DeepSeek represents a profound threat to our nation’s security. Although it presents itself as just another AI chatbot, offering users a way to generate text and answer questions, closer inspection reveals that the app siphons data back to the People’s Republic of China (PRC), creates security vulnerabilities for its users, and relies on a model that covertly censors and manipulates information pursuant to Chinese law. Equally troubling, the model appears to have been built using stolen U.S. technology on the back of U.S. semiconductor chips that are prohibited from sale to China without an export license and when it was released, PRC-affiliated social media accounts amplified and celebrated the model, according to Graphika research. This report documents some of the risks DeepSeek poses and explains how its development is based on common Chinese Communist Party (CCP) tactics designed to unlawfully undermine U.S. technological leadership and critical American policies to protect national security.
