Five Eyes intelligence alliance warns of threats from new AI models

Cutting-edge artificial intelligence technology is poised to supercharge offensive hacking capabilities, and urgent action is needed to face up to the threat, US, UK, Canadian, Australian and New Zealand officials have said. "Frontier AI models are anticipated to exceed current industry expectations, fundamentally transforming both offensive and defensive cyber capabilities," the intelligence alliance commonly known as the Five Eyes said in a three-page statement on Monday. The statement was light on detail and mostly restated core cybersecurity advice, such as swiftly patching faulty software and not putting systems online unless necessary. The officials also urged defenders to use AI "to strengthen defence", for example by identifying weaknesses sooner or responding more quickly to incidents. The warning was another indication of officials' increasing concerns over models such as Anthropic's Mythos or OpenAI's GPT-5.5-Cyber, which are said to allow users to quickly execute complex - and potentially devastating - hacks.
