Unit 42 investigated an incident where a threat actor used frontier AI models and agentic frameworks to autonomously breach an enterprise network. The attacker compressed weeks of manual intrusion tradecraft into under 10 hours by automating reconnaissance, credential harvesting, CI/CD pipeline abuse, and cloud AI infrastructure hijacking. The attack demonstrates how AI agents can accelerate attack execution and establish redundant persistence without requiring novel zero-day exploits.
