How Camera Hacking Threatens Privacy and How to Protect Yourself

Monitoring systems can aid law enforcement and asset recovery, but they also pose significant privacy risks when abused.

On January 15, a netizen reported that someone had illegally cracked public cameras and uploaded the footage to Bilibili for profit, drawing attention to the misuse.

The leaked videos included recordings from teachers, hospital nurse stations, and hotel front desks.

Comments on the videos were extremely vulgar.

“This black‑market operation likely exists to lure people into paid groups; not only public cameras but also home cameras are at risk of being hacked.”

Such illegal recordings constitute serious privacy infringements and criminal behavior, including offenses related to the production, distribution, and profit from illicit content.

On January 17, Bilibili announced that it had received user reports, removed the offending videos, banned the uploading accounts, and reported the matter to authorities.

Further, on January 18 a male doctor livestreamed a gynecological surgery on Bilibili. After multiple warnings, the platform permanently banned the stream and the account.

Police in Shandong Province arrested the doctor, though the victim’s harm is irreversible.

Experts advise individuals on how to prevent illegal camera spying:

Purchase reputable brands and devices that have passed network security certifications to avoid built‑in backdoors.

Do not point cameras toward sensitive areas.

Change default passwords to strong, complex ones.

Regularly update camera firmware and associated apps.

These incidents expose gaps in platform content review and underscore the responsibility of both platforms and users to uphold legal and ethical standards.
