The top U.S. banking CEOs, including Citigroup's Jane Fraser, Morgan Stanley's Ted Pick, Bank of America's Brian Moynihan, Wells Fargo's Charlie Scharf, and Goldman Sachs' David Solomon, were among the leaders at an urgent meeting at Treasury headquarters on April 8 due to concerns that Anthropic’s latest AI model, Mythos, could lead to greater cyber risk. The meeting was held to ensure that banks are aware of possible future risks and taking precautions to defend their systems. The company's model can rapidly spot software flaws and exploit sophisticated exploits, raising fears of systemic risks in the banking system. The day after the meeting, Anthropic revealed it was releasing a version of Mythos to a select group of companies under an initiative called Project Glasswing, which participants include Amazon, Apple, and JPMorgan. The move signals that policymakers now view AI-driven cyber risk as a financial stability concern, not just a technology issue.
