For the past year, we’ve worked with the Python Package Index (PyPI) on a new security feature for the Python ecosystem: index-hosted digital attestations, as specified in PEP 740. These attestations improve on traditional PGP signatures (which have been disabled on PyPI) by providing key usability, index verifiability, cryptographic strength, and provenance properties that bring […]
This is a joint post with Alpha-Omega—read their announcement post as well! We’re starting a new project in collaboration with Alpha-Omega and OpenSSF to improve the transparency and security of Homebrew. This six-month project will bring cryptographically verifiable build provenance to homebrew-core, allowing end users and companies to prove that Homebrew’s packages […]
Read the official announcement on the PyPI blog as well! For the past year, we’ve worked with the Python Package Index to add a new, more secure authentication method called “trusted publishing.” Trusted publishing eliminates the need for long-lived API tokens and passwords, reducing the risk of supply chain attacks and credential leaks while also […]
Tl;dr: Trail of Bits has launched a practice focused on machine learning and artificial intelligence, bringing together safety and security methodologies to create a new risk assessment and assurance program. This program evaluates potential bespoke risks and determines the necessary safety and security measures for AI-based systems. If you’ve read any news over the past […]
A new tool for Windows RPC research By Aaron LeMasters Trail of Bits is releasing a new tool for exploring RPC clients and servers on Windows. RPC Investigator is a .NET application that builds on the NtApiDotNet platform for enumerating, decompiling/parsing and communicating with arbitrary RPC servers. We’ve added visualization and additional features that offer […]
Read the official announcement on the Sigstore blog as well! Trail of Bits is thrilled to announce the first stable release of sigstore-python, a client implementation of Sigstore that we’ve been developing for nearly a year! This work has been graciously funded by Google’s Open Source Security Team (GOSST), who we’ve also […]
Andrew Haberlandt During my summer internship at Trail of Bits, I worked on the fork of the RBPF JIT compiler that is used to execute Solana smart contracts. The RBPF JIT compiler plays a critical role on the Solana blockchain, as it facilitates the execution of contracts on validator nodes by default. Before my […]
Originally published on October 6, 2021 TL;DR: Version 5.0.1 of osquery, a cross-platform, open-source endpoint visibility agent, is now available. This release is an exciting milestone for the project, as it introduces an EndpointSecurity-based process events table for macOS. Read on to learn how we integrated EndpointSecurity into osquery […]
TL;DR: Sinter is the first available open-source endpoint protection agent written entirely in Swift, with support for Apple’s new EndpointSecurity API from first principles. Sinter demonstrates how to build a successful event-authorization security agent, and incorporates solutions to many of the challenges that all endpoint protection agents will face as they migrate from kernel-mode to […]
(This posting is cross-posted between the Zeek blog and the Trail of Bits blog). The Zeek Network Security Monitor provides a powerful open-source platform for network traffic analysis. However, from its network vantage point, Zeek lacks access to host-level semantics, such as the process and user accounts that are responsible for any connections observed. The […]
Has it really been 3 months since Trail of Bits hosted QueryCon? We’ve had such a busy and productive summer that we nearly forgot to go back and reflect on the success of this event! On June 20-21, Trail of Bits partnered with Kolide and Carbon Back to host the 2nd annual QueryCon, at the […]
During my summer at Trail of Bits, I took full advantage of the latest C++ language features to build a new SQLite wrapper from scratch that is easy to use, lightweight, high performant, and concurrency friendly—all in under 750 lines of code.
People interested in joining Trail of Bits often ask us what it’s like to work on the Engineering Services team. We felt that the best answer would be a profile of some of the talented individuals on our team, and let them describe their experiences at Trail of Bits in their own words. Today, we’re […]
Since March, Trail of Bits has been working with the Python Software Foundation to add two-factor authentication (2FA) to Warehouse, the codebase that powers PyPI. As of today, PyPI members can enable time-based OTP (TOTP) and WebAuthn (currently in beta). If you have an account on PyPI, go enable your preferred 2FA method before you […]
For months, Facebook has been heavily refactoring the entire osquery codebase, migrating osquery away from standard development tools like CMake and integrating it with Facebook’s internal tooling. Their intention was to improve code quality, implement additional tests, and move the project to a more modular architecture. In practice, the changes sacrificed support for a number […]
