85% of fraud through the Internet Experts say that full-link anti-fraud can cure the root cause

Recently, the latest issue of "People's Living Room" broadcast a special program - "Raising Awareness of Anti-Fraud and Guarding the People's "Money Bags"" "". In the program, Chang Wen, deputy director of the Anti-Fraud Special Class of the Ministry of Industry and Information Technology, deputy director of the Center for Preventing and Controlling Telecommunications Network Fraud of the Institute of Security of the Chinese Academy of Information and Communications Technology, Yang Fan, a police officer of the Haidian Branch of the Beijing Municipal Public Security Bureau, and Wang Le, a system security expert of Xiaomi Group, were invited to attend to discuss the new characteristics and trends of the current telecommunications network fraud, and how to prevent telecommunications network fraud and other hot topics.

Scams are characterized by specialization and precision, and if you are not careful, you will fall into it

Chang Wen, director of the Institute of Security of the Chinese Academy of Information and Communications Technology, pointed out in the program that with the rapid development of network technology, telecommunications fraud has gradually shifted to the Internet field, and has shown the characteristics of integration, precision, specialization and cross-border.

According to statistics, more than 85% of the current fraud is carried out through the Internet, and the fraudsters first carry out false propaganda through the mainstream short video platform, induce the victim to transfer to other platforms for private chat and carry out fraud. At the same time, fraud is also more targeted and directed, fraudsters combined with the current social hotspots and the personal information of fraud targets to carefully design fraud scripts, comparable to a logical "script killing" game.

For example, during the epidemic period, fraudsters will impersonate epidemic prevention personnel to carry out fraud, first of all, fraudsters obtain through illegal means, can accurately report the victim's information, greatly increasing the deception of fraud. Then a professional and systematic criminal gang began to carry out "precision" fraud on the victims through counterfeit websites, apps, short videos and role plays, and each link had a clear division of labor and interlocked links, forming a strict fraud closed loop.

Officer Yang Fan stressed in the program that now fraudsters have successively moved to Southeast Asia and other countries to carry out crimes, which has brought great challenges to tracing and tracing and investigating and cracking down. According to statistics from the SPC, the proportion of overseas dens in the crime of wire fraud has exceeded 60%.

In the process of cracking down on such crimes, the public security organs have gradually realized that due to the increasingly professional and precise nature of telecommunications gangs, it is difficult for ordinary people to get out of the trap once they fall into a trap. How to identify and deal with it early has become a new focus of anti-fraud work.

Technology empowerment to support the anti-fraud "protective net"

Fraud methods emerge in an endless stream, ordinary people to see through a pattern of renovation, the layout of the trap, the need for the power of science and technology to participate in it, to build a front-facing "anti-fraud firewall".

Police officer Yang Fan said that in recent years, the relevant departments of the state have invested a lot of resources and energy in anti-telecommunications fraud work, and the App of the National Anti-Fraud Center has intercepted, marked and reminded a large number of fraudulent acts for users after two years of promotion, protecting the safety of people's property. At the same time, he is also very pleased to see the investment of domestic smartphone manufacturers in the field of anti-fraud. The mainland is the world's largest smartphone market, and smartphones are the nodes where telecom networks and the Internet link everyone, and the efforts of mobile phone manufacturers in anti-telecom fraud are crucial.

The anti-fraud app needs to be downloaded by the user himself, so if the anti-fraud app is not downloaded, can the user only "run naked information", and can the mobile phone operating system itself have anti-fraud functions?

Xiaomi Group system security expert Wang Le said that in today's highly developed mobile Internet, more and more personal information is retained and circulated in the network environment, and once personal information and privacy data fall into the hands of criminals, it undoubtedly improves the accuracy of fraud and greatly increases the risk of fraud for ordinary people, so doing a good job in personal information security and privacy protection is the first step in anti-fraud work.

The latest Xiaomi mobile phone operating system (MIUI 13) on the basis of privacy protection to strengthen the full-link anti-fraud capabilities, MIUI 13 through the self-developed MACE edge computing platform and differential privacy technology, changed a number of scenes that originally need to upload user data, many functions in the mobile terminal can complete offline operations, greatly reducing the probability of user privacy on the network retention and circulation. Differential privacy protection technology is also used to ensure that even if the data needs to be uploaded, it is not the user's real data, but only the data used for overall trend research.

At present, the MIUI 13 operating system can do early warning and interception in the key links of the entire link of fraud, such as the detection of fraudulent SMS, the interception of malicious URLs, the reminder before user transfers, etc. A full set of "combination punches" can minimize the risk of users being defrauded. It is worth mentioning that these functions are judged by the algorithm of the mobile phone system itself, do not need to be networked, and fully protect the privacy of users.

Taking the "fraud warning" function as an example, when the user receives a scam call or text message, MIUI 13 will directly warn the relevant page, so that the scam call and SMS can be seen at a glance, and the "official logo" function provides identification for the phone and sms of the relevant state departments to further avoid users from missing important information. When transferring, the "Transfer Protection" function will be activated to warn of risk transfers, so as to avoid users being deceived.

At present, MIUI security and privacy protection has become a good practice case in the industry, which has been learned and followed up by Apple, Google and other manufacturers, and has promoted the progress of the entire industry.

At the end of the program, industry anti-fraud experts called on the anti-fraud work to require the judiciary, the industry and enterprises to work together to govern, use the power of law and science and technology, effectively protect the "money bags" of the masses, protect the privacy and security of the public, and establish a solid "anti-fraud protection network" for the public.
