Anthropic's cybersecurity collaboration (Project Glasswing, ~50 partner organisations) found over 10,000 high- or critical-severity vulnerabilities in its first month of operation, with 6,202 confirmed in 1,000+ open-source projects. Of 1,752 manually assessed vulnerabilities, 90.6% were confirmed valid and 62.4% rated high/critical — false-positive rates comparable to human testers. Cloudflare alone found 2,000 bugs (400 high/critical); Mozilla discovered 271 vulnerabilities in Firefox 150 (versus prior human findings); the UK AI Security Institute confirmed Mythos Preview solved both cyber range simulations end-to-end.
1,129 vulnerabilities have been reported to open-source maintainers; only 75 patched so far (90-day disclosure window still running; average patch time is two weeks). Anthropic also launched Claude Security (public beta) and a Cyber Verification Program alongside this update — plus custom skills and a code-scanning harness for qualifying customers.
Why it matters: this is the first public proof-of-scale for Mythos. The 90.6% signal fidelity figure turns Glasswing from a PR initiative into an auditable security infrastructure layer. For KwikGEO/KwikCOD agent deployments: Claude Security public beta is worth evaluating as a pre-production agent audit tool before any enterprise India D2C pilot.
