On March 3, 2021, the case was sentenced in a centralized way. Zhang and other eight defendants made an illegal profit of more than 2 million yuan by brushing the reading volume and selling wechat group chat QR code. They were convicted of the crime of illegally obtaining computer information system data and controlling computer information system.
However, after obtaining the control authority of wechat account, the criminals take the opportunity to illegally obtain the user's wechat group chat QR code information, and store these group chat QR codes in the form of pictures on the server, and then sell them to downstream criminal gangs such as fraud and gambling to make profits.
Since February 2020, strangers frequently scan code into groups, spread illegal advertisements such as gambling and marketing, and even implement fraud. There are more than 1500 related cases involving more than 20 provinces and cities.
According to Tencent's feedback, after the leakage of wechat group chat QR code, they cooperated with many local public security organs in accordance with the law and arrested a number of criminal gangs who sold and used wechat group chat QR code to commit crimes.
In just 3 months, the criminal gang illegally obtained 2000 million WeChat users' chat codes, which were sold to fraud and gambling criminal groups in Longyan, Fujian and other places. At the same time, they paid attention to WeChat official account and brush reading volume and brushes for others, and made a profit of over 200 yuan.
