Satellite surveillance: China cautions public about unwittingly leaking secrets

China's Ministry of State Security issued an online warning on Sunday, urging citizens to be cautious about sharing information that could be exploited by foreign intelligence agencies. The statement highlights the increasing use of space-based technology for espionage, with foreign actors leveraging remote sensing satellites to conduct real-time surveillance of China.

The MSS emphasizes the growing use of outer space for intelligence gathering. Foreign intelligence agencies are reportedly employing high-precision remote sensing satellites for continuous monitoring of China. These efforts are allegedly bolstered by data analysis from professionals and even unsuspecting netizens.

The MSS cautions against the inadvertent sharing of sensitive information online. Examples include uploading photos of sensitive areas, particularly military installations, to map applications. Additionally, the statement discourages public discussions on social media platforms concerning military matters and classified information.

The MSS highlights cases where individuals, motivated by curiosity or a desire to showcase expertise, analyze satellite imagery of military locations, discussing details such as equipment models and construction progress. This type of online commentary, the MSS warns, can provide valuable clues to foreign intelligence agencies.

The statement also reveals instances of foreign agents recruiting collaborators within China to install illegal spyware detection devices near airports, ports, and military bases. These devices can reportedly transmit stolen data directly to foreign spy satellites, posing a significant national security risk.

The Ministry of State Security urges citizens to prioritize national security awareness. They advise against taking or uploading pictures of sensitive areas and discourage public discussions of military matters on social media. The MSS encourages immediate reporting of any suspicious activity, including offers for free device installations or data sharing arrangements.
