The Bank of England plans to discuss the impact of Anthropic PBC’s new AI model with financial institutions, as UK regulators join their peers in the US and elsewhere in raising alarms over the risks posed by the tool.
Anthropic’s Mythos model will be on the agenda for the BOE’s next Cross Market Operational Resilience Group and CMORG AI Taskforce meetings, scheduled within the next two weeks, according to a person with knowledge of the matter. The meetings, earlier reported by the Telegraph, will include representatives from the Treasury, the Financial Conduct Authority and the National Cyber Security Centre.
Wall Street banks have started testing Mythos internally after the Trump administration this week warned executives they should take the model seriously and deploy its capabilities to detect vulnerabilities. The Bank of Canada on Friday also met with banks and financial firms to discuss the cybersecurity risks posed by Mythos.
The meetings reflect growing concern among regulators that a new breed of cyberattacks is one of the biggest risks facing the financial industry.
Anthropic’s Mythos is a sophisticated new model capable of identifying and exploiting vulnerabilities in every major operating system and web browser, the company has said.
