Your bank is being patched at emergency speed right now, and you probably have no idea why. Anthropic’s Mythos — the AI model so dangerous it was never publicly released — is ripping through Wall Street’s cybersecurity posture like a chainsaw through wet paper. US banks are uncovering thousands of vulnerabilities they never knew existed. Japan’s three largest banks just got access. And the cybersecurity community is arguing about whether any of this is actually new. ...

The pretense is officially over. For years, Wall Street executives delivered a comforting mantra: AI will enhance your work, not replace it. This week, as Q1 2026 earnings rolled in, that narrative crumbled in spectacular fashion. JPMorgan Chase, Citigroup, Bank of America, Goldman Sachs, Morgan Stanley, and Wells Fargo collectively reported $47 billion in profits — up 18% year-over-year — while shedding approximately 15,000 employees. More money, fewer humans. The math is brutal and undeniable. ...

The IMF spring meetings were supposed to be about trade policy. Instead, every closed-door session circled back to one word: Mythos. Anthropic’s latest AI model has found thousands of high-severity vulnerabilities across every major operating system and browser on the planet. Not theoretical weaknesses. Exploitable ones. And it chains them together autonomously. Finance ministers are terrified. The global banking system just became the softest target on earth. What Mythos Actually Does Mythos doesn’t just scan for bugs. It reasons about them. It discovers a buffer overflow in one system, a privilege escalation in another, and a logic flaw in a third — then stitches them into a working attack chain without human guidance. ...

The Treasury Secretary and the Fed Chair don’t pull bank CEOs into surprise meetings over product launches. They do it over threats. And last week, the threat was an AI model. Anthropic’s Claude Mythos Preview — announced April 7 — can autonomously discover and exploit zero-day vulnerabilities across every major operating system and web browser. Three days later, Treasury Secretary Scott Bessent and Fed Chair Jerome Powell had executives from Citi, Bank of America, Wells Fargo, Goldman Sachs, and Morgan Stanley in a room. ...
