Hacker Claims to Have Stolen Data of a Billion Chinese Citizens From Police Database

A hacker has claimed to have procured a trove of personal information from the Shanghai police on 1 billion Chinese citizens, which tech experts say, if true, would be one of the biggest data breaches in history.

The claim of a hack comes as China has vowed to improve protection of online user data privacy, instructing its tech giants to ensure safer storage after public complaints about mismanagement and misuse.
