Thinking that I met love just around the corner on the Internet, I fell into the “slaughterhouse” of love. Slaughter plate scams aren’t new, but victims keep turning up repeatedly. Recently, CCTV reported that the police in Changzhou, Jiangsu received an alarm in April this year. Ms. Wu said that her boyfriend she met on a dating website claimed that he made money using digital currency, but was defrauded out of 15 million yuan. After nearly half a year of investigation, the Changzhou police arrested the fraudulent group not long ago, more than 370 cases involved worth a total of about 120 million.

Another example is that the Qinbei branch of the Qinzhou City Public Security Bureau recently destroyed a telecommunications fraud ring that committed fraud in the form of “killing pigs”. The amount involved was more than 3 million yuan.
Xiaoyu, a security operations expert at Tencent 110, told China Business News that last year, there was no difference in the ratio of male and female slaughterhouse victims, but this year it has gradually shifted towards women. Almost 70% of slaughterhouse fraud complainants were reported by women, mainly through marriage and love platforms. Dating software finds the target, precisely locates the victim, the chain of techniques is intertwined, and the structure is complete. Among the various types of online scams this year, the victims of the killer pig plate scam suffered the most.
Massacre disk fraud is just the tip of the iceberg of online fraud. Nowadays, the mode of operation of Internet fraud is showing a trend of professionalization, corporatization and chaining. Criminal methods have gotten smarter and a whole chain of fine division of labor has gradually been formed at each link, such as “malicious registration-drain fraud-money laundering”. .
Most Transaction Fraud Reports, Most Money Fraud
If whistleblowers who have committed online fraud since the beginning of this year are given a “user profile”, one characteristic is that the general age is younger, mainly concentrated in those between 20 and 29 years old. The main types of fraud that are defrauded are transaction, discount and appointment fraud; and 40 years The types of netizens mentioned above that are vulnerable to fraud are financial credit, counterfeiting, and low-price scams.
Judging by the typical types of high incidence scams in 2020, the Spring Festival period in previous years is usually the time when the rate of online fraud is low, but this year due to the epidemic, online scams related have shown an upward trend. From a data point of view, price bidding accounted for 78.1% and epidemic fraud for 27.4% (mainly referring to mask trade, fundraising fraud, epidemic material fraud, vaccine fraud etc.) During the epidemic, masks became a necessity, and some people hoarded masks and did not get paid. Others falsely claimed that they were issuing epidemic prevention subsidies and sent false red envelope links to commit fraud.
According to data from Tencent, at 4:00 p.m. on March 24, the Tencent Guardian Program security team assisted national public security organs in arresting more than 4,000 suspects and solving more than 10,000 cases.
During the summer holidays of July and August this year, part-time fraud began to enter a period of high incidence. Due to its low threshold, wide audience and simple operation, university students, mothers and unemployed people with a relatively weak awareness of prevention have become the main targets of hoaxes. Part-time job scams are particularly prominent in entry deposits and fake orders. Defrauding trust with small profits has become the key to fraud success. Therefore, there are cap fees and prepayments are often scams.
The type of fraud that has increased the most this year is refund fraud. The start of the school season in September and the online shopping carnival in November are the time when reports are high. At the same time, the drain on third-party platforms, including short videos, is another incentive for markdown growth. These types of scams are based mainly on money returns and purchase returns, with various modalities, most of the victims were born in the 2000s and 90s, who like to follow stars and are the main group of online purchases.
Summarizing the new features of online fraud in 2020, Haiwen, an expert on the Tencent Guardian Program security team, told a China Business News reporter that one is to hire normal user accounts to participate in the fraud. For example, through “part-time crowdsourcing”, users are induced to block the production of normal WeChat groups, users are induced to spread drain information, and users are induced to provide payment codes. For normal users, it may be a part-time job, but it has become an “accomplice” of the black industry.
The second characteristic is that a variety of black products are linked to each other. Let’s take Shayupan as an example. Its essence is a crowdsourcing fraud model. In addition to the “fisherman” responsible for the fraud, it also involves fake link forgery and app developers, fake QR code producers providing money laundering and companies. Second scammers, account resellers, promoters, and related personnel on multiple platforms are in cahoots with each other, making prevention difficult for users.
The third feature is that scam gangs update new black and white crime tools, including ever-changing virtual IP positioning to increase the difficulty of detection; The use of digital currency to launder money has also become a new favorite of the money laundering industry; deflect fraud part-time, also using artificial intelligence phones. call. For example, technically speaking, fraudulent gangs can collectively use virtual IPs to locate malicious accounts in Kunming, and even match the two-dimensional code consumption records of merchants in Kunming, and mistakenly derive a map of gangs that committed crimes in Kunming to carry out a fraud.
Where is the difficulty?
Wherever the traffic is, the black nativity will go. When short video platforms occupy more and more hours of use, black production online has long been looking at these platforms. For example, on this year’s short video platform, incidents of fake Jin Dong and other celebrities posing as celebrities have attracted a lot of attention from society.
This is actually a new feature of internet fraud in recent years: long-chain, cross-platform crimes. Fraud gangs divide work and collaborate, some of which are detours on short video platforms or love and marriage platforms, and some of them will implement fraud on social platforms or online banking, and third party payment platforms as well as well as switching between online and offline scenes. Not long ago, Zhou Ran, director of the Douyin Security Center, told CBN that such problems have made it difficult to obtain evidence of online fraud and follow it up.
Haiwen also mentioned that there is currently no established model for cooperation, and a major challenge is whether each company can establish mutual trust in black data.
In addition to calling for the establishment of a coordinated combat mechanism, the difficulties of cyber fraud also include issues such as intelligence and chaining.
Haiwen told CBN reporters that since the black industry in fraud crimes, criminals have used hot technologies such as machine learning, artificial intelligence and big data in all aspects of fraud. For example, black industry uses machine learning and artificial intelligence. Smart technology breaks the verification code authentication system of Internet companies, etc. Especially since this year’s development, the crooks’ technology has been further optimized. In the first half of the year, Tencent supported the Ruokuai code platform that the Sichuan Public Security vigorously seized. Criminals have used artificial intelligence + part of the manual method to break the sliding verification code; The platform jumps to the IP address at will, changes the characteristics of the terminal hardware to avoid police tracking, etc.
From the perspective of the industry fraud crime division, in past online fraud cases, criminals often commit crimes in groups, get to know each other and work together. However, in recent years, the upstream and downstream criminals’ division of labor has become more refined and professional, and has gradually been formed.From malicious registration, the entire black industry chain goes through the account maintenance, drain, fraud, and money laundering links. In this black industry chain, criminals do not even know each other, and the use of the Internet to provide services in the division of labor and cooperation has made the threshold for crime ever lower.
In order to block illegal transactions more effectively, Tenpay has established a Cassia risk control system platform for comprehensive prevention and control and cracking down on abnormal capital flows in WeChat payments. Based on analysis of black property dynamics and fraudulent user behaviors, it helps law enforcement and relevant government regulatory agencies crack down on cybercrime groups. Furthermore, WeChat Pay has also launched a special anti-fraud project to combat fraud on the three links before, during and after the event. Taking the transactions in the event as an example, to avoid user losses, WeChat can intervene in high-risk transfers based on the evaluation of its system and allow users to actively enter a certain cooling-off period.
In a recent interview with China Business News, many platforms asked: At the industry level, as diversion scenarios become more and more diversified, the responsibilities of the platform should not be limited to one platform. Operators, Internet companies, financial institutions, etc. If we can conduct coordinated cross-platform operations and joint strikes with more organizations, we will better solve the problem of online fraud.
