TL;DR: Unit 42 just proved that autonomous AI agents can execute full cloud attack chains—from recon to exfiltration—in under 3 minutes. The research was done on GCP, but the lessons are universal. If you're running on AWS, here's what you need to know. The Moment AI Stopped Being Theoretical In November 2025, Anthropic dropped a bombshell: a state-sponsored espionage campaign where AI didn't just assist human operators—it became the operator, autonomously handling 80-90% of the attack . That shifted the conversation from "could this happen?" to "this is happening." To understand exactly what current LLMs are capable of, Palo Alto Networks' Unit 42 built Zealot—a multi-agent AI penetration testing system—and let it loose in a live cloud environment. The results are a wake-up call for anyone running infrastructure in the cloud . Meet Zealot: A Multi-Agent Offensive System Zealot isn't a single AI.…
