U.S. Treasury Secretary Scott Bessent and Federal Reserve Chair Jerome Powell summoned major bank chiefs to a meeting in Washington last week to warn of ?cyber risks posed by Anthropic’s latest AI model. Anthropic launched the powerful Claude Mythos model earlier in the week to a small number of businesses, including Amazon, Apple and Microsoft, but held back on a broader release, citing concerns that the model could expose previously unknown ?cybersecurity vulnerabilities. A blogpost published by Anthropic at the beginning of the month said that AI models had surpassed “all but the most skilled humans at finding and exploiting software vulnerabilities,” adding: “The fallout – for economies, public safety, and national security – could be severe.” The Treasury-hosted meeting aimed to ensure banks are aware of the risks posed by Mythos and similar models and are taking ?steps ?to defend their systems, a source said.
