Anthropic alleges mass Claude distillation by Chinese AI labs amid Pentagon blacklist fight

Anthropic alleged that three China-based AI labs—DeepSeek, Moonshot AI, and MiniMax—used roughly 24,000 fraudulent accounts to generate more than 16 million interactions with Claude in a coordinated effort to extract the model’s advanced reasoning, coding, and tool-use capabilities. The company said it linked the activity through IP correlations, request metadata, and infrastructure indicators, and warned that large-scale unauthorized distillation could remove safety guardrails and enable copied capabilities to be used in offensive cyber operations, disinformation, intelligence collection, and mass surveillance. Anthropic said it shared its findings with U.S. government entities and industry partners, while noting it had no evidence that the Chinese government directly coordinated the campaigns.

The allegations surfaced as Anthropic remains in a separate high-stakes dispute with the U.S. Department of Defense, which on June 4 refused to reverse the company’s designation as a supply-chain risk. Anthropic is challenging the Pentagon’s March blacklisting after Defense Secretary Pete Hegseth invoked emergency powers following failed talks over limits on Claude’s use for domestic surveillance and autonomous weapons. Federal attorneys told the court the procedural dispute over administrative remedies is now moot because the secretary has denied reconsideration, and reporting indicates a majority of the appellate panel appeared inclined to let the designation stand while the case proceeds.
