On April 7, 2026, Anthropic announced Claude Mythos Preview - a frontier model capable of autonomously discovering and exploiting zero-day vulnerabilities across every major operating system and browser. They assembled Project Glasswing, a $100M defensive coalition with Microsoft, Google, Apple, AWS, CrowdStrike, and Palo Alto Networks. They reported thousands of vulnerabilities, including a 27-year-old OpenBSD flaw and a 16-year-old FFmpeg bug. It was a watershed moment for AI security. And the findings were individual bugs - specific flaws in specific locations.
