US Treasury Secretary Scott Bessent and Federal Reserve Chair Jerome Powell convened an urgent meeting with top bank executives in Washington to discuss cybersecurity risks associated with Anthropic's newly launched Mythos AI model. This model, capable of identifying and exploiting vulnerabilities across major operating systems and web browsers, raised alarms among officials, prompting them to urge banks to enhance their cybersecurity measures. Anthropic, led by Dario Amodei, has limited access to Mythos to around 40 technology firms, including major players like Microsoft and Google. The meeting took place as many CEOs were already in Washington for other engagements, with notable attendees from Citigroup, Morgan Stanley, Bank of America, Wells Fargo, and Goldman Sachs. Additionally, a federal appeals court recently upheld the Pentagon's decision to blacklist Anthropic, labeling it a national security risk due to its refusal to comply with certain usage restrictions, potentially costing the company billions in lost contracts and damaging its reputation.
