Anthropic has released its first progress report on Project Glasswing, the ambitious cybersecurity initiative launched in April aimed at turning advanced AI into a powerful defensive weapon against AI-powered cyberattacks.
Powered by the unreleased Claude Mythos Preview model, the project has already produced impressive outcomes in its first month, uncovering more than 10,000 vulnerabilities across partner organizations.
The initiative represents a sophisticated acknowledgment of a growing reality in cybersecurity: as AI systems become more capable, the most effective defense may lie in deploying similarly advanced AI to hunt for weaknesses before malicious actors can exploit them.
Strong Results from Key Partners
The report highlights how Mythos Preview is outperforming traditional security methods in both speed and thoroughness. Most participating organizations have each identified hundreds of critical or high-severity vulnerabilities in their software using the model.
Notable examples include:
- Cloudflare discovered 2,000 bugs, with 400 classified as high or critical severity.
- Mozilla identified and fixed 271 vulnerabilities in Firefox — a tenfold increase compared to previous scans using an earlier Claude model.
- Microsoft has linked larger-than-usual patch releases to vulnerabilities uncovered through Mythos Preview.
Anthropic also conducted its own scans of 1,000 open-source projects, identifying 6,202 high- and critical-severity vulnerabilities out of a total of 23,019. One independent security research firm reportedly used the model to successfully breach macOS, chaining exploits in a system long considered among the most secure.
These results suggest Mythos Preview is operating at a level where it can systematically map and prioritize…
