Scan Your Codebase for Mythos-Class Vulnerabilities in 5 Minutes

By Jeremie Strand, co-founder at SkillSafe The threat is real and already priced This week, Anthropic published results from Mythos, their frontier AI model with full offensive security capabilities. The findings are worth sitting with: a 27-year-old signed integer overflow in OpenBSD's TCP SACK implementation, discovered for under $50. A 16-year-old out-of-bounds heap write in FFmpeg's H.264 decoder -- slice counter collision, roughly $10k across runs. A 17-year-old FreeBSD NFS RCE, CVE-2026-4747 -- stack buffer overflow in RPCSEC_GSS, unauthenticated root access. These aren't theoretical. They're sitting in production systems right now. Over 99% of what Mythos discovered remains unpatched. The model found 595 tier-1 and tier-2 crashes and 10 tier-5 full control-flow hijacks -- compared to 150-175 for prior models. It produced 181 working Firefox exploits versus 2 for Opus 4.6. Browser sandbox escapes via 4-vulnerability chains. Linux privilege escalation chains under $2,000 each. Hum
