A few days ago, with the arrest of criminal suspects, the Lianyungang police spent more than 6 months of meticulous investigation, traveling more than 3,000 kilometers in Fujian, Hunan, Hebei, Shanghai and other provinces and cities, successfully smashing a criminal gang that infringed on citizens' personal information, arresting 10 criminal suspects and seizing more than 1 million yuan of funds involved in the case. After investigation, the criminal gang illegally obtained more than 4 million pieces of citizens' personal information.
Operation "Broken Card" uncovered suspicious clues
In January 2021, during the "broken card" operation in Ganyu, Lianyungang, the police found that Jia Mou, a man in the jurisdiction, had purchased a large number of unnamed telephone cards from the Internet, and after preliminary work, it was judged that he was suspected of reselling telephone cards, and this behavior was one of the main crimes combated by the "broken card" operation, so the public security organs filed a case against Jia and arrested him on January 13.
Arrest the suspect
After arriving at the case, Jia confessed to the illegal act of reselling mobile phone cards and repeatedly urged the case to be closed as soon as possible, an abnormal move that made the police handling the case perceive something unusual. After work, the police found that Jia Mou's multiple bank accounts had a huge transaction flow, and from time to time there would be accounts across the country to pay him, and his personal transfers to some fixed accounts from time to time. For the source and use of these funds, Jia Mou did not talk about it, only admitting that he sold mobile phone cards. However, the in-depth investigation of the police found that Jia had recharged more than 300,000 yuan of phone bills to different mobile phone numbers in three months, which was obviously inconsistent with the act of reselling mobile phone cards.
Subsequently, through in-depth analysis and judgment, the Ganyu police locked 6 people who had huge financial transactions with Jia, and found that they transmitted documents containing a large amount of citizens' personal information to others through QQ. "Reselling mobile phone cards, trading a large number of transactions, transmitting citizens' personal information, and various evidence shows that Jia and others are suspected of buying and selling citizens' personal information." Wang Weidong, deputy commander of the Qingkou Police Station of the Ganyu Branch of the Lianyungang Municipal Public Security Bureau, said.
A special transfer exposes "going online"
After a period of investigation, the police handling the case basically determined that all citizens' personal information was provided by Jia, and the 6 suspects locked in the early stage were All of Jia's offline. "By combing through the transaction flow of Jia's account again, we found that he used virtual currencies such as 'Huobi' and 'USDT' to make a profit, so as to evade the investigation and crackdown of the public security organs." Xu Dingyi, a network security brigade of the Ganyu Branch of the Lianyungang Municipal Public Security Bureau, said.
After locking up the identity information of the members of the criminal gang headed by Jia Mou, the Ganyu police sent a number of arrest teams to Fujian, Shanghai, Hebei and other places to carry out work, and arrested 6 suspects in one fell swoop. However, when the police combed the transaction flow of Jia's account, they found that there were thousands of accounts that had been transferred and traded with him, and at first glance there was no suspicious place, which made the investigation work deadlocked. "The more it seems that there is no problem on the surface, the more it shows that the problem is hidden deeper", the police handling the case decided to analyze and judge the transaction flow of Jia's account for the third time, and sure enough, there was a major discovery, one of the 1253 yuan transfer records made Jia's online line expose the horse's feet.
Around this special transfer record, the police decided to interrogate Jia, and Jia insisted that the transfer was transferred incorrectly. In the face of Jia's cunning argument, the police conducted an in-depth investigation of the receiving account and found that the account was owned by He, and He was a computer professional, and it is likely that he used the computer knowledge he learned to steal citizens' personal information and then sell it. In March this year, the police handling the case arrested He Mou's residence, and seized a large number of citizens' personal information and computers and other items used in the crime.
Follow the line to catch the "middleman"
After He arrived at the case, the police handling the case found that the amount of citizens' personal information he sold to Jia was significantly less than the amount that He had, and the police judged that Jia's line was more than he. Around this investigation direction, the police once again conducted in-depth analysis and judgment on the transaction flow of the two people's accounts, and found that a person named "Shui" had multiple transfer records with He, and the transaction with Jia used virtual currency.
WeChat conversations between suspects
"This person named 'Shui' should be the middleman between He and Jia, as long as they are caught, the whole case will come to light." Hu Shunyong, a police officer handling the case, analyzed. After meticulous investigation, the police locked the foothold of the intermediary "water" in Longyan City, Fujian Province, whose real identity is Guo Mou, and the police handling the case rushed to Longyan, Fujian Province, to carry out work, and arrested him on April 9. After a lot of work, the police handling the case arrested the gang member and brought him to justice.
So far, the main members of the criminal gang that infringed on citizens' personal information led by Jia, Guo, and He have all arrived at the case.
Demystify criminal gangs
It is understood that the criminal gang is divided into four levels, the first level is He Mou, who writes crawler software to steal personal information, the second level is Guo Mou, who buys and sells personal information by intermediaries, the third level is Jia Mou, who buys personal information to push fraudulent links, and the fourth level is Jia Mou.
The suspect develops a downline conversation
After investigation, Jia met Guo through the network during the resale of the calling card, learned that he could make a profit by sending sms and other ways to carry out fraud, and then became Guo's offline, and he developed a number of downlines. And Guo met He through the network, learned that he would write a web crawler software, can steal citizens' personal information from the Internet, so he reached a deal with He, purchased a large number of citizens' personal information from He's hands, and then divided personal information into online shopping, buying and selling houses, submitting resumes and other types of sent to Jia, Jia then distributed the fraudulent links and fraudulent words provided by He to the offline, and accurately pushed them to "customers" through text messages and other methods, thereby implementing fraud profits. In just a few months, the criminal gang illegally obtained more than 4 million pieces of citizens' personal information and illegally profited more than 500,000 yuan.
At present, 10 main members of the criminal gang headed by Jia, Guo and He have been taken criminal compulsory measures in accordance with law, and the case is being further tried.
