Many users may have such an experience, just browsing some websites with their mobile phones, and did not leave a phone, but received a sales call from a related industry.
Harassing Phone Number 1: Hello? Hello, my side is the Fire Certificate Application Center.
Harassment call 2: The down payment is from 250,000 yuan, I would like to invite you to learn more about it.
Reporter: How do you know my phone number?
Harassing Phone 2: Now it's all big data, big data scraping.
The relevant state departments have been rectifying, why are there still people making harassing calls? How did they get our browsing behavior precisely?
Rongying Communication, specially for some telemarketing companies to build outbound call system, provide outbound call lines. Manager Feng of the company said that there are many telemarketing companies that make harassing calls through their systems, but the words are disguised.
Rongying Communication Sales Department Manager Feng: The opening words of that word change a bit, that is, in the form of a return visit, for example, directly say, Hello, my side is a certain company. Recently, I have contacted you about the communication of a certain product before. What are you going to do and think about now? Do you know more about it here?
Reporter: Is it that there is no actual communication?
Rongying Communications Sales Department Manager Feng: Yes.
Reporter: Is this kind of flexibility good?
Rongying Communication Sales Department Manager Feng: Yes.
When it comes to harassing phone calls, most of what Manager Feng of the company said is jargon in the circle that outsiders do not understand.
Rongying Communications Sales Department Manager Feng: The Civil Code of the People's Republic of China clearly stipulates that it is not possible to be unfamiliar with customers. You say Mobai, as we usually do, or Mo call (dial).
Reporter: Mobai Mo call (dial) means that the other party does not agree, or is it equivalent to making a harassing phone call? ”
Rongying Communications Sales Department Manager Feng: Yes, in fact, it is blind beating.
"Mobai" is just a vague name for harassing phone calls in the industry. Manager Feng introduced that making harassing calls through the Rongying communication outbound call system can hide the real calling number to prevent complaints.
Rongying Communications Sales Department Manager Feng: In this case, we circumvented the operator to detect the call record.
With such circumvention technology, Rongying Communications charges companies that make harassing calls about 0.1 yuan per minute. A large number of harassing phone calls have brought a huge amount of telephone bill income to Rongying Communications.
Rongying Communications Sales Department Business Manager: Our net phone bill revenue is almost 100 million yuan a year. We serve more than 20,000 customers.
Reporter: More than 20,000? How much can Mobai account for?
Rongying Communication Sales Department Business Manager: How to get 80% up, basically make strange phone calls.
Ronglian Qimo, a subsidiary of ronglian cloud communications, a listed company, is also providing outbound paging systems and lines for telemarketing companies. Here, too, harassing phone calls are vaguely referred to as "mobai."
Ronglian Qimo Business Manager: If it is a strange visit, we also have a line of strange visit. Running more than 30,000 customers on our platform, there must be some of them doing Mobai.
Ronglian Qimo has introduced another technology for companies that make harassing calls to respond to user complaints and supervision.
Ronglian Qimo Business Manager: You can only apply for the kind that has a number pool, which has dozens, hundreds, and thousands of numbers. Every time you make an outbound call, you'll show a number inside.
Reporter: The number that appears every time is different, right?
Ronglian Qimo Business Manager: Yes, and it may have been used by others before.
As the investigation deepened, the reporter found that around the black industry of harassing calls, in addition to these companies that specialize in providing outbound call systems, there are also people providing big data support for harassing calls.
Hangzhou Is a fishing company located in an ordinary office building in Gongshu District. General Manager Tang of the company has been in the data industry for several years, and experience has taught him that this black industry often shuffles.
Tang General Manager of Hangzhou Yiyu Information Technology Co., Ltd.: Although we are not big, we are relatively early in this industry. We're not going to make it big, because there's no way this industry can make you do it big. Do it a lot, and the worse you die.
The company's technician logged into the background of a call system opened by a decoration company through the Hangzhou Fishing House, which recorded the recording of a decoration company making marketing calls to users.
Hangzhou fishing system background recording: Hello, my side is the official customer service platform, this side of the attention to you have browsed the decoration information, want to ask us this side is the decoration needs, right?
General Manager Tang introduced that these users have recently browsed some furniture and decoration websites with their mobile phones. Although the user does not leave a phone number, they can call the user directly through their system.
General Manager Tang of Hangzhou Yiyu Information Technology Co., Ltd.: As long as he has browsing behavior, such as you browse this thing today, you have not looked or how, nor left a phone, you can call this user.
Reporter: Just browse the web?
General Manager Tang of Hangzhou Yiyu Information Technology Co., Ltd.: Yes.
The reporter is puzzled that the user browsing the website did not leave a mobile phone number, how can this system dial the user's phone?
General Manager Tang of Hangzhou Yiyu Information Technology Co., Ltd.: Is there a MAC number (mobile phone identification code) corresponding to everyone's mobile phone? At this time, in fact, your number can be matched to this mobile phone. This phone is naked, you know what I mean?
Companies that make harassing calls use such data to charge fishing companies a fee of three dollars per strip. In order to further verify, the reporter also opened an outbound call account. Subsequently, the Hangzhou Fishing Company issued the recent website user data that the reporter wanted to know, and although the mobile phone number was encrypted, it could indeed be dialed.
It seems that as long as the user browses the website, the fishing company can call the corresponding sales call to the user through this system.
General Manager Tang of Hangzhou Yiyu Information Technology Co., Ltd.: To put it bluntly, many of us talk about it, in fact, it is a violation of the law, a bit of a violation of the nature.
Accurate big data involving users' Online behavior has become a feast for the black industry of harassing phone calls. The reporter's investigation found that many companies are engaged in similar business.
Business Manager of Zhengzhou Luqian Network Technology Co., Ltd.: All those who have visited this group can pull out and be real-time. Today you get yesterday's, the next day to you, all the data is given to you every other day.
Multiplying Information Technology Co., Ltd. Business Manager: It can be based on the user's range of activities.
Reporter: Is it through the mobile phone number that he knows the scope of his activities?
Business Manager, MultiplyIng Information Technology Co., Ltd.: Yes.
Qingniu Business Manager: Accurate big data, that is, this business matches his phone number. For example, where did he browse and search for this keyword, how do I reach the customer's phone number?
In addition to using encrypted numbers to make harassing calls to users, some companies can also obtain the clear code mobile phone numbers of users who use mobile phones to access the Internet through technical means.
Business Manager of Multiplication Information Technology Co., Ltd.: Users who crawl my own advertising page, in fact, we can see the customer number in the management background. The price is a bit high, 15 yuan a piece.
Zhengzhou Green Lead Network Company, on the other hand, claims to be able to obtain the clear code mobile phone numbers of almost all website users logged in.
Business Manager of Zhengzhou Luqian Network Technology Co., Ltd.: The time the customer opens this page with his mobile phone, he is acquired.
Reporter: Is the phone number?
Business Manager of Zhengzhou Luqian Network Technology Co., Ltd.: Yes, whether he buys smart homes or clothes, bags, perfumes, computers, or home appliances, he can get it.
Reporter: How much can you run in a month with this kind of data?
Business Manager of Zhengzhou Luqian Network Technology Co., Ltd.: There must be a million bars a month.
In order to confirm that what he said was not false, Manager Zhao provided the reporter with the mobile phone number of the user who recently logged on to a large shopping platform, all of which were clearly coded, and the reporter verified some of the phones.
Reporter: Hello, have you recently used a shopping platform?
Lady 1: Yes, it has always been useful.
Reporter: Hello, have you recently bought something on a shopping platform?
Lady 2: They all like to buy things on a shopping platform.
Manager Zhao particularly stressed that it is illegal to buy and sell the mobile phone number of users with clear codes. Such a data business must be communicated through a chat software that leaves no trace, and transactions can only be made with virtual currency.
Reporter: How to give money, how to give data? In what way?
Business Manager of Zhengzhou Luqian Network Technology Co., Ltd.: Money is generally a virtual currency.
Reporter: Virtual currency? So how do you give me the data?
Manager Zhao: Through the software that you just said.
Big data such as user behavior on the Internet has been abused in this way, and has brought about endless harassing phone calls that seriously affect the tranquility of our lives.
