Conspiracy analysis behind the phone call

Conspiracy analysis behind the phone call

Every one of us has suffered from harassing calls, sales promotions, and financial management. The "one voice" harassing call account for a large proportion. According to incomplete statistics, all the phone numbers reported by the cheetah Mobile Security Center on September 2015, "One sound" Harassment calls accounted for 45% of the total Report Volume.

So what is the purpose behind such harassing calls, how are their sources of profit, and how should we avoid "sound" harassment?

1. What is a "ring" call?

From a technical point of view, someone uses a special group dialing device or software to automatically dial a specified number or number segment, and immediately hangs up when the phone number is fixed or displayed on the phone. If the victim calls back the phone number, he or she may be charged or receive all kinds of sound advertisements.

Ii. Classification of "One Voice" calls

Currently, most of the calls are normal mobile phone numbers, such as the 130-139,150-159 mobile phone number segment. After you call back such numbers, you may be charged for local calls or long-distance fees if you connect them, however, there will be no so-called information fees. There are three main purposes for such calls:

1. Some enterprises induce users to call back for advertisement promotion;

2. Some criminals induce users to call back to publicize the lottery and prostitution information;

3. Some criminals induce users to call back for telecom fraud.

In addition, there is also a type of non-common numbers displayed, such as the phone numbers starting with 96,168. These numbers are mainly owned by sound stations or Information Service (sp) companies that have obtained formal operation qualifications, the information service fee may be incurred when you call back such numbers.

3. parsing the illegal advertising industry chain behind the "sound"

First, the Group call organization pulls illegal information such as Liuhe lottery and prostitution advertisers (most advertisers are gray enterprises engaged in fraud, illegal goods sales and activities );

Second, make the relevant advertising ring tones and bind them to a third-party number (generally provided by advertisers );

Once again, the local agents of the group Dialers are recruited, and local agents use the purchased ordinary mobile phone number for call transfer settings to third-party numbers, then, the local agents call the group to trick victims into recalling and listening to advertisements. The basic process is as follows:

Illegal advertisements generally use a proxy mechanism to increase the callback rate. Generally, users will view the region to which the caller belongs. If the caller finds that the region is unfamiliar, the user will give up the callback. To improve the callback rate, generally, the agency mechanism is used to implement local promotion (the incoming call looks like a local number, and illegal advertisements, such as online gambling, are heard ).

After receiving the advertiser order, the group-sending organization will distribute the advertising materials to the first-level agents, and the first-level agents will develop terminal agents on the Internet to ensure the monthly income commitment and other means, and sell group dialing devices to terminal agents in various regions. The terminal agent only needs to handle the mobile phone card and then perform group dialing.

4. How to make a profit by making a ring call

The Group call organization charges the gray advertisement advertiser Based on the return effect and pays the Commission for each agent's performance. The basic procedure is as follows:

According to practitioners, the average daily income of terminal agents is 10 to 10 according to the types, cycles, and effects of advertisers ~ 100 yuan, the first-level agent and "Head Office" determine the income based on the development of the deprecation and the number of advertising orders received in the month, generally ranging from tens of thousands to hundreds of thousands.

V. Derivative scam: Join the mobile phone fees

In addition, a derivative scam has spread widely on the Internet. Some people publish messages in the name of "Mobile Phone Fee-absorbing" to attract victims to buy high-priced "fee-absorbing devices", or directly defraud the franchise fee.

6. rumor about the "deduction of the callback voice station"

Rumor 1

It is incorrect to say that the domestic voice station is immediately deducted.

Currently, the State has clearly stipulated the above-mentioned charging standards for domestic voice stations. The general information fee will not exceed 2 RMB/minute and will be paid for online, in addition, when you call the voice station, you must first notify the relevant charging standards of the free voice, and start to calculate the information fee after 6 seconds after the user presses the button to confirm or the voice notification is played, therefore, if the victim only calls a real domestic voice station number, there will not be a phenomenon that "the high information fee will be deducted immediately after a callback;

In addition, various audio stations are difficult to monitor in content management, so mobile has now canceled the audio service, and China Telecom and China Unicom have made stricter restrictions on the audio service.

Rumor 2

It is not reliable to deduct high fees immediately after the callback is transferred to an overseas voice station.

Previous news on the Internet and various new news media have reported that "Mr. xxx/MS immediately deducts high fees by dialing a common number." After detailed analysis and confirmed by the carrier, the reason is as follows:

1. The domestic phone number (mobile phone or fixed-line phone number) of ordinary users cannot directly call overseas calls without activating the international roaming service;

2. Domestic phone numbers cannot be transferred directly to overseas voice stations;

3. China's operators have not signed settlement agreements for special billing of voice stations with overseas telecom operators. They only have universal international long-distance settlement agreements, even if domestic users call foreign voice stations, at most, you will only be charged for international long distance flights, rather than the so-called "Information fee ".

Summary

1. Most of the reports that "a large fee is deducted when a call is made back" are false. If you think there is a discrepancy in the phone bill, you can complain to the carrier;

2. The main purpose of an alarm is to trick advertisements into broadcasting and get advertising fees;

3. Criminals can also use the "beep" command to induce users to call back and commit Telecom fraud (for example, charging the "Public Security Law" for fraud, guess who I am, your son needs remittances, etc );

4. The so-called low-risk and high-income Internet fees to join is a lie. What criminals want to earn is not the money of ordinary mobile phone users, but the money of the franchisees.
