Five Eyes Warn AI-Driven Cyber Threats Could Materialize Within Months

Bitcoin BTC Five Eyes, the intelligence-sharing alliance of the US, UK, Canada, Australia and New Zealand, warned that cyber threats stemming from artificial intelligence could materialize within months and called for immediate action.

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

Reuters Says Warning Signals Intelligence Concerns Over Models Such as Anthropic's Mythos and OpenAI's GPT 5.5-Cyber

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

In a joint statement issued on July 22, the group said frontier AI models are set to fundamentally reshape cyber capabilities in both attack and defense beyond current industry expectations. The shift, it said, would come in months, not years.

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 staying actively engaged with evolving threat indicators and guidance.

The agencies said organizations and society as a whole must respond. Cyber risk is no longer merely a technical issue. It is a core business risk and a leadership responsibility.

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

Markets have viewed the warning as an extension of broad security concerns raised 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 AI-driven cybersecurity threats.

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 a critical level.

The statement did not name any specific model, though it is widely interpreted as targeting Anthropic's Mythos, which has recently been hit by 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.
