The police of the Network Security Brigade of Quwo County Public Security Bureau found a simple netizen at work. He often sends messages such as guaranteed unlocking and face unlocking in QQ group. After discovering this clue, through big data analysis and judgment, it is found that netizens are naive and have close contacts with foreigners. His Alipay fund flow has a large number of payment and transfer records, and his work further proves that netizens have long naively provided illegal and smooth QQ services for overseas fraudsters. After more than half a month's investigation, the police of the task force gradually determined the true identity of the suspect, related activities, trading methods and other key information, and determined that Sun's online criminal suspects were Chongqing criminal suspect Zhang and Guangdong criminal suspect Lu. Henan criminal suspect Wang Moumou, Hebei criminal suspect Wang Moumou.
"After analysis and judgment, Sun is actually a secondary agent. Wangwang. com is an online agent and professional technical developer. Just like this person, the black industrial chain that illegally unlocked QQ accounts came into being.

After a surprise trial, all four suspects admitted the facts. If the QQ account of ordinary users is frozen, normal "unlocking" procedures can be carried out by means of face detection, SMS verification and friend guarantee. There is no need to pay extra.

Yang Qiqi, a policeman from the Internet Security Brigade of Quwo County Public Security Bureau in Shilin City, Shanxi Province, said that some of these teams specialized in QQ unlocking business were engaged in manual work, some in friend-assisted verification and some in facial recognition. The police have communicated with relevant back-end technical departments to eliminate the possibility of illegal activities from the source.
Most of them have not gone through formal channels, such as unobstructed faces. Usually, it should be a real person who makes you shake your head and open your mouth. But criminals only need a photo, which is synthesized by some related software. When you shake your head, he will rotate the photos left and right, and each photo will turn 15 degrees into 30 degrees, which is equivalent to passing the face verification, and everything else is the same.
