What changed
Leaders of the Five Eyes cybersecurity agencies warned that frontier models could rapidly transform offensive and defensive cyber capabilities, saying the relevant timeline is months rather than years.
Why it matters
The warning places patching, identity, resilience, and AI-enabled defense on an immediate operating timeline rather than a long-term policy horizon.
What to do
Reduce patch latency, inventory exposed systems, strengthen identity controls, and test AI-assisted defensive workflows before more capable offensive tooling spreads.
Caveat
The statement is a strategic assessment and does not disclose model evaluations, attack data, or probabilities behind its timeline.
