Bessent and Powell assembled the group at Treasury’s headquarters in Washington on Tuesday to make sure banks are aware of possible future risks raised by Anthropic’s Mythos and potential similar models, and are taking precautions to defend their systems, according to people familiar with the matter who asked not to be identified citing the private discussions.

The previously unreported meeting, arranged on short notice, is another sign that regulators consider the possibility of a new breed of cyber attacks as one of the biggest risks facing the financial industry.

Powell’s participation in the meeting signaled that the concern was one of systemic risk, and not tied to the Trump administration’s previous clashes with Anthropic, said some of the people. The Fed, with its network of examiners, is also deeply familiar with banking operations.
“We’re taking every step we can to make sure that everybody is safe from these potential risks, including Anthropic agreeing to hold back the public release of the model until our officials have figured everything out,” National Economic Council Director

Regulators’ caution about the power of the model in hackers’ hands echoes Anthropic’s own prudence. Anthropic has
Anthropic has said that it has been in discussions prior to its recent release with US officials about Mythos and its “offensive and defensive cyber capabilities.”
In releasing Mythos to a very limited set of companies, Anthropic pointed to several vulnerabilities that the AI system was capable of both identifying and potentially exploiting during testing. None of the examples related specifically to financial institutions, but in one instance, the firm’s security team said it was able to compromise a web browser so that a website set up by a hacker could read data from another website “e.g., the victim’s bank.”
Mythos Preview “fully autonomously discovered” a way of reading information stored in “multiple different web browsers” and then used that ability to find ways to exploit them, according to a post from Anthropic’s security team.

In recent years, regulators have required banks to hold some capital tied to the potential for cyber attacks, as well as other so-called operational risks such as lawsuits and rogue employees. Banks have sometimes chafed at those requirements, given that operational risk is more difficult to measure than the market and credit risks that also factor into banks’ capital levels.
