Anthropic Briefing Financial Stability Board on Mythos Cybersecurity Findings
Anthropic is preparing to brief the Financial Stability Board (FSB) on the cybersecurity vulnerabilities its Mythos model has been identifying in the global financial system, as reported by The Financial Times.
Bank of England Governor Andrew Bailey, who chairs the FSB, has requested the briefing for G20 finance ministries and central banks. Bailey previously expressed concern about Mythos during a speech at Columbia University, highlighting its potential to "crack the whole cyber risk world open."
Mythos, an unreleased cybersecurity model, is designed to surface long-standing vulnerabilities in browsers, infrastructure, and software. Anthropic claims it has already found thousands of high-severity flaws across major operating systems and browsers, with success rates exceeding 83% when developing working exploits during internal testing.
This briefing follows a series of discussions initiated by Bailey’s remarks, involving banks worldwide:
- Briefings were held for UK banks shortly after his speech.
- The Federal Reserve and US Treasury convened CEOs of major American banks on the same risk.
- Australia’s securities regulator joined the watch-list in early May.
- Euro-area finance ministers raised access demands, and Mythos has been delivered to Japanese megabanks.
Key points from the briefing will not include:
Access to Mythos is currently limited through ‘Project Glasswing’, with only 40-50 organisations, including major tech companies like AWS, Apple, Google, Microsoft, Nvidia, Cisco, and JPMorgan, having early access. Bank supervisors outside this group have expressed desire for direct or regulator-mediated access.
