Anthropic, the artificial intelligence has disclosed that a Chinese state-sponsored hacker group manipulated its Claude AI system in order to conduct a large-scale cyber espionage campaign targeting some major corporations and government agencies worldwide. The attackers reportedly used Claude’s autonomous capabilities to execute sophisticated cyberattacks with minimal human oversight. “In mid-September 2025, we detected suspicious activity that later investigation determined to be a highly sophisticated espionage campaign.
