  After further investigation by the ad hoc group, the Nantong police found that since May 2019, "akula98" has repeatedly sold personal information of citizens through the "dark web" trading platform, a large number.

  However, the “cracknet” can provide the task force with only one user name. The true identity of the suspect is unknown, and the case investigation stalemate is at a standstill.

  Under the leadership of Xu Pingnan, the project team built its own data model and, through in-depth research and judgment, locked the real identity of "akula98" as Wang Moucheng in Ningbo, Zhejiang.

  On the evening of September 9, 2019, the police of the task force captured Wang Moucheng and successfully extracted the Bitcoin trading app and the network disk used to store the personal information of citizens on his mobile phone.

  According to Wang Moucheng, he collected a large amount of business information through various channels, and illegally purchased personal personal information data including futures and foreign exchange investors, and sold it on the "darknet" trading platform.

The case is significant, and the case was subsequently listed as a case supervised by the Ministry of Public Security.
