U.S. Treasury Secretary Scott Bessent and Federal Reserve Chair Jerome Powell held an urgent meeting with CEOs from major Wall Street banks, including Citigroup Inc., Morgan Stanley, and Goldman Sachs Group Inc., to discuss the cybersecurity threats posed by Anthropic's advanced AI model, Mythos. This AI is capable of rapidly identifying software flaws and crafting sophisticated exploits, raising fears of systemic risks within the banking system. The meeting, which took place on Tuesday, highlighted a fundamental shift in regulators' perspectives, viewing AI not just as a technological challenge but as a potential catalyst for systemic events. Experts in the cryptocurrency and decentralized finance (DeFi) sectors have expressed concerns about Mythos' ability to discover and weaponize zero-day vulnerabilities, which could disrupt the financial infrastructure. Anthropic has taken a cautious approach by releasing Mythos only to a limited group of large technology and financial firms under a project named 'Project Glasswing.' The company has also been in a legal dispute with the Pentagon over its classification as a supply-chain risk.
