Treasury, Fed Meet Banks as Anthropic AI Cyber Risk Reaches Wall Street
Treasury and the Fed met major banks after concerns over Anthropic’s Mythos AI model. Follow-on reporting suggests some banks are now testing it defensively, signaling that frontier AI cyber capability is moving into financial risk and governance discussions.
US regulators convened major banks after Anthropic revealed an AI model capable of identifying and exploiting software vulnerabilities. Follow-on reporting suggests some banks are now testing the model defensively, underscoring how frontier AI cyber capability is entering financial risk discussions without confirmed new rules or incidents.
Subhead: New weekend reporting suggests the issue is widening from an urgent Treasury-Fed discussion into early defensive testing and broader regulatory coordination. (Bloomberg)
Direct answer: US Treasury Secretary Scott Bessent and Federal Reserve Chair Jerome Powell convened major bank leaders to discuss concerns tied to Anthropic’s Mythos model, which Anthropic says can identify and exploit vulnerabilities in major operating systems and web browsers. Since then, Bloomberg has reported that Wall Street banks are beginning to test Mythos internally for defensive vulnerability detection as administration officials encourage that work. (Bloomberg)
Why this matters now: The story is no longer just an urgent warning meeting. It now appears to include early defensive adoption by banks and wider government attention to the cybersecurity implications of frontier AI models. (Bloomberg)
