Behind the "free traffic" is actually a black industrial chain. The reporter recently learned that "free traffic" products, including mobile phones, software, tutorials, etc., have been distributed throughout the network. However, according to insiders of the operators, these so-called free-traffic products are the product of drilling operators' exploits, exploiting the loopholes of operators targeting free traffic, which can cause operators to lose hundreds of millions of dollars each year. In the eyes of the industry, once this phenomenon is formed, it will increase the network pressure and economic losses of operators, and also improve the maintenance and service costs of operators for network construction. Although operators have begun to take measures to fill the loopholes, there are still new methods of confrontation among technicians.
On an e-commerce platform, the reporter entered “free traffic†and found nearly 3,000 product information, which are representative of the following three products:
The first product is called “free unlimited mobile phoneâ€, and the price is about several hundred yuan. The merchant describes it like this: “This mobile phone cares about the card plus the core technology and the model color of the mobile phone. This mobile phone is a machine card. You don't need to recharge any extra fees, you can use it directly to open the hotspot, and it is easy to operate. Up to 8 devices can be connected.†The merchant said that the mobile phone traffic is based on the server terminal, enabling remote acceptance of the network, without any traffic and charges in the card. .
The second product is "unlimited traffic software", the price is only 1 yuan. According to the introduction, the seller will give the buyer account and password. The software may need to consume about 50KB of mobile phone package traffic every time you log in or connect. The mobile phone's own software allows a small amount of traffic in the background. One seller said: "Our company cooperates with mobile, contracted monthly traffic and traffic pool, through our company's technology development traffic distribution system, to achieve unlimited use of traffic."
In addition, there are also merchants selling "free brush flow tutorial", the price is 9.9 yuan. On the store's page, there is not much introduction about the product. It only says: “The shop has cooperated with the studio. The success rate of the new tutorials obtained from the studio is over 99%. The tutorial will be updated from time to time. No further fees will be charged, and one purchase will be used forever.†Because the customer service has no answer, the reporter has no way of knowing how this free brush flow tutorial is used. The store's comment area shows that no matter whether it is a mobile phone, software or tutorial, there are not a few consumers who buy it. However, some of the comments are “easy to useâ€, and some consumers say that the merchant is a “swindler†and the product cannot be used.
Drill operator vulnerabilityWhen you first saw these products, you would be mistaken for these kinds of products to be produced by merchants and communication operators. The reporter conducted a verification request to the relevant person in charge of China Mobile. The person in charge pointed out that China Mobile has never had such a business. The relevant person in charge of China Telecom (microblogging) told reporters that the so-called "free unlimited traffic" is a "stolen" from illegal operators. That is, the relevant technical personnel drilled the vulnerability of the operator "free directed traffic".
It is understood that in order to improve the service for operators, operators have always had free directional traffic. A large number of Internet companies cooperate with operators, and both parties share the cost of traffic and give users targeted traffic-free services for designated services. Operators can not only improve the user's mobile Internet experience and mobile network stickiness, but also increase traffic access, form user traffic habits, and then bring revenues on services such as paid content.
In order to avoid loopholes and risks, operators will clearly distinguish whether users are using traffic-free services or accessing Internet services normally. Generally, the operator adds the IP address of the server of the streaming-free service to the whitelist. When accessing the whitelisted URL, the user can access the Internet with free traffic, access is not billed, and even to simplify the maintenance complexity, the label authentication is directly performed.
However, such a way has been turned into a tool for profit by illegal traders. According to the technical staff, traffic sellers only need to apply for a VPS cloud host on the Internet, set up a virtual private network server (VPN), and then through uncomplicated camouflage, the operator can think that the traffic of this VPN request is A traffic-free website from the carrier. In this way, the VPN traffic they control becomes the one that is paid by the operator. Thereafter, by controlling the VPN account permissions, the traffic reseller can sell the carrier's "free traffic" to the user at a low price.
Losing hundreds of millions per yearLast year, the domestic vulnerability reporting platform, Wuyun, announced that in order to provide convenience to customers, operators set up a whitelist of free traffic charges. When the billing system detects that the user is accessing the URL in the whitelist or receiving the MMS, it will not Deductions are made, and if the loopholes are expanded, the operator will lose too much.
Some insiders of the operator told the reporter that this situation is actually a loophole in the billing instructions or billing information. Some people modify the billing instructions in the process of transmitting information, and the wrong commands are sent to the billing system, which will lead to the above. As a result, this is not a problem with the billing system. If the billing system has a loophole, it will have serious consequences; the operator has optimized the billing information unit.
In this regard, independent telecom analyst Fu Liang (microblogging) believes that this vulnerability is the use of some free channels for special applications, but the space for this simulation is limited, resulting in losses that are not large for operators. The relevant person in charge of China Telecom said that the specific figures of unscrupulous traffickers’ “stolen†traffic losses have not yet been counted. However, some experts believe that the “free traffic†gray industrial chain has formed a scale, and it will continue to develop at such a speed. As a result of no small loss of property, according to estimates, the total loss of the three major operators on this issue each year will be hundreds of millions.
It is reported that Beijing Unicom has revised the billing model to shield the current part of the directed traffic free flow scheme, and other operators have also launched a comprehensive filtering and troubleshooting of this service. However, since operators have a large number of servers deployed throughout the country, and each province has its own billing system, it is extremely difficult to verify the faults.
