Spy agencies from the Five Eyes intelligence alliance have warned that frontier AI could transform cyber offence and defence in months, not years, according to a joint statement released on 22 June 2026. The agencies said the rapid pace of frontier AI development means cyber-risk assumptions can become outdated quickly, and urged organisations to treat cyber resilience as a core business priority rather than a narrow technical concern.
The statement says AI is already increasing the speed, scale and sophistication of cyber threats, while also offering defensive benefits if organisations have strong security practices in place. It calls on leaders to understand and assess risk, prioritise foundational cyber-security controls, empower cyber leaders with authority and resources, and keep adapting as threats evolve.
