Key Points The Gentlemen RaaS The Gentlemen ransomware‑as‑a‑service (RaaS) operation is a relatively new group that emerged around mid‑2025. The operators advertise their services across multiple unde
Two weeks ago, Google’s Quantum AI group published a zero-knowledge proof of a quantum circuit so optimized, they concluded that first-generation quantum computers will break elliptic curve cryptograp
For the latest discoveries in cyber research for the week of 13th April, please download our Threat Intelligence Bulletin. TOP ATTACKS AND BREACHES The Los Angeles Police Department has reported a dat
We added a new chapter to our Testing Handbook: a comprehensive security checklist for C and C++ code. We’ve identified a broad range of common bug classes, known footguns, and API gotchas across C an
WhatsApp’s new “Private Inference” feature represents one of the most ambitious attempts to combine end-to-end encryption with AI-powered capabilities, such as message summarization. To make this poss
Code coverage is one of the most dangerous quality metrics in software testing. Many developers fail to realize that code coverage lies by omission: it measures execution, not verification. Test suite
This post is adapted from a talk I gave at [un]prompted, the AI security practitioner conference. Thanks to Gadi Evron for inviting me to speak. You can watch the recorded presentation below or downlo
We’re releasing a new Claude plugin for developing and auditing code that implements dimensional analysis, a technique we explored in our most recent blog post. Most LLM-based security skills ask the
Using dimensional analysis, you can categorically rule out a whole category of logic and arithmetic bugs that plague DeFi formulas. No code changes required, just better reasoning! One of the first le
Account abstraction transforms fixed “private key can do anything” models into programmable systems that enable batching, recovery and spending limits, and flexible gas payment. But that programmabili
If you’ve ever done Linux memory forensics, you know the frustration: without debug symbols that match the exact kernel version, you’re stuck. These symbols aren’t typically installed on production sy
Before launching their Comet browser, Perplexity hired us to test the security of their AI-powered browsing features. Using adversarial testing guided by our TRAIL threat model, we demonstrated how fo
Two popular AES libraries, aes-js and pyaes, “helpfully” provide a default IV in their AES-CTR API, leading to a large number of key/IV reuse bugs. These bugs potentially affect thousands of downstrea
Last year, our engineers submitted over 375 pull requests that were merged into non–Trail of Bits repositories, touching more than 90 projects from cryptography libraries to the Rust compiler. This wo
Software signatures carry an invisible expiration date. The container image or firmware you sign today might be deployed for 20 years, but the cryptographic signature protecting it may become untrustw
