UK regulators, including the FCA, Bank of England and HM Treasury, have urged banks to prepare for a new wave of powerful cyberattack driven by frontier AI models.
These advanced systems represent a major leap in capability, surpassing skilled human experts in speed, scale and cost.
The authorities warn that current models already pose serious threats to cyber security and operational resilience, with risks set to grow as technology advances.
Anthropic’s Mythos model has exposed thousands of zero-day vulnerabilities in web browsers and systems.
Banks testing the model, report it can identify hundreds to thousands of low-to-moderate risks and chain them into larger threats.
It also excels at spotting weaknesses in both proprietary and open-source code, increasing pressure on banks to modernise ageing infrastructure.
Bank of England Governor Andrew Bailey described the development as potentially “cracking the whole cyber risk world open.”
Anthropic has agreed to brief global finance officials on findings.
Regulators stress that banks must strengthen governance, investment, vulnerability management, access controls and response capabilities to counter faster, more disruptive AI-driven attacks.
