I do fuzzing on Google's Open Source Security Team.
I work on OSS-Fuzz/ClusterFuzz/FuzzBench.
Speaking on behalf of myself, not my employer.

XBOW found a critical auth bypass (CVE-2024-50334) in a widely-used open-source Q&A site, fully autonomously! Nico Waisman and I wrote up a post walking through the methodology it used – IMO it's a super cool bug and fascinating trace

My LLM analyzed a vulnerability in a Linux library and even created a PoC! This is expected to be used in Browser's Sandbox Escape as well. (Actually accessible) We will make this tool available for Android and browsers too! Actually my LLM was able to find several successful

The original link I posted for the OSS-Fuzz PhD internship was wrong, sorry to folks who applied to the research intern position. Please re-apply to the one below. The correct one is for the SWE intern position. 🤦

Auto generating #fuzzing harnesses by way of program analysis and #LLMs! New blog post "Minimal LLM-based fuzz harness generator": adalogics.com/blog/minimal-l… We show how you can generate a sophisticated fuzz harness synthesis tool with a few lines of code.
