Project Glasswing is Anthropic's $100 million initiative to deploy Claude Mythos for defensive cybersecurity before the technology reaches adversaries. Here's how it works, who's involved, what it means for open-source software, and what developers and security teams should do right now.
Claude Mythos didn't just score well on benchmarks — it autonomously discovered thousands of critical vulnerabilities in every major operating system and browser. This deep dive explains how it works: from hypothesizing bugs in code to chaining four exploits into a full sandbox escape.
