Five Eyes Warn AI Is Accelerating Cyber Threats and Shrinking Response Time

The Five Eyes cyber security agencies issued a joint warning that artificial intelligence is rapidly increasing the speed, scale, and sophistication of cyber threats across governments, businesses, and critical infrastructure. The statement said AI is shortening the gap between vulnerability discovery and exploitation, enabling attackers to automate operations and expand campaigns more efficiently, while also giving defenders new tools for detection and response. Officials said cyber resilience must now be treated as a core business and leadership responsibility tied to operational continuity, market trust, and long-term value.

The agencies urged organizations to act immediately on foundational controls, including reducing attack surface, accelerating patching, replacing or isolating legacy and unsupported systems, and strengthening identity and access management. They also called for secure-by-design, secure-by-default, and defence in depth practices, along with stronger incident response and recovery planning to prepare for inevitable breaches. At the same time, the advisory encouraged deliberate use of AI in security operations for anomaly detection, vulnerability management, and faster response, while stressing that effective resilience will require executive oversight, vendor accountability, and sustained public-private collaboration.
