Overview
- Treasury Secretary Scott Bessent and Fed Chair Jerome Powell called in CEOs of systemically important banks Tuesday to warn that Anthropic’s new model could speed novel cyberattacks.
- Anthropic says Claude Mythos has already found thousands of high‑risk, previously unknown software flaws across major operating systems and web browsers, and it can sometimes produce working exploit code within hours.
- The company is keeping the tool closed under Project Glasswing, giving access to a limited group that includes Apple, Amazon, Microsoft, Google, the Linux Foundation, CrowdStrike, Palo Alto Networks, and Cisco to help find and fix bugs first.
- Germany’s cyber authority BSI says it is in contact with Anthropic, has not tested the tool, and expects upheaval in how vulnerabilities are handled, with implications for national and European security.
- Security leaders expect the window between discovery and exploitation to shrink, which could shift attacks away from classic bugs and force banks and software makers to speed patching and lock down movement inside their networks.
