Unsecured Police Dashboard Exposes Extensive Surveillance of Foreigners in China

A cybersecurity researcher has uncovered an unsecured police dashboard that provides a rare, transparent look into the sophisticated methods China uses to monitor foreign nationals. The platform, identified as the “Dynamic Control Platform for Overseas Personnel,” was discovered by Marc Hofer, an Amsterdam-based researcher and journalist, while he was investigating state surveillance practices. The system, which appeared to be in a testing phase for the Zhangjiakou Public Security Bureau, functioned as a centralized hub for tracking individuals in the city that co-hosted the 2022 Winter Olympics.

The database contained records for nearly 12,000 people, including over 700 foreign residents and more than 300 foreign journalists. The scope of the data collection is significant, as the system aggregated information from various sources to build comprehensive profiles. These profiles included official passport photographs, visa details, personal cellphone numbers, and travel history. In some instances, the system even incorporated data from facial-recognition cameras at local ski resorts, medical records, and transit information such as train seat numbers.

For many, the discovery was deeply personal. Hofer reported finding his own profile within the system, complete with an immigration photograph and private contact details. The dashboard’s design, which users compared to the futuristic interface of the film Minority Report, allowed authorities to monitor the movements and activities of foreigners in real-time. The inclusion of individuals from Hong Kong and Taiwan, alongside foreign nationals, highlights the broad reach of Chinese state surveillance.

Security experts note that while the existence of such surveillance is often suspected, this leak offers concrete evidence of how authorities synthesize disparate data points into a unified tracking tool. The fact that the dashboard was left accessible on the open web—with login credentials already populated—underscores potential vulnerabilities in the infrastructure supporting these massive data-gathering operations. As of now, the incident serves as a stark reminder of the unprecedented scale of digital monitoring faced by those living in or traveling through China.
