What happened

South Korean cybersecurity researchers found that DeepSeek shared user data with third parties. In early February, researchers identified a script on DeepSeek's website that collected account creation and login information and sent it to China Mobile, a Chinese state telecommunications company.

The South Korea Personal Information Protection Commission (PIPC) confirmed that DeepSeek communicates with ByteDance, the parent company of TikTok. A PIPC spokesman stated: 'We confirmed that DeepSeek communicates with ByteDance,' and added that the agency 'still needs to determine which data was transferred and to what extent.'

Reported impact

The data sharing raised privacy concerns about the artificial intelligence company. The reason for DeepSeek sharing user data with ByteDance remains unclear.

Governance controls

The PIPC previously halted new downloads of DeepSeek's mobile applications due to privacy violations. South Korea removed DeepSeek from app stores.
