Prompt injection engineering for attackers: Exploiting GitHub CopilotPrompt injection pervades discussions about security for LLMs and AI agents. But there is little public information on how to write powerful, discreet, and reliable prompt injection exploits. In this post, we will design and implement a prompt injection exploit targeting GitHub’s Copilot Agent, with a focus on maximizing reliability and minimizing the odds of detection.
Detecting Iterator Invalidation with CodeQLIterator invalidation is a common and subtle class of C++ bugs that often leads to exploitable vulnerabilities. During my Trail of Bits internship this summer, I developed Itergator, a set of CodeQL classes and queries for analyzing and discovering iterator invalidation. Results are easily interpretable by an auditor, […]
