On the 8th, the U.S. National Security Agency (NSA), the Cybersecurity and Infrastructure Security Agency (CISA), and the Federal Bureau of Investigation (FBI) issued a joint cybersecurity advisory. They accused six Chinese artificial intelligence (AI) companies—including DeepSeek—of using “distillation” techniques to extract proprietary features and capabilities from advanced U.S. AI models on a large scale, thereby accelerating the training of their own products.
According to Reuters, the named companies include DeepSeek, Moonshot AI, and Alibaba; U.S. officials further alleged that these activities were “likely conducted with the knowledge of the Chinese government.”
