Disrupting the first reported AI-orchestrated cyber espionage campaign

Anthropic detected a state-backed espionage campaign in which hackers used their Claude Code AI to autonomously carry out cyberattacks on ~30 global targets, with 80–90% of work done by AI.

Anthropic announced that it disrupted what it calls the first documented large-scale cyber-espionage campaign primarily executed by an AI system.

A Chinese state-sponsored threat actor manipulated Claude Code into acting as an autonomous cyber-operations agent by breaking malicious intent into harmless-looking subtasks.

The AI conducted reconnaissance, vulnerability scanning, exploit generation, credential harvesting, and data exfiltration with minimal human intervention, completing around 80–90% of the attack workflow. The operation targeted nearly 30 organisations worldwide. Anthropic warns that this event signals a new era in cyberwarfare, where AI agents significantly lower the skill and resource barrier for sophisticated attacks.
