Investigation into Data Black Market
The Cyber Security Law of China, which came into force June 1, 2017, stipulates that obtaining or selling more than 50 pieces of personal information illegally is criminal behavior. Available statistics show that about 5.53 billion pieces of personal information, or an average of four pieces per person, have been leaked in China. Among them, 80 percent of data were leaked by company insiders; while just 20 percent were leaked by hackers.
However, our investigation reveals that a lot of channels for underground data transactions remained after the implementation of the Cyber Security Law. The daily transaction volume of this “underground black network” could reach up to 100 million yuan, while its overall size is hard to estimate. Some data companies even received massive funding and became star start-ups.
