According to the analysis of Tencent security experts, the decline in the amount of money involved in telecom network fraud is mainly due to the joint heavy blow of many ministries and commissions of the country and the mass collaboration of public security, operators, banks and Internet companies, which have realized the fraud from the source, active Defense of phishing websites and fake base station SMS.
In order to effectively prevent and accurately crack down on telecom network fraud, the central comprehensive management office, supreme law, supreme inspection, Ministry of Public Security, Ministry of Industry and Information Technology, People’s Bank of China, china Banking Regulatory Commission and others jointly issued “Several Opinions on Further Preventing and cracking down on new crimes in telecommunication networks”, and the Ministry of Public Security and relevant departments issued “notice on preventing and cracking down on crimes of telecommunication network fraud”. At the same time, anti-fraud centers have been established across the country, emergency stop payment and rapid freezing mechanisms have been established, and a number of laws and policies have been promulgated.
In addition, Internet companies are involved in anti-fraud, providing technical and data support for anti-fraud, making the anti-fraud mode change from active reporting by users to active interception and defense by public security and operators. For example, using Tencent Eagle Eye anti-fraud system to deploy to the operator Gateway, you can restrict the outbound of fraudulent calls from the source; Public security across the country deployed Tencent KIRIN pseudo base station real-time discovery system, it can help the public security to lock the number, location and crime status of pseudo base stations in the jurisdiction and capture them accurately.
According to the data, in 2016, the number of telecom network fraud cases cracked by public security organs across the country increased year on year, with a total of 83000 cases solved and an increase of%; The momentum of a sharp rise in telecom network fraud cases was curbed, since last September, the number of cases has dropped sharply for four consecutive months; The loss of telecom network fraud cases has dropped by 10.9% year on year.
Internet fraud accounts for 75%, with the highest amount of online fraud.
The report shows that Internet fraud ranks first in 75%. From the perspective of the proportion of the amount involved in fraud, online shopping fraud accounted for 59 percent, followed by online business investment fraud accounted for 21 percent.
(Data source: big data report on anti-telecom network fraud in the first quarter of 2017)
It is understood that the reason why online shopping fraud accounts for the highest proportion is mainly because the current online shopping market is super hot, and the information leakage of online shopping users is repeatedly prohibited. At present, the number of online shopping users in our country has exceeded 0.4 billion, and criminal acts such as user information leakage on online shopping platforms and courier selling user information for profit have been exposed many times. In online shopping fraud, criminals usually induce users to transfer money to defraudation on the grounds of paying commission, abnormal delivery, refund for shopping, etc.
Secondly, the higher amount of fraud involved is online commercial investment fraud, which is divided into credit loan fraud and online stock investment fraud. Criminals usually induce them to pay security deposit through the Internet on the grounds of Agency high credit card (500000-1 million) or low interest loan, which is defraudation. Or lobby and induce users to open false securities accounts and transfer money to the accounts to purchase stocks and crude oil through high-yield and low-risk methods. Thus, defraudation per capita are thousands to tens of thousands.
For example, there is an online investment fraud case involving 600000 yuan in the Shenzhen special line report that the victim knew a man through the Internet, later, the other party introduced to a company “Zhongcheng Group” investment “spot” more than 100 million yuan, of which the loss was more than 600,000, suspected of being cheated.
Tencent security experts remind that the key to telecom network fraud lies in the anti theft of funds. As long as the funds are controlled, losses will not be caused. The general public should not transfer or remit money to any strange account, and do not easily open the URL links in social software and text messages, let alone enter bank accounts, online shopping payment accounts and passwords in these web pages. When you encounter phone calls or text messages such as online shopping refunds, you must carefully verify the url link to avoid logging on to the phishing URL and causing the funds to be stolen.
