Bessent summons bank executives over Anthropic cyber risk

Treasury Secretary Scott Bessent and Federal Reserve Chair Jerome Powell brought together a group of bank executives this week to discuss cybersecurity concerns in the wake of Anthropic’s new Mythos model, multiple people familiar with the meeting told The Hill. 

The meeting, held at the Treasury Department on Tuesday, came as Anthropic announced its latest AI model, Claude Mythos Preview, will be held back from public release because its capabilities are too advanced and risky to end up in bad actors’ hands. 

Several of the executives were already in Washington for the Financial Services Forum, an advocacy organization of the country’s eight largest banks, The Hill’s sources said.

Bloomberg, which first reported the meeting, said Bessent and Powell convened the group to warn of the possible risks the Mythos model could present to banks, citing anonymous people familiar with the matter. Reuters reported the meeting sought to ensure the banks were taking steps to defend their systems.  

Anthropic said this week it has been in discussions with US government officials about Claude Mythos Preview and “its offensive and defensive capabilities.” 

Those attending the meeting included Bank of America CEO Brian Moynihan, Citigroup CEO Jane Fraser, Morgan Stanley CEO Ted Pick, Goldman Sachs Group CEO David Solomon and Wells Fargo & Co. CEO Charles Scharf, Bloomberg reported. JPMorgan Chase CEO Jamie Dimon was not able to attend, one of the people familiar confirmed to The Hill.

Representatives for the banks and the Federal Reserve declined to comment. The Treasury Department did not immediately respond to The Hill. 

The Claude Mythos Preview model will be available to a select group of technology firms, including Apple, CrowdStrike, Amazon Web Services and Microsoft, according to Anthropic. 

These companies, aligned with more than 40 organizations that build or manage critical software infrastructure, will use Claude Mythos Preview in their defensive security work and findings will be shared by Anthropic with the whole industry. 

The consortium is part of Anthropic’s new initiative, Project Glasswing, which was formed after the company discovered the capabilities of Claude Mythos Preview.
