Mozilla has successfully used Anthropic's Mythos AI model to identify 271 security vulnerabilities in Firefox with 'almost no false positives,' marking a significant advancement in AI-assisted security testing. The breakthrough was achieved through improvements in the AI models and a custom 'harness' that guides the analysis process, addressing previous issues with hallucinated bug reports. This development validates Mozilla CTO's earlier claims about AI's potential to help defenders gain an upper hand against zero-day vulnerabilities.
