Anthropic Mythos Triggers Fresh Cybersecurity Concerns for Major US Banks

Anthropic's new AI model, Claude Mythos Preview, has drawn close attention from U.S. financial officials after the company limited access to a small group of firms. The model was introduced through Anthropic's Project Glasswing program, which focuses on defensive cybersecurity work. U.S. officials then held meetings with banks and technology leaders to review potential cyber risks associated with advanced AI systems.

US Treasury Secretary Scott Bessent and Federal Reserve Chair Jerome Powell met with major bank executives in Washington this week to discuss cyber threats tied to advanced AI tools. The meeting focused on how banks should prepare for systems capable of detecting software weaknesses at high speed.

Kevin Hassett, director of the White House National Economic Council, later said Bessent and Powell went through the cyber risks with bank leaders so they understood the issue clearly. The session showed that financial authorities are treating AI-related as an urgent matter.

The concern centers on the banking system's heavy dependence on software, digital records, and networked operations. Any weakness in those systems can create operational problems, service outages, or risks to customer accounts if attackers gain an advantage.
