Top cybersecurity chief warns of AI dangers amid delayed rollout of Anthropic's Mythos model Mr Horne said AI did not yet constitute a national security threat in his view because the new models were "not finding new attacks, they're just exposing more security vulnerabilities". The UK's top cybersecurity chief has warned that organisations need to improve cyber defences with much greater urgency amid the delayed rollout of Anthropic's Claude Mythos model. Listen to this article Richard Horne, the head of the National Cybersecurity Centre, said models like Claude Mythos were "warning shots" about the risks of powerful Artificial Intelligence (AI) and that organisations needed to update cyber defences with "10 times urgency". Mythos is the latest model developed by leading AI firm Anthropic, which forms part of its wider system called Claude. Anthropic said the powerful tool could handle hacking and cybersecurity tasks better than humans, creating concern about the potential danger to digital services.

Mr Horne said AI did not yet constitute a national security threat in his view because the new models were "not finding new attacks, they're just exposing more security vulnerabilities". He continued: "We're in a kind of perfect storm where we have two forces - one huge technology disruption, one rising geopolitical tensions, and they come together. And cybersecurity's in the middle of them." Read more: Tech secretary to launch £500 million Sovereign AI Unit to help British firms Read more: AI
