Anthropic is preparing to brief the Financial Stability Board (FSB) on cybersecurity vulnerabilities identified by its “Mythos” AI model. Multiple reports say the meeting is requested by Bank of England Governor Andrew Bailey, who chairs the global body focused on monitoring financial-system risks, and that it will involve regulators represented through FSB channels, including consideration by G20 finance ministries and central banks. The reporting frames the discussions as part of efforts to assess potential risks associated with the model after concerns raised by Bailey. Anthropic’s briefings are expected to cover the vulnerabilities Mythos has been finding and related implications for cyber defense. While the sources describe the meeting as regulatory outreach requested by Bailey, they also characterize it as a move to explain what the model is identifying rather than as a public enforcement action. The Financial Times is cited as the basis for the details of the meeting request and the planned regulator engagement. No additional specifics about the nature or severity of the vulnerabilities are provided in the excerpts.
