AI company Anthropic recently announced that companies worldwide have been attacked by an AI-powered cyber espionage campaign. It is purported to be the first publicly documented case of a cyberattack carried out by an AI model.
According to the research report, around 30 organizations worldwide were affected by the attacks. These included large technology companies, financial institutions, chemical companies, and government agencies. The attack was discovered in mid-September 2025. The hacking group GTG-1002, which is linked to China, is said to be behind the attack campaign.
The attackers allegedly manipulated Anthropic’s AI programming tool Claude Code to launch largely autonomous infiltration attempts, according to Anthropic’s report.
