Xu Yuyu's telecom fraud case deceived Xu Yuyu, a prospective college student in Linyi, Shandong Province, of all her tuition fees and also deceived this 18-year-old girl of her young life. Recently, under the unified command of the Ministry of Public Security, all eight suspects involved in the case were brought to justice. CCTV reporters interviewed the suspects of the fraud. When the scammer completely restored the fraud, the reporter found that Xu Yuyu's unfortunate death exposed the gaps and black holes that were still opening behind the telecom fraud. Xu Yuyu called the police during his lifetime: Hello, hello, this afternoon, there was a person who called and said that it was from the Education Bureau and asked me to call another telephone number. He said that it was the Ministry of Finance and said it was a scholarship. He asked me to contact this person, and then he gave me a phone number and asked me to call that phone number. After I called... On the afternoon of August 19, 2016, a phone call to home made Xu Yuyu very happy. Xu Yuyu, who lives in Linyi, Shandong Province, was admitted to Nanjing University of Posts and Telecommunications this year. Due to family difficulties, she applied for a scholarship from the education department. This call informed her that she would receive the scholarship immediately. Xu Yuyu's mother: Mom, I have to go to the bank. I said, why are you going to the bank? She said she got me a scholarship of 2600 yuan, but I said it was from the Education Bureau. The mother and daughter would never have imagined that this call from a staff member of the Education Bureau was from Jiujiang, Jiangxi. That afternoon, the person who made the call was named Zheng Xiancong. Suspect Zheng Xiancong: I told her that I am from a certain Education Bureau and have a student scholarship. "Role" plays gang members to carry out precise fraud Zheng Xiancong, 26, from Yongchun County, Quanzhou City, Fujian Province, dropped out of school when he was in the fourth grade of primary school. He was a front-line member of the telecommunications fraud gang. His role in this scam was to pretend to be a staff member of the Education Bureau. Suspect Zheng Xiancong: I told her there was a scholarship. You had a student scholarship of 2680. If you want to collect it, today is the last day. You have to contact the staff of the Financial Bureau. When Xu Yuyu called according to the number of the Finance Bureau provided by the other party, the person who answered the call was a second-line person of the fraud gang. Also in a rental house in Jiujiang, Jiangxi Province, Chen Wenhui, who pretended to be a staff member of the Finance Bureau, started a conversation with Xu Yuyu. Reporter: How many phone calls did you make that day? Suspect Chen Wenhui: There should have been one or two hundred hits that day, two or three hundred. Reporter: How many people were you successfully cheated of money that day? Suspect Chen Wenhui: There is only one. Reporter: There is only Xu Yuyu. Suspect Chen Wenhui: Yes. Chen Wenhui, 22 years old, from Anxi County, Fuzhou City, Fujian Province, dropped out of school in his first year of junior high school. He was the main organizer of the fraud gang. As a second-line employee, his role was to pretend to be a staff member of the Finance Bureau. This was also the most critical part of the entire fraud, to trick the other party into sending money. Suspect Chen Wenhui: I just asked her to go to the bank to check if the subsidy had arrived, and then to check how much money was on her card. On that afternoon with heavy rain, Xu Yuyu braved the rain to a nearby bank. On the other side of the phone, Chen Wenhui began to implement the most important step of the entire scam, deceiving Xu Yuyu to remit money in the name of activating her account. Suspect Chen Wenhui: I told her that the card needs to be activated and she needs to be activated through this deposit machine. Chen Wenhui asked Xu Yuyu to withdraw the full amount of the bank card containing tuition fees, and then deposit the cash into the scholarship account he designated for activation. The surveillance probe in front of the ATM left Xu Yuyu's last image. At about 17:30 pm that day, Xu Yuyu took out 9900 yuan in tuition fees and then deposited all of them into the bank account sent by the scammer. Reporter: How can you call her this number and she will believe it? Suspect Chen Wenhui: When Zheng Xiancong called, he told her what her name was, then which school she studied in, and then what her parents 'names were. Xu Yuyu was convinced by phone that she had sent a special person to withdraw money. Until she left this world, the 18-year-old girl did not know that her personal information had been stolen and resold. Just as she was anxiously waiting in the rain for student remittances, at an ATM in Quanzhou, Fujian, someone had taken out all her 9900 yuan tuition fees. Chen Wenhui called his Quanzhou partner Zheng Jinfeng, who arranged for Xiong Chao, who was specially responsible for withdrawing money, to withdraw the money and divide the stolen money. Suspect Xiong Chao: Zheng Jinfeng said that there is a number, 628, Agricultural Bank of China, 10,000, which is almost what it means. Reporter: What does this sentence mean? Suspect Xiong Chao: In the number 628, the Agricultural Bank received 10,000 yuan and asked me to get it. Without waiting for a reply, Xu Yuyu called back the other party's phone number, only to find that the other party had turned off the phone. At this time, Xu Yuyu realized that she might have encountered a scammer and that the 9900 yuan tuition fee remitted was just collected by her parents the day before. Xu Yuyu's mother: Dad, let's report the case. His father said he wouldn't report the case. What kind of case would it cost 10,000 yuan. Yuyu said that I was in great pain. Dad, let's report the case, but he still cried and refused to eat. Xu Yuyu's father: She usually doesn't want to spend some money. Sometimes she can't spend 100 yuan for two weeks at school. If she gives her more, she doesn't want it. It's not easy for her to make money at home. At Xu Yuyu's insistence, her father accompanied her to the police station overnight to report the police. Xu Yuyu's father: She collapsed after walking out of the police station for less than three minutes. 120 arrived and took a look, saying that it had been too long. When he arrived at the hospital for a check-up, his heart stopped. At 9 o'clock that night, the 18-year-old girl failed to enter the university she dreamed of and left this world forever. After the incident, the Ministry of Public Security organized police in Shandong, Fujian, Guangdong, Sichuan and other places to jointly investigate and pursue, and successively arrested criminal suspects Chen Fudi, Zheng Jinfeng, Huang Jinchun, and Xiong Chao. The criminal suspects Chen Wenhui and Zheng Xiancong voluntarily surrendered after the Ministry of Public Security issued an A-level wanted warrant. Within one month, the police initially verified that five of the six suspects were from Quanzhou, Fujian. Chen Wenhui, Huang Jinchun and Zheng Xiancong pretended to be staff members of the Education Bureau and the Finance Bureau in Jiujiang, Jiangxi to make fraudulent calls. Zheng Jinfeng organized Chen Fudi and Xiong Chao in Quanzhou, Fujian to withdraw money and share the stolen goods. Starting from August 2016, within a month, six people used scholarship fraud to defraud a total of more than 30,000 yuan, the largest being 9900 yuan in Xu Yuyu's case. Chen Wenhui, the main organizer of the fraud gang who found fraud scripts online and bought virtual numbers, dropped out of school at the age of 15 and left his hometown of Anxi to go out to work. At the beginning of this year, Chen Wenhui found a script online to defraud students in the name of scholarships and wanted to implement telecommunications fraud. There are also two indispensable tools for committing crimes, one is a telephone card and the other is a bank card, and neither of these cards cannot be processed under real names. For the phone card, Chen Wenhui chose the virtual number segment starting with 171. Reporter: Do you need to show your ID card to buy 171 and 170 phone cards? Suspect Chen Wenhui: No. Reporter: Can I buy it as long as I transfer money? Suspect Chen Wenhui: Yes. Reporter: How many of these phone cards have you bought? Suspect Chen Wenhui: More than a dozen, Unicom bought more than a dozen, and then 171 also seemed to buy seven or eight, six or seven. Reporter: Do you know who the person who sold you the phone card is? Suspect Chen Wenhui: I don't know. Buying a non-real-name bank card and a non-real-name phone card in the QQ group hides the true identity of the scammer. Once the fraud is successful, a non-real-name bank card needs to be used to withdraw cash. Chen Wenhui said that non-real-name bank cards, like telephone cards, can also be purchased online. Reporter: Where can I sell it? Suspect Chen Wenhui: He is in the group. Reporter: What group? Suspect Chen Wenhui: In the QQ group, the police traced the bank card that the suspect used to withdraw Xu Yuyu's tuition fee of 9900 yuan. It was found that the account holder of the card was from Anhui. It was not until the police found it that he knew that his identity had been falsely used by others and the card was opened. Wang Ju, captain of the Criminal Police Brigade of Luozhuang Branch of Linyi City Public Security Bureau: The account holder said that he lost his ID card when working in Guangdong two years ago. The bank card was issued after his ID card was lost. Non-real-name bank cards are exclusively used for money laundering and fraud. According to cases cracked in recent years, the police found that using other people's ID cards to resell bank cards has become a black industry chain. Most of these non-real-name bank cards are exclusively used for money laundering and fraud crimes. Buying a non-real-name phone card and bank card is only the basic condition for fraud. The most critical part is the most critical part for fraud to succeed, and that is the personal information of the fraud target. Precise fraud is a key move for all types of telecommunications fraud to succeed. If you want accurate fraud, you must have accurate personal information. Xu Yuyu believed the other party's identity precisely because the other party could accurately tell her name, address and school. The criminal suspect confessed that Xu Yuyu's personal information was also purchased online. Suspect Zheng Jinfeng: I bought it through QQ. Reporter: What kind of information does it sell? Suspect Zheng Jinfeng: I know of those who sell student information, as well as those who sell car owners and house purchases. Reporter: In terms of price? Suspect Zheng Jinfeng: Student personal information is relatively cheap, a few cents. Student information is the cheapest to buy online without difficulty. Police initially verified that since June this year, the criminal suspect Chen Wenhui has illegally purchased tens of thousands of personal information of Shandong college entrance examination candidates on the Internet, mainly from Linyi, Shandong. The information includes the student's name, school, home address and contact phone number. The chief offender Chen Wenhui said that he chose to target students because students had the cheapest information and the lowest cost, and there was almost no difficulty in purchasing personal information online. Reporter: What social software does this group use? Suspect Zheng Jinfeng: QQ. Reporter: How do you know you can find these in QQ? Suspect Zheng Jinfeng: I was just playing casually at that time. Aren't there many such scams in my hometown of Anxi? Also, I wanted to try it. From "blind fraud" to "precise fraud", who is the QQ group mentioned many times by the criminal suspect of stealing information, is there really a "black market" for selling personal information hidden? The reporter entered "data trading" and "first-hand data" in the QQ group search column to search, and hundreds of QQ groups appeared. Most of the comments of these groups are marked with "data trading, data purchase","material washing, material interception, data transaction". The reporter applied to join several groups and was quickly approved. In these QQ groups, citizens 'personal information is called "data" and "materials". Various private information is openly released within the group, clearly marked, and is called to be bought and sold. The person with the online name "Dabaojian" released information saying that there are all kinds of data available from banks, credit cards, elderly health care, online shopping, and electronic shopping, and also sold packaged data from 2015 to 2016. A person with the online name of Qiyou posted information saying that bank data and personal data cost 100 yuan to pack 10,000 pieces. The "Information Black Market" sells a full set of personal information for three yuan. A person named "Integrity Data" took the initiative to sell information on car owners to reporters. Luxury car owners are priced at 400 yuan and 10,000 pieces of information, and ordinary car owners are priced at 300 yuan and 10,000 pieces of information. In order to prove its "integrity","Integrity Data" took the initiative to send multiple pieces of vehicle owner information to reporters for inspection, including the owner's name, license plate number, mobile phone number, frame number, and engine number. After calling the mobile phones of these car owners, the reporter found that all the information was true. This person claimed that he also sold a full set of personal information, from a copy of his ID card, family members, a copy of his household registration book, to online account names. The price of the full set of information was 3 yuan per set. Browsing these QQ groups, you can find that citizens 'personal financial information is a hot commodity for information traffickers. A person with the online name "Fengchi" directly sold bank depositor information, including the citizen's bank account name, card number, ID card, password, and mobile phone number. He also specifically stated that it was the latest data from September this year and knew the balance in the account. Beijing: 160 million pieces of personal information have been leaked in six years. The latest survey data shows that the Beijing District Court alone confirmed that as many as 160 million pieces of personal information have been leaked from 2010 to 2016. Hao Zhichao, director of the Report Acceptance Center of the Internet Society of China: The disclosure of personal information is very serious. We have designed a set of questionnaires, which includes a survey: Do you feel the impact of the disclosure of personal information on you? The results show that 84% of netizens have personally felt the impact of the disclosure of personal information. Investigate how the source of the information leaked and how the suspect's "special" personal information fell into the hands of others? How was originally private personal information leaked? Police launched an investigation into the source of Xu Yuyu's personal information leakage. Relevant clues show that the person who sold examinee information to Chen Wenhui in the QQ group was in Sichuan. Later, the police investigating the case arrested the criminal suspect Du Tianyu in Chengdu. The police found that the person they caught selling information had a more special identity in this case. Suspect Du Tianyu: That day, I logged on QQ to see if anyone had left me a message. Seeing that Chen Wenhui had been leaving messages for several days, I asked if I was there. Then I said I was there. He said he wanted to buy information about candidates in Linyi, Shandong. Du Tianyu, 18 years old, from Yibin, Sichuan. The police verified that Du Tianyu sold Shandong examinee information to Chen Wenhui more than 10 times through QQ, making illegal profits of more than 14,000 yuan. Reporter: Why did you choose to use QQ groups to sell this information? Suspect Du Tianyu: An underground industrial chain like this usually operates on the QQ group. It should not be easy to find it in other places, and there is no market. One is that its requirements for real-name systems are less strict than those for these shopping websites, which are more anonymous and more convenient to communicate. Eighteen-year-old Du Tianyu, whose screen name "Mage" uses hacking technology to steal information, has often gone to Internet cafes to play games since the fifth grade of primary school. He dropped out of school when he was in the second grade of junior high school. While playing online games, he became interested in hacking technology and began to try using hacking technology to obtain other people's data and information online. Du Tianyu gave himself the screen name "Mage", which means he had mastered magic. Reporter: How did you obtain Xu Yuyu's personal information? Suspect Du Tianyu: It is a college entrance examination registration system, an online registration system. I took a look at it at that time, and then based on experience, I felt that there might be a problem and a loophole. Then I tested it and found that there was a loophole, so I uploaded a Trojan horse and obtained access to the website. permissions. Selling 600,000 pieces of examinee information and obtaining more than 50,000 yuan in stolen money. In April this year, Du Tianyu used a security loophole to invade the "Shandong Province 2016 College Entrance Examination Online Registration Information System" website and downloaded more than 600,000 pieces of information on Shandong Province college entrance examination candidates. After the college entrance examination, they began to illegally sell them online, earning a total of more than 50,000 yuan in stolen money. This is how Xu Yuyu's personal information flowed from hackers to scammers. Hackers invading databases is just one way for information to be leaked. Individual employees of companies and institutions that have a large amount of citizens 'personal information actively resell customer information, resulting in the bulk disclosure of customers' private information. Wang from the Jiangsu branch of SF Express Company has been engaged in express delivery for more than 5 years. Since May this year, he has taken advantage of his position to copy a large number of customers 'personal information from the company's internal system for sale. This personal information involves the customer's name, phone number and detailed address of his home or unit. In May this year, Wang was arrested by police in Heze, Shandong. Suspect Wang: The bank's "ghost" sells customer credit information: The middleman added me as a friend through WeChat. He knew that I was working at SF Express and asked me if I could find the address with my mobile phone number, which is the delivery address. I said that I could check if I had sent a courier, and then he gave me my mobile phone number to check it. One was 30 yuan, and he sent it to me using a WeChat red envelope. Reporter: How many can you check at most? Wang: It's more than 1000 yuan a day at most. There are two or three missing items. Bank employees sell customer credit information. Zhen, an employee of Ping An Bank of Henan China, also driven by interests, took advantage of his position to copy a large amount of customer credit information from within the bank for sale. The customer's personal information involved includes: name, work history, insurance history, and detailed information such as credit loan. Reporter: How much is one? Suspect Zhen: Around 20 to 30 or 40. Zhang, a staff member of Shanghai Telecom's Know-it-all, took advantage of his position to illegally sell professional positioning software to information traffickers. This positioning software is directly connected to the telecommunications database. Through this positioning software, information traffickers can obtain the real-time location of any telecommunications mobile phone user across the country. Zhang has now been arrested by Shandong police. Why can harassing calls call us by name? Why can fraudulent phone calls tell us our ID numbers? Because our personal information has become a commodity for sale, the personal information that has become a commodity no longer belongs to us personally. The disclosure of citizens 'personal information has become an accelerant to the high incidence of telecommunications fraud crimes. Since the Ministry of Public Security deployed a special campaign to crack down on the Internet in April this year, as of September 21, more than 1200 criminal cases have been solved. More than 3300 criminal suspects have been arrested, including more than 270 insiders in banking, education, telecommunications, express delivery, securities, e-commerce websites and other industries, more than 90 online hackers, and more than 29 billion pieces of information have been seized. Zhang Hongye, deputy director of the Cybersecurity Bureau of the Ministry of Public Security: The public security organs will continue to increase their efforts to crack down on criminal activities that infringe on citizens 'personal information, focusing on cracking down on trafficking, theft, and illegal utilization. At the same time, they will urge all links that are likely to cause the disclosure of citizens' personal information., increase self-examination and self-correction efforts, especially e-commerce platforms, online payment platforms, and Social networks platforms, must increase self-inspection efforts to prevent citizens 'personal information from being leaked.On August 19, 2016 (July 17, 2016 in the lunar calendar), Xu Yuyu's case was scams: hackers sold candidates 'information and scammers committed crimes according to the script.
