Claude Mythos-1: 23,019 Vulnerabilities Found + Sonnet 4.8 Leaks (June Release?)The script covers two major Claude updates: Mythos-1 and leaked details on Sonnet 4.8. It claims Claude Mythos Preview scanned 1,000+ open-source projects in 30 days, found 23,019 vulnerabilities (6,202 high/critical) with a 90% true-positive verification rate, including large sets of issues for Cloudflare and Firefox, and it reportedly blocked a $1.5M wire-fraud attempt at a partner bank by detecting behavioral patterns without human intervention. It describes the challenge that AI can find vulnerabilities faster than humans can patch them, Anthropic’s response via Claude Security auto-patching, and an open-sourced bug-finding pipeline, plus Cisco building a similar system. It also discusses brief sightings of Mythos-1 Preview in Claude Code/Security despite public caution, Jack Clark’s Oxford remarks on AI risk, and accidental leaks indicating Sonnet/Opus 4.8 testing in Google Vertex with an expected mid-to-late June timeframe and new reasoning improvements.00:00 Mythos-1 and Sonnet Leaks00:26 Mythos Scanning Results01:05 Real World Bug Finds01:32 Bank Fraud Stopped02:13 Patch Backlog Problem02:54 Claude Security Auto Patching04:16 Mythos-1 Preview Spotted05:05 Safety Messaging Tension06:27 Sonnet 4.8 Leak Details06:55 Vertex Testing Signals07:27 Expected Sonnet 4.8 Upgrades08:11 Big Picture Takeaways09:09 Business Implications09:28 Three Common Objections10:25 How to Get Started11:15 Final Wrap Up
