Anthropic's Claude Mythos Preview AI model has raised major concerns among investors and policymakers, leading to a staggering $2 trillion selloff in enterprise software stocks. This unprecedented market reaction prompted an emergency meeting at the US Treasury, where Treasury Secretary Scott Bessent and Federal Reserve Chair Jerome Powell convened with CEOs from major banks, including Bank of America and Citigroup, to discuss the cybersecurity risks associated with the AI model. Jamie Dimon, CEO of JPMorgan Chase, highlighted in his annual shareholder letter that AI could worsen cybersecurity threats, necessitating substantial defensive investments. In response to the vulnerabilities identified by Claude Mythos Preview, which has uncovered thousands of high-severity flaws, Anthropic launched Project Glasswing. This initiative, involving major tech companies like Amazon Web Services and Microsoft, aims to use the AI defensively to secure critical software infrastructure, with Anthropic committing up to $100 million in usage credits. The situation underscores the complex nature of advanced AI models, which can be both a boon and a threat to cybersecurity.
