Researchers Link DeepSeek to China Mobile, Banned from Doing Business in U.S.

WASHINGTON, Feb. 5, 2025 (AP) — The website of the Chinese artificial intelligence company DeepSeek, whose chatbot became the most downloaded app in the United States, has computer code that could send some user login information to a Chinese state-owned telecommunications company that has been barred from operating in the United States, security researchers say.

The web login page of DeepSeek’s chatbot contains heavily obfuscated computer script that when deciphered shows connections to computer infrastructure owned by China Mobile, a state-owned telecommunications company. The code appears to be part of the account creation and user login process for DeepSeek.

In its privacy policy, DeepSeek acknowledged storing data on servers inside the People’s Republic of China. But its chatbot appears more directly tied to the Chinese state than previously known through the link revealed by researchers to China Mobile. The U.S. has claimed there are close ties between China Mobile and the Chinese military as justification for placing limited sanctions on the company. DeepSeek and China Mobile did not respond to emails seeking comment.
