In a groundbreaking event, an autonomous AI agent system executed a full-scale cyber operation, marking a significant departure from previous incidents. This operation was driven entirely by an AI framework, which conducted thousands of independent actions within a cluster of short-lived sandbox environments. The command and control (C2) servers were self-deployed on public services, aligning with the predicted "agentic attacker" scenario in the industry. The incident highlighted the "asymmetry problem" in cybersecurity. Initial attempts to analyze logs using commercial API models were thwarted by security guardrails, which could not differentiate between responders and attackers. Consequently, the team switched to using GLM 5.2 on their infrastructure for forensic analysis, ensuring that no attacker data or credentials left their environment.
