After the incident, the public security organs made every effort to find out the situation of telecommunication network fraud gangs and the source of information leakage. After investigation, the criminal suspect Du Mou used technical means to attack "Shandong 20 16 College Entrance Examination Online Registration Information System", implanted Trojan virus in the website, gained the backstage login authority of the website, and stole a large number of candidates' registration information, including Xu Yuyu.
In early July, the suspect Chen Mou rented a house in Jiujiang City, Jiangxi Province, and set up a fraud den. After searching for chat groups such as "College Entrance Examination Data Group" and "Student Data Group" through QQ, I posted my personal information purchase demand in the group, and bought 1.8 million pieces of high school graduates' data from Du Mou at the price of each 0.5 yuan. At the same time, Zheng, Huang and others were hired to pretend to be the staff of the Education Bureau and the Finance Bureau to make phone calls in the name of granting scholarships to students enrolled in the college entrance examination.
At about 6: 00 on August 9/kloc-0, the gang defrauded Xu Yuyu of 9900 yuan. Six minutes after remitting money to the bank card account opened by the criminal suspect using someone else's ID card, Chen Mou manipulated the criminal suspect Zheng Moumou in Quanzhou, Fujian Province to organize Xiong Mou, Chen Moumou and others to go to the ATM of a bank in Quanzhou to collect the stolen money. The public security organs further found out that the criminal suspect Mou Peng had repeatedly sold mobile phone cards without real names to criminal gangs in Chen Mou through the Internet for use by criminal gangs. At present, the above eight suspects have been arrested.
