The Five Eyes intelligence alliance — comprising the US, UK, Canada, Australia and New Zealand — warned that artificial intelligence-driven cyber threats could become reality within months and called for immediate action.
In a joint statement issued on July 22, the alliance said cutting-edge frontier AI models are set to fundamentally reshape cyber capabilities on both offense and defense beyond current industry expectations.
"This paradigm shift will take place in months, not years," the statement said.
Five Eyes urged national leaders to act immediately. It called for assessments of AI-related risks, preparedness and accountability; prioritizing basic cybersecurity practices and control systems; giving cybersecurity leaders full authority and resources; and maintaining active engagement with evolving threat indicators and guidance.
The agencies added that organizations and society as a whole need to respond.
"Cyber risk is no longer just a technical issue. It is a core business risk and a leadership responsibility," the statement said.
The statement did not provide specific examples or evidence of AI-based cyberattacks.
Markets viewed the warning as an extension of broad security concerns that have persisted since the so-called "Mythos shock," which fueled fears that AI could fundamentally disrupt the existing security ecosystem.
Still, the statement carries added weight because intelligence agencies directly warned about cybersecurity threats posed by AI.
Reuters said the warning signaled that concern among global intelligence authorities over advanced AI models such as Anthropic's Mythos and OpenAI's GPT 5.5-Cyber had reached critical levels.
The statement did not name any specific model. Even so, it was widely interpreted as targeting Anthropic's Mythos, which has recently been subject to export controls.
Earlier, on July 12, Anthropic said the US government had issued export-control guidance fully blocking foreign access to Claude Mythos5 and Claude Fable5.
South Korea's government and some companies recently joined Project Glasswing, which provides access to Mythos. But the latest action by the US administration has put use of the model on hold.
