AI agents reportedly cut ransomware breach time from two weeks to under 10 hours
↗
A human attacker used frontier AI models to breach an enterprise network in under 10 hours, with AI agents executing each step and leaving an 80-page security audit, according to Unit 42.
This attack shows that AI agents can compress a multi-week intrusion into hours without requiring novel exploits, forcing defenders to automate their response. The incident also highlights new attack surfaces: exposed API endpoints, hard-coded tokens, and CI/CD pipelines become prime targets, and organizations must treat AI infrastructure as core assets to protect.
