U.S. agencies accuse six Chinese AI firms of industrial-scale model extraction
A joint NSA, FBI, and CISA advisory says six China-based AI companies extracted billions of tokens from U.S. frontier models across millions of exchanges since at least late 2024. It names DeepSeek, Moonshot AI, Alibaba, MiniMax, StepFun, and Z.AI, and says the campaigns targeted variants of Claude, GPT, Gemini, and Grok. Knowledge distillation itself is a legitimate training technique. The agencies describe these campaigns as malicious because they allegedly used fraudulent accounts, regional workarounds, bulk subscriptions, third-party aggregators, gray-market transfer stations, metadata sanitization, prompt injection, and automated quality checks to violate access restrictions and reproduce proprietary capabilities at scale. The advisory's most useful contribution is operational: monitor nonstop usage, immediate maximum activity from new accounts, shared identities, similar prompts across providers, and coordinated failover when one pathway is blocked. It recommends targeted response changes and cross-company intelligence sharing. Its largest claims still require careful labeling. The document does not publish the underlying intelligence for every attribution, and its statement that activity occurred likely with Chinese government awareness is an official assessment rather than independently inspectable proof. The policy risk is overcorrecting by treating all distillation or cross-border research as theft. The better response is behavioral: detect coordinated extraction, preserve evidence, enforce terms consistently, and establish a protected process for independent review of consequential attribution.
