Recently, a reporter from "Rules of Law Daily" learned from the Public Security Bureau of Nantong City, Jiangsu Province that in the "Net Network 2020" special operation, under the unified command of the Ministry of Public Security and the Public Security Department of Jiangsu Province, Nantong police successfully cracked the country's first case of using the "95" section. Assisting in communication network fraud cases, arresting 15 criminal suspects, destroying 3 communication technology companies engaged in criminal activities, seizing 21 "95" numbers, more than 20,000 illegal Internet telephone lines, and discovering 155 downstream business relationship companies, The amount involved is more than 22 million yuan.
I want to borrow a "routine"
At the end of 2019, Nantong citizen Sun received a phone call starting with the "95" number, asking if he needed a loan. After learning that Sun had loan intentions, the two parties added WeChat to each other.
During the chat, the other party asked Sun the amount of loan he wanted, and Sun reported 300,000 yuan after considering it. Under the guidance of the other party, Sun downloaded a software called "360 Finance App" and registered.
"At that time, the other party told me that you can save 6 months of interest by recharging 1799 yuan." Hearing such "benefits", Sun immediately transferred the money to the other party's account to save interest. Unexpectedly, just as Sun was waiting to receive the payment, the software prompts that the bank account is incorrect.
In order to "change" the account, Sun paid another 20% of the loan principal, which is a handling fee of 60,000 yuan. Account error, cash withdrawal need to pay insurance, need to recharge VIP to get points... just like that, Sun not only did not get a penny, but also remitted 297,123 yuan. At this time, Sun realized that he might be deceived and called the police for help.
Coincidentally, Fan from Anhui also received a phone call that also started with the "95" number. After downloading the software, he transferred 11 transactions and was defrauded of more than 230,000 yuan. It was not until he received a call from the Nantong Anti-fraud Center that Mr. Fan realized that he had been deceived.
"There are many victims like this. The phone numbers they receive start with '95'." Xu Pingnan, deputy captain of the third team of the network security detachment of the Nantong Public Security Bureau, introduced, because the "95" number segment is generally used for corporate calls. The center and customer service hotline have reduced the victim's alertness to a certain extent.
The Network Security Detachment of the Nantong Public Security Bureau discovered during the preliminary investigation that since March this year, the "952750××" number segment has been used extensively to make fraudulent calls, which has been linked to 266 fraud cases across the country. To this end, the Nantong Public Security Bureau quickly established a task force with the “top leader” as the team leader and the participation of the main persons in charge of cybersecurity, criminal investigation, legal system, and Chongchuan Public Security Bureau to investigate the series of cases.
Lock the "source" of the number segment involved
During the investigation, the task force discovered that the number "95" involved in the case was applied by a communication technology company in Nantong, and the legal representative was a 39-year-old Tongzhou man Qin Moutong. In April this year, the task force arrested Qin Moutong and other 4 criminal suspects based on the clues of the preliminary investigation. After that, two communication companies located in Shenzhen entered the attention of the task force.
According to Qin Moutong, he had applied for the fixed telephone number segment "0513-85××××××" in the name of the company, and then sublet this number segment to others, earning more than 2 million yuan a year. These numbers were used for fraud, advertising and sales activities, and were later reported and complained by the masses. These numbers were banned and the company was also "blacklisted" by local operators.
After being on the "blacklist", Qin Moutong started the idea of applying for the "95" number to make money. Subsequently, Qin Moutong applied for the “952750××” code number certificate through the agency agency. But how to get the number to connect to the network for normal use, complete the voice landing, and let the operator enable the number to make calls, has become the most important thing for him to solve.
For this reason, Qin Mouzhong contacted Zhang Mouzhong, who started a communications company in Shenzhen, and the two parties hit it off. It was agreed that Qin Moutong would provide the voice landing service materials for the number "952750××", and Zhang Mouzhong would be responsible for the number. Carry out landing and line transformation, and the transformed line will be used by both parties according to a certain proportion.
On April 29, the task force followed the line and arrested 5 criminal suspects including Zhang Mouzhong. After interrogation, the task force learned that Zhang Mouzhong was only a "second road trafficker", and that the person who actually completed the voice landing was Yang who opened a technology company in Shenzhen. On April 30, the task force arrested 6 suspects including Yang and brought them to justice based on clues provided by Zhang.
Bring out more than 100 downstream companies
According to Yang's account, he completed the voice landing through an operator in other provinces, and tried to modify the line of the number section through network equipment, and allocated the 100 numbers of the "952750××" number section into 5000 network telephone lines. Among them, Yang received 4000 pieces, Zhang Mouzhong received 600 pieces, and Qin Moutong received 400 pieces. Subsequently, the three individuals used their own resources to find customers and subleased the line for profit at a higher price than the operator.
"During the case, we found that most of the customers who leased lines used their numbers to commit fraud and other illegal criminal activities." Zhang Jian, head of the network security detachment of the Nantong Public Security Bureau, introduced that during the leasing process, the upstream company’s access screening mechanism It is in vain, criminal gangs only need to provide false company information, they can rent network lines and use dynamic numbers to make network calls anytime, anywhere. Internet telephony is not restricted by region, and has a strong concealment, which makes fraud gangs more hidden.
“Of the 266 cases implicated, the most are credit card and loan fraud.” said Cao Yang, a police officer from the Internet Security Brigade of the Chongchuan Branch of Nantong Public Security Bureau. The fraudsters used Internet phones to import contacts in batches and used the group call function for “widening”. net". Some criminals even use the intelligent voice function to dial the test first, and then turn to manual services to implement the next step of fraud after the victim "hooks".
In the process of handling the case, the task force discovered that the "95" number held by Yang did not only come from Qin. According to investigations, since 2018, a group headed by Yang has deployed voice services for more than 10 "95" numbers through an operator from other provinces, and then leased the lines to downstream business companies through technological transformation. Profit over 8 million yuan.
After three months of careful investigation, the task force compared more than 800 online fraud cases across the country and found 155 downstream business relationship companies.
"This case is the epitome of many black and gray industries that provide assistance to criminal groups such as network fraud." Chen Bing, deputy director of the Nantong Public Security Bureau, said that the "Telecommunication Network Code Resource Management Measures" issued by the Ministry of Industry and Information Technology clearly stipulates that "95" Segment number users are not allowed to transfer or lease lines, or operate fixed telephone services, Internet telephone services and other telecommunication services in a disguised form.
At present, all criminal suspects involved in the case have been transferred to the procuratorial organ for review and prosecution due to the crime of helping information network criminal activities.
