British financial regulators are in urgent talks with cybersecurity officials and major banks over risks linked to Anthropic’s latest AI model, according to the Financial Times. The discussions follow similar concerns raised in the United States.

LONDON: British financial regulators are holding urgent discussions with the government’s cybersecurity agency and major financial institutions to evaluate risks associated with Anthropic’s latest artificial intelligence model, according to the Financial Times.

As per details, officials from the Bank of England, the Financial Conduct Authority and HM Treasury are in contact with the National Cyber Security Centre to review possible weaknesses in critical information technology systems that were highlighted by Anthropic’s newest model, the newspaper reported on Sunday.

The report said representatives of major British banks, insurers and exchanges are expected to receive a briefing from regulators within the next fortnight on cybersecurity risks linked to the model, Claude Mythos Preview. The Financial Times cited two people briefed on the talks.

Reuters said it could not immediately verify the report independently.

Anthropic did not respond to Reuters’ request for comment. The Bank of England declined to comment, while HM Treasury, the National Cyber Security Centre and the Financial Conduct Authority were not immediately available for comment.

US meeting preceded UK discussions

The development comes after a meeting convened by US Treasury Secretary Scott Bessent with major Wall Street banks on the model’s cyber risk potential, Reuters reported on Friday, citing two sources.

Anthropic has said the model is being deployed under Project Glasswing, which it described as a controlled initiative allowing selected organisations to use the unreleased Claude Mythos Preview model for defensive cybersecurity purposes.

Earlier this month, the AI startup said in a blog post that the model had already identified thousands of major vulnerabilities across operating systems, web browsers and other widely used software.

Focus on critical systems

The reported talks in Britain centre on the potential implications for critical IT infrastructure used by the financial sector. According to the Financial Times report cited by Reuters, regulators and cybersecurity officials are examining how vulnerabilities identified by the model could affect key systems.

The expected briefing for banks, insurers and exchanges indicates that UK authorities are moving to assess the cybersecurity implications of the technology for the country’s financial system. The discussions involve the Bank of England, the Financial Conduct Authority, HM Treasury and the National Cyber Security Centre, as reported by the newspaper.

That word was used by Anthropic in its blog post to describe the number of major vulnerabilities the model had already identified across operating systems, web browsers and other commonly used software.

The latest developments in the UK follow similar attention in the United States, where senior officials and major banks have also discussed the model’s possible cyber risk implications.
