Autonomous Security Agent Discovers 21 Zero-Day Vulnerabilities in FFmpeg
By

Pure flour-power. Hearty enough to carry you through lunch.
Summary
depthfirst's autonomous security agent discovered 21 zero-day vulnerabilities in FFmpeg, a widely used multimedia framework. The agent produced concrete, reproducible Proof-of-Concept (PoC) inputs to confirm findings at a fraction of typical costs ($1k vs. $10k). Several vulnerabilities had been latent for 15-20 years, and the team developed a PoC demonstrating a Remote Code Execution (RCE) exploit primitive. This discovery came after intensive security analysis by Google and Anthropic.

· 4 pulleddepthfirst's production autonomous security agent discovered 21 zero-day vulnerabilities in FFmpeg, after intensive security analysis by Google and Anthropic.
Moving beyond theoretical analysis, our agent produces concrete, reproducible PoC inputs to confirm its findings at a fraction of the costs ($1k vs. $10k).
Several of the findings had been sitting latent for 15 to 20 years.
We explored the exploitability of the issues and developed a PoC demonstrating a RCE exploit primitive.
