Vendetect is our new open-source tool for detecting copied and vendored code between repositories. It uses semantic fingerprinting to identify similar code even when variable names change or comments disappear. More importantly, unlike academic plagiarism detectors, it understands version control history, helping you trace vendored code back to its exact source commit.
Deptective, our new open-source tool, automatically finds the packages needed to install software dependencies. It does so not based on the software’s self-reported requirements, but by observing what the software needs at runtime.
Our CRS (Cyber Reasoning System), Buttercup, is now competing in the one and only scored round of DARPA’s AI Cyber Challenge (AIxCC) against six other teams to see which autonomous AI-driven system can find and patch the most software vulnerabilities.
Datasig generates compact, unique fingerprints for AI/ML datasets that let you compare training data with high accuracy—without needing access to the raw data itself.
This critical capability helps AIBOM (AI bill of materials) tools detect data-borne vulnerabilities that traditional security tools completely miss.
This blog post highlights key points from our new white paper Preventing Account Takeovers on Centralized Cryptocurrency Exchanges, which documents ATO-related attack vectors and defenses tailored to CEXes. Imagine trying to log in to your centralized cryptocurrency exchange (CEX) account and your password and username just… don’t work. You […]
If you love exploit mitigations, you may have heard of a new system call named mseal landing into the Linux kernel’s 6.10 release, providing a protection called “memory sealing.” Beyond notes from the authors, very little information about this mitigation exists. In this blog post, we’ll explain what this syscall is, including […]
In the race to secure cloud applications, AWS Nitro Enclaves have emerged as a powerful tool for isolating sensitive workloads. But with great power comes great responsibility—and potential security pitfalls. As pioneers in confidential computing security, we at Trail of Bits have scrutinized the attack surface of AWS Nitro Enclaves, uncovering potential […]
(Would you get up and throw it away?) [sing to the tune of The Beatles – With A Little Help From My Friends] Here’s a riddle: when new GPUs are constantly being produced, product cycles are ~18-24 months long, and each cycle doubles GPU power (per Huang’s Law), what […]
Today we’re going to provision some cloud infrastructure the Max Power way: by combining automation with unchecked AI output. Unfortunately, this method produces cloud infrastructure code that 1) works and 2) has terrible security properties. In a nutshell, AI-based tools like Claude and ChatGPT readily provide extremely bad cloud infrastructure provisioning code, […]
This is a joint post with the Homebrew maintainers; read their announcement here! Last summer, we performed an audit of Homebrew. Our audit’s scope included Homebrew/brew itself (home of the brew CLI), and three adjacent repositories responsible for various security-relevant aspects of Homebrew’s operation: Homebrew/actions: a repository of custom GitHub Actions used […]
Last November, we announced our collaboration with Alpha-Omega and OpenSSF to add build provenance to Homebrew. Today, we are pleased to announce that the core of that work is live and in public beta: homebrew-core is now cryptographically attesting to all bottles built in the official Homebrew CI. You […]
You’ve reached computer programming nirvana. Your journey has led you down many paths, including believing that God wrote the universe in LISP, but now the truth is clear in your mind: every problem can be solved by writing one more compiler. It’s true. Even our soon-to-be artificially intelligent overlords are nothing but […]
Trail of Bits is releasing BTIGhidra, a Ghidra extension that helps reverse engineers by inferring type information from binaries. The analysis is inter-procedural, propagating and resolving type constraints between functions while consuming user input to recover additional type information. This refined type information produces more idiomatic decompilation, enhancing reverse engineering comprehension. The […]
Intermediate languages (IRs) are what reverse engineers and vulnerability researchers use to see the forest for the trees. IRs are used to view programs at different abstraction layers, so that analysis can understand both low-level code aberrations and higher levels of flawed logic mistakes. The setback is that bug-finding tools are often pigeonholed into choosing […]
WNF (Windows Notification Facility) is an undocumented notification mechanism that allows communication inside processes, between processes, or between user mode processes and kernel drivers. Similar to other notification mechanisms like ETW (Event Tracing for Windows) and ALPC (Advanced Local Procedure Call), WNF communication happens over different “channels,” each representing […]
