IMF Chief, Treasury and Fed Highlight Anthropic Mythos Cyber Risks as Project Glasswing Rolls Out to Major U.S. Firms
IMF Managing Director Kristalina Georgieva warned that Anthropic’s Claude Mythos Preview poses “massive cyber risks” to the international monetary system and urged central banks and financial institutions to shore up guardrails as “time is not our friend.” Treasury Secretary Scott Bessent and Fed Chair Jerome Powell convened an emergency meeting with CEOs of systemically important banks to discuss those risks after Anthropic, via a restricted Project Glasswing rollout to select firms (including Amazon, Apple, Cisco, JPMorgan and Nvidia), said Mythos has uncovered thousands of high‑severity vulnerabilities across major operating systems and browsers; Anthropic has briefed U.S. officials amid controversy over a collapsed Pentagon contract and a recent supply‑chain‑risk designation.
📌 Key Facts
- Treasury Secretary Scott Bessent and Federal Reserve Chair Jerome Powell held a last‑minute, in‑person, closed‑door meeting Tuesday at Treasury headquarters in Washington, D.C., summoning major bank CEOs designated by the Fed as 'structurally important' to discuss cybersecurity risks from Anthropic’s Claude Mythos Preview.
- Confirmed and involved banks included Bank of America (CEO Brian Moynihan confirmed attending), Goldman Sachs, Citigroup, Morgan Stanley and Wells Fargo; JPMorgan CEO Jamie Dimon was invited to the meeting but did not attend.
- Anthropic is conducting a restricted deployment called Project Glasswing, sharing the Mythos model only with selected major companies such as Amazon, Apple, Cisco, JPMorgan Chase and Nvidia.
- Anthropic publicly claims its Claude Mythos Preview can outperform all but the most skilled humans at finding and exploiting software vulnerabilities and has already uncovered 'thousands' of high‑severity, previously unknown flaws across every major operating system and web browser.
- Anthropic has privately briefed senior U.S. government officials and key industry stakeholders on Mythos’s capabilities; the company previously had a $200 million Pentagon contract that collapsed after it refused to support autonomous weapons and domestic surveillance, prompting the Pentagon to label Anthropic a supply‑chain risk and leading to a recent federal appeals‑court rejection of Anthropic’s attempt to block that designation.
- IMF Managing Director Kristalina Georgieva explicitly named Anthropic’s Claude Mythos as a concern, warned the world currently lacks the ability to protect the international monetary system against 'massive cyber risks' from advanced AI ('time is not our friend'), and urged central banks and key financial institutions to cooperate and establish guardrails to protect financial stability.
- Security experts quoted by reporters say hackers are already using existing AI tools to sharpen phishing and ransomware attacks and expect 'a lot more vulnerabilities' and cyberattacks once capabilities like Mythos become more widely available.
- The combination of high‑level IMF warnings (delivered on a major political program) and the Treasury/Fed emergency meeting signals an effort to elevate AI‑driven cyber‑risk — particularly from Anthropic’s Mythos — into mainstream U.S. financial stability and policy discussions.
