The Five Eyes intelligence alliance—comprising the United States, United Kingdom, 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 light on specific details, the warning 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 alliance underscored that cyber resilience is crucial for business continuity and market confidence.

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 urged governments and businesses to act swiftly to prepare themselves as AI evolves.

According to CBS News, the rapid pace of frontier AI development means cyber risk assumptions can become outdated in months, not years. The advisory from the Five Eyes highlighted that AI 'lowers barriers for malicious actors and increases the speed and complexity of attacks.' To improve cyber defenses, organizations should integrate AI tools into their security operations, update old systems, and limit access to critical systems among other steps.
