The Five Eyes intelligence alliance, comprising the US, UK, Canada, Australia, and New Zealand, has issued a joint statement warning that advanced AI models will significantly enhance offensive hacking capabilities within months.

According to Al Jazeera, Reuters, and The Guardian, the alliance stated that 'Frontier AI models are anticipated to exceed current industry expectations, fundamentally transforming both offensive and defensive cyber capabilities.' The statement emphasizes the urgency of the situation, noting that the timeline for these changes is measured in months rather than years.

While the statement was light on specific details, it reiterated core cybersecurity advice such as swiftly patching faulty software and avoiding unnecessary system exposure. Officials also encouraged defenders to leverage AI to identify vulnerabilities sooner and respond more quickly to incidents.

The warning highlights growing concerns over models like Anthropic’s Mythos and OpenAI’s GPT-5.5-Cyber, which are said to enable users to execute complex and potentially devastating hacks rapidly. Earlier this month, as reported by Reuters, Anthropic was forced to disable a version of Mythos after the US government ordered it to suspend access for foreign nationals due to national security concerns.

The statement comes amidst broader actions taken in response to AI threats. As noted by The Guardian, the US cyber-defense agency, CISA, reduced deadlines for government officials to address serious digital vulnerabilities in their networks to three days, citing AI-related risks. The Five Eyes alliance underscored that cyber resilience is crucial for business continuity and market confidence.
