrong ERC20 contract.
Both options are non-ideal, error-prone, and not likely to be correct with a high interval of confidence.
Using Slither-MCP, the LLM simply calls get_function_source to locate the source code of the function.
Simple setup
Slither-MCP is easy to set up, and can be added to Claude Code using the following command:
For now, Slither-MCP exposes a subset of Slither’s analysis engine that we believe LLMs would have the most benefit consuming. This includes the following functionalities:
Extracting the source code of a given contract or function for analysis
Identifying the callers and callees of a function
Identifying the contract’s derived and inherited members
Locating potential implementations of a function based on signature (e.g., finding concrete definitions for IOracle.price(...))
Running Slither’s exhaustive suite of detectors and filtering the results
Slither-MCP is licensed AGPLv3, the same license Slither uses. This license requires publishing the full source code of your application if you use it in a web service or SaaS product. For many tools, this isn’t an acceptable compromise.
To help remediate this, we are now offering dual licensing for both Slither and Slither-MCP. By offering dual licensing, Slither and Slither-MCP can be used to power LLM-based security web apps without publishing your entire source code, and without having to spend years reproducing its feature set.
If you are currently using Slither in your commercial web application, or are interested in using it, please reach out.
Short-finned pilot wales (Globicephala macrorhynchus) eat at lot of squid:
To figure out a short-finned pilot whale’s caloric intake, Gough says, the team had to combine data from a variety of sources, including movement data from short-lasting tags, daily feeding rates from satellite tags, body measurements collected via aerial drones, and sifting through the stomachs of unfortunate whales that ended up stranded on land.
Once the team pulled all this data together, they estimated that a typical whale will eat between 82 and 202 squid a day. To meet their energy needs, a whale will have to consume an average of 140 squid a day. Annually, that’s about 74,000 squid per whale. For all the whales in the area, that amounts to about 88,000 tons of squid eaten every year...

As AI capabilities grow, we must delineate the roles that should remain exclusively human. The line seems to be between fact-based decisions and judgment-based decisions.
For example, in a medical context, if an AI was demonstrably better at reading a test result and diagnosing cancer than a human, you would take the AI in a second. You want the more accurate tool. But justice is harder because justice is inherently a human quality in a way that “Is this tumor cancerous?” is not. That’s a fact-based question. “What’s the right thing to do here?” is a human-based question...
The Trail of Bits cryptography team is releasing our open-source pure Go implementations of ML-DSA (FIPS-204) and SLH-DSA (FIPS-205), two NIST-standardized post-quantum signature algorithms. These implementations have been engineered and reviewed by several of our cryptographers, so if you or your organization is looking to transition to post-quantum support for digital signatures, try them out!
This post will detail some of the work we did to ensure the implementations are constant time. These tricks specifically apply to the ML-DSA (FIPS-204) algorithm, protecting from attacks like KyberSlash, but they also apply to any cryptographic algorithm that requires branching or division.
The road to constant-time FIPS-204
SLH-DSA (FIPS-205) is relatively easy to implement without introducing side channels, as it’s based on pseudorandom functions built from hash functions, but the ML-DSA (FIPS-204) specification includes several integer divisions, which require more careful consideration.
Division was the root cause of a timing attack called KyberSlash that impacted early implementations of Kyber, which later became ML-KEM (FIPS-203). We wanted to avoid this risk entirely in our implementation.
Each of the ML-DSA parameter sets (ML-DSA-44, ML-DSA-65, and ML-DSA-87) include several other parameters that affect the behavior of the algorithm. One of those is called $γ_2$, the low-order rounding range.
$γ_2$ is always an integer, but its value depends on the parameter set. For ML-DSA-44, $γ_2$ is equal to 95232. For ML-DSA-65 and ML-DSA-87, $γ_2$ is equal to 261888.
ML-DSA specifies an algorithm called Decompose, which converts a field element into two components ($r_1$, $r_0$) such that $(r_1 \cdot 2γ_2) + r_0$ equals the original field element. This requires dividing by $2γ_2$ in one step and calculating the remainder of $2γ_2$ in another.
If you ask an AI to implement the Decompose algorithm for you, you will get something like this:
// This code sample was generated by Claude AI.// Not secure -- DO NOT USE.//// Here, `alpha` is equal to `2 * γ2`, and `r` is the field element:funcDecomposeUnsafe(r,alphaint32)(r1,r0int32){// Ensure r is in range [0, q-1]r=r%qifr<0{r+=q}// Center r around 0 (map to range [-(q-1)/2, (q-1)/2])ifr>(q-1)/2{r=r-q}// Compute r1 = round(r/alpha) where round is rounding to nearest// with ties broken towards zeroifr>=0{r1=(r+alpha/2)/alpha}else{r1=(r-alpha/2+1)/alpha}// Compute r0 = r - r1*alphar0=r-r1*alpha// Adjust r1 if r0 is too largeifr0>alpha/2{r1++r0-=alpha}elseifr0<-alpha/2{r1--r0+=alpha}returnr1,r0}
However, this violates cryptography engineering best practices:
This code flagrantly uses division and modulo operators.
It contains several branches based on values derived from the field element.
Zen and the art of branchless cryptography
The straightforward approach to preventing branches in any cryptography algorithm is to always perform both sides of the condition (true and false) and then use a constant-time conditional swap based on the condition to obtain the correct result. This involves bit masking, two’s complement, and exclusive OR (XOR).
Removing the branches from this function looks something like this:
// This is another AI-generated code sample.// Not secure -- DO NOT USE.funcDecomposeUnsafeBranchless(r,alphaint32)(r1,r0int32){// Ensure r is in range [0, q-1]r=r%qr+=q&(r>>31)// Add q if r < 0 (using arithmetic right shift)// Center r around 0 (map to range [-(q-1)/2, (q-1)/2])mask:=-((r-(q-1)/2-1)>>31)// mask = -1 if r > (q-1)/2, else 0r-=q&mask// Compute r1 = round(r/alpha) with ties broken towards zero// For r >= 0: r1 = (r + alpha/2) / alpha// For r < 0: r1 = (r - alpha/2 + 1) / alphasignMask:=r>>31// signMask = -1 if r < 0, else 0offset:=(alpha/2)+(signMask&(-alpha/2+1))// alpha/2 if r >= 0, else -alpha/2 + 1r1=(r+offset)/alpha// Compute r0 = r - r1*alphar0=r-r1*alpha// Adjust r1 if r0 is too large (branch-free)// If r0 > alpha/2: r1++, r0 -= alpha// If r0 < -alpha/2: r1--, r0 += alpha// Check if r0 > alpha/2adjustUp:=-((r0-alpha/2-1)>>31)// -1 if r0 > alpha/2, else 0r1+=adjustUp&1r0-=adjustUp&alpha// Check if r0 < -alpha/2adjustDown:=-((-r0-alpha/2-1)>>31)// -1 if r0 < -alpha/2, else 0r1-=adjustDown&1r0+=adjustDown&alphareturnr1,r0}
That solves our conditional branching problem; however, we aren’t done yet. There are still the troublesome division operators.
Undivided by time: Division-free algorithms
The previous trick of constant-time conditional swaps can be leveraged to implement integer division in constant time as well.
funcDivConstTime32(nuint32,duint32)(uint32,uint32){quotient:=uint32(0)R:=uint32(0)// We are dealing with 32-bit integers, so we iterate 32 timesb:=uint32(32)i:=bforrangeb{i--R<<=1// R(0) := N(i)R|=((n>>i)&1)// swap from Sub32() will look like this:// if remainder > d, swap == 0// if remainder == d, swap == 0// if remainder < d, swap == 1Rprime,swap:=bits.Sub32(R,d,0)// invert logic of sub32 for conditional swapswap^=1/*
Desired:
if R > D then swap = 1
if R == D then swap = 1
if R < D then swap = 0
*/// Qprime := Q// Qprime(i) := 1Qprime:=quotientQprime|=(1<<i)// Conditional swap:mask:=uint32(-swap)R^=((Rprime^R)&mask)quotient^=((Qprime^quotient)&mask)}returnquotient,R}
This works as expected, but it’s slow, since it requires a full loop iteration to calculate each bit of the quotient and remainder. We can do better.
One neat optimization trick: Barrett reduction
Since the value $γ_2$ is fixed for a given parameter set, and the division and modulo operators are performed against $2γ_2$, we can use Barrett reduction with precomputed values instead of division.
Barrett reduction involves multiplying by a reciprocal (in our case, $2^{64}/2γ_2$) and then performing up to two corrective subtractions to obtain a remainder. The quotient is produced as a byproduct of this calculation.
// Calculates (n/d, n%d) given (n, d)funcDivBarrett(numerator,denominatoruint32)(uint32,uint32){// Since d is always 2 * gamma2, we can precompute (2^64 / d) and use itvarreciprocaluint64switchdenominator{case190464:// 2 * 95232reciprocal=96851604889688case523776:// 2 * 261888reciprocal=35184372088832default:// Fallback to slow divisionreturnDivConstTime32(numerator,denominator)}// Barrett reductionhi,_:=bits.Mul64(uint64(numerator),reciprocal)quo:=uint32(hi)r:=numerator-quo*denominator// Two correction steps using bits.Sub32 (constant-time)fori:=0;i<2;i++{newR,borrow:=bits.Sub32(r,denominator,0)correction:=borrow^1// 1 if r >= d, 0 if r < dmask:=uint32(-correction)quo+=mask&1r^=mask&(newR^r)// Conditional swap using XOR}returnquo,r}
The availability of post-quantum signature algorithms in Go is a step toward a future where internet communications remain secure, even if a cryptography-relevant quantum computer is ever developed.

Last year, we wrote about why a memory safety strategy that focuses on vulnerability prevention in new code quickly yields durable and compounding gains. This year we look at how this approach isn’t just fixing things, but helping us move faster.
The 2025 data continues to validate the approach, with memory safety vulnerabilities falling below 20% of total vulnerabilities for the first time.
<em>Updated data for 2025. This data covers first-party and third-party (open source) code changes to the Android platform across C, C++, Java, Kotlin, and Rust. This post is published a couple of months before the end of 2025, but Android’s industry-standard 90-day patch window means that these results are very likely close to final. We can and will accelerate patching when necessary.</em>
We adopted Rust for its security and are seeing a 1000x reduction in memory safety vulnerability density compared to Android’s C and C++ code. But the biggest surprise was Rust's impact on software delivery. With Rust changes having a 4x lower rollback rate and spending 25% less time in code review, the safer path is now also the faster one.
In this post, we dig into the data behind this shift and also cover:
How we’re expanding our reach: We're pushing to make secure code the default across our entire software stack. We have updates on Rust adoption in first-party apps, the Linux kernel, and firmware.
Our first rust memory safety vulnerability...almost: We'll analyze a near-miss memory safety bug in unsafe Rust: how it happened, how it was mitigated, and steps we're taking to prevent recurrence. It’s also a good chance to answer the question “if Rust can have memory safety issues, why bother at all?”
Building Better Software, Faster
Developing an operating system requires the low-level control and predictability of systems programming languages like C, C++, and Rust. While Java and Kotlin are important for Android platform development, their role is complementary to the systems languages rather than interchangeable. We introduced Rust into Android as a direct alternative to C and C++, offering a similar level of control but without many of their risks. We focus this analysis on new and actively developed code because our data shows this to be an effective approach.
When we look at development in systems languages (excluding Java and Kotlin), two trends emerge: a steep rise in Rust usage and a slower but steady decline in new C++.
Net lines of code added: Rust vs. C++, first-party Android code. This chart focuses on first-party (Google-developed) code (unlike the previous chart that included all first-party and third-party code in Android.) We only include systems languages, C/C++ (which is primarily C++), and Rust.
The chart shows that the volume of new Rust code now rivals that of C++, enabling reliable comparisons of software development process metrics. To measure this, we use the DORA1 framework, a decade-long research program that has become the industry standard for evaluating software engineering team performance. DORA metrics focus on:
Throughput: the velocity of delivering software changes.
Stability: the quality of those changes.
Cross-language comparisons can be challenging. We use several techniques to ensure the comparisons are reliable.
Similar sized changes: Rust and C++ have similar functionality density, though Rust is slightly denser. This difference favors C++, but the comparison is still valid. We use Gerrit’s change size definitions.
Similar developer pools: We only consider first-party changes from Android platform developers. Most are software engineers at Google, and there is considerable overlap between pools with many contributing in both.
Track trends over time: As Rust adoption increases, are metrics changing steadily, accelerating the pace, or reverting to the mean?
Throughput
Code review is a time-consuming and high-latency part of the development process. Reworking code is a primary source of these costly delays. Data shows that Rust code requires fewer revisions. This trend has been consistent since 2023. Rust changes of a similar size need about 20% fewer revisions than their C++ counterparts.
In addition, Rust changes currently spend about 25% less time in code review compared to C++. We speculate that the significant change in favor of Rust between 2023 and 2024 is due to increased Rust expertise on the Android team.
While less rework and faster code reviews offer modest productivity gains, the most significant improvements are in the stability and quality of the changes.
Stability
Stable and high-quality changes differentiate Rust. DORA uses rollback rate for evaluating change stability. Rust's rollback rate is very low and continues to decrease, even as its adoption in Android surpasses C++.
For medium and large changes, the rollback rate of Rust changes in Android is ~4x lower than C++. This low rollback rate doesn't just indicate stability; it actively improves overall development throughput. Rollbacks are highly disruptive to productivity, introducing organizational friction and mobilizing resources far beyond the developer who submitted the faulty change. Rollbacks necessitate rework and more code reviews, can also lead to build respins, postmortems, and blockage of other teams. Resulting postmortems often introduce new safeguards that add even more development overhead.
In a self-reported survey from 2022, Google software engineers reported that Rust is both easier to review and more likely to be correct. The hard data on rollback rates and review times validates those impressions.
Putting it all together
Historically, security improvements often came at a cost. More security meant more process, slower performance, or delayed features, forcing trade-offs between security and other product goals. The shift to Rust is different: we are significantly improving security and key development efficiency and product stability metrics.
Expanding Our Reach
With Rust support now mature for building Android system services and libraries, we are focused on bringing its security and productivity advantages elsewhere.
Firmware: The combination of high privilege, performance constraints, and limited applicability of many security measures makes firmware both high-risk, and challenging to secure. Moving firmware to Rust can yield a major improvement in security. We have been deploying Rust in firmware for years now, and even released tutorials, training, and code for the wider community. We’re particularly excited about our collaboration with Arm on Rusted Firmware-A.
First-party applications: Rust is ensuring memory safety from the ground up in several security-critical Google applications, such as:
Nearby Presence: The protocol for securely and privately discovering local devices over Bluetooth is implemented in Rust and is currently running in Google Play Services.
MLS: The protocol for secure RCS messaging is implemented in Rust and will be included in the Google Messages app in a future release.
Chromium: Parsers for PNG, JSON, and web fonts have been replaced with memory-safe implementations in Rust, making it easier for Chromium engineers to deal with data from the web while following the Rule of 2.
These examples highlight Rust's role in reducing security risks, but memory-safe languages are only one part of a comprehensive memory safety strategy. We continue to employ a defense-in-depth approach, the value of which was clearly demonstrated in a recent near-miss.
Our First Rust Memory Safety Vulnerability...Almost
We recently avoided shipping our very first Rust-based memory safety vulnerability: a linear buffer overflow in CrabbyAVIF. It was a near-miss. To ensure the patch received high priority and was tracked through release channels, we assigned it the identifier CVE-2025-48530. While it’s great that the vulnerability never made it into a public release, the near-miss offers valuable lessons. The following sections highlight key takeaways from our postmortem.
Scudo Hardened Allocator for the Win
A key finding is that Android’s Scudo hardened allocator deterministically rendered this vulnerability non-exploitabledue to guard pages surrounding secondary allocations. While Scudo is Android’s default allocator, used on Google Pixel and many other devices, we continue to work with partners to make it mandatory. In the meantime, we will issue CVEs of sufficient severity for vulnerabilities that could be prevented by Scudo.
In addition to protecting against overflows, Scudo’s use of guard pages helped identify this issue by changing an overflow from silent memory corruption into a noisy crash. However, we did discover a gap in our crash reporting: it failed to clearly show that the crash was a result of an overflow, which slowed down triage and response. This has been fixed, and we now have a clear signal when overflows occur into Scudo guard pages.
Unsafe Review and Training
Operating system development requires unsafe code, typically C, C++, or unsafe Rust (for example, for FFI and interacting with hardware), so simply banning unsafe code is not workable. When developers must use unsafe, they should understand how to do so soundly and responsibly
To that end, we are adding a new deep dive on unsafe code to our Comprehensive Rust training. This new module, currently in development, aims to teach developers how to reason about unsafe Rust code, soundness and undefined behavior, as well as best practices like safety comments and encapsulating unsafe code in safe abstractions.
Better understanding of unsafe Rust will lead to even higher quality and more secure code across the open source software ecosystem and within Android. As we'll discuss in the next section, our unsafe Rust is already really quite safe. It’s exciting to consider just how high the bar can go.
Comparing Vulnerability Densities
This near-miss inevitably raises the question: "If Rust can have memory safety vulnerabilities, then what’s the point?"
The point is that the density is drastically lower. So much lower that it represents a major shift in security posture. Based on our near-miss, we can make a conservative estimate. With roughly 5 million lines of Rust in the Android platform and one potential memory safety vulnerability found (and fixed pre-release), our estimated vulnerability density for Rust is 0.2 vuln per 1 million lines (MLOC).
Our historical data for C and C++ shows a density of closer to 1,000 memory safety vulnerabilities per MLOC. Our Rust code is currently tracking at a density orders of magnitude lower: a more than 1000x reduction.
Memory safety rightfully receives significant focus because the vulnerability class is uniquely powerful and (historically) highly prevalent. High vulnerability density undermines otherwise solid security design because these flaws can be chained to bypass defenses, including those specifically targeting memory safety exploits. Significantly lowering vulnerability density does not just reduce the number of bugs; it dramatically boosts the effectiveness of our entire security architecture.
The primary security concern regarding Rust generally centers on the approximately 4% of code written within unsafe{} blocks. This subset of Rust has fueled significant speculation, misconceptions, and even theories that unsafe Rust might be more buggy than C. Empirical evidence shows this to be quite wrong.
Our data indicates that even a more conservative assumption, that a line of unsafe Rust is as likely to have a bug as a line of C or C++, significantly overestimates the risk of unsafe Rust. We don’t know for sure why this is the case, but there are likely several contributing factors:
unsafe{} doesn't actually disable all or even most of Rust’s safety checks (a common misconception).
The practice of encapsulation enables local reasoning about safety invariants.
The additional scrutiny that unsafe{} blocks receive.
Final Thoughts
Historically, we had to accept a trade-off: mitigating the risks of memory safety defects required substantial investments in static analysis, runtime mitigations, sandboxing, and reactive patching. This approach attempted to move fast and then pick up the pieces afterwards. These layered protections were essential, but they came at a high cost to performance and developer productivity, while still providing insufficient assurance.
While C and C++ will persist, and both software and hardware safety mechanisms remain critical for layered defense, the transition to Rust is a different approach where the more secure path is also demonstrably more efficient. Instead of moving fast and then later fixing the mess, we can move faster while fixing things. And who knows, as our code gets increasingly safe, perhaps we can start to reclaim even more of that performance and productivity that we exchanged for security, all while also improving security.

The Business of Secrets: Adventures in Selling Encryption Around the World by Fred Kinch (May 24, 2024)
From the vantage point of today, it’s surreal reading about the commercial cryptography business in the 1970s. Nobody knew anything. The manufacturers didn’t know whether the cryptography they sold was any good. The customers didn’t know whether the crypto they bought was any good. Everyone pretended to know, thought they knew, or knew better than to even try to know.
The Business of Secrets is the self-published memoirs of Fred Kinch. He was founder and vice president of—mostly sales—at a US cryptographic hardware company called Datotek, from company’s founding in 1969 until 1982. It’s mostly a disjointed collection of stories about the difficulties of selling to governments worldwide, along with descriptions of the highs and (mostly) lows of foreign airlines, foreign hotels, and foreign travel in general. But it’s also about encryption...
Since its original release in 2009, checksec has become widely used in the software security community, proving useful in CTF challenges, security posturing, and general binary analysis. The tool inspects executables to determine which exploit mitigations (e.g., ASLR, DEP, stack canaries, etc.) are enabled, rapidly gauging a program’s defensive hardening. This success inspired numerous spinoffs: a contemporary Go implementation, Trail of Bits’ Winchecksec for PE binaries, and various scripts targeting Apple’s Mach-O binary format. However, this created an unwieldy ecosystem where security professionals must juggle multiple tools, each with different interfaces, dependencies, and feature sets.
During my summer internship at Trail of Bits, I built Checksec Anywhere to consolidate this fragmented ecosystem into a consistent and accessible platform. Checksec Anywhere brings ELF, PE, and Mach-O analysis directly to your browser. It runs completely locally: no accounts, no uploads, no downloads. It is fast (analyzes thousands of binaries in seconds) and private, and lets you share results with a simple URL.
Using Checksec Anywhere
To use Checksec Anywhere, just drag and drop a file or folder directly into the browser. Results are instantly displayed with color-coded messages reflecting finding severity. All processing happens locally in your browser; at no point is data sent to Trail of Bits or anyone else.
Figure 1: Uploading 746 files from /usr/bin to Checksec Anywhere
Key features of Checksec Anywhere
Multi-format analysis
Checksec Anywhere performs comprehensive binary analysis across ELF, PE, and Mach-O formats from a single interface, providing analysis tailored to each platform’s unique security mechanisms. This includes traditional checks like stack canaries and PIE for ELF binaries, GS cookies and Control Flow Guard for PE files, and ARC and code signing for Mach-O executables. For users familiar with the traditional checksec family of tools, Checksec Anywhere reports maintain consistency with prior reporting nomenclature.
Privacy-first
Unlike many browser-accessible tools that simply provide a web interface to server-side processing, Checksec Anywhere ensures that your binaries never leave your machine by performing all analysis directly in the browser. Report generation also happens locally, and shareable links do not reveal binary content.
Performance by design
From browser upload to complete security report, Checksec Anywhere is designed to rapidly process multiple files. Since Checksec Anywhere runs locally, the exact performance depends on your machine… but it’s fast. On a modern MacBook Pro it can analyze thousands of files in mere seconds.
Enhanced accessibility
Checksec Anywhere eliminates installation barriers by offering an entirely browser-based interface and features designed to provide accessibility:
Shareable results: Generate static URLs for any report view, enabling secure collaboration without exposing binaries.
SARIF export: Generate reports in SARIF format for integration with CI/CD pipelines and other security tools. These reports are also generated entirely on your local machine.
Simple batch processing: Drag and drop entire directories for simple bulk analysis.
Tabbed interface: Manage multiple analyses simultaneously with an intuitive UI.
Figure 2: Tabbed interface for managing multiple analyses
Technical architecture
Checksec Anywhere leverages modern web technologies to deliver native-tool performance in the browser:
Rust core: Checksec Anywhere is built on the checksec.rs foundation, using well-established crates like Goblin for binary parsing and iced_x86 for disassembly.
WebAssembly bridge: The Rust code is compiled to Wasm using wasm-pack, exposing low-level functionality through a clean JavaScript API.
Extensible design: Per-format processing architecture allows easy addition of new binary types and security checks.
Advanced analysis: Checksec Anywhere performs disassembly to enable deeper introspection (like to detect stack protection in PE binaries).
With an established infrastructure for cross-platform binary analysis and reporting, we can easily add new features and extensions. If you have pull requests, we’d love to review and merge them.
Additional formats
A current major blind spot is lack of support for mobile binary formats like Android APK and iOS IPA. Adding analysis for these formats would address the expanding mobile threat landscape. Similarly, specialized handling of firmware binaries and bootloaders would extend coverage to critical system-level components in mobile and embedded devices.
Additional security properties
Checksec Anywhere is designed to add new checks as researchers discover new attack methods. For example, recent research has uncovered multiple mechanisms by which compiler optimizations violate constant-time execution guarantees, prompting significant discussion within the compiler community (see this LLVM discourse thread, for example). As these issues are addressed, constant-time security checks can be integrated into Checksec Anywhere, providing immediate feedback on whether a given binary is resistant to timing attacks.
Try it out
Checksec Anywhere eliminates the overhead of managing format-specific security analysis tools while providing immediate access to comprehensive binary security reports. No installation, no dependencies, no compromises on privacy or performance. Visit checksec-anywhere.com and try it now!
I’d like to extend a special thank you to my mentors William Woodruff and Bradley Swain for their guidance and support throughout my summer here at Trail of Bits!

We’re releasing Slither-MCP, a new tool that augments LLMs with Slither’s unmatched static analysis engine. Slither-MCP benefits virtually every use case for LLMs by exposing Slither’s static analysis API via tools, allowing LLMs to find critical code faster, navigate codebases more efficiently, and ultimately improve smart contract authoring and auditing performance.
How Slither-MCP works
Slither-MCP is an MCP server that wraps Slither’s static analysis functionality, making it accessible through the Model Context Protocol. It can analyze Solidity projects (Foundry, Hardhat, etc.) and generate comprehensive metadata about contracts, functions, inheritance hierarchies, and more.
When an LLM uses Slither-MCP, it no longer has to rely on rudimentary tools like grep and read_file to identify where certain functions are implemented, who a function’s callers are, and other complex, error-prone tasks.
Because LLMs are probabilistic systems, in most cases they are only probabilistically correct. Slither-MCP helps set a ground truth for LLM-based analysis using traditional static analysis: it reduces token use and increases the probability a prompt is answered correctly.
Example: Simplifying an auditing task
Consider a project that contains two ERC20 contracts: one used in the production deployment, and one used in tests. An LLM is tasked with auditing a contract’s use of ERC20.transfer(), and needs to locate the source code of the function.
Without Slither-MCP, the LLM has two options:
Try to resolve the import path of the ERC20 contract, then try to call read_file to view the source of ERC20.transfer(). This option usually requires multiple calls to read_file, especially if the call to ERC20.transfer() is through a child contract that is inherited from ERC20. Regardless, this option will be error-prone and tool call intensive.
Try to use the grep tool to locate the implementation of ERC20.transfer(). Depending on how the grep tool call is structured, it may return the wrong ERC20 contract.
Both options are non-ideal, error-prone, and not likely to be correct with a high interval of confidence.
Using Slither-MCP, the LLM simply calls get_function_source to locate the source code of the function.
Simple setup
Slither-MCP is easy to set up, and can be added to Claude Code using the following command:
For now, Slither-MCP exposes a subset of Slither’s analysis engine that we believe LLMs would have the most benefit consuming. This includes the following functionalities:
Extracting the source code of a given contract or function for analysis
Identifying the callers and callees of a function
Identifying the contract’s derived and inherited members
Locating potential implementations of a function based on signature (e.g., finding concrete definitions for IOracle.price(...))
Running Slither’s exhaustive suite of detectors and filtering the results
Slither-MCP is licensed AGPLv3, the same license Slither uses. This license requires publishing the full source code of your application if you use it in a web service or SaaS product. For many tools, this isn’t an acceptable compromise.
To help remediate this, we are now offering dual licensing for both Slither and Slither-MCP. By offering dual licensing, Slither and Slither-MCP can be used to power LLM-based security web apps without publishing your entire source code, and without having to spend years reproducing its feature set.
If you are currently using Slither in your commercial web application, or are interested in using it, please reach out.
Short-finned pilot wales (Globicephala macrorhynchus) eat at lot of squid:
To figure out a short-finned pilot whale’s caloric intake, Gough says, the team had to combine data from a variety of sources, including movement data from short-lasting tags, daily feeding rates from satellite tags, body measurements collected via aerial drones, and sifting through the stomachs of unfortunate whales that ended up stranded on land.
Once the team pulled all this data together, they estimated that a typical whale will eat between 82 and 202 squid a day. To meet their energy needs, a whale will have to consume an average of 140 squid a day. Annually, that’s about 74,000 squid per whale. For all the whales in the area, that amounts to about 88,000 tons of squid eaten every year...

As AI capabilities grow, we must delineate the roles that should remain exclusively human. The line seems to be between fact-based decisions and judgment-based decisions.
For example, in a medical context, if an AI was demonstrably better at reading a test result and diagnosing cancer than a human, you would take the AI in a second. You want the more accurate tool. But justice is harder because justice is inherently a human quality in a way that “Is this tumor cancerous?” is not.

The Trail of Bits cryptography team is releasing our open-source pure Go implementations of ML-DSA (FIPS-204) and SLH-DSA (FIPS-205), two NIST-standardized post-quantum signature algorithms. These implementations have been engineered and reviewed by several of our cryptographers, so if you or your organization is looking to transition to post-quantum support for digital signatures, try them out!
This post will detail some of the work we did to ensure the implementations are constant time. These tricks specifically apply to the ML-DSA (FIPS-204) algorithm, protecting from attacks like KyberSlash, but they also apply to any cryptographic algorithm that requires branching or division.
The road to constant-time FIPS-204
SLH-DSA (FIPS-205) is relatively easy to implement without introducing side channels, as it’s based on pseudorandom functions built from hash functions, but the ML-DSA (FIPS-204) specification includes several integer divisions, which require more careful consideration.
Division was the root cause of a timing attack called KyberSlash that impacted early implementations of Kyber, which later became ML-KEM (FIPS-203). We wanted to avoid this risk entirely in our implementation.
Each of the ML-DSA parameter sets (ML-DSA-44, ML-DSA-65, and ML-DSA-87) include several other parameters that affect the behavior of the algorithm. One of those is called $γ_2$, the low-order rounding range.
$γ_2$ is always an integer, but its value depends on the parameter set. For ML-DSA-44, $γ_2$ is equal to 95232. For ML-DSA-65 and ML-DSA-87, $γ_2$ is equal to 261888.
ML-DSA specifies an algorithm called Decompose, which converts a field element into two components ($r_1$, $r_0$) such that $(r_1 \cdot 2γ_2) + r_0$ equals the original field element. This requires dividing by $2γ_2$ in one step and calculating the remainder of $2γ_2$ in another.
If you ask an AI to implement the Decompose algorithm for you, you will get something like this:
// This code sample was generated by Claude AI.// Not secure -- DO NOT USE.//// Here, `alpha` is equal to `2 * γ2`, and `r` is the field element:funcDecomposeUnsafe(r,alphaint32)(r1,r0int32){// Ensure r is in range [0, q-1]r=r%qifr<0{r+=q}// Center r around 0 (map to range [-(q-1)/2, (q-1)/2])ifr>(q-1)/2{r=r-q}// Compute r1 = round(r/alpha) where round is rounding to nearest// with ties broken towards zeroifr>=0{r1=(r+alpha/2)/alpha}else{r1=(r-alpha/2+1)/alpha}// Compute r0 = r - r1*alphar0=r-r1*alpha// Adjust r1 if r0 is too largeifr0>alpha/2{r1++r0-=alpha}elseifr0<-alpha/2{r1--r0+=alpha}returnr1,r0}
However, this violates cryptography engineering best practices:
This code flagrantly uses division and modulo operators.
It contains several branches based on values derived from the field element.
Zen and the art of branchless cryptography
The straightforward approach to preventing branches in any cryptography algorithm is to always perform both sides of the condition (true and false) and then use a constant-time conditional swap based on the condition to obtain the correct result. This involves bit masking, two’s complement, and exclusive OR (XOR).
Removing the branches from this function looks something like this:
// This is another AI-generated code sample.// Not secure -- DO NOT USE.funcDecomposeUnsafeBranchless(r,alphaint32)(r1,r0int32){// Ensure r is in range [0, q-1]r=r%qr+=q&(r>>31)// Add q if r < 0 (using arithmetic right shift)// Center r around 0 (map to range [-(q-1)/2, (q-1)/2])mask:=-((r-(q-1)/2-1)>>31)// mask = -1 if r > (q-1)/2, else 0r-=q&mask// Compute r1 = round(r/alpha) with ties broken towards zero// For r >= 0: r1 = (r + alpha/2) / alpha// For r < 0: r1 = (r - alpha/2 + 1) / alphasignMask:=r>>31// signMask = -1 if r < 0, else 0offset:=(alpha/2)+(signMask&(-alpha/2+1))// alpha/2 if r >= 0, else -alpha/2 + 1r1=(r+offset)/alpha// Compute r0 = r - r1*alphar0=r-r1*alpha// Adjust r1 if r0 is too large (branch-free)// If r0 > alpha/2: r1++, r0 -= alpha// If r0 < -alpha/2: r1--, r0 += alpha// Check if r0 > alpha/2adjustUp:=-((r0-alpha/2-1)>>31)// -1 if r0 > alpha/2, else 0r1+=adjustUp&1r0-=adjustUp&alpha// Check if r0 < -alpha/2adjustDown:=-((-r0-alpha/2-1)>>31)// -1 if r0 < -alpha/2, else 0r1-=adjustDown&1r0+=adjustDown&alphareturnr1,r0}
That solves our conditional branching problem; however, we aren’t done yet. There are still the troublesome division operators.
Undivided by time: Division-free algorithms
The previous trick of constant-time conditional swaps can be leveraged to implement integer division in constant time as well.
funcDivConstTime32(nuint32,duint32)(uint32,uint32){quotient:=uint32(0)R:=uint32(0)// We are dealing with 32-bit integers, so we iterate 32 timesb:=uint32(32)i:=bforrangeb{i--R<<=1// R(0) := N(i)R|=((n>>i)&1)// swap from Sub32() will look like this:// if remainder > d, swap == 0// if remainder == d, swap == 0// if remainder < d, swap == 1Rprime,swap:=bits.Sub32(R,d,0)// invert logic of sub32 for conditional swapswap^=1/*
Desired:
if R > D then swap = 1
if R == D then swap = 1
if R < D then swap = 0
*/// Qprime := Q// Qprime(i) := 1Qprime:=quotientQprime|=(1<<i)// Conditional swap:mask:=uint32(-swap)R^=((Rprime^R)&mask)quotient^=((Qprime^quotient)&mask)}returnquotient,R}
This works as expected, but it’s slow, since it requires a full loop iteration to calculate each bit of the quotient and remainder. We can do better.
One neat optimization trick: Barrett reduction
Since the value $γ_2$ is fixed for a given parameter set, and the division and modulo operators are performed against $2γ_2$, we can use Barrett reduction with precomputed values instead of division.
Barrett reduction involves multiplying by a reciprocal (in our case, $2^{64}/2γ_2$) and then performing up to two corrective subtractions to obtain a remainder. The quotient is produced as a byproduct of this calculation.
// Calculates (n/d, n%d) given (n, d)funcDivBarrett(numerator,denominatoruint32)(uint32,uint32){// Since d is always 2 * gamma2, we can precompute (2^64 / d) and use itvarreciprocaluint64switchdenominator{case190464:// 2 * 95232reciprocal=96851604889688case523776:// 2 * 261888reciprocal=35184372088832default:// Fallback to slow divisionreturnDivConstTime32(numerator,denominator)}// Barrett reductionhi,_:=bits.Mul64(uint64(numerator),reciprocal)quo:=uint32(hi)r:=numerator-quo*denominator// Two correction steps using bits.Sub32 (constant-time)fori:=0;i<2;i++{newR,borrow:=bits.Sub32(r,denominator,0)correction:=borrow^1// 1 if r >= d, 0 if r < dmask:=uint32(-correction)quo+=mask&1r^=mask&(newR^r)// Conditional swap using XOR}returnquo,r}
The availability of post-quantum signature algorithms in Go is a step toward a future where internet communications remain secure, even if a cryptography-relevant quantum computer is ever developed.

Last year, we wrote about why a memory safety strategy that focuses on vulnerability prevention in new code quickly yields durable and compounding gains. This year we look at how this approach isn’t just fixing things, but helping us move faster.
The 2025 data continues to validate the approach, with memory safety vulnerabilities falling below 20% of total vulnerabilities for the first time.
<em>Updated data for 2025. This data covers first-party and third-party (open source) code changes to the Android platform across C, C++, Java, Kotlin, and Rust. This post is published a couple of months before the end of 2025, but Android’s industry-standard 90-day patch window means that these results are very likely close to final. We can and will accelerate patching when necessary.</em>
We adopted Rust for its security and are seeing a 1000x reduction in memory safety vulnerability density compared to Android’s C and C++ code. But the biggest surprise was Rust's impact on software delivery. With Rust changes having a 4x lower rollback rate and spending 25% less time in code review, the safer path is now also the faster one.
In this post, we dig into the data behind this shift and also cover:
How we’re expanding our reach: We're pushing to make secure code the default across our entire software stack. We have updates on Rust adoption in first-party apps, the Linux kernel, and firmware.
Our first rust memory safety vulnerability...almost: We'll analyze a near-miss memory safety bug in unsafe Rust: how it happened, how it was mitigated, and steps we're taking to prevent recurrence. It’s also a good chance to answer the question “if Rust can have memory safety issues, why bother at all?”
Building Better Software, Faster
Developing an operating system requires the low-level control and predictability of systems programming languages like C, C++, and Rust. While Java and Kotlin are important for Android platform development, their role is complementary to the systems languages rather than interchangeable. We introduced Rust into Android as a direct alternative to C and C++, offering a similar level of control but without many of their risks. We focus this analysis on new and actively developed code because our data shows this to be an effective approach.
When we look at development in systems languages (excluding Java and Kotlin), two trends emerge: a steep rise in Rust usage and a slower but steady decline in new C++.
Net lines of code added: Rust vs. C++, first-party Android code. This chart focuses on first-party (Google-developed) code (unlike the previous chart that included all first-party and third-party code in Android.) We only include systems languages, C/C++ (which is primarily C++), and Rust.
The chart shows that the volume of new Rust code now rivals that of C++, enabling reliable comparisons of software development process metrics. To measure this, we use the DORA1 framework, a decade-long research program that has become the industry standard for evaluating software engineering team performance. DORA metrics focus on:
Throughput: the velocity of delivering software changes.
Stability: the quality of those changes.
Cross-language comparisons can be challenging. We use several techniques to ensure the comparisons are reliable.
Similar sized changes: Rust and C++ have similar functionality density, though Rust is slightly denser. This difference favors C++, but the comparison is still valid. We use Gerrit’s change size definitions.
Similar developer pools: We only consider first-party changes from Android platform developers. Most are software engineers at Google, and there is considerable overlap between pools with many contributing in both.
Track trends over time: As Rust adoption increases, are metrics changing steadily, accelerating the pace, or reverting to the mean?
Throughput
Code review is a time-consuming and high-latency part of the development process. Reworking code is a primary source of these costly delays. Data shows that Rust code requires fewer revisions. This trend has been consistent since 2023. Rust changes of a similar size need about 20% fewer revisions than their C++ counterparts.
In addition, Rust changes currently spend about 25% less time in code review compared to C++. We speculate that the significant change in favor of Rust between 2023 and 2024 is due to increased Rust expertise on the Android team.
While less rework and faster code reviews offer modest productivity gains, the most significant improvements are in the stability and quality of the changes.
Stability
Stable and high-quality changes differentiate Rust. DORA uses rollback rate for evaluating change stability. Rust's rollback rate is very low and continues to decrease, even as its adoption in Android surpasses C++.
For medium and large changes, the rollback rate of Rust changes in Android is ~4x lower than C++. This low rollback rate doesn't just indicate stability; it actively improves overall development throughput. Rollbacks are highly disruptive to productivity, introducing organizational friction and mobilizing resources far beyond the developer who submitted the faulty change. Rollbacks necessitate rework and more code reviews, can also lead to build respins, postmortems, and blockage of other teams. Resulting postmortems often introduce new safeguards that add even more development overhead.
In a self-reported survey from 2022, Google software engineers reported that Rust is both easier to review and more likely to be correct. The hard data on rollback rates and review times validates those impressions.
Putting it all together
Historically, security improvements often came at a cost. More security meant more process, slower performance, or delayed features, forcing trade-offs between security and other product goals. The shift to Rust is different: we are significantly improving security and key development efficiency and product stability metrics.
Expanding Our Reach
With Rust support now mature for building Android system services and libraries, we are focused on bringing its security and productivity advantages elsewhere.
Firmware: The combination of high privilege, performance constraints, and limited applicability of many security measures makes firmware both high-risk, and challenging to secure. Moving firmware to Rust can yield a major improvement in security. We have been deploying Rust in firmware for years now, and even released tutorials, training, and code for the wider community. We’re particularly excited about our collaboration with Arm on Rusted Firmware-A.
First-party applications: Rust is ensuring memory safety from the ground up in several security-critical Google applications, such as:
Nearby Presence: The protocol for securely and privately discovering local devices over Bluetooth is implemented in Rust and is currently running in Google Play Services.
MLS: The protocol for secure RCS messaging is implemented in Rust and will be included in the Google Messages app in a future release.
Chromium: Parsers for PNG, JSON, and web fonts have been replaced with memory-safe implementations in Rust, making it easier for Chromium engineers to deal with data from the web while following the Rule of 2.
These examples highlight Rust's role in reducing security risks, but memory-safe languages are only one part of a comprehensive memory safety strategy. We continue to employ a defense-in-depth approach, the value of which was clearly demonstrated in a recent near-miss.
Our First Rust Memory Safety Vulnerability...Almost
We recently avoided shipping our very first Rust-based memory safety vulnerability: a linear buffer overflow in CrabbyAVIF. It was a near-miss. To ensure the patch received high priority and was tracked through release channels, we assigned it the identifier CVE-2025-48530. While it’s great that the vulnerability never made it into a public release, the near-miss offers valuable lessons. The following sections highlight key takeaways from our postmortem.
Scudo Hardened Allocator for the Win
A key finding is that Android’s Scudo hardened allocator deterministically rendered this vulnerability non-exploitabledue to guard pages surrounding secondary allocations. While Scudo is Android’s default allocator, used on Google Pixel and many other devices, we continue to work with partners to make it mandatory. In the meantime, we will issue CVEs of sufficient severity for vulnerabilities that could be prevented by Scudo.
In addition to protecting against overflows, Scudo’s use of guard pages helped identify this issue by changing an overflow from silent memory corruption into a noisy crash. However, we did discover a gap in our crash reporting: it failed to clearly show that the crash was a result of an overflow, which slowed down triage and response. This has been fixed, and we now have a clear signal when overflows occur into Scudo guard pages.
Unsafe Review and Training
Operating system development requires unsafe code, typically C, C++, or unsafe Rust (for example, for FFI and interacting with hardware), so simply banning unsafe code is not workable. When developers must use unsafe, they should understand how to do so soundly and responsibly
To that end, we are adding a new deep dive on unsafe code to our Comprehensive Rust training. This new module, currently in development, aims to teach developers how to reason about unsafe Rust code, soundness and undefined behavior, as well as best practices like safety comments and encapsulating unsafe code in safe abstractions.
Better understanding of unsafe Rust will lead to even higher quality and more secure code across the open source software ecosystem and within Android. As we'll discuss in the next section, our unsafe Rust is already really quite safe. It’s exciting to consider just how high the bar can go.
Comparing Vulnerability Densities
This near-miss inevitably raises the question: "If Rust can have memory safety vulnerabilities, then what’s the point?"
The point is that the density is drastically lower. So much lower that it represents a major shift in security posture. Based on our near-miss, we can make a conservative estimate. With roughly 5 million lines of Rust in the Android platform and one potential memory safety vulnerability found (and fixed pre-release), our estimated vulnerability density for Rust is 0.2 vuln per 1 million lines (MLOC).
Our historical data for C and C++ shows a density of closer to 1,000 memory safety vulnerabilities per MLOC. Our Rust code is currently tracking at a density orders of magnitude lower: a more than 1000x reduction.
Memory safety rightfully receives significant focus because the vulnerability class is uniquely powerful and (historically) highly prevalent. High vulnerability density undermines otherwise solid security design because these flaws can be chained to bypass defenses, including those specifically targeting memory safety exploits. Significantly lowering vulnerability density does not just reduce the number of bugs; it dramatically boosts the effectiveness of our entire security architecture.
The primary security concern regarding Rust generally centers on the approximately 4% of code written within unsafe{} blocks. This subset of Rust has fueled significant speculation, misconceptions, and even theories that unsafe Rust might be more buggy than C. Empirical evidence shows this to be quite wrong.
Our data indicates that even a more conservative assumption, that a line of unsafe Rust is as likely to have a bug as a line of C or C++, significantly overestimates the risk of unsafe Rust. We don’t know for sure why this is the case, but there are likely several contributing factors:
unsafe{} doesn't actually disable all or even most of Rust’s safety checks (a common misconception).
The practice of encapsulation enables local reasoning about safety invariants.
The additional scrutiny that unsafe{} blocks receive.
Final Thoughts
Historically, we had to accept a trade-off: mitigating the risks of memory safety defects required substantial investments in static analysis, runtime mitigations, sandboxing, and reactive patching. This approach attempted to move fast and then pick up the pieces afterwards. These layered protections were essential, but they came at a high cost to performance and developer productivity, while still providing insufficient assurance.
While C and C++ will persist, and both software and hardware safety mechanisms remain critical for layered defense, the transition to Rust is a different approach where the more secure path is also demonstrably more efficient. Instead of moving fast and then later fixing the mess, we can move faster while fixing things. And who knows, as our code gets increasingly safe, perhaps we can start to reclaim even more of that performance and productivity that we exchanged for security, all while also improving security.

The Business of Secrets: Adventures in Selling Encryption Around the World by Fred Kinch (May 24, 2024)
From the vantage point of today, it’s surreal reading about the commercial cryptography business in the 1970s. Nobody knew anything. The manufacturers didn’t know whether the cryptography they sold was any good. The customers didn’t know whether the crypto they bought was any good. Everyone pretended to know, thought they knew, or knew better than to even try to know.
The Business of Secrets is the self-published memoirs of Fred Kinch. He was founder and vice president of—mostly sales—at a US cryptographic hardware company called Datotek, from company’s founding in 1969 until 1982. It’s mostly a disjointed collection of stories about the difficulties of selling to governments worldwide, along with descriptions of the highs and (mostly) lows of foreign airlines, foreign hotels, and foreign travel in general. But it’s also about encryption...
Since its original release in 2009, checksec has become widely used in the software security community, proving useful in CTF challenges, security posturing, and general binary analysis. The tool inspects executables to determine which exploit mitigations (e.g., ASLR, DEP, stack canaries, etc.) are enabled, rapidly gauging a program’s defensive hardening. This success inspired numerous spinoffs: a contemporary Go implementation, Trail of Bits’ Winchecksec for PE binaries, and various scripts targeting Apple’s Mach-O binary format. However, this created an unwieldy ecosystem where security professionals must juggle multiple tools, each with different interfaces, dependencies, and feature sets.
During my summer internship at Trail of Bits, I built Checksec Anywhere to consolidate this fragmented ecosystem into a consistent and accessible platform. Checksec Anywhere brings ELF, PE, and Mach-O analysis directly to your browser. It runs completely locally: no accounts, no uploads, no downloads. It is fast (analyzes thousands of binaries in seconds) and private, and lets you share results with a simple URL.
Using Checksec Anywhere
To use Checksec Anywhere, just drag and drop a file or folder directly into the browser. Results are instantly displayed with color-coded messages reflecting finding severity. All processing happens locally in your browser; at no point is data sent to Trail of Bits or anyone else.
Figure 1: Uploading 746 files from /usr/bin to Checksec Anywhere
Key features of Checksec Anywhere
Multi-format analysis
Checksec Anywhere performs comprehensive binary analysis across ELF, PE, and Mach-O formats from a single interface, providing analysis tailored to each platform’s unique security mechanisms. This includes traditional checks like stack canaries and PIE for ELF binaries, GS cookies and Control Flow Guard for PE files, and ARC and code signing for Mach-O executables. For users familiar with the traditional checksec family of tools, Checksec Anywhere reports maintain consistency with prior reporting nomenclature.
Privacy-first
Unlike many browser-accessible tools that simply provide a web interface to server-side processing, Checksec Anywhere ensures that your binaries never leave your machine by performing all analysis directly in the browser. Report generation also happens locally, and shareable links do not reveal binary content.
Performance by design
From browser upload to complete security report, Checksec Anywhere is designed to rapidly process multiple files. Since Checksec Anywhere runs locally, the exact performance depends on your machine… but it’s fast. On a modern MacBook Pro it can analyze thousands of files in mere seconds.
Enhanced accessibility
Checksec Anywhere eliminates installation barriers by offering an entirely browser-based interface and features designed to provide accessibility:
Shareable results: Generate static URLs for any report view, enabling secure collaboration without exposing binaries.
SARIF export: Generate reports in SARIF format for integration with CI/CD pipelines and other security tools. These reports are also generated entirely on your local machine.
Simple batch processing: Drag and drop entire directories for simple bulk analysis.
Tabbed interface: Manage multiple analyses simultaneously with an intuitive UI.
Figure 2: Tabbed interface for managing multiple analyses
Technical architecture
Checksec Anywhere leverages modern web technologies to deliver native-tool performance in the browser:
Rust core: Checksec Anywhere is built on the checksec.rs foundation, using well-established crates like Goblin for binary parsing and iced_x86 for disassembly.
WebAssembly bridge: The Rust code is compiled to Wasm using wasm-pack, exposing low-level functionality through a clean JavaScript API.
Extensible design: Per-format processing architecture allows easy addition of new binary types and security checks.
Advanced analysis: Checksec Anywhere performs disassembly to enable deeper introspection (like to detect stack protection in PE binaries).
With an established infrastructure for cross-platform binary analysis and reporting, we can easily add new features and extensions. If you have pull requests, we’d love to review and merge them.
Additional formats
A current major blind spot is lack of support for mobile binary formats like Android APK and iOS IPA. Adding analysis for these formats would address the expanding mobile threat landscape. Similarly, specialized handling of firmware binaries and bootloaders would extend coverage to critical system-level components in mobile and embedded devices.
Additional security properties
Checksec Anywhere is designed to add new checks as researchers discover new attack methods. For example, recent research has uncovered multiple mechanisms by which compiler optimizations violate constant-time execution guarantees, prompting significant discussion within the compiler community (see this LLVM discourse thread, for example). As these issues are addressed, constant-time security checks can be integrated into Checksec Anywhere, providing immediate feedback on whether a given binary is resistant to timing attacks.
Try it out
Checksec Anywhere eliminates the overhead of managing format-specific security analysis tools while providing immediate access to comprehensive binary security reports. No installation, no dependencies, no compromises on privacy or performance. Visit checksec-anywhere.com and try it now!
I’d like to extend a special thank you to my mentors William Woodruff and Bradley Swain for their guidance and support throughout my summer here at Trail of Bits!

Encryption can protect data at rest and data in transit, but does nothing for data in use. What we have are secure enclaves. I’ve written about this before:
Almost all cloud services have to perform some computation on our data. Even the simplest storage provider has code to copy bytes from an internal storage system and deliver them to the user. End-to-end encryption is sufficient in such a narrow context. But often we want our cloud providers to be able to perform computation on our raw data: search, analysis, AI model training or fine-tuning, and more. Without expensive, esoteric techniques, such as secure multiparty computation protocols or homomorphic encryption techniques that can perform calculations on encrypted data, cloud servers require access to the unencrypted data to do anything useful...

Encryption can protect data at rest and data in transit, but does nothing for data in use. What we have are secure enclaves. I’ve written about this before:
Almost all cloud services have to perform some computation on our data. Even the simplest storage provider has code to copy bytes from an internal storage system and deliver them to the user. End-to-end encryption is sufficient in such a narrow context. But often we want our cloud providers to be able to perform computation on our raw data: search, analysis, AI model training or fine-tuning, and more. Without expensive, esoteric techniques, such as secure multiparty computation protocols or homomorphic encryption techniques that can perform calculations on encrypted data, cloud servers require access to the unencrypted data to do anything useful...

The root cause of the hack was a rounding direction issue that had been present in the code for many years.
When the bug was first introduced, the threat landscape of the blockchain ecosystem was significantly different, and arithmetic issues in particular were not widely considered likely vectors for exploitation.
As low-hanging attack paths have become increasingly scarce, attackers have become more sophisticated and will continue to hunt for novel threats, such as arithmetic edge cases, in DeFi protocols.
Comprehensive invariant documentation and testing are now essential; the simple rule “rounding must favor the protocol” is no longer sufficient to catch edge cases.
This incident highlights the importance of both targeted security techniques, such as developing and maintaining fuzz suites, and holistic security practices, including monitoring and secondary controls.
What happened: Understanding the vulnerability
On November 3, 2025, attackers exploited a vulnerability in Balancer v2 to drain more than $100M across nine blockchain networks. The attack targeted a number of Balancer v2 pools, exploiting a rounding direction error. For a detailed root cause analysis, we recommend reading Certora’s blog post.
Since learning of the attack on November 3, Trail of Bits has been working closely with the Balancer team to understand the vulnerability and its implications. We independently confirmed that Balancer v3 was not affected by this vulnerability.
The 2021 audits: What we found and what we learned
In 2021, Trail of Bits conducted three security reviews of Balancer v2. The commit reviewed during the first audit, in April 2021, did not have this vulnerability present; however, we did uncover a variety of other similar rounding issues using Echidna, our smart contract fuzzer. As part of the report, we wrote an appendix (appendix H) that did a deep dive on how rounding direction and precision loss should be managed in the codebase.
In October 2021, Trail of Bits conducted a security review of Balancer’s Linear Pools (report). During that review, we identified issues with how Linear Pools consumed the Stable Math library (documented as finding TOB-BALANCER-004 in our report). However, the finding was marked as “undetermined severity.”
At the time of the audit, we couldn’t definitively determine whether the identified rounding behavior was exploitable in the Linear Pools as they were configured. We flagged the issue because we found similar ones in the first audit, and we recommended implementing comprehensive fuzz testing to ensure the rounding directions of all arithmetic operations matched expectations.
We now know that the Composable Stable Pools that were hacked on Monday were exploited using the same vulnerability that we reported in our audit. We performed a security review of the Composable Stable Pools in September 2022; however, the Stable Math library was explicitly out of scope (see the Coverage Limitations section in the report).
The above case illustrates the difficulty in evaluating the impact of a precision loss or rounding direction issue. A precision loss of 1 wei in the wrong direction may not seem significant when a fuzzer first identifies it, but in a particular case, such as a low-liquidity pool configured with specific parameters, the precision loss may be substantial enough to become profitable.
2021 to 2025: How the ecosystem has evolved
When we audited Balancer in 2021, the blockchain ecosystem’s threat landscape was much different than it is today. In particular, the industry at large did not consider rounding and arithmetic issues to be a significant risk to the ecosystem. If you look back at the biggest crypto hacks of 2021, you’ll find that the root causes were different threats: access control flaws, private key compromise (phishing), and front-end compromise.
Looking at 2022, it’s a similar story; that year in particular saw enormous hacks that drained several cross-chain bridges, either through private key compromise (phishing) or traditional smart contract vulnerabilities. To be clear, during this period, more DeFi-specific exploits, such as oracle price manipulation attacks, also occurred. However, these exploits were considered a novel threat at the time, and other DeFi exploits (such as those involving rounding issues) had not become widespread yet.
Although these rounding issues were not the most severe or widespread threat at the time, our team viewed them as a significant, underemphasized risk. This is why we reported the risk of rounding issues to Balancer (TOB-BALANCER-004), and we reported a similar issue in our 2021 audit of Uniswap v3. However, we have had to make our own improvements to account for this growing risk; for example, we’ve since tightened the ratings criteria for our Codebase Maturity evaluations. Where Balancer’s Linear pools were rated “Moderate” in 2021, we now rate codebases without comprehensive rounding strategies as having “Weak” arithmetic maturity.
Moving into 2023 and 2024, these DeFi-specific exploits, particularly rounding issues, became more widespread. In 2023, Hundred Finance protocol was completely drained due to a rounding issue. This same vulnerability was exploited several times in various protocols, including Sonne Finance, which was one of the biggest hacks of 2024. These broader industry trends were also validated in our client work at the time, where we continued to identify severe rounding issues, which is why we open-sourced roundme, a tool for human-assisted rounding direction analysis, in 2023.
Now, in 2025, arithmetic and correct precision are as critical as ever. The flaws that led to the biggest hacks of 2021 and 2022, such as private key compromise, continue to occur and remain a significant risk. However, it’s clear that several aspects of the blockchain and DeFi ecosystems have matured, and the attacks have become more sophisticated in response, particularly for major protocols like Uniswap and Balancer, which have undergone thorough testing and auditing over the last several years.
Preventing rounding issues in 2025
In 2025, rounding issues are as critical as ever, and the most robust way to protect against them is the following:
Invariant documentation
DeFi protocols should invest resources into documenting all the invariants pertaining to precision loss and rounding direction. Each of these invariants must be defended using an informal proof or explanation. The canonical invariant “rounding must favor the protocol” is insufficient to capture edge cases that may occur during a multi-operation user flow. It is best to begin documenting these invariants during the design and development phases of the product and using code reviews to collaborate with researchers to validate and extend this list. Tools like roundme can be used to identify the rounding direction required for each arithmetic operation to uphold the invariant.
Figure 1: Appendix H from our October 2021 Balancer v2 review
Here are some great resources and examples that you can follow for invariant testing your system:
Our work for Balancer v2 in 2021 contains a fixed-point rounding guide in Appendix H. This guide covers rounding direction identification, power rounding, and other helpful rounding guidance.
Our work with Curvance in 2024 is an excellent representation of documenting rounding behavior and then using fuzzing to validate it.
The invariants captured should then drive a comprehensive testing suite. Unit and integration testing should lead to 100% coverage. Mutation testing with solutions like slither-mutate and necessist can then aid in identifying any blind spots in the unit and integration testing suite. We also wrote a blog post earlier this year on how to effectively use mutation testing.
Our work for CAP Labs in 2025 contains extensive guidance in Appendix D on how to design an effective test suite that thoroughly unit, integration, and fuzz tests the system’s invariants.
Once all critical invariants are documented, they need to be validated with strong fuzzing campaigns. In our experience, fuzzing is the most effective technique for this type of invariant testing.
To learn more about how fuzzers work and how to leverage them to test your DeFi system, you can read the documentation for our fuzzers, Echidna and Medusa.
Invariant testing with formal verification
Use formal verification to obtain further guarantees for your invariant testing. These tools can be very complementary to fuzzing. For instance, limitations or abstractions from the formal model are great candidates for in-depth fuzzing.
Four Lessons for the DeFi ecosystem
This incident offers essential lessons for the entire DeFi community about building and maintaining secure systems:
1. Math and arithmetic are crucial in DeFi protocols
See the above section for guidance on how to best protect your system.
2. Maintain your fuzzing suite and inform it with the latest threat intelligence
While smart contracts may be immutable, your test suite should not. A common issue we have observed is that protocols will develop a fuzzing suite but fail to maintain it after a certain point in time. For example, a function may round up, but a future code update may require this function to now round down. A well-maintained fuzzing suite with the right invariants would aid in identifying that the function is now rounding in the wrong direction.
Beyond protections against code changes, your test suite should also evolve with the latest threat intelligence. Every time a novel hack occurs, this is intelligence that can improve your own test suite. As shown in the Sonne Finance incident, particularly for these arithmetic issues, it’s common for the same bugs (or variants of them) to be exploited many times over. You should get in the habit of revisiting your test suite in response to every novel incident to identify any gaps that you may have.
3. Design a robust monitoring and alerting system
In the event of a compromise, it is essential to have automated systems that can quickly alert on suspicious behavior and notify the relevant stakeholders. The system’s design also has significant implications for its ability to react effectively to a threat. For example, whether the system is pausable, upgradeable, or fully decentralized will directly impact what can be done in case of an incident.
4. Mitigate the impact of exploits with secondary controls
Even DeFi protocols are high-assurance software, but even high-assurance software like DeFi protocols has to accept some risks. However, risks must not be accepted without secondary controls that mitigate their impact. Pure risk acceptance without any controls is rare in high-assurance systems; every decision to accept risk should be followed by a question: “How can we protect ourselves if we were wrong to accept this risk?”
Even high-assurance software like DeFi protocols has to accept some risks, but these risks must not be accepted without secondary controls that mitigate their impact if they are exploited. Earlier this year, we wrote about using secondary controls to mitigate private key risk in Maturing your smart contracts beyond private key risk, which explains how controls such as rate limiting, time locks, pause guardians, and other secondary controls can reduce the risk of compromise and the blast radius of a hack via an unrecognized type of exploit.

The Department of Justice has indicted thirty-one people over the high-tech rigging of high-stakes poker games.
In a typical legitimate poker game, a dealer uses a shuffling machine to shuffle the cards randomly before dealing them to all the players in a particular order. As set forth in the indictment, the rigged games used altered shuffling machines that contained hidden technology allowing the machines to read all the cards in the deck. Because the cards were always dealt in a particular order to the players at the table, the machines could determine which player would have the winning hand. This information was transmitted to an off-site member of the conspiracy, who then transmitted that information via cellphone back to a member of the conspiracy who was playing at the table, referred to as the “Quarterback” or “Driver.” The Quarterback then secretly signaled this information (usually by prearranged signals like touching certain chips or other items on the table) to other co-conspirators playing at the table, who were also participants in the scheme. Collectively, the Quarterback and other players in on the scheme (i.e., the cheating team) used this information to win poker games against unwitting victims, who sometimes lost tens or hundreds of thousands of dollars at a time. The defendants used other cheating technology as well, such as a chip tray analyzer (essentially, a poker chip tray that also secretly read all cards using hidden cameras), an x-ray table that could read cards face down on the table, and special contact lenses or eyeglasses that could read pre-marked cards. ...

The Department of Justice has indicted thirty-one people over the high-tech rigging of high-stakes poker games.
In a typical legitimate poker game, a dealer uses a shuffling machine to shuffle the cards randomly before dealing them to all the players in a particular order. As set forth in the indictment, the rigged games used altered shuffling machines that contained hidden technology allowing the machines to read all the cards in the deck. Because the cards were always dealt in a particular order to the players at the table, the machines could determine which player would have the winning hand. This information was transmitted to an off-site member of the conspiracy, who then transmitted that information via cellphone back to a member of the conspiracy who was playing at the table, referred to as the “Quarterback” or “Driver.” The Quarterback then secretly signaled this information (usually by prearranged signals like touching certain chips or other items on the table) to other co-conspirators playing at the table, who were also participants in the scheme. Collectively, the Quarterback and other players in on the scheme (i.e., the cheating team) used this information to win poker games against unwitting victims, who sometimes lost tens or hundreds of thousands of dollars at a time. The defendants used other cheating technology as well, such as a chip tray analyzer (essentially, a poker chip tray that also secretly read all cards using hidden cameras), an x-ray table that could read cards face down on the table, and special contact lenses or eyeglasses that could read pre-marked cards. ...

Did you know that most modern passports are actually embedded devices containing an entire filesystem, access controls, and support for several cryptographic protocols? Such passports display a small symbol indicating an electronic machine-readable travel document (eMRTD), which digitally stores the same personal data printed in traditional passport booklets in its embedded filesystem. Beyond allowing travelers in some countries to skip a chat at border control, these documents use cryptography to prevent unauthorized reading, eavesdropping, forgery, and copying.
Figure 1: Chip Inside symbol (ICAO Doc 9303 Part 9)
This blog post describes how electronic passports work, the threats within their threat model, and how they protect against those threats using cryptography. It also discusses the implications of using electronic passports for novel applications, such as zero-knowledge identity proofs. Like many widely used electronic devices with long lifetimes, electronic passports and the systems interacting with them support insecure, legacy protocols that put passport holders at risk for both standard and novel use cases.
Electronic passport basics
A passport serves as official identity documentation, primarily for international travel. The International Civil Aviation Organization (ICAO) defines the standards for electronic passports, which (as suggested by the “Chip Inside” symbol) contain a contactless integrated circuit (IC) storing digital information. Essentially, the chip contains a filesystem with some access control to protect unauthorized reading of data. The full technical details of electronic passports are specified in ICAO Doc 9303; this blog post will mostly focus on part 10, which specifies the logical data structure (LDS), and part 11, which specifies the security mechanisms.
Figure 2: Electronic passport logical data structure (ICAO Doc 9303 Part 10)
The filesystem architecture is straightforward, comprising three file types: master files (MFs) serving as the root directory; dedicated files (DFs) functioning as subdirectories or applications; and elementary files (EFs) containing actual binary data. As shown in the above figure, some files are mandatory, whereas others are optional. This blog post will focus on the eMRTD application. The other applications are part of LDS 2.0, which would allow the digital storage of travel records (digital stamps!), electronic visas, and additional biometrics (so you can just update your picture instead of getting a whole new passport!).
How the eMRTD application works
The following figure shows the types of files the eMRTD contains:
Figure 3: Contents of the eMRTD application (ICAO Doc 9303 Part 10)
There are generic files containing common or security-related data; all other files are so-called data groups (DGs), which primarily contain personal information (most of which is also printed on your passport) and some additional security data that will become important later. All electronic passports must contain DGs 1 and 2, whereas the rest is optional.
Figure 4: DGs in the LDS (ICAO Doc 9303 Part 10, seventh edition)
Comparing the contents of DG1 and DG2 to the main passport page shows that most of the written data is stored in DG1 and the photo is stored in DG2. Additionally, there are two lines of characters at the bottom of the page called the machine readable zone (MRZ), which contains another copy of the DG1 data with some check digits, as shown in the following picture.
Figure 5: Example passport with MRZ (ICAO Doc 9303 Part 3)
Digging into the threat model
Electronic passports operate under a straightforward threat model that categorizes attackers based on physical access: those who hold a passport versus those who don’t. If you are near a passport but you do not hold it in your possession, you should not be able to do any of the following:
Read any personal information from that passport
Eavesdrop on communication that the passport has with legitimate terminals
Figure out whether it is a specific passport so you can trace its movements1
Even if you do hold one or more passports, you should not be able to do the following:
Forge a new passport with inauthentic data
Make a digital copy of the passport
Read the fingerprint (DG3) or iris (DG4) information2
Electronic passports use short-range RFID for communication (ISO 14443). You can communicate with a passport within a distance of 10–15 centimeters, but eavesdropping is possible at distances of several meters3. Because electronic passports are embedded devices, they need to be able to withstand attacks where the attacker has physical access to the device, such as elaborate side-channel and fault injection attacks. As a result, they are often certified (e.g., under Common Criteria).
We focus here on the threats against the electronic components of the passport. Passports have many physical countermeasures, such as visual effects that become visible under certain types of light. Even if someone can break the electronic security that prevents copying passports, they would still have to defeat these physical measures to make a full copy of the passport. That said, some systems (such as online systems) only interact digitally with the passport, so they do not perform any physical checks at all.
Cryptographic mechanisms
The earliest electronic passports lacked most cryptographic mechanisms. Malaysia issued the first electronic passport in 1998, which predates the first ICAO eMRTD specifications from 2003. Belgium subsequently issued the first ICAO-compliant eMRTD in 2004, which in turn predates the first cryptographic mechanism for confidentiality specified in 2005.
While we could focus solely on the most advanced cryptographic implementations, electronic passports remain in circulation for extended periods (typically 5–10 years), meaning legacy systems continue operating alongside modern solutions. This means that there are typically many old passports floating around that do not support the latest and greatest access control mechanisms4. Similarly, not all inspection systems/terminals support all of the protocols, which means passports potentially need to support multiple protocols. All protocols discussed in the following are described in more detail in ICAO Doc 9303 Part 11.
Legacy cryptography
Legacy protection mechanisms for electronic passports provide better security than what they were replacing (nothing), even though they have key shortcomings regarding confidentiality and (to a lesser extent) copying.
Legacy confidentiality protections: How basic access control fails
In order to prevent eavesdropping, you need to set up a secure channel. Typically, this is done by deriving a shared symmetric key, either from some shared knowledge, or through a key exchange. However, the passport cannot have its own static public key and send it over the communication channel, because this would enable tracing of specific passports.
Additionally, it should only be possible to set up this secure channel if you have the passport in your possession. So, what sets holders apart from others? Holders can read the physical passport page that contains the MRZ!
This brings us to the original solution to set up a secure channel with electronic passports: basic access control (BAC). When you place your passport with the photo page face down into an inspection system at the airport, it scans the page and reads the MRZ. Now, both sides derive encryption and message authentication code (MAC) keys from parts of the MRZ data using SHA-1 as a KDF. Then, they exchange freshly generated challenges and encrypt-then-MAC these challenges together with some fresh keying material to prove that both sides know the key. Finally, they derive session keys from the keying material and use them to set up the secure channel.
However, BAC fails to achieve any of its security objectives. The static MRZ is just some personal data and does not have very high entropy, which makes it guessable. Even worse, if you capture one valid exchange between passport and terminal, you can brute-force the MRZ offline by computing a bunch of unhardened hashes. Moreover, passive listeners who know the MRZ can decrypt all communications with the passport. Finally, the fact that the passport has to check both the MAC and the challenge has opened up the potential for oracle attacks that allow tracing by replaying valid terminal responses.
Forgery prevention: Got it right the first time
Preventing forgery is relatively simple. The passport contains a file called the Document Security Object (EF.SOD), which contains a list of hashes of all the Data Groups, and a signature over all these hashes. This signature comes from a key pair that has a certificate chain back to the Country Signing Certificate Authority (CSCA). The private key associated with the CSCA certificate is one of the most valuable assets in this system, because anyone in possession of this private key5 can issue legitimate passports containing arbitrary data.
The process of reading the passport, comparing all contents to the SOD, and verifying the signature and certificate chain is called passive authentication (PA). This will prove that the data in the passport was signed by the issuing country. However, it does nothing to prevent the copying of existing passports: anyone who can read a passport can copy its data into a new chip and it will pass PA. While this mechanism is listed among the legacy ones, it meets all of its objectives and is therefore still used without changes.
Legacy copying protections: They work, but some issues remain
Preventing copying requires having something in the passport that cannot be read or extracted, like the private key of a key pair. But how does a terminal know that a key pair belongs to a genuine passport? Since countries are already signing the contents of the passport for PA, they can just put the public key in one of the data groups (DG15), and use the private key to sign challenges that the terminal sends. This is called active authentication (AA). After performing both PA and AA, the terminal knows that the data in the passport (including the AA public key) was signed by the government and that the passport contains the corresponding private key.
This solution has two issues: the AA signature is not tied to the secure channel, so you can relay a signature and pretend that the passport is somewhere it’s not. Additionally, the passport signs an arbitrary challenge without knowing the semantics of this message, which is generally considered a dangerous practice in cryptography6.
Modern enhancements
Extended Access Control (EAC) fixes some of the issues related to BAC and AA. It comprises chip authentication (CA), which is a better AA, and terminal authentication (TA), which authenticates the terminal to the passport in order to protect access to the sensitive information stored in DG3 (fingerprint) and DG4 (iris). Finally, password authenticated connection establishment (PACE7, described below) replaces BAC altogether, eliminating its weaknesses.
Chip Authentication: Upgrading the secure channel
CA is very similar to AA in the sense that it requires countries to simply store a public key in one of the DGs (DG14), which is then authenticated using PA. However, instead of signing a challenge, the passport uses the key pair to perform a static-ephemeral Diffie-Hellman key exchange with the terminal, and uses the resulting keys to upgrade the secure channel from BAC. This means that passive listeners that know the MRZ cannot eavesdrop after doing CA, because they were not part of the key exchange.
Terminal Authentication: Protecting sensitive data in DG3 and DG4
Similar to the CSCA for signing things, each country has a Country Verification Certificate Authority (CVCA), which creates a root certificate for a PKI that authorizes terminals to read DG3 and DG4 in the passports of that country. Terminals provide a certificate chain for their public key and sign a challenge provided by the passport using their private key. The CVCA can authorize document verifiers (DVs) to read one or both of DG3 and DG4, which is encoded in the certificate. The DV then issues certificates to individual terminals. Without such a certificate, it is not possible to access the sensitive data in DG3 and DG4.
Password Authenticated Connection Establishment: Fixing the basic problems
The main idea behind PACE is that the MRZ, much like a password, does not have sufficient entropy to protect the data it contains. Therefore, it should not be used directly to derive keys, because this would enable offline brute-force attacks. PACE can work with various mappings, but we describe only the simplest one in the following, which is the generic mapping. Likewise, PACE can work with other passwords besides the MRZ (such as a PIN), but this blog post focuses on the MRZ.
First, both sides use the MRZ data (the password) to derive8 a password key. Next, the passport encrypts9 a nonce using the password key and sends it to the terminal, which can decrypt it if it knows the password. The terminal and passport also perform an ephemeral Diffie-Hellman key exchange. Now, both terminal and passport derive a new generator of the elliptic curve by applying the nonce as an additive tweak to the (EC)DH shared secret10. Using this new generator, the terminal and passport perform another (EC)DH to get a second shared secret. Finally, they use this second shared secret to derive session keys, which are used to authenticate the (EC)DH public keys that they used earlier on in the protocol, and to set up the secure channel. Figure 6 shows a simplified protocol diagram.
Figure 6: Simplified protocol diagram for PACE
Anyone who does not know the password cannot follow the protocol to the end, which will become apparent in the final step when they need to authenticate the data with the session keys. Before authenticating the terminal, the passport does not share any data that enables brute-forcing the password key. Non-participants who do know the password cannot derive the session keys because they do not know the ECDH private keys.
Gaps in the threat model: Why you shouldn’t give your passport to just anyone
When considering potential solutions to maintaining passports’ confidentiality and authenticity, it’s important to account for what the inspection system does with your passport, and not just the fancy cryptography the passport supports. If an inspection system performs only BAC/PACE and PA, anyone who has seen your passport could make an electronic copy and pretend to be you when interacting with this system. This is true even if your passport supports AA or CA.
Another important factor is tracing: the specifications aim to ensure that someone who does not know a passport’s PACE password (MRZ data in most cases) cannot trace that passport’s movements by interacting with it or eavesdropping on communications it has with legitimate terminals. They attempt to achieve this by ensuring that passports always provide random identifiers (e.g., as part of Type A or Type B ISO 14443 contactless communication protocols) and that the contents of publicly accessible files (e.g., those containing information necessary for performing PACE) are the same for every citizen of a particular country.
However, all of these protections go out of the window when the attacker knows the password. If you are entering another country and border control scans your passport, they can provide your passport contents to others, enabling them to track the movements of your passport. If you visit a hotel in Italy and they store a scan of your passport and get hacked, anyone with access to this information can track your passport. This method can be a bit onerous, as it requires contacting various nearby contactless communication devices and trying to authenticate to them as if they were your passport. However, some may still choose to include it in their threat models.
Some countries state in their issued passports that the holder should give it to someone else only if there is a statutory need. At Italian hotels, for example, it is sufficient to provide a prepared copy of the passport’s photo page with most data redacted (such as your photo, signature, and any personal identification numbers). In practice, not many people do this.
Even without the passport, the threat model says nothing about tracking particular groups of people. Countries typically buy large quantities of the same electronic passports, which comprise a combination of an IC and the embedded software implementing the passport specifications. This means that people from the same country likely have the same model of passport, with a unique fingerprint comprising characteristics like communication time, execution time11, supported protocols (ISO 14443 Type A vs Type B), etc. Furthermore, each country may use different parameters for PACE (supported curves or mappings, etc.), which may aid an attacker in fingerprinting different types of passports, as these parameters are stored in publicly readable files.
Security and privacy implications of zero-knowledge identity proofs
An emerging approach in both academic research and industry applications involves using zero-knowledge (ZK) proofs with identity documents, enabling verification of specific identity attributes without revealing complete document contents. This is a nice idea in theory, because this will allow proper use of passports where there is no statutory need to hand over your passport. However, there are security implications.
First of all, passports cannot generate ZK proofs by themselves, so this necessarily involves exposing your passport to a prover. Letting anyone or anything read your passport means that you downgrade your threat model with respect to that entity. So when you provide your passport to an app or website for the purposes of creating a ZK proof, you need to consider what they will do with the information in your passport. Will it be processed locally on your device, or will it be sent to a server? If the data leaves your device, will it be encrypted and only handled inside a trusted execution environment (TEE)? If so, has this whole stack been audited, including against malicious TEE operators?
Second, if the ZK proving service relies on PA for its proofs, then anyone who has ever seen your passport can pretend to be you on this service. Full security requires AA or CA. As long as there exists any service that relies only on PA, anyone whose passport data is exposed is vulnerable to impersonation. Even if the ZK proving service does not incorporate AA or CA in their proofs, they should still perform one of these procedures with the passport to ensure that only legitimate passports sign up for this service12.
Finally, the system needs to consider what happens when people share their ZK proof with others. The nice thing about a passport is that you cannot easily make copies (if AA or CA is used), but if I can allow others to use my ZK proof, then the value of the identification decreases.
It is important that such systems are audited for security, both from the point of view of the user and the service provider. If you’re implementing ZK proofs of identity documents, contact us to evaluate your design and implementation.
This is only guaranteed against people that do not know the contents of the passport. ↩︎

It is allowed to issue passports that only support the legacy access control mechanism (BAC) until the end of 2026, and issuing passports that support BAC in addition to the latest mechanism is allowed up to the end of 2027. Given that passports can be valid for, e.g., 10 years, this means that this legacy mechanism will stay relevant until the end of 2037. ↩︎
ICAO Doc 9303 part 12 recommends that these keys are “generated and stored in a highly protected, off-line CA Infrastructure.” Generally, these keys are stored on an HSM in some bunker. ↩︎
Some detractors (e.g., Germany) claim that you could exploit this practice to set up a tracing system where the terminal generates the challenge in a way that proves the passport was at a specific place at a specific time. However, proving that something was signed at a specific time (let alone in a specific place!) is difficult using cryptography, so any system requires you to trust the terminal. If you trust the terminal, you don’t need to rely on the passport’s signature. ↩︎

Figure 2: Electronic passport logical data structure (ICAO Doc 9303 Part 10)
The filesystem architecture is straightforward, comprising three file types: master files (MFs) serving as the root directory; dedicated files (DFs) functioning as subdirectories or applications; and elementary files (EFs) containing actual binary data. As shown in the above figure, some files are mandatory, whereas others are optional. This blog post will focus on the eMRTD application. The other applications are part of LDS 2.0, which would allow the digital storage of travel records (digital stamps!), electronic visas, and additional biometrics (so you can just update your picture instead of getting a whole new passport!).
How the eMRTD application works
The following figure shows the types of files the eMRTD contains:
Figure 3: Contents of the eMRTD application (ICAO Doc 9303 Part 10)
There are generic files containing common or security-related data; all other files are so-called data groups (DGs), which primarily contain personal information (most of which is also printed on your passport) and some additional security data that will become important later. All electronic passports must contain DGs 1 and 2, whereas the rest is optional.
Figure 4: DGs in the LDS (ICAO Doc 9303 Part 10, seventh edition)
Comparing the contents of DG1 and DG2 to the main passport page shows that most of the written data is stored in DG1 and the photo is stored in DG2. Additionally, there are two lines of characters at the bottom of the page called the machine readable zone (MRZ), which contains another copy of the DG1 data with some check digits, as shown in the following picture.
Figure 5: Example passport with MRZ (ICAO Doc 9303 Part 3)
Digging into the threat model
Electronic passports operate under a straightforward threat model that categorizes attackers based on physical access: those who hold a passport versus those who don’t. If you are near a passport but you do not hold it in your possession, you should not be able to do any of the following:
Read any personal information from that passport
Eavesdrop on communication that the passport has with legitimate terminals
Figure out whether it is a specific passport so you can trace its movements1
Even if you do hold one or more passports, you should not be able to do the following:
Forge a new passport with inauthentic data
Make a digital copy of the passport
Read the fingerprint (DG3) or iris (DG4) information2
Electronic passports use short-range RFID for communication (ISO 14443). You can communicate with a passport within a distance of 10–15 centimeters, but eavesdropping is possible at distances of several meters3. Because electronic passports are embedded devices, they need to be able to withstand attacks where the attacker has physical access to the device, such as elaborate side-channel and fault injection attacks. As a result, they are often certified (e.g., under Common Criteria).
We focus here on the threats against the electronic components of the passport. Passports have many physical countermeasures, such as visual effects that become visible under certain types of light. Even if someone can break the electronic security that prevents copying passports, they would still have to defeat these physical measures to make a full copy of the passport. That said, some systems (such as online systems) only interact digitally with the passport, so they do not perform any physical checks at all.
Cryptographic mechanisms
The earliest electronic passports lacked most cryptographic mechanisms. Malaysia issued the first electronic passport in 1998, which predates the first ICAO eMRTD specifications from 2003. Belgium subsequently issued the first ICAO-compliant eMRTD in 2004, which in turn predates the first cryptographic mechanism for confidentiality specified in 2005.
While we could focus solely on the most advanced cryptographic implementations, electronic passports remain in circulation for extended periods (typically 5–10 years), meaning legacy systems continue operating alongside modern solutions. This means that there are typically many old passports floating around that do not support the latest and greatest access control mechanisms4. Similarly, not all inspection systems/terminals support all of the protocols, which means passports potentially need to support multiple protocols. All protocols discussed in the following are described in more detail in ICAO Doc 9303 Part 11.
Legacy cryptography
Legacy protection mechanisms for electronic passports provide better security than what they were replacing (nothing), even though they have key shortcomings regarding confidentiality and (to a lesser extent) copying.
Legacy confidentiality protections: How basic access control fails
In order to prevent eavesdropping, you need to set up a secure channel. Typically, this is done by deriving a shared symmetric key, either from some shared knowledge, or through a key exchange. However, the passport cannot have its own static public key and send it over the communication channel, because this would enable tracing of specific passports.
Additionally, it should only be possible to set up this secure channel if you have the passport in your possession. So, what sets holders apart from others? Holders can read the physical passport page that contains the MRZ!
This brings us to the original solution to set up a secure channel with electronic passports: basic access control (BAC). When you place your passport with the photo page face down into an inspection system at the airport, it scans the page and reads the MRZ. Now, both sides derive encryption and message authentication code (MAC) keys from parts of the MRZ data using SHA-1 as a KDF. Then, they exchange freshly generated challenges and encrypt-then-MAC these challenges together with some fresh keying material to prove that both sides know the key. Finally, they derive session keys from the keying material and use them to set up the secure channel.
However, BAC fails to achieve any of its security objectives. The static MRZ is just some personal data and does not have very high entropy, which makes it guessable. Even worse, if you capture one valid exchange between passport and terminal, you can brute-force the MRZ offline by computing a bunch of unhardened hashes. Moreover, passive listeners who know the MRZ can decrypt all communications with the passport. Finally, the fact that the passport has to check both the MAC and the challenge has opened up the potential for oracle attacks that allow tracing by replaying valid terminal responses.
Forgery prevention: Got it right the first time
Preventing forgery is relatively simple. The passport contains a file called the Document Security Object (EF.SOD), which contains a list of hashes of all the Data Groups, and a signature over all these hashes. This signature comes from a key pair that has a certificate chain back to the Country Signing Certificate Authority (CSCA). The private key associated with the CSCA certificate is one of the most valuable assets in this system, because anyone in possession of this private key5 can issue legitimate passports containing arbitrary data.
The process of reading the passport, comparing all contents to the SOD, and verifying the signature and certificate chain is called passive authentication (PA). This will prove that the data in the passport was signed by the issuing country. However, it does nothing to prevent the copying of existing passports: anyone who can read a passport can copy its data into a new chip and it will pass PA. While this mechanism is listed among the legacy ones, it meets all of its objectives and is therefore still used without changes.
Legacy copying protections: They work, but some issues remain
Preventing copying requires having something in the passport that cannot be read or extracted, like the private key of a key pair. But how does a terminal know that a key pair belongs to a genuine passport? Since countries are already signing the contents of the passport for PA, they can just put the public key in one of the data groups (DG15), and use the private key to sign challenges that the terminal sends. This is called active authentication (AA). After performing both PA and AA, the terminal knows that the data in the passport (including the AA public key) was signed by the government and that the passport contains the corresponding private key.
This solution has two issues: the AA signature is not tied to the secure channel, so you can relay a signature and pretend that the passport is somewhere it’s not. Additionally, the passport signs an arbitrary challenge without knowing the semantics of this message, which is generally considered a dangerous practice in cryptography6.
Modern enhancements
Extended Access Control (EAC) fixes some of the issues related to BAC and AA. It comprises chip authentication (CA), which is a better AA, and terminal authentication (TA), which authenticates the terminal to the passport in order to protect access to the sensitive information stored in DG3 (fingerprint) and DG4 (iris). Finally, password authenticated connection establishment (PACE7, described below) replaces BAC altogether, eliminating its weaknesses.
Chip Authentication: Upgrading the secure channel
CA is very similar to AA in the sense that it requires countries to simply store a public key in one of the DGs (DG14), which is then authenticated using PA. However, instead of signing a challenge, the passport uses the key pair to perform a static-ephemeral Diffie-Hellman key exchange with the terminal, and uses the resulting keys to upgrade the secure channel from BAC. This means that passive listeners that know the MRZ cannot eavesdrop after doing CA, because they were not part of the key exchange.
Terminal Authentication: Protecting sensitive data in DG3 and DG4
Similar to the CSCA for signing things, each country has a Country Verification Certificate Authority (CVCA), which creates a root certificate for a PKI that authorizes terminals to read DG3 and DG4 in the passports of that country. Terminals provide a certificate chain for their public key and sign a challenge provided by the passport using their private key. The CVCA can authorize document verifiers (DVs) to read one or both of DG3 and DG4, which is encoded in the certificate. The DV then issues certificates to individual terminals. Without such a certificate, it is not possible to access the sensitive data in DG3 and DG4.
Password Authenticated Connection Establishment: Fixing the basic problems
The main idea behind PACE is that the MRZ, much like a password, does not have sufficient entropy to protect the data it contains. Therefore, it should not be used directly to derive keys, because this would enable offline brute-force attacks. PACE can work with various mappings, but we describe only the simplest one in the following, which is the generic mapping. Likewise, PACE can work with other passwords besides the MRZ (such as a PIN), but this blog post focuses on the MRZ.
First, both sides use the MRZ data (the password) to derive8 a password key. Next, the passport encrypts9 a nonce using the password key and sends it to the terminal, which can decrypt it if it knows the password. The terminal and passport also perform an ephemeral Diffie-Hellman key exchange. Now, both terminal and passport derive a new generator of the elliptic curve by applying the nonce as an additive tweak to the (EC)DH shared secret10. Using this new generator, the terminal and passport perform another (EC)DH to get a second shared secret. Finally, they use this second shared secret to derive session keys, which are used to authenticate the (EC)DH public keys that they used earlier on in the protocol, and to set up the secure channel. Figure 6 shows a simplified protocol diagram.
Figure 6: Simplified protocol diagram for PACE
Anyone who does not know the password cannot follow the protocol to the end, which will become apparent in the final step when they need to authenticate the data with the session keys. Before authenticating the terminal, the passport does not share any data that enables brute-forcing the password key. Non-participants who do know the password cannot derive the session keys because they do not know the ECDH private keys.
Gaps in the threat model: Why you shouldn’t give your passport to just anyone
When considering potential solutions to maintaining passports’ confidentiality and authenticity, it’s important to account for what the inspection system does with your passport, and not just the fancy cryptography the passport supports. If an inspection system performs only BAC/PACE and PA, anyone who has seen your passport could make an electronic copy and pretend to be you when interacting with this system. This is true even if your passport supports AA or CA.
Another important factor is tracing: the specifications aim to ensure that someone who does not know a passport’s PACE password (MRZ data in most cases) cannot trace that passport’s movements by interacting with it or eavesdropping on communications it has with legitimate terminals. They attempt to achieve this by ensuring that passports always provide random identifiers (e.g., as part of Type A or Type B ISO 14443 contactless communication protocols) and that the contents of publicly accessible files (e.g., those containing information necessary for performing PACE) are the same for every citizen of a particular country.
However, all of these protections go out of the window when the attacker knows the password. If you are entering another country and border control scans your passport, they can provide your passport contents to others, enabling them to track the movements of your passport. If you visit a hotel in Italy and they store a scan of your passport and get hacked, anyone with access to this information can track your passport. This method can be a bit onerous, as it requires contacting various nearby contactless communication devices and trying to authenticate to them as if they were your passport. However, some may still choose to include it in their threat models.
Some countries state in their issued passports that the holder should give it to someone else only if there is a statutory need. At Italian hotels, for example, it is sufficient to provide a prepared copy of the passport’s photo page with most data redacted (such as your photo, signature, and any personal identification numbers). In practice, not many people do this.
Even without the passport, the threat model says nothing about tracking particular groups of people. Countries typically buy large quantities of the same electronic passports, which comprise a combination of an IC and the embedded software implementing the passport specifications. This means that people from the same country likely have the same model of passport, with a unique fingerprint comprising characteristics like communication time, execution time11, supported protocols (ISO 14443 Type A vs Type B), etc. Furthermore, each country may use different parameters for PACE (supported curves or mappings, etc.), which may aid an attacker in fingerprinting different types of passports, as these parameters are stored in publicly readable files.
Security and privacy implications of zero-knowledge identity proofs
An emerging approach in both academic research and industry applications involves using zero-knowledge (ZK) proofs with identity documents, enabling verification of specific identity attributes without revealing complete document contents. This is a nice idea in theory, because this will allow proper use of passports where there is no statutory need to hand over your passport. However, there are security implications.
First of all, passports cannot generate ZK proofs by themselves, so this necessarily involves exposing your passport to a prover. Letting anyone or anything read your passport means that you downgrade your threat model with respect to that entity. So when you provide your passport to an app or website for the purposes of creating a ZK proof, you need to consider what they will do with the information in your passport. Will it be processed locally on your device, or will it be sent to a server? If the data leaves your device, will it be encrypted and only handled inside a trusted execution environment (TEE)? If so, has this whole stack been audited, including against malicious TEE operators?
Second, if the ZK proving service relies on PA for its proofs, then anyone who has ever seen your passport can pretend to be you on this service. Full security requires AA or CA. As long as there exists any service that relies only on PA, anyone whose passport data is exposed is vulnerable to impersonation. Even if the ZK proving service does not incorporate AA or CA in their proofs, they should still perform one of these procedures with the passport to ensure that only legitimate passports sign up for this service12.
Finally, the system needs to consider what happens when people share their ZK proof with others. The nice thing about a passport is that you cannot easily make copies (if AA or CA is used), but if I can allow others to use my ZK proof, then the value of the identification decreases.
It is important that such systems are audited for security, both from the point of view of the user and the service provider. If you’re implementing ZK proofs of identity documents, contact us to evaluate your design and implementation.
This is only guaranteed against people that do not know the contents of the passport. ↩︎

It is allowed to issue passports that only support the legacy access control mechanism (BAC) until the end of 2026, and issuing passports that support BAC in addition to the latest mechanism is allowed up to the end of 2027. Given that passports can be valid for, e.g., 10 years, this means that this legacy mechanism will stay relevant until the end of 2037. ↩︎
ICAO Doc 9303 part 12 recommends that these keys are “generated and stored in a highly protected, off-line CA Infrastructure.” Generally, these keys are stored on an HSM in some bunker. ↩︎
Some detractors (e.g., Germany) claim that you could exploit this practice to set up a tracing system where the terminal generates the challenge in a way that proves the passport was at a specific place at a specific time. However, proving that something was signed at a specific time (let alone in a specific place!) is difficult using cryptography, so any system requires you to trust the terminal. If you trust the terminal, you don’t need to rely on the passport’s signature. ↩︎

As Cybersecurity Awareness Month wraps up, we’re focusing on one of today’s most pervasive digital threats: mobile scams. In the last 12 months, fraudsters have used advanced AI tools to create more convincing schemes, resulting in over $400 billion in stolen funds globally.¹
For years, Android has been on the frontlines in the battle against scammers, using the best of Google AI to build proactive, multi-layered protections that can anticipate and block scams before they reach you. Android’s scam defenses protect users around the world from over 10 billion suspected malicious calls and messages every month2. In addition, Google continuously performs safety checks to maintain the integrity of the RCS service. In the past month alone, this ongoing process blocked over 100 million suspicious numbers from using RCS, stopping potential scams before they could even be sent.
To show how our scam protections work in the real world, we asked users and independent security experts to compare how well Android and iOS protect you from these threats. We're also releasing a new report that explains how modern text scams are orchestrated, helping you understand the tactics fraudsters use and how to spot them.
Survey shows Android users’ confidence in scam protections
Google and YouGov3 surveyed 5,000 smartphone users across the U.S., India, and Brazil about their experiences. The findings were clear: Android users reported receiving fewer scam texts and felt more confident that their device was keeping them safe.
Android users were 58% more likely than iOS users to say they had not received any scam texts in the week prior to the survey. The advantage was even stronger on Pixel, where users were 96% more likely than iPhone owners to report zero scam texts.
At the other end of the spectrum, iOS users were 65% more likely than Android users to report receiving three or more scam texts in a week. The difference became even more pronounced when comparing iPhone to Pixel, with iPhone users 136% more likely to say they had received a heavy volume of scam messages.
Android users were 20% more likely than iOS users to describe their device’s scam protections as “very effective” or “extremely effective.” When comparing Pixel to iPhone, iPhone users were 150% more likely to say their device was not effective at all in stopping mobile fraud.

Security researchers and analysts highlight Android’s AI-driven safeguards against sophisticated scams
In a recent evaluation by Counterpoint Research4, a global technology market research firm, Android smartphones were found to have the most AI-powered protections. The independent study compared the latest Pixel, Samsung, Motorola, and iPhone devices, and found that Android provides comprehensive AI-driven safeguards across ten key protection areas, including email protections, browsing protections, and on-device behavioral protections. By contrast, iOS offered AI-powered protections in only two categories. You can see the full comparison in the visual below.

Cybersecurity firm Leviathan Security Group conducted a funded evaluation5 of scam and fraud protection on the iPhone 17, Moto Razr+ 2025, Pixel 10 Pro, and Samsung Galaxy Z Fold 7. Their analysis found that Android smartphones, led by the Pixel 10 Pro, provide the highest level of default scam and fraud protection.The report particularly noted Android's robust call screening, scam detection, and real-time scam warning authentication capabilities as key differentiators. Taken together, these independent expert assessments conclude that Android’s AI-driven safeguards provide more comprehensive and intelligent protection against mobile scams.

Why Android users see fewer scams
Android’s proactive protections work across the platform to help you stay ahead of threats with the best of Google AI.
Here’s how they work:
Keeping your messages safe: Google Messages automatically filters known spam by analyzing sender reputation and message content, moving suspicious texts directly to your "spam & blocked" folder to keep them out of sight. For more complex threats, Scam Detection uses on-device AI to analyze messages from unknown senders for patterns of conversational scams (like pig butchering) and provide real-time warnings6. This helps secure your privacy while providing a robust shield against text scams. As an extra safeguard, Google Messages also helps block suspicious links in messages that are determined to be spam or scams.
Combatting phone call scams:Phone by Google automatically blocks known spam calls so your phone never even rings, while Call Screen5 can answer the call on your behalf to identify fraudsters. If you answer, the protection continues with Scam Detection, which uses on-device AI to provide real-time warnings for suspicious conversational patterns6. This processing is completely ephemeral, meaning no call content is ever saved or leaves your device. Android also helps stop social engineering during the call itself by blocking high-risk actions6like installing untrusted apps or disabling security settings, and warns you if your screen is being shared unknowingly.
These safeguards are built directly into the core of Android, alongside other features like real-time app scanning in Google Play Protect and enhanced Safe Browsing in Chrome using LLMs. With Android, you can trust that you have intelligent, multi-layered protection against scams working for you.
Android is always evolving to keep you one step ahead of scams
In a world of evolving digital threats, you deserve to feel confident that your phone is keeping you safe. That’s why we use the best of Google AI to build intelligent protections that are always improving and work for you around the clock, so you can connect, browse, and communicate with peace of mind.

Trail of Bits is disclosing vulnerabilities in eight different confidential computing systems that use Linux Unified Key Setup version 2 (LUKS2) for disk encryption. Using these vulnerabilities, a malicious actor with access to storage disks can extract all confidential data stored on that disk and can modify the contents of the disk arbitrarily. The vulnerabilities are caused by malleable metadata headers that allow an attacker to trick a trusted execution environment guest into encrypting secret data with a null cipher.
The following CVEs are associated with this disclosure:
We also notified the Confidential Containers project, who indicated that the relevant code, part of the guest-components repository, is not currently used in production.
Users of these confidential computing frameworks should update to the latest version. Consumers of remote attestation reports should disallow pre-patch versions in attestation reports.
Exploitation of this issue requires write access to encrypted disks. We do not have any indication that this issue has been exploited in the wild.
These systems all use trusted execution environments such as AMD SEV-SNP and Intel TDX to protect a confidential Linux VM from a potentially malicious host. Each relies on LUKS2 to protect disk volumes used to hold the VM’s persistent state. LUKS2 is a disk encryption format originally designed for at-rest encryption of PC and server hard disks. We found that LUKS is not always secure in settings where the disk is subject to modifications by an attacker.
Confidential VMs
The affected systems are Linux-based confidential virtual machines (CVMs). These are not interactive Linux boxes with user logins; they are specialized automated systems designed to handle secrets while running in an untrusted environment. Typical use cases are private AI inference, private blockchains, or multi-party data collaboration. Such a system should satisfy the following requirements:
Confidentiality: The host OS should not be able to read memory or data inside the CVM.
Integrity: The host OS should not be able to interfere with the logical operation of the CVM.
Authenticity: A remote party should be able to verify that they are interacting with a genuine CVM running the expected program.
Remote users verify the authenticity of a CVM via a remote attestation process, in which the secure hardware generates a “quote” signed by a secret key provisioned by the hardware manufacturer. This quote contains measurements of the CVM configuration and code. If an attacker with access to the host machine can read secret data from the CVM or tamper with the code it runs, the security guarantees of the system are broken.
The confidential computing setting turns typical trust assumptions on their heads. Decades of work has gone into protecting host boxes from malicious VMs, but very few Linux utilities are designed to protect a VM from a malicious host. The issue described in this post is just one trap in a broader minefield of unsafe patterns that CVM-based systems must navigate. If your team is building a confidential computing solution and is concerned about unknown footguns, we are happy to offer a free office hours call with one of our engineers.
The LUKS2 on-disk format
A disk using the LUKS2 encryption format starts with a header, followed by the actual encrypted data. The header contains two identical copies of binary and JSON-formatted metadata sections, followed by some number of keyslots.
Figure 1: LUKS2 on-disk encryption format
Each keyslot contains a copy of the volume key, encrypted with a single user password or token. The JSON metadata section defines which keyslots are enabled, what cipher is used to unlock each keyslot, and what cipher is used for the encrypted data segments.
Here is a typical JSON metadata object for a disk with a single keyslot. The keyslot uses Argon2id and AES-XTS to encrypt the volume key under a user password. The segment object defines the cipher used to encrypt the data volume. The digest object stores a hash of the volume key, which cryptsetup uses to check whether the correct passphrase was provided.
Figure 2: Example JSON metadata object for a disk with a single keyslot
LUKS, ma—No keys
By default, LUKS2 uses AES-XTS encryption, a standard mode for size-preserving encryption. What other modes might be supported? As of cryptsetup version 2.8.0, the following header would be accepted.
Figure 3: Acceptable header with encryption set to cipher_null-ecb
The cipher_null-ecb algorithm does nothing. It ignores its key and returns data unchanged. In particular, it simply ignores its key and acts as the identity function on the data. Any attacker can change the cipher, fiddle with some digests, and hand the resulting disk to an unsuspecting CVM; the CVM will then use the disk as if it were securely encrypted, reading configuration data from and writing secrets to the completely unencrypted volume.
When a null cipher is used to encrypt a keyslot, that keyslot can be successfully opened with any passphrase. In this case, the attacker does not need any information about the CVM’s encryption keys to produce a malicious disk.
We disclosed this issue to the cryptsetup maintainers, who warned that LUKS is not intended to provide integrity in this setting and asserted that the presence of null ciphers is important for backward compatibility. In cryptsetup 2.8.1 and higher, null ciphers are now rejected as keyslot ciphers when used with a nonempty password.
Null ciphers remain in cryptsetup 2.8.1 as a valid option for volume keys. In order to exploit this weakness, an attacker simply needs to observe the header from some encrypted disk formatted using the target CVM’s passphrase. When the volume encryption is set to cipher_null-ecb and the keyslot cipher is left untouched, a CVM will be able to unlock the keyslot using its passphrase and start using the unencrypted volume without error.
Validating LUKS metadata
For any confidential computing application, it is imperative to fully validate the LUKS header before use. Luckily, cryptsetup provides a detached-header mode, which allows the disk header to be read from a tmpfs file rather than the untrusted disk, as in this example:
cryptsetup open --header /tmp/luks_header /dev/vdb
Use of detached-header mode is critical in all remediation options, in order to prevent time-of-check to time-of-use attacks.
Beyond the issue with null ciphers, LUKS metadata processing is a complex and potentially dangerous process. For example, CVE-2021-4122 used a similar issue to silently decrypt the whole disk as part of an automatic recovery process.
There are three potential ways to validate the header, once it resides in protected memory.
Use a MAC to ensure that the header has not been modified after initial creation.
Validate the header parameters to ensure only secure values are used.
Include the header as a measurement in TPM or remote KMS attestations.
We recommend the first option where possible; by computing a MAC over the full header, applications can be sure that the header is entirely unmodified by malicious actors. See Flashbots’ implementation of this fix in tdx-init as an example of the technique.
If backward compatibility is required, applications may parse the JSON metadata section and validate all relevant fields, as in this example:
#!/bin/bash
set -e
# Store header in confidential RAM fscryptsetup luksHeaderBackup --header-backup-file /tmp/luks_header $BLOCK_DEVICE;# Dump JSON metadata header to a filecryptsetup luksDump --type luks2 --dump-json-metadata /tmp/luks_header > header.json
# Validate the headerpython validate.py header.json
# Open the cryptfs using key.txtcryptsetup open --type luks2 --header /tmp/luks_header $BLOCK_DEVICE --key-file=key.txt
Finally, one may measure the header data, with any random salts and digests removed, into the attestation state. This measurement is incorporated into any TPM sealing PCRs or attestations sent to a KMS. In this model, LUKS header configuration becomes part of the CVM identity and allows remote verifiers to set arbitrary policies with respect to what configurations are allowed to receive decryption keys.

The comfort zone in cybersecurity is gone. Attackers are scaling down, focusing tighter, and squeezing more value from fewer, high-impact targets. At the same time, defenders face growing blind spots — from spoofed messages to large-scale social engineering.

Ultimately, the architects settled on a creative solution. Rather than bolt KEM onto the existing double ratchet, they allowed it to remain more or less the same as it had been. Then they used the new quantum-safe ratchet to implement a parallel secure messaging system.
Now, when the protocol encrypts a message, it sources encryption keys from both the classic Double Ratchet and the new ratchet. It then mixes the two keys together (using a cryptographic key derivation function) to get a new encryption key that has all of the security of the classical Double Ratchet but now has quantum security, too...
One year from now, with the release of Chrome 154 in October 2026, we will change the default settings of Chrome to enable “Always Use Secure Connections”. This means Chrome will ask for the user's permission before the first access to any public site without HTTPS.
The “Always Use Secure Connections” setting warns users before accessing a site without HTTPS
Chrome Security's mission is to make it safe to click on links. Part of being safe means ensuring that when a user types a URL or clicks on a link, the browser ends up where the user intended. When links don't use HTTPS, an attacker can hijack the navigation and force Chrome users to load arbitrary, attacker-controlled resources, and expose the user to malware, targeted exploitation, or social engineering attacks. Attacks like this are not hypothetical—software to hijack navigations is readily available and attackers have previously used insecure HTTP to compromise user devices in a targeted attack.
Since attackers only need a single insecure navigation, they don't need to worry that many sites have adopted HTTPS—any single HTTP navigation may offer a foothold. What's worse, many plaintext HTTP connections today are entirely invisible to users, as HTTP sites may immediately redirect to HTTPS sites. That gives users no opportunity to see Chrome's "Not Secure" URL bar warnings after the risk has occurred, and no opportunity to keep themselves safe in the first place.
To address this risk, we launched the “Always Use Secure Connections” setting in 2022 as an opt-in option. In this mode, Chrome attempts every connection over HTTPS, and shows a bypassable warning to the user if HTTPS is unavailable. We also previously discussed our intent to move towards HTTPS by default. We now think the time has come to enable “Always Use Secure Connections” for all users by default.
Now is the time.
For more than a decade, Google has published the HTTPS transparency report, which tracks the percentage of navigations in Chrome that use HTTPS. For the first several years of the report, numbers saw an impressive climb, starting at around 30-45% in 2015, and ending up around the 95-99% range around 2020. Since then, progress has largely plateaued.
HTTPS adoption expressed as a percentage of main frame page loads
This rise represents a tremendous improvement to the security of the web, and demonstrates that HTTPS is now mature and widespread. This level of adoption is what makes it possible to consider stronger mitigations against the remaining insecure HTTP.
Balancing user safety with friction
While it may at first seem that 95% HTTPS means that the problem is mostly solved, the truth is that a few percentage points of HTTP navigations is still a lot of navigations. Since HTTP navigations remain a regular occurrence for most Chrome users, a naive approach to warning on all HTTP navigations would be quite disruptive. At the same time, as the plateau demonstrates, doing nothing would allow this risk to persist indefinitely. To balance these risks, we have taken steps to ensure that we can help the web move towards safer defaults, while limiting the potential annoyance warnings will cause to users.
One way we're balancing risks to users is by making sure Chrome does not warn about the same sites excessively. In all variants of the "Always Use Secure Connections" settings, so long as the user regularly visits an insecure site, Chrome will not warn the user about that site repeatedly. This means that rather than warn users about 1 out of 50 navigations, Chrome will only warn users when they visit a new (or not recently visited) site without using HTTPS.
To further address the issue, it's important to understand what sort of traffic is still using HTTP. The largest contributor to insecure HTTP by far, and the largest contributor to variation across platforms, is insecure navigations to private sites. The graph above includes both those to public sites, such as example.com, and navigations to private sites, such as local IP addresses like 192.168.0.1, single-label hostnames, and shortlinks like intranet/. While it is free and easy to get an HTTPS certificate that is trusted by Chrome for a public site, acquiring an HTTPS certificate for a private site unfortunately remains complicated. This is because private names are "non-unique"—private names can refer to different hosts on different networks. There is no single owner of 192.168.0.1 for a certification authority to validate and issue a certificate to.
HTTP navigations to private sites can still be risky, but are typically less dangerous than their public site counterparts because there are fewer ways for an attacker to take advantage of these HTTP navigations. HTTP on private sites can only be abused by an attacker also on your local network, like on your home wifi or in a corporate network.
If you exclude navigations to private sites, then the distribution becomes much tighter across platforms. In particular, Linux jumps from 84% HTTPS to nearly 97% HTTPS when limiting the analysis to public sites only. Windows increases from 95% to 98% HTTPS, and both Android and Mac increase to over 99% HTTPS.
In recognition of the reduced risk HTTP to private sites represents, last year we introduced a variant of “Always Use Secure Connections” for public sites only. For users who frequently access private sites (such as those in enterprise settings, or web developers), excluding warnings on private sites significantly reduces the volume of warnings those users will see. Simultaneously, for users who do not access private sites frequently, this mode introduces only a small reduction in protection. This is the variant we intend to enable for all users next year.
“Always Use Secure Connections,” available at chrome://settings/security
In Chrome 141, we experimented with enabling “Always Use Secure Connections” for public sites by default for a small percentage of users. We wanted to validate our expectations that this setting keeps users safer without burdening them with excessive warnings.
Analyzing the data from the experiment, we confirmed that the number of warnings seen by any users is considerably lower than 3% of navigations—in fact, the median user sees fewer than one warning per week, and the ninety-fifth percentile user sees fewer than three warnings per week..
Understanding HTTP usage
Once “Always Use Secure Connections” is the default and additional sites migrate away from HTTP, we expect the actual warning volume to be even lower than it is now. In parallel to our experiments, we have reached out to a number of companies responsible for the most HTTP navigations, and expect that they will be able to migrate away from HTTP before the change in Chrome 154. For many of these organizations, transitioning to HTTPS isn't disproportionately hard, but simply has not received attention. For example, many of these sites use HTTP only for navigations that immediately redirect to HTTPS sites—an insecure interaction which was previously completely invisible to users.
Another current use case for HTTP is to avoid mixed content blocking when accessing devices on the local network. Private addresses, as discussed above, often do not have trusted HTTPS certificates, due to the difficulties of validating ownership of a non-unique name. This means most local network traffic is over HTTP, and cannot be initiated from an HTTPS page—the HTTP traffic counts as insecure mixed content, and is blocked. One common use case for needing to access the local network is to configure a local network device, e.g. the manufacturer might host a configuration portal at config.example.com, which then sends requests to a local device to configure it.
Previously, these types of pages needed to be hosted without HTTPS to avoid mixed content blocking. However, we recently introduced a local network access permission, which both prevents sites from accessing the user’s local network without consent, but also allows an HTTPS site to bypass mixed content checks for the local network once the permission has been granted. This can unblock migrating these domains to HTTPS.
Changes in Chrome
We will enable the "Always Use Secure Connections" setting in its public-sites variant by default in October 2026, with the release of Chrome 154. Prior to enabling it by default for all users, in Chrome 147, releasing in April 2026, we will enable Always Use Secure Connections in its public-sites variant for the over 1 billion users who have opted-in to Enhanced Safe Browsing protections in Chrome.
While it is our hope and expectation that this transition will be relatively painless for most users, users will still be able to disable the warnings by disabling the "Always Use Secure Connections" setting.
If you are a website developer or IT professional, and you have users who may be impacted by this feature, we very strongly recommend enabling the "Always Use Secure Connections" setting today to help identify sites that you may need to work to migrate. IT professionals may find it useful to read our additional resources to better understand the circumstances where warnings will be shown, how to mitigate them, and how organizations that manage Chrome clients (like enterprises or educational institutions) can ensure that Chrome shows the right warnings to meet those organizations' needs.
Looking Forward
While we believe that warning on insecure public sites represents a significant step forward for the security of the web, there is still more work to be done. In the future, we hope to work to further reduce barriers to adoption of HTTPS, especially for local network sites. This work will hopefully enable even more robust HTTP protections down the road.

As Cybersecurity Awareness Month wraps up, we’re focusing on one of today’s most pervasive digital threats: mobile scams. In the last 12 months, fraudsters have used advanced AI tools to create more convincing schemes, resulting in over $400 billion in stolen funds globally.¹
For years, Android has been on the frontlines in the battle against scammers, using the best of Google AI to build proactive, multi-layered protections that can anticipate and block scams before they reach you. Android’s scam defenses protect users around the world from over 10 billion suspected malicious calls and messages every month2. In addition, Google continuously performs safety checks to maintain the integrity of the RCS service. In the past month alone, this ongoing process blocked over 100 million suspicious numbers from using RCS, stopping potential scams before they could even be sent.
To show how our scam protections work in the real world, we asked users and independent security experts to compare how well Android and iOS protect you from these threats. We're also releasing a new report that explains how modern text scams are orchestrated, helping you understand the tactics fraudsters use and how to spot them.
Survey shows Android users’ confidence in scam protections
Google and YouGov3 surveyed 5,000 smartphone users across the U.S., India, and Brazil about their experiences. The findings were clear: Android users reported receiving fewer scam texts and felt more confident that their device was keeping them safe.
Android users were 58% more likely than iOS users to say they had not received any scam texts in the week prior to the survey. The advantage was even stronger on Pixel, where users were 96% more likely than iPhone owners to report zero scam texts.
At the other end of the spectrum, iOS users were 65% more likely than Android users to report receiving three or more scam texts in a week. The difference became even more pronounced when comparing iPhone to Pixel, with iPhone users 136% more likely to say they had received a heavy volume of scam messages.
Android users were 20% more likely than iOS users to describe their device’s scam protections as “very effective” or “extremely effective.” When comparing Pixel to iPhone, iPhone users were 150% more likely to say their device was not effective at all in stopping mobile fraud.
YouGov study findings on users’ experience with scams on Android and iOS
Security researchers and analysts highlight Android’s AI-driven safeguards against sophisticated scams
In a recent evaluation by Counterpoint Research4, a global technology market research firm, Android smartphones were found to have the most AI-powered protections. The independent study compared the latest Pixel, Samsung, Motorola, and iPhone devices, and found that Android provides comprehensive AI-driven safeguards across ten key protection areas, including email protections, browsing protections, and on-device behavioral protections. By contrast, iOS offered AI-powered protections in only two categories. You can see the full comparison in the visual below.
Counterpoint Research comparison of Android and iOS AI-powered protections
Cybersecurity firm Leviathan Security Group conducted a funded evaluation5 of scam and fraud protection on the iPhone 17, Moto Razr+ 2025, Pixel 10 Pro, and Samsung Galaxy Z Fold 7. Their analysis found that Android smartphones, led by the Pixel 10 Pro, provide the highest level of default scam and fraud protection.The report particularly noted Android's robust call screening, scam detection, and real-time scam warning authentication capabilities as key differentiators. Taken together, these independent expert assessments conclude that Android’s AI-driven safeguards provide more comprehensive and intelligent protection against mobile scams.
Leviathan Security Group comparison of scam protections across various devices
Why Android users see fewer scams
Android’s proactive protections work across the platform to help you stay ahead of threats with the best of Google AI.
Here’s how they work:
Keeping your messages safe: Google Messages automatically filters known spam by analyzing sender reputation and message content, moving suspicious texts directly to your "spam & blocked" folder to keep them out of sight. For more complex threats, Scam Detection uses on-device AI to analyze messages from unknown senders for patterns of conversational scams (like pig butchering) and provide real-time warnings6. This helps secure your privacy while providing a robust shield against text scams. As an extra safeguard, Google Messages also helps block suspicious links in messages that are determined to be spam or scams.
Combatting phone call scams:Phone by Google automatically blocks known spam calls so your phone never even rings, while Call Screen5 can answer the call on your behalf to identify fraudsters. If you answer, the protection continues with Scam Detection, which uses on-device AI to provide real-time warnings for suspicious conversational patterns6. This processing is completely ephemeral, meaning no call content is ever saved or leaves your device. Android also helps stop social engineering during the call itself by blocking high-risk actions6like installing untrusted apps or disabling security settings, and warns you if your screen is being shared unknowingly.
These safeguards are built directly into the core of Android, alongside other features like real-time app scanning in Google Play Protect and enhanced Safe Browsing in Chrome using LLMs. With Android, you can trust that you have intelligent, multi-layered protection against scams working for you.
Android is always evolving to keep you one step ahead of scams
In a world of evolving digital threats, you deserve to feel confident that your phone is keeping you safe. That’s why we use the best of Google AI to build intelligent protections that are always improving and work for you around the clock, so you can connect, browse, and communicate with peace of mind.

Interesting article about the arms race between AI systems that invent/design new biological pathogens, and AI systems that detect them before they’re created:
The team started with a basic test: use AI tools to design variants of the toxin ricin, then test them against the software that is used to screen DNA orders. The results of the test suggested there was a risk of dangerous protein variants slipping past existing screening software, so the situation was treated like the equivalent of a zero-day vulnerability.
Trail of Bits is disclosing vulnerabilities in eight different confidential computing systems that use Linux Unified Key Setup version 2 (LUKS2) for disk encryption. Using these vulnerabilities, a malicious actor with access to storage disks can extract all confidential data stored on that disk and can modify the contents of the disk arbitrarily. The vulnerabilities are caused by malleable metadata headers that allow an attacker to trick a trusted execution environment guest into encrypting secret data with a null cipher.
The following CVEs are associated with this disclosure:
We also notified the Confidential Containers project, who indicated that the relevant code, part of the guest-components repository, is not currently used in production.
Users of these confidential computing frameworks should update to the latest version. Consumers of remote attestation reports should disallow pre-patch versions in attestation reports.
Exploitation of this issue requires write access to encrypted disks. We do not have any indication that this issue has been exploited in the wild.
These systems all use trusted execution environments such as AMD SEV-SNP and Intel TDX to protect a confidential Linux VM from a potentially malicious host. Each relies on LUKS2 to protect disk volumes used to hold the VM’s persistent state. LUKS2 is a disk encryption format originally designed for at-rest encryption of PC and server hard disks. We found that LUKS is not always secure in settings where the disk is subject to modifications by an attacker.
Confidential VMs
The affected systems are Linux-based confidential virtual machines (CVMs). These are not interactive Linux boxes with user logins; they are specialized automated systems designed to handle secrets while running in an untrusted environment. Typical use cases are private AI inference, private blockchains, or multi-party data collaboration. Such a system should satisfy the following requirements:
Confidentiality: The host OS should not be able to read memory or data inside the CVM.
Integrity: The host OS should not be able to interfere with the logical operation of the CVM.
Authenticity: A remote party should be able to verify that they are interacting with a genuine CVM running the expected program.
Remote users verify the authenticity of a CVM via a remote attestation process, in which the secure hardware generates a “quote” signed by a secret key provisioned by the hardware manufacturer. This quote contains measurements of the CVM configuration and code. If an attacker with access to the host machine can read secret data from the CVM or tamper with the code it runs, the security guarantees of the system are broken.
The confidential computing setting turns typical trust assumptions on their heads. Decades of work has gone into protecting host boxes from malicious VMs, but very few Linux utilities are designed to protect a VM from a malicious host. The issue described in this post is just one trap in a broader minefield of unsafe patterns that CVM-based systems must navigate. If your team is building a confidential computing solution and is concerned about unknown footguns, we are happy to offer a free office hours call with one of our engineers.
The LUKS2 on-disk format
A disk using the LUKS2 encryption format starts with a header, followed by the actual encrypted data. The header contains two identical copies of binary and JSON-formatted metadata sections, followed by some number of keyslots.
Figure 1: LUKS2 on-disk encryption format
Each keyslot contains a copy of the volume key, encrypted with a single user password or token. The JSON metadata section defines which keyslots are enabled, what cipher is used to unlock each keyslot, and what cipher is used for the encrypted data segments.
Here is a typical JSON metadata object for a disk with a single keyslot. The keyslot uses Argon2id and AES-XTS to encrypt the volume key under a user password. The segment object defines the cipher used to encrypt the data volume. The digest object stores a hash of the volume key, which cryptsetup uses to check whether the correct passphrase was provided.
Figure 2: Example JSON metadata object for a disk with a single keyslot
LUKS, ma—No keys
By default, LUKS2 uses AES-XTS encryption, a standard mode for size-preserving encryption. What other modes might be supported? As of cryptsetup version 2.8.0, the following header would be accepted.
Figure 3: Acceptable header with encryption set to cipher_null-ecb
The cipher_null-ecb algorithm does nothing. It ignores its key and returns data unchanged. In particular, it simply ignores its key and acts as the identity function on the data. Any attacker can change the cipher, fiddle with some digests, and hand the resulting disk to an unsuspecting CVM; the CVM will then use the disk as if it were securely encrypted, reading configuration data from and writing secrets to the completely unencrypted volume.
When a null cipher is used to encrypt a keyslot, that keyslot can be successfully opened with any passphrase. In this case, the attacker does not need any information about the CVM’s encryption keys to produce a malicious disk.
We disclosed this issue to the cryptsetup maintainers, who warned that LUKS is not intended to provide integrity in this setting and asserted that the presence of null ciphers is important for backward compatibility. In cryptsetup 2.8.1 and higher, null ciphers are now rejected as keyslot ciphers when used with a nonempty password.
Null ciphers remain in cryptsetup 2.8.1 as a valid option for volume keys. In order to exploit this weakness, an attacker simply needs to observe the header from some encrypted disk formatted using the target CVM’s passphrase. When the volume encryption is set to cipher_null-ecb and the keyslot cipher is left untouched, a CVM will be able to unlock the keyslot using its passphrase and start using the unencrypted volume without error.
Validating LUKS metadata
For any confidential computing application, it is imperative to fully validate the LUKS header before use. Luckily, cryptsetup provides a detached-header mode, which allows the disk header to be read from a tmpfs file rather than the untrusted disk, as in this example:
cryptsetup open --header /tmp/luks_header /dev/vdb
Use of detached-header mode is critical in all remediation options, in order to prevent time-of-check to time-of-use attacks.
Beyond the issue with null ciphers, LUKS metadata processing is a complex and potentially dangerous process. For example, CVE-2021-4122 used a similar issue to silently decrypt the whole disk as part of an automatic recovery process.
There are three potential ways to validate the header, once it resides in protected memory.
Use a MAC to ensure that the header has not been modified after initial creation.
Validate the header parameters to ensure only secure values are used.
Include the header as a measurement in TPM or remote KMS attestations.
We recommend the first option where possible; by computing a MAC over the full header, applications can be sure that the header is entirely unmodified by malicious actors. See Flashbots’ implementation of this fix in tdx-init as an example of the technique.
If backward compatibility is required, applications may parse the JSON metadata section and validate all relevant fields, as in this example:
#!/bin/bash
set -e
# Store header in confidential RAM fscryptsetup luksHeaderBackup --header-backup-file /tmp/luks_header $BLOCK_DEVICE;# Dump JSON metadata header to a filecryptsetup luksDump --type luks2 --dump-json-metadata /tmp/luks_header > header.json
# Validate the headerpython validate.py header.json
# Open the cryptfs using key.txtcryptsetup open --type luks2 --header /tmp/luks_header $BLOCK_DEVICE --key-file=key.txt
Finally, one may measure the header data, with any random salts and digests removed, into the attestation state. This measurement is incorporated into any TPM sealing PCRs or attestations sent to a KMS. In this model, LUKS header configuration becomes part of the CVM identity and allows remote verifiers to set arbitrary policies with respect to what configurations are allowed to receive decryption keys.

For the first several years of the report, numbers saw an impressive climb, starting at around 30-45% in 2015, and ending up around the 95-99% range around 2020. Since then, progress has largely plateaued.
HTTPS adoption expressed as a percentage of main frame page loads
This rise represents a tremendous improvement to the security of the web, and demonstrates that HTTPS is now mature and widespread. This level of adoption is what makes it possible to consider stronger mitigations against the remaining insecure HTTP.
Balancing user safety with friction
While it may at first seem that 95% HTTPS means that the problem is mostly solved, the truth is that a few percentage points of HTTP navigations is still a lot of navigations. Since HTTP navigations remain a regular occurrence for most Chrome users, a naive approach to warning on all HTTP navigations would be quite disruptive. At the same time, as the plateau demonstrates, doing nothing would allow this risk to persist indefinitely. To balance these risks, we have taken steps to ensure that we can help the web move towards safer defaults, while limiting the potential annoyance warnings will cause to users.
One way we're balancing risks to users is by making sure Chrome does not warn about the same sites excessively. In all variants of the "Always Use Secure Connections" settings, so long as the user regularly visits an insecure site, Chrome will not warn the user about that site repeatedly. This means that rather than warn users about 1 out of 50 navigations, Chrome will only warn users when they visit a new (or not recently visited) site without using HTTPS.
To further address the issue, it's important to understand what sort of traffic is still using HTTP. The largest contributor to insecure HTTP by far, and the largest contributor to variation across platforms, is insecure navigations to private sites. The graph above includes both those to public sites, such as example.com, and navigations to private sites, such as local IP addresses like 192.168.0.1, single-label hostnames, and shortlinks like intranet/. While it is free and easy to get an HTTPS certificate that is trusted by Chrome for a public site, acquiring an HTTPS certificate for a private site unfortunately remains complicated. This is because private names are "non-unique"—private names can refer to different hosts on different networks. There is no single owner of 192.168.0.1 for a certification authority to validate and issue a certificate to.
HTTP navigations to private sites can still be risky, but are typically less dangerous than their public site counterparts because there are fewer ways for an attacker to take advantage of these HTTP navigations. HTTP on private sites can only be abused by an attacker also on your local network, like on your home wifi or in a corporate network.
If you exclude navigations to private sites, then the distribution becomes much tighter across platforms. In particular, Linux jumps from 84% HTTPS to nearly 97% HTTPS when limiting the analysis to public sites only. Windows increases from 95% to 98% HTTPS, and both Android and Mac increase to over 99% HTTPS.
In recognition of the reduced risk HTTP to private sites represents, last year we introduced a variant of “Always Use Secure Connections” for public sites only. For users who frequently access private sites (such as those in enterprise settings, or web developers), excluding warnings on private sites significantly reduces the volume of warnings those users will see. Simultaneously, for users who do not access private sites frequently, this mode introduces only a small reduction in protection. This is the variant we intend to enable for all users next year.
“Always Use Secure Connections,” available at chrome://settings/security
In Chrome 141, we experimented with enabling “Always Use Secure Connections” for public sites by default for a small percentage of users. We wanted to validate our expectations that this setting keeps users safer without burdening them with excessive warnings.
Analyzing the data from the experiment, we confirmed that the number of warnings seen by any users is considerably lower than 3% of navigations—in fact, the median user sees fewer than one warning per week, and the ninety-fifth percentile user sees fewer than three warnings per week..
Understanding HTTP usage
Once “Always Use Secure Connections” is the default and additional sites migrate away from HTTP, we expect the actual warning volume to be even lower than it is now. In parallel to our experiments, we have reached out to a number of companies responsible for the most HTTP navigations, and expect that they will be able to migrate away from HTTP before the change in Chrome 154. For many of these organizations, transitioning to HTTPS isn't disproportionately hard, but simply has not received attention. For example, many of these sites use HTTP only for navigations that immediately redirect to HTTPS sites—an insecure interaction which was previously completely invisible to users.
Another current use case for HTTP is to avoid mixed content blocking when accessing devices on the local network. Private addresses, as discussed above, often do not have trusted HTTPS certificates, due to the difficulties of validating ownership of a non-unique name. This means most local network traffic is over HTTP, and cannot be initiated from an HTTPS page—the HTTP traffic counts as insecure mixed content, and is blocked. One common use case for needing to access the local network is to configure a local network device, e.g. the manufacturer might host a configuration portal at config.example.com, which then sends requests to a local device to configure it.
Previously, these types of pages needed to be hosted without HTTPS to avoid mixed content blocking. However, we recently introduced a local network access permission, which both prevents sites from accessing the user’s local network without consent, but also allows an HTTPS site to bypass mixed content checks for the local network once the permission has been granted. This can unblock migrating these domains to HTTPS.
Changes in Chrome
We will enable the "Always Use Secure Connections" setting in its public-sites variant by default in October 2026, with the release of Chrome 154. Prior to enabling it by default for all users, in Chrome 147, releasing in April 2026, we will enable Always Use Secure Connections in its public-sites variant for the over 1 billion users who have opted-in to Enhanced Safe Browsing protections in Chrome.
While it is our hope and expectation that this transition will be relatively painless for most users, users will still be able to disable the warnings by disabling the "Always Use Secure Connections" setting.
If you are a website developer or IT professional, and you have users who may be impacted by this feature, we very strongly recommend enabling the "Always Use Secure Connections" setting today to help identify sites that you may need to work to migrate. IT professionals may find it useful to read our additional resources to better understand the circumstances where warnings will be shown, how to mitigate them, and how organizations that manage Chrome clients (like enterprises or educational institutions) can ensure that Chrome shows the right warnings to meet those organizations' needs.
Looking Forward
While we believe that warning on insecure public sites represents a significant step forward for the security of the web, there is still more work to be done. In the future, we hope to work to further reduce barriers to adoption of HTTPS, especially for local network sites. This work will hopefully enable even more robust HTTP protections down the road.

Today we’re announcing the next major chapter for Apple Security Bounty, featuring the industry’s highest rewards, expanded research categories, and a flag system for researchers to objectively demonstrate vulnerabilities and obtain accelerated awards.
We’re doubling our top award to $2 million for exploit chains that can achieve similar goals as sophisticated mercenary spyware attacks. This is an unprecedented amount in the industry and the largest payout offered by any bounty program we’re aware of and our bonus system, providing additional rewards for Lockdown Mode bypasses and vulnerabilities discovered in beta software, can more than double this reward, with a maximum payout in excess of $5 million. We’re also doubling or significantly increasing rewards in many other categories to encourage more intensive research. This includes $100,000 for a complete Gatekeeper bypass, and $1 million for broad unauthorized iCloud access, as no successful exploit has been demonstrated to date in either category.

A retired veteran named Lee Schmidt wanted to know how often Norfolk, Virginia’s 176 Flock Safety automated license-plate-reader cameras were tracking him. The answer, according to a U.S. District Court lawsuit filed in September, was more than four times a day, or 526 times from mid-February to early July. No, there’s no warrant out for Schmidt’s arrest, nor is there a warrant for Schmidt’s co-plaintiff, Crystal Arrington, whom the system tagged 849 times in roughly the same period.

The widespread fear that AI would be used to manipulate the 2024 U.S. election seems rather quaint in a year where the president posts AI-generated images of himself as the pope on official White House accounts. But AI is a lot more than an information manipulator. It’s also emerging as a politicized issue. Political first-movers are adopting the technology, and that’s opening a ...
A now patched security vulnerability in Zimbra Collaboration was exploited as a zero-day earlier this year in cyber attacks targeting the Brazilian military.
Tracked as CVE-2025-27915 (CVSS score: 5.4), the vulnerability is a stored cross-site scripting (XSS) vulnerability in the Classic Web Client that arises as a result of insufficient sanitization of HTML content in ICS calendar files,

This primer maps what we currently know about generative AI’s role in scams, the communities most at risk, and the broader economic and cultural shifts that are making people more willing to take risks, more vulnerable to deception, and more likely to either perpetuate scams or fall victim to them.
AI-enhanced scams are not merely financial or technological crimes; they also exploit social vulnerabilities whether short-term, like travel, or structural, like precarious employment. This means they require social solutions in addition to technical ones. By examining how scammers are changing and accelerating their methods, we hope to show that defending against them will require a constellation of cultural shifts, corporate interventions, and effective legislation...

Empowering cyber defenders with AI is critical to tilting the cybersecurity balance back in their favor as they battle cybercriminals and keep users safe. To help accelerate adoption of AI for cybersecurity workflows, we partnered with Airbus at DEF CON 33 to host the GenSec Capture the Flag (CTF), dedicated to human-AI collaboration in cybersecurity. Our goal was to create a fun, interactive environment, where participants across various skill levels could explore how AI can accelerate their daily cybersecurity workflows.
At GenSec CTF, nearly 500 participants successfully completed introductory challenges, with 23% of participants using AI for cybersecurity for the very first time. An overwhelming 85% of all participants found the event useful for learning how AI can be applied to security workflows. This positive feedback highlights that AI-centric CTFs can play a vital role in speeding up AI education and adoption in the security community.
The CTF also offered a valuable opportunity for the community to use Sec-Gemini, Google’s experimental Cybersecurity AI, as an optional assistant available in the UI alongside major LLMs. And we received great feedback on Sec-Gemini, with 77% of respondents saying that they had found Sec-Gemini either “very helpful” or “extremely helpful” in assisting them with solving the challenges.
We want to thank the DEF CON community for the enthusiastic participation and for making this inaugural event a resounding success. The community feedback during the event has been invaluable for understanding how to improve Sec-Gemini, and we are already incorporating some of the lessons learned into the next iteration.
We are committed to advancing the AI cybersecurity frontier and will continue working with the community to build tools that help protect people online. Stay tuned as we plan to share more research and key learnings from the CTF with the broader community.

Apple has introduced a new hardware/software security feature in the iPhone 17: “Memory Integrity Enforcement,” targeting the memory safety vulnerabilities that spyware products like Pegasus tend to use to get unauthorized system access. From Wired:
In recent years, a movement has been steadily growing across the global tech industry to address a ubiquitous and insidious type of bugs known as memory-safety vulnerabilities. A computer’s memory is a shared resource among all programs, and memory safety issues crop up when software can pull data that should be off limits from a computer’s memory or manipulate data in memory that shouldn’t be accessible to the program. When developers—even experienced and security-conscious developers—write software in ubiquitous, historic programming languages, like C and C++, it’s easy to make mistakes that lead to memory safety vulnerabilities. That’s why proactive tools like ...

Abstract: Large Language Model (LLM)-enabled agents are rapidly emerging across a wide range of applications, but their deployment introduces vulnerabilities with security implications. While prior work has examined prompt-based attacks (e.g., prompt injection) and data-oriented threats (e.g., data exfiltration), time-of-check to time-of-use (TOCTOU) remain largely unexplored in this context. TOCTOU arises when an agent validates external state (e.g., a file or API response) that is later modified before use, enabling practical attacks such as malicious configuration swaps or payload injection. In this work, we present the first study of TOCTOU vulnerabilities in LLM-enabled agents. We introduce TOCTOU-Bench, a benchmark with 66 realistic user tasks designed to evaluate this class of vulnerabilities. As countermeasures, we adapt detection and mitigation techniques from systems security to this setting and propose prompt rewriting, state integrity monitoring, and tool-fusing. Our study highlights challenges unique to agentic workflows, where we achieve up to 25% detection accuracy using automated detection methods, a 3% decrease in vulnerable plan generation, and a 95% reduction in the attack window. When combining all three approaches, we reduce the TOCTOU vulnerabilities from an executed trajectory from 12% to 8%.

Fifteen years after its debut, Zero Trust remains the gold standard in cybersecurity theory — but its uneven implementation leaves organizations both stronger and dangerously exposed.
Rowhammer is a complex class of vulnerabilities across the industry. It is a hardware vulnerability in DRAM where repeatedly accessing a row of memory can cause bit flips in adjacent rows, leading to data corruption. This can be exploited by attackers to gain unauthorized access to data, escalate privileges, or cause denial of service. Hardware vendors have deployed various mitigations, such as ECC and Target Row Refresh (TRR) for DDR5 memory, to mitigate Rowhammer and enhance DRAM reliability. However, the resilience of those mitigations against sophisticated attackers remains an open question.
To address this gap and help the ecosystem with deploying robust defenses, Google has supported academic research and developed test platforms to analyze DDR5 memory. Our effort has led to the discovery of new attacks and a deeper understanding of Rowhammer on the current DRAM modules, helping to forge the way for further, stronger mitigations.
What is Rowhammer?
Rowhammer exploits a vulnerability in DRAM. DRAM cells store data as electrical charges, but these electric charges leak over time, causing data corruption. To prevent data loss, the memory controller periodically refreshes the cells. However, if a cell discharges before the refresh cycle, its stored bit may corrupt. Initially considered a reliability issue, it has been leveraged by security researchers to demonstrate privilege escalation attacks. By repeatedly accessing a memory row, an attacker can cause bit flips in neighboring rows. An adversary can exploit Rowhammer via:
Reliably cause bit flips by repeatedly accessing adjacent DRAM rows.
Coerce other applications or the OS into using these vulnerable memory pages.
Target security-sensitive code or data to achieve privilege escalation.
Or simply corrupt system’s memory to cause denial of service.
The primary approach to mitigate Rowhammer is to detect which memory rows are being aggressively accessed and refreshing nearby rows before a bit flip occurs. TRR is a common example, which uses a number of counters to track accesses to a small number of rows adjacent to a potential victim row. If the access count for these aggressor rows reaches a certain threshold, the system issues a refresh to the victim row. TRR can be incorporated within the DRAM or in the host CPU.
However, this mitigation is not foolproof. For example, the TRRespass attack showed that by simultaneously hammering multiple, non-adjacent rows, TRR can be bypassed. Over the past couple of years, more sophisticated attacks [Half-Double, Blacksmith] have emerged, introducing more efficient attack patterns.
In response, one of our efforts was to collaborate with JEDEC, external researchers, and experts to define thePRAC as a new mitigation that deterministically detects Rowhammer by tracking all memory rows.
However, current systems equipped with DDR5 lack support for PRAC or other robust mitigations. As a result, they rely on probabilistic approaches such as ECC and enhanced TRRto reduce the risk. While these measures have mitigated older attacks, their overall effectiveness against new techniques was not fully understood until our recent findings.
Challenges with Rowhammer Assessment
Mitigating Rowhammer attacks involves making it difficult for an attacker to reliably cause bit flips from software. Therefore, for an effective mitigation, we have to understand how a determined adversary introduces memory accesses that bypass existing mitigations. Three key information components can help with such an analysis:
How the improved TRR and in-DRAM ECC work.
How memory access patterns from software translate into low-level DDR commands.
(Optionally) How any mitigations (e.g., ECC or TRR) in the host processor work.
The first step is particularly challenging and involves reverse-engineering the proprietary in-DRAM TRR mechanism, which varies significantly between different manufacturers and device models. This process requires the ability to issue precise DDR commands to DRAM and analyze its responses, which is difficult on an off-the-shelf system. Therefore, specialized test platforms are essential.
The second and third steps involve analyzing the DDR traffic between the host processor and the DRAM. This can be done using an off-the-shelf interposer, a tool that sits between the processor and DRAM. A crucial part of this analysis is understanding how a live system translates software-level memory accesses into the DDR protocol.
The third step, which involves analyzing host-side mitigations, is sometimes optional. For example, host-side ECC (Error Correcting Code) is enabled by default on servers, while host-side TRR has only been implemented in some CPUs.
Rowhammer testing platforms
For the first challenge, we partnered with Antmicro to develop two specialized, open-source FPGA-based Rowhammer test platforms. These platforms allow us to conduct in-depth testing on different types of DDR5 modules.
DDR5 RDIMM Platform: A new DDR5 Tester board to meet the hardware requirements of Registered DIMM (RDIMM) memory, common in server computers.
SO-DIMM Platform: A version that supports the standard SO-DIMM pinout compatible with off-the-shelf DDR5 SO-DIMM memory sticks, common in workstations and end-user devices.
Antmicro designed and manufactured these open-source platforms and we worked closely with them, and researchers from ETH Zurich, to test the applicability of these platforms for analyzing off-the-shelf memory modules in RDIMM and SO-DIMM forms.
Antmicro DDR5 RDIMM FPGA test platform in action.
Phoenix Attacks on DDR5
In collaboration with researchers from ETH, we applied the new Rowhammer test platforms to evaluate the effectiveness of current in-DRAM DDR5 mitigations. Our findings, detailed in the recently co-authored “Phoenix” research paper, reveal that we successfully developed custom attack patterns capable of bypassing enhanced TRR (Target Row Refresh) defense on DDR5 memory. We were able to create a novel self-correcting refresh synchronization attack technique, which allowed us to perform the first-ever Rowhammer privilege escalation exploit on a standard, production-grade desktop system equipped with DDR5 memory. While this experiment was conducted on an off-the-shelf workstation equipped with recent AMD Zen processors and SK Hynix DDR5 memory, we continue to investigate the applicability of our findings to other hardware configurations.
Lessons learned
We showed that current mitigations for Rowhammer attacks are not sufficient, and the issue remains a widespread problem across the industry. They do make it more difficult “but not impossible” to carry out attacks, since an attacker needs an in-depth understanding of the specific memory subsystem architecture they wish to target.
Current mitigations based on TRR and ECC rely on probabilistic countermeasures that have insufficient entropy. Once an analyst understands how TRR operates, they can craft specific memory access patterns to bypass it. Furthermore, current ECC schemes were not designed as a security measure and are therefore incapable of reliably detecting errors.
Memory encryption is an alternative countermeasure for Rowhammer. However, our current assessment is that without cryptographic integrity, it offers no valuable defense against Rowhammer. More research is needed to develop viable, practical encryption and integrity solutions.
Path forward
Google has been a leader in JEDEC standardization efforts, for instance with PRAC, a fully approved standard to be supported in upcoming versions of DDR5/LPDDR6. It works by accurately counting the number of times a DRAM wordline is activated and alerts the system if an excessive number of activations is detected. This close coordination between the DRAM and the system gives PRAC a reliable way to address Rowhammer.
In the meantime, we continue to evaluate and improve other countermeasures to ensure our workloads are resilient against Rowhammer. We collaborate with our academic and industry partners to improve analysis techniques and test platforms, and to share our findings with the broader ecosystem.

Over the past couple of years, more sophisticated attacks [Half-Double, Blacksmith] have emerged, introducing more efficient attack patterns.
In response, one of our efforts was to collaborate with JEDEC, external researchers, and experts to define thePRAC as a new mitigation that deterministically detects Rowhammer by tracking all memory rows.
However, current systems equipped with DDR5 lack support for PRAC or other robust mitigations. As a result, they rely on probabilistic approaches such as ECC and enhanced TRRto reduce the risk. While these measures have mitigated older attacks, their overall effectiveness against new techniques was not fully understood until our recent findings.
Challenges with Rowhammer Assessment
Mitigating Rowhammer attacks involves making it difficult for an attacker to reliably cause bit flips from software. Therefore, for an effective mitigation, we have to understand how a determined adversary introduces memory accesses that bypass existing mitigations. Three key information components can help with such an analysis:
How the improved TRR and in-DRAM ECC work.
How memory access patterns from software translate into low-level DDR commands.
(Optionally) How any mitigations (e.g., ECC or TRR) in the host processor work.
The first step is particularly challenging and involves reverse-engineering the proprietary in-DRAM TRR mechanism, which varies significantly between different manufacturers and device models. This process requires the ability to issue precise DDR commands to DRAM and analyze its responses, which is difficult on an off-the-shelf system. Therefore, specialized test platforms are essential.
The second and third steps involve analyzing the DDR traffic between the host processor and the DRAM. This can be done using an off-the-shelf interposer, a tool that sits between the processor and DRAM. A crucial part of this analysis is understanding how a live system translates software-level memory accesses into the DDR protocol.
The third step, which involves analyzing host-side mitigations, is sometimes optional. For example, host-side ECC (Error Correcting Code) is enabled by default on servers, while host-side TRR has only been implemented in some CPUs.
Rowhammer testing platforms
For the first challenge, we partnered with Antmicro to develop two specialized, open-source FPGA-based Rowhammer test platforms. These platforms allow us to conduct in-depth testing on different types of DDR5 modules.
DDR5 RDIMM Platform: A new DDR5 Tester board to meet the hardware requirements of Registered DIMM (RDIMM) memory, common in server computers.
SO-DIMM Platform: A version that supports the standard SO-DIMM pinout compatible with off-the-shelf DDR5 SO-DIMM memory sticks, common in workstations and end-user devices.
Antmicro designed and manufactured these open-source platforms and we worked closely with them, and researchers from ETH Zurich, to test the applicability of these platforms for analyzing off-the-shelf memory modules in RDIMM and SO-DIMM forms.
Antmicro DDR5 RDIMM FPGA test platform in action.
Phoenix Attacks on DDR5
In collaboration with researchers from ETH, we applied the new Rowhammer test platforms to evaluate the effectiveness of current in-DRAM DDR5 mitigations. Our findings, detailed in the recently co-authored “Phoenix” research paper, reveal that we successfully developed custom attack patterns capable of bypassing enhanced TRR (Target Row Refresh) defense on DDR5 memory. We were able to create a novel self-correcting refresh synchronization attack technique, which allowed us to perform the first-ever Rowhammer privilege escalation exploit on a standard, production-grade desktop system equipped with DDR5 memory. While this experiment was conducted on an off-the-shelf workstation equipped with recent AMD Zen processors and SK Hynix DDR5 memory, we continue to investigate the applicability of our findings to other hardware configurations.
Lessons learned
We showed that current mitigations for Rowhammer attacks are not sufficient, and the issue remains a widespread problem across the industry. They do make it more difficult “but not impossible” to carry out attacks, since an attacker needs an in-depth understanding of the specific memory subsystem architecture they wish to target.
Current mitigations based on TRR and ECC rely on probabilistic countermeasures that have insufficient entropy. Once an analyst understands how TRR operates, they can craft specific memory access patterns to bypass it. Furthermore, current ECC schemes were not designed as a security measure and are therefore incapable of reliably detecting errors.
Memory encryption is an alternative countermeasure for Rowhammer. However, our current assessment is that without cryptographic integrity, it offers no valuable defense against Rowhammer. More research is needed to develop viable, practical encryption and integrity solutions.
Path forward
Google has been a leader in JEDEC standardization efforts, for instance with PRAC, a fully approved standard to be supported in upcoming versions of DDR5/LPDDR6. It works by accurately counting the number of times a DRAM wordline is activated and alerts the system if an excessive number of activations is detected. This close coordination between the DRAM and the system gives PRAC a reliable way to address Rowhammer.
In the meantime, we continue to evaluate and improve other countermeasures to ensure our workloads are resilient against Rowhammer. We collaborate with our academic and industry partners to improve analysis techniques and test platforms, and to share our findings with the broader ecosystem.

At Made by Google 2025, we announced that the new Google Pixel 10 phones will support C2PA Content Credentials in Pixel Camera and Google Photos. This announcement represents a series of steps towards greater digital media transparency:
The Pixel 10 lineup is the first to have Content Credentials built inacross every photo created by Pixel Camera.
The Pixel Camera app achieved Assurance Level 2, the highest security rating currently defined by the C2PA Conformance Program. Assurance Level 2 for a mobile app is currently only possible on the Android platform.
A private-by-design approach to C2PA certificate management, where no image or group of images can be related to one another or the person who created them.
Pixel 10 phones support on-device trusted time-stamps, which ensures images captured with your native camera app can be trusted after the certificate expires, even if they were captured when your device was offline.
These capabilities are powered by Google Tensor G5, Titan M2 security chip, the advanced hardware-backed security features of the Android platform, and Pixel engineering expertise.
In this post, we’ll break down our architectural blueprint for bringing a new level of trust to digital media, and how developers can apply this model to their own apps on Android.
A New Approach to Content Credentials
Generative AI can help us all to be more creative, productive, and innovative. But it can be hard to tell the difference between content that’s been AI-generated, and content created without AI. The ability to verify the source and history—or provenance—of digital content is more important than ever.
Content Credentials convey a rich set of information about how media such as images, videos, or audio files were made, protected by the same digital signature technology that has secured online transactions and mobile apps for decades. It empowers users to identify AI-generated (or altered) content, helping to foster transparency and trust in generative AI. It can be complemented by watermarking technologies such as SynthID.
Content Credentials are an industry standard backed by a broad coalition of leading companies for securely conveying the origin and history of media files. The standard is developed by the Coalition for Content Provenance and Authenticity (C2PA), of which Google is a steering committee member.
The traditional approach to classifying digital image content has focused on categorizing content as “AI” vs. “not AI”. This has been the basis for many legislative efforts, which have required the labeling of synthetic media. This traditional approach has drawbacks, as described in Chapter 5 of this seminal report by Google. Research shows that if only synthetic content is labeled as “AI”, then users falsely believe unlabeled content is “not AI”, a phenomenon called “the implied truth effect”. This is why Google is taking a different approach to applying C2PA Content Credentials.
Instead of categorizing digital content into a simplistic “AI” vs. “not AI”, Pixel 10 takes the first steps toward implementing our vision of categorizing digital content as either i) media that comes with verifiable proof of how it was made or ii) media that doesn't.
Pixel Camera attaches Content Credentials to any JPEG photo capture, with the appropriate description as defined by the Content Credentials specification for each capture mode.
Google Photos attaches Content Credentials to JPEG images that already have Content Credentials and are edited using AI or non-AI tools, and also to any images that are edited using AI tools. It will validate and display Content Credentials under a new section in the About panel, if the JPEG image being viewed contains this data. Learn more about it in Google Photos Help.
Given the broad range of scenarios in which Content Credentials are attached by these apps, we designed our C2PA implementation architecture from the onset to be:
Secure from silicon to applications
Verifiable, not personally identifiable
Useable offline
Secure from Silicon to Applications
Good actors in the C2PA ecosystem are motivated to ensure that provenance data is trustworthy. C2PA Certification Authorities (CAs), such as Google, are incentivized to only issue certificates to genuine instances of apps from trusted developers in order to prevent bad actors from undermining the system. Similarly, app developers want to protect their C2PA claim signing keys from unauthorized use. And of course, users want assurance that the media files they rely on come from where they claim. For these reasons, the C2PA defined the Conformance Program.
The Pixel Camera application on the Pixel 10 lineup hasachieved Assurance Level 2, the highest security rating currently defined by the C2PA Conformance Program. This was made possible by a strong set of hardware-backed technologies, including Tensor G5 and the certified Titan M2 security chip, along with Android’s hardware-backed security APIs. Only mobile apps running on devices that have the necessary silicon features and Android APIs can be designed to achieve this assurance level. We are working with C2PA to help define future assurance levels that will push protections even deeper into hardware.
Achieving Assurance Level 2 requires verifiable, difficult-to-forge evidence. Google has built an end-to-end system on Pixel 10 devices that verifies several key attributes. However, the security of any claim is fundamentally dependent on the integrity of the application and the OS, an integrity that relies on both being kept current with the latest security patches.
Hardware Trust: Android Key Attestation in Pixel 10 is built on support for Device Identifier Composition Engine (DICE) by Tensor, and Remote Key Provisioning (RKP) to establish a trust chain from the moment the device starts up to the OS, stamping out the most common forms of abuse on Android.
Genuine Device and Software: Aided by the hardware trust described above, Android Key Attestation allows Google C2PA Certification Authorities (CAs) to verify that they are communicating with a genuine physical device. It also allows them to verify the device has booted securely into a Play Protect Certified version of Android, and verify how recently the operating system, bootloader, and system software and firmware were patched for security vulnerabilities.
Genuine Application: Hardware-backed Android Key Attestation certificates include the package name and signing certificates associated with the app that requested the generation of the C2PA signing key, allowing Google C2PA CAs to check that the app requesting C2PA claim signing certificates is a trusted, registered app.
Tamper-Resistant Key Storage: On Pixel, C2PA claim signing keys are generated and stored using Android StrongBox in the Titan M2 security chip. Titan M2 is Common Criteria PP.0084 AVA_VAN.5 certified, meaning that it is strongly resistant to extracting or tampering with the cryptographic keys stored in it. Android Key Attestation allows Google C2PA CAs to verify that private keys were indeed created inside this hardware-protected vault before issuing certificates for their public key counterparts.
The C2PA Conformance Program requires verifiable artifacts backed by a hardware Root of Trust, which Android provides through features like Key Attestation. This means Android developers can leverage these same tools to build apps that meet this standard for their users.
Privacy Built on a Foundation of Trust: Verifiable, Not Personally Identifiable
The robust security stack we described is the foundation of privacy. But Google takes steps further to ensure your privacy even as you use Content Credentials, which required solving two additional challenges:
Challenge 1: Server-side Processing of Certificate Requests. Google’s C2PA Certification Authorities must certify new cryptographic keys generated on-device. To prevent fraud, these certificate enrollment requests need to be authenticated. A more common approach would require user accounts for authentication, but this would create a server-side record linking a user's identity to their C2PA certificates—a privacy trade-off we were unwilling to make.
Our Solution: Anonymous, Hardware-Backed Attestation. We solve this with Android Key Attestation, which allows Google CAs to verify what is being used (a genuine app on a secure device) without ever knowing who is using it (the user). Our CAs also enforce a strict no-logging policy for information like IP addresses that could tie a certificate back to a user.
Challenge 2: The Risk of Traceability Through Key Reuse. A significant privacy risk in any provenance system is traceability. If the same device or app-specific cryptographic key is used to sign multiple photos, those images can be linked by comparing the key. An adversary could potentially connect a photo someone posts publicly under their real name with a photo they post anonymously, deanonymizing the creator.
Our Solution: Unique Certificates. We eliminate this threat with a maximally private approach. Each key and certificate is used to sign exactly one image. No two images ever share the same public key, a "One-and-Done" Certificate Management Strategy, making it cryptographically impossible to link them. This engineering investment in user privacy is designed to set a clear standard for the industry.
Overall, you can use Content Credentials on Pixel 10 without fear that another person or Google could use it to link any of your images to you or one another.
Ready to Use When You Are - Even Offline
Implementations of Content Credentials use trusted time-stamps to ensure the credentials can be validated even after the certificate used to produce them expires. Obtaining these trusted time-stamps typically requires connectivity to a Time-Stamping Authority (TSA) server. But what happens if the device is offline?
This is not a far-fetched scenario. Imagine you’ve captured a stunning photo of a remote waterfall. The image has Content Credentials that prove that it was captured by a camera, but the cryptographic certificate used to produce them will eventually expire. Without a time-stamp, that proof could become untrusted, and you're too far from a cell signal, which is required to receive one.
To solve this, Pixel developed an on-device, offline TSA.
Powered by the security features of Tensor, Pixel maintains a trusted clock in a secure environment, completely isolated from the user-controlled one in Android. The clock is synchronized regularly from a trusted source while the device is online, and is maintained even after the device goes offline (as long as the phone remains powered on). This allows your device to generate its own cryptographically-signed time-stamps the moment you press the shutter—no connection required. It ensures the story behind your photo remains verifiable and trusted after its certificate expires, whether you took it in your living room or at the top of a mountain.
Building a More Trustworthy Ecosystem, Together
C2PA Content Credentials are not the sole solution for identifying the provenance of digital media. They are, however, a tangible step toward more media transparency and trust as we continue to unlock more human creativity with AI.
In our initial implementation of Content Credentials on the Android platform and Pixel 10 lineup, we prioritized a higher standard of privacy, security, and usability. We invite other implementers of Content Credentials to evaluate our approach and leverage these same foundational hardware and software security primitives. The full potential of these technologies can only be realized through widespread ecosystem adoption.
We look forward to adding Content Credentials across more Google products in the near future.

Challenge 1: Server-side Processing of Certificate Requests. Google’s C2PA Certification Authorities must certify new cryptographic keys generated on-device. To prevent fraud, these certificate enrollment requests need to be authenticated. A more common approach would require user accounts for authentication, but this would create a server-side record linking a user's identity to their C2PA certificates—a privacy trade-off we were unwilling to make.
Our Solution: Anonymous, Hardware-Backed Attestation. We solve this with Android Key Attestation, which allows Google CAs to verify what is being used (a genuine app on a secure device) without ever knowing who is using it (the user). Our CAs also enforce a strict no-logging policy for information like IP addresses that could tie a certificate back to a user.
Challenge 2: The Risk of Traceability Through Key Reuse. A significant privacy risk in any provenance system is traceability. If the same device or app-specific cryptographic key is used to sign multiple photos, those images can be linked by comparing the key. An adversary could potentially connect a photo someone posts publicly under their real name with a photo they post anonymously, deanonymizing the creator.
Our Solution: Unique Certificates. We eliminate this threat with a maximally private approach. Each key and certificate is used to sign exactly one image. No two images ever share the same public key, a "One-and-Done" Certificate Management Strategy, making it cryptographically impossible to link them. This engineering investment in user privacy is designed to set a clear standard for the industry.
Overall, you can use Content Credentials on Pixel 10 without fear that another person or Google could use it to link any of your images to you or one another.
Ready to Use When You Are - Even Offline
Implementations of Content Credentials use trusted time-stamps to ensure the credentials can be validated even after the certificate used to produce them expires. Obtaining these trusted time-stamps typically requires connectivity to a Time-Stamping Authority (TSA) server. But what happens if the device is offline?
This is not a far-fetched scenario. Imagine you’ve captured a stunning photo of a remote waterfall. The image has Content Credentials that prove that it was captured by a camera, but the cryptographic certificate used to produce them will eventually expire. Without a time-stamp, that proof could become untrusted, and you're too far from a cell signal, which is required to receive one.
To solve this, Pixel developed an on-device, offline TSA.
Powered by the security features of Tensor, Pixel maintains a trusted clock in a secure environment, completely isolated from the user-controlled one in Android. The clock is synchronized regularly from a trusted source while the device is online, and is maintained even after the device goes offline (as long as the phone remains powered on). This allows your device to generate its own cryptographically-signed time-stamps the moment you press the shutter—no connection required. It ensures the story behind your photo remains verifiable and trusted after its certificate expires, whether you took it in your living room or at the top of a mountain.
Building a More Trustworthy Ecosystem, Together
C2PA Content Credentials are not the sole solution for identifying the provenance of digital media. They are, however, a tangible step toward more media transparency and trust as we continue to unlock more human creativity with AI.
In our initial implementation of Content Credentials on the Android platform and Pixel 10 lineup, we prioritized a higher standard of privacy, security, and usability. We invite other implementers of Content Credentials to evaluate our approach and leverage these same foundational hardware and software security primitives. The full potential of these technologies can only be realized through widespread ecosystem adoption.
We look forward to adding Content Credentials across more Google products in the near future.
Adobe has warned of a critical security flaw in its Commerce and Magento Open Source platforms that, if successfully exploited, could allow attackers to take control of customer accounts.

A couple of months ago, a new paper demonstrated some new attacks against the Fiat-Shamir transformation. Quanta published a good article that explains the results.
This is a pretty exciting paper from a theoretical perspective, but I don’t see it leading to any practical real-world cryptanalysis. The fact that there are some weird circumstances that result in Fiat-Shamir insecurities isn’t new—many dozens of papers have been published about it since 1986. What this new result does is extend this known problem to slightly less weird (but still highly contrived) situations. But it’s a completely different matter to extend these sorts of attacks to “natural” situations...

We recently disrupted a sophisticated cybercriminal that used Claude Code to commit large-scale theft and extortion of personal data. The actor targeted at least 17 distinct organizations, including in healthcare, the emergency services, and government and religious institutions. Rather than encrypt the stolen information with traditional ransomware, the actor threatened to expose the data publicly in order to attempt to extort victims into paying ransoms that sometimes exceeded $500,000.
The actor used AI to what we believe is an unprecedented degree. Claude Code was used to automate reconnaissance, harvesting victims’ credentials, and penetrating networks. Claude was allowed to make both tactical and strategic decisions, such as deciding which data to exfiltrate, and how to craft psychologically targeted extortion demands. Claude analyzed the exfiltrated financial data to determine appropriate ransom amounts, and generated visually alarming ransom notes that were displayed on victim machines...

Abstract: The growing integration of LLMs into applications has introduced new security risks, notably known as Promptware—maliciously engineered prompts designed to manipulate LLMs to compromise the CIA triad of these applications. While prior research warned about a potential shift in the threat landscape for LLM-powered applications, the risk posed by Promptware is frequently perceived as low. In this paper, we investigate the risk Promptware poses to users of Gemini-powered assistants (web application, mobile application, and Google Assistant). We propose a novel Threat Analysis and Risk Assessment (TARA) framework to assess Promptware risks for end users. Our analysis focuses on a new variant of Promptware called Targeted Promptware Attacks, which leverage indirect prompt injection via common user interactions such as emails, calendar invitations, and shared documents. We demonstrate 14 attack scenarios applied against Gemini-powered assistants across five identified threat classes: Short-term Context Poisoning, Permanent Memory Poisoning, Tool Misuse, Automatic Agent Invocation, and Automatic App Invocation. These attacks highlight both digital and physical consequences, including spamming, phishing, disinformation campaigns, data exfiltration, unapproved user video streaming, and control of home automation devices. We reveal Promptware’s potential for on-device lateral movement, escaping the boundaries of the LLM-powered application, to trigger malicious actions using a device’s applications. Our TARA reveals that 73% of the analyzed threats pose High-Critical risk to end users. We discuss mitigations and reassess the risk (in response to deployed mitigations) and show that the risk could be reduced significantly to Very Low-Medium. We disclosed our findings to Google, which deployed dedicated mitigations...

In the early 1960s, National Security Agency cryptanalyst and cryptanalysis instructor Lambros D. Callimahos coined the term “Stethoscope” to describe a diagnostic computer program used to unravel the internal structure of pre-computer ciphertexts. The term appears in the newly declassified September 1965 document Cryptanalytic Diagnosis with the Aid of a Computer, which compiled 147 listings from this tool for Callimahos’s course, CA-400: NSA Intensive Study Program in General Cryptanalysis.
The listings in the report are printouts from the Stethoscope program, run on the NSA’s Bogart computer, showing statistical and structural data extracted from encrypted messages, but the encrypted messages themselves are not included. They were used in NSA training programs to teach analysts how to interpret ciphertext behavior without seeing the original message...

The term appears in the newly declassified September 1965 document Cryptanalytic Diagnosis with the Aid of a Computer, which compiled 147 listings from this tool for Callimahos’s course, CA-400: NSA Intensive Study Program in General Cryptanalysis.
The listings in the report are printouts from the Stethoscope program, run on the NSA’s Bogart computer, showing statistical and structural data extracted from encrypted messages, but the encrypted messages themselves are not included. They were used in NSA training programs to teach analysts how to interpret ciphertext behavior without seeing the original message...

There’s a travel scam warning going around the internet right now: You should keep your baggage tags on your bags until you get home, then shred them, because scammers are using luggage tags to file fraudulent claims for missing baggage with the airline.
First, the scam is possible. I had a bag destroyed by baggage handlers on a recent flight, and all the information I needed to file a claim was on my luggage tag. I have no idea if I will successfully get any money from the airline, or what form it will be in, or how it will be tied to my name, but at least the first step is possible...
