Anthropic says Claude AI used to build missiles, hunt Uyghurs and spy on phones
Anthropic has released a detailed threat intelligence report documenting how its Claude AI models were misused by state-sponsored actors and criminals for activities like weapons development and cyber espionage. The report highlights specific instances of misuse, including the tracking of US naval forces, and details the company's efforts to mitigate these risks.
Why it matters
This report provides unprecedented transparency into the real-world security risks posed by generative AI, moving the debate beyond theoretical extinction scenarios to immediate national security concerns.
Anthropic has published its most detailed threat intelligence report so far, and the picture it paints of how its Claude models are being misused is far less abstract than the extinction argument currently dominating the AI debate. Over eight months, from December 2025 to August 2026, the company says it identified and shut down operations in which suspected state-sponsored spies, weapons engineers, commercial spyware vendors, propaganda outfits and ordinary criminals used Claude for work that until recently needed trained teams. The report spans seven categories of harm: cyber operations, influence operations, surveillance, scams and fraud, biological misuse, conventional weapons development and unauthorised model distillation.The cases involved Claude Haiku, Sonnet and Opus models. Anthropic says none of the misuse it found ran on its Fable or Mythos class models, with one exception in the distillation section.
