A state-backed threat group, likely Chinese, crossed a threshold in September that cybersecurity experts have warned about for years. According to a report by Anthropic, attackers manipulated its AI system, Claude Code, to conduct what appears to be the first large-scale espionage operation executed primarily by artificial intelligence. The report states “with high confidence” that China was behind the attack. AI carried out 80% to 90% of the tactical operations independently, from reconnaissance to data extraction. This espionage campaign targeted roughly 30 entities across the U.S. and allied nations, with Anthropic validating “a handful of successful intrusions” into “major technology corporations and government agencies.”

Full commentary : With basic tech and little human oversight, Chinese spies apparently exploited Anthropic’s Claude Code.
