    Officials from the Bank of England, the Financial Conduct Authority, and the Treasury are working alongside the National Cyber Security Centre to examine vulnerabilities in critical IT systems that may have been exposed by the company’s latest AI model, per Reuters. The report, which cites individuals familiar with the discussions, indicates growing concern about how advanced AI tools could impact financial infrastructure.

    Meanwhile, the Bank of England, the Financial Conduct Authority, and the National Cyber Security Centre declined to comment, and the UK Treasury was not immediately available for a response, according to Reuters.

    Representatives from major British banks, insurers, and exchanges are expected to be briefed on the risks associated with the model, known as Claude Mythos Preview, during a meeting with regulators scheduled within the next two weeks, according to the Financial Times.

    The concerns in the UK follow similar developments in the United States. Reuters reported that U.S. Treasury Secretary Scott Bessent recently convened a meeting with major Wall Street banks to discuss the cybersecurity implications of the same AI model, highlighting the issue’s international scope.

    Anthropic has stated that the model is being deployed under a controlled initiative called “Project Glasswing,” which allows select organizations to use the unreleased Claude Mythos Preview for defensive cybersecurity purposes. According to Reuters, the company has positioned the effort as a way to identify and address vulnerabilities before they can be exploited.

    In a blog post published earlier this month, Anthropic said the model had already uncovered thousands of significant vulnerabilities across operating systems, web browsers, and other widely used software. These findings have raised both interest and concern among regulators and financial institutions, underscoring the dual-use nature of advanced AI systems, according to Reuters.
