Anthropic published its most detailed threat intelligence report to date, covering attempted misuse of Claude across cyberattacks, influence operations, surveillance, biology, and weapons development. The standout case: Iran-linked actors used Claude to target US Navy bases, automate dossiers on Americans, and run social media influence campaigns—and reportedly uploaded their own organizational plans in the process. Anthropic says it disrupted every operation, shared findings with authorities and other AI companies, and used the lessons to strengthen safeguards.
