'Five Eyes' intelligence alliance warns new AI models pose urgent cyber risk

The 'Five Eyes' intelligence alliance, comprising the U.S., Britain, Canada, Australia, and New Zealand, has issued a stark warning about the imminent cyber threats posed by cutting-edge artificial intelligence. Officials stated that frontier AI models are poised to dramatically amplify offensive hacking capabilities, fundamentally altering both cyber offense and defense strategies. The timeline for this transformation is not years away, but mere months.

This urgent alert highlights growing concerns among officials regarding sophisticated AI models, such as Anthropic's "Mythos" and OpenAI's "GPT-5.5-Cyber." These advanced systems are reportedly capable of enabling users to execute complex and potentially devastating cyberattacks with unprecedented speed and ease.

Frontier AI models are anticipated to exceed current industry expectations, fundamentally transforming both offensive and defensive cyber capabilities. The timeline is not years, it is months.

The alliance's three-page statement, while light on specific technical details, reiterated core cybersecurity best practices. These include the critical need for rapid patching of software vulnerabilities and minimizing the online exposure of systems. Simultaneously, the officials emphasized the importance of leveraging AI itself to bolster defenses, suggesting its use in proactively identifying weaknesses and accelerating incident response times.

The warning comes in the wake of recent incidents that underscore these concerns. Earlier in June, Anthropic was compelled to disable a version of its Mythos model following a U.S. government order to suspend access for foreign nationals due to national security risks. Around the same period, the U.S. cyber defense agency CISA, a signatory to the statement, reduced the response deadlines for government officials dealing with critical digital vulnerabilities to just three days, explicitly citing the escalating threat from AI.
