The Five Eyes intelligence alliance — comprising the United States, Britain, Canada, Australia and New Zealand — issued a joint statement on Monday warning that advanced artificial intelligence (AI) models could significantly boost cyberattack capabilities. In a three-page declaration, the alliance stressed: 'Advanced AI models are projected to surpass current industry expectations, fundamentally altering both offensive and defensive capabilities in cyberspace.'
Officials said the window to adapt to this threat is 'not years, but months.' The statement also urged defenders to deploy AI to 'enhance protections,' such as earlier detection of weaknesses or faster incident response.
While the statement lacked specific details and largely reiterated basic cybersecurity recommendations (such as timely software patching and not connecting systems to the internet unnecessarily), it signals growing concern over models like Anthropic's Mythos and OpenAI's GPT-5.5-Cyber, which are said to enable users to carry out sophisticated, potentially devastating hacks.
Earlier this month, Anthropic was forced to disable a version of Mythos after the US government demanded that access to foreign nationals be suspended due to national security concerns. Around the same time, the US Cybersecurity and Infrastructure Security Agency (CISA) — one of the signatories to Monday's statement — shortened the deadline for government officials to address critical digital vulnerabilities to three days, citing the AI threat.
