Five Eyes Warn AI-Driven Cyber Threats Could Become Reality Within Months

Five Eyes Statement Warns of Technological Paradigm Shift From AI

"Cyber Risk Is a Core Business Risk and a Leadership Responsibility"

Reuters Says Warning Signals Intelligence Concerns Over Anthropic and OpenAI

The Five Eyes intelligence alliance of the US, UK, Canada, Australia and New Zealand warned that cybersecurity threats driven by artificial intelligence could become reality within months and called for immediate action.

In a joint statement issued on July 22, the alliance said frontier AI models are set to fundamentally reshape cyber capabilities in both attack and defense beyond current industry expectations.

"That paradigm shift will take place in months, not years," it said.

The 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 intelligence agencies said the response must extend across organizations and society as a whole.

"Cyber risk is no longer merely a technical issue. It is a core business risk and a leadership responsibility," the statement said.

The statement did not provide specific evidence or examples of AI-based cyberattacks.

Markets have viewed the warning as an extension of broad security concerns that have persisted since the so-called "Mythos shock," which raised fears that AI could fundamentally disrupt the existing security ecosystem.

Still, the warning carries added weight because intelligence agencies directly addressed cybersecurity threats posed by AI.

Reuters said the statement signals that concerns among global intelligence authorities over advanced AI models such as Anthropic's Mythos and OpenAI's GPT 5.5-Cyber have reached a critical level.

The statement did not name any specific model, though it is widely seen as aimed at Anthropic's Mythos, which has recently been subjected to export controls.

Anthropic said on July 12 that the US government had issued export-control guidance fully blocking foreign access to Claude Mythos 5 and Claude Fable 5.

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.
