According to the Shenzhen Financial News, the hacker named "Guardian K" (Note: the previous live KYC accounts for "Guardian M" and "Guardian J" respectively) once again broadcast the currency KYC data in the telegraph group. A total of 42 sets of personally identifiable information were announced. The date of KYC certification was February 27, 2018. The KYC dates published in the first two live broadcasts were February 24, 2018 and February 26, respectively.
