Why it matters
The advisory signals that adversarial model-distillation and capability extraction against deployed LLMs is being treated as a nation-state-scale threat, raising the stakes for how AI providers monitor and defend against systematic API-based extraction.
A joint NSA, CISA, and FBI advisory (AA26-251A, released Sept. 8, 2026) accuses China-based AI firms of conducting industrial-scale knowledge distillation campaigns to covertly extract restricted proprietary functionalities from U.S. frontier models. The agencies allege companies including Alibaba, DeepSeek, MiniMax, Moonshot AI, StepFun, and Z.AI extracted billions of tokens across millions of requests from variants of Claude, GPT, Gemini, and Grok since at least late 2024.
