Google says it stopped a mass cyberattack after AI was used to discover a zero-day exploit

Google says it stopped a planned mass cyberattack after an attacker used AI to find and weaponize a zero-day vulnerability.

Its threat team also found state-backed and criminal groups using AI for vulnerability research, malware creation, and supply-chain targeting.

The report cites activity tied to China-, North Korea-, and Russia-linked actors, showing AI is speeding up offensive cyber operations.

Google highlighted tools and efforts like Big Sleep and CodeMender as examples of AI also being used for defense.
