New vest: harassing phone 400 to 9521 can choose to go to the phone number

After a nap, I picked up the phone and came up with “Do you need insurance?” “Does the garden house need it?” In the face of harassment calls, people can't help but feel helpless. Recently, a number of agencies have detected that harassing calls beginning with "9521" have grown wildly in recent months. Industry insiders stated that telemarketing could not disappear within a short period of time, and harassment of calls would not stop. Where did the harassment call come from? Who should supervise the harassment of telephone calls? What can we do other than pulling black and shutting down?

The "400" segment is a service line provided by telecom operators for enterprises. It aims to build a communication platform between consumers and businesses and was once considered by consumers as a symbol of corporate reputation and strength. However, afterwards, quite a few 400 numbers have become mobile phone users shunned, harassed, and even scam phones. In 2016, the Ministry of Industry and Information Technology began to vigorously rectify 400 telephone calls, and 400 non-real-name telephones were forcibly shut down. With the cooperation of the operators, the management of the 400 harassment calls has been effective.

However, in a recent experience test, reporters found that VoIP operators can provide services such as dialing numbers to select any number of people randomly or randomly. The number broadcasted by these VoIP phones cannot be dialed back and cannot be tracked, and it is easy to use. It became a breeding ground for harassing phone calls. Some of the numbers provided by these VoIP operators have been marked as harassing calls.

In this regard, independent telecommunications analyst Fu Liang analyzed in an interview with reporters that the changes in the environment make many companies make phone calls over the Internet. On the one hand, as the country strengthens the governance of harassment calls, the cost of corporate telemarketing is getting higher and higher; on the other hand, with the development of technology, many companies have begun to use Internet telephony for outbound calls. Coupled with the cancellation of long-distance fees, many companies started dialing in different places, which also increased the difficulty of supervision.

Internet phone provides hidden number service

Some netizens spoke on the Internet that they frequently received harassing telephones beginning with the 9521 telephone. The telephone sources are all over the country. The contents involved in various industries such as marketing, real estate agency, insurance, and wealth management.

In order to understand the source of the harassment, the reporter tried to call back the phone that had been received before 9521. However, without exception, the voice prompt was “I'm sorry, the number you dialed does not exist” or prompted to answer the call.

Tencent mobile phone butler security expert Yang Qibo said in an interview with reporters that there are mainly two kinds of situations that cannot be dialed. The first type, the number can be set whether to support callback, if the setting can not call back, the user can not directly dial; second, if it is to change the phone number, it will usually have special characters, basically all false numbers, Callbacks are generally empty numbers. Calls of this type cannot be made directly. So you want to know if this type of call is a fraudulent call. You can confirm it by dialing back.

Since the caller information could not be retrieved through callback, combined with the above mentioned experts mentioned that many harassing calls began to use Internet telephony, the reporter then decided to download some Internet Phone App to actually experience.

Through the use of Bao search "Internet phone", the reporter selected five software installation registration and experience, namely Alibaba phone, cloud dial network phone, micro-telephone, UUcall, there is a call through the Internet.

During the software setup process, the reporter noticed that in the selected five Internet phone softwares, it was possible to choose to set the "exchanging phone number" function, that is, after selecting this function, when the user dials the phone, the other party's phone The user's real number can be displayed. This also means that if the user does not turn on the "exchanging number" function, when the user is using a network phone, the other party's mobile phone does not display the number or only the network routing number.

It is worth noting that if you want to turn on the "exchanging phone number" feature, your microtelephony phone needs to purchase "precious privilege", UUCall needs a fee of 5 yuan per month, and some are free, if you have access to Internet telephony and cloud dialing. Internet phone; Alibaba phone is suspended for this function.

In the process of experience, reporters also discovered that some Internet phones have made further enhancements to outgoing call numbers. In the micro phone, the user can select one of the seven numbers provided by the client as his own outgoing call number. The seven numbers are distributed in six cities including Beijing, Shanghai, Guangzhou, Shenzhen, Chengdu and Xi'an.

Since the Internet phone itself is simple and easy to use, most people can download and use it, plus various enhanced phone numbers provided by various Internet phone operators. These factors combine to provide a warm soil for the growth of Internet harassment calls. .

Part of the number was reported

Can these ISPs provide designated numbers, such as the “9521” section of the recent surge in harassment calls for outbound calling services? With this question, the reporter consulted the customer service of the micro phone as a user.

The micro-telephone customer service replied that there are currently three types of local, slightly nicknamed, and random number numbers, and there is no paragraph number 95 display.

In the experiential test, the reporter selected a "random number" for the other mobile phone through the micro phone, and the name of the number received by the other party was displayed as "Guizhou Renhe Nianfeng Wine Co., Ltd.".

When the reporter tried to use another Internet phone software to make a call, the call interface of the other party showed that the place of attribution was Shandong Qingdao, and 50 people had been marked as harassing phone calls. This shows that out of the "outgoing display" numbers provided by the Internet telephony software, some of the numbers were used by companies for telemarketing. Users and mobile phone security software have already marked and identified this number.

Why does the Internet phone hide the user's real number, and they provide the outgoing number that the user chooses? Song Hongsheng, vice president of China-Micco Communications, said that regardless of which phone software is used, the Internet phone must have one or more access points if it wants to access the local phone network. This access point is equivalent to an address in the basic communication network. If it is legal, it may be assigned a number or a group of numbers. In the case of a number assigned to a user, the user dials out of the software through this software, and the fixed number may be the only one that receives the call. If it is a group, he is likely to provide the user with a random number.

Yang Qibo said that the cost of harassing phone calls is not high, and that there are also special software sales on the Internet. Fraudsters only need to pay for services through a website that offers services, such as recharging tens of dollars. With hundreds of downloads, you can use the Internet phone software you downloaded to use the Internet to dial numbers. However, this type of number change has nothing to do with the recent harassment of specific numbers.

"9521" harassing phone surge 800% how to root out

In recent years, telephone harassment has become a “public hazard”, and all kinds of mobile phone harassment information has been irritating. A large number of sales, decoration and mortgage loans have become the main force. According to data provided by various agencies, the recent surge in harassment calls from the “95” segment, in particular with the beginning of “9521,” indicates that some people began to focus on using this number to carry out targeted sexual harassment.

In 2016, in order to combat phone harassment and telephone fraud, the Ministry of Industry and Information Technology requires all basic telecom companies to conduct investigation and clear-up of voice lines and 400 phones, and vigorously rectify and standardize key telecommunication services. After centralized management, the 400 phone harassment fraud situation has improved. However, just like the "playing the gophers" game, the 400 phone was just suppressed, and "9521" just started.

Although the harassment of the telephone number “9521” was hot, Mr. Song Hongsheng, Vice President of China Wheat Communication, said in an interview with “Daily Economic News” that the outbreak was only a phased one. Song Hongsheng believes that as long as the basic operator can investigate in the basic communications network where the network harassment calls are accessed from, it can be targeted to do some effective measures.

Telephone marketing still has a living soil

The data released by the TouchPal phone shows that the number of harassing calls at the beginning of “9521” has grown drastically in recent months from less than 2.5 million in March to 20 million in May, an increase of up to 800% (eg, Right). The scope of these harassment calls involves the entire country. Telephone content includes loans, wealth management, marketing, insurance, and intermediary services. TouchPal data shows that the current harassment telephone area beginning with 9521 is mainly distributed in Guangdong, Shanghai, Zhejiang, and Jiangsu. The total area of ​​these areas accounted for 50% of the 9521 harassment calls.

Tencent mobile phone butler security expert Yang Qibo also gave similar data in an interview: The number of harassment of “95” type numbers from April 2017 to now has increased fivefold, and the harassment ratio has increased from 10% to the present 30. %, and it was mainly due to harassing calls that started with the “9521” used for call center service access. With the number of "9521", the number of harassment has increased by 10 times since April, and the harassment ratio has increased from 80%. The number is now basically harassing. Explain that harassment elements began to focus on using this number for targeted harassment.

Compared with popular new media marketing and social marketing, telemarketing, as a traditional marketing tool, can hardly establish trust between buyers and sellers. When people receive unsolicited marketing calls, there is basically a kind of resistance and resentment from within. Why is there such a "primitive" way for companies to adopt telemarketing?

Independent telecommunications analyst Fu Liang said in an interview with reporters that different products have different characteristics and different marketing tools also have their own characteristics.

Fu Liang believes that different tools, different product characteristics, and different user preferences determine what kind of marketing the company adopts. The advantage of telemarketing is that it is peer-to-peer. If companies can find accurate users, the success rate is still high. “Letters say that many people think that the SMS business has been declining. It is actually wrong. From the beginning of this year, the decline in the number of SMS messages has been very small and basically does not fall. For example, an e-commerce campaign has come in the past two days. You Previously purchased products on the above, will now send you some promotional information, these methods are actually very effective."

According to Fu Liang, the most popular type of telemarketing is the company's return visits to customers, and the other is the use of real estate, loans, financial management and other industries to promote products, and many of these species are on the edge of the law. The gray zone is even illegal.

Fu Liang said that Internet marketing and the characteristics and product features of these companies are not very consistent, which is why these companies still adopt marketing methods. Telephone marketing cannot disappear in a short time, and harassing calls will not stop.

Anti-harassment calls require operators to take the initiative

In order to combat harassment and fraudulent phone calls, the Ministry of Industry and Information Technology released a series of documents in 2016 that require registration of true identity information of telephone users to ensure that the real-name rate of all telephone users reaches 95% or more by December 31, 2016. June 2017 All telephone users have registered their real names 30 days ago.

On November 7, 2016, the Ministry of Industry and Information Technology released the "Implementation Opinions of the Ministry of Industry and Information Technology on Further Preventing and Cracking Down on Communication Information Fraud", vigorously rectify and standardize key telecommunication services, and strictly enforce new users' online access auditing and management. Strengthen business outbound management. And require all basic telecom companies to complete the troubleshooting of the voice line and 400 before the end of November 2016.

With the vigorous rectification of the Ministry of Industry and Information Technology and the cooperation of major infrastructure operators, the 400 harassment of telephone calls has achieved remarkable results, but the new number has emerged.

Song Hongsheng, vice president of China-Mex Communications, analyzed in an interview that an important reason for the outbreak of the 9521 harassment call was because the operator did not have a place in some places.

"These harassing calls are sure to find some vulnerabilities where IP phones and basic communication networks are accessed. If it is a legitimate VoIP phone, it will be assigned to one or a group of numbers when the user uses it. When the user is using software When outgoing calls are made, the other party's mobile phone displays a fixed unique number or a random one of a group of numbers. However, the authority of this function is actually implemented through this entire basic network setting.” Song Hongsheng explained Road.

In response to the outbreak of the 952 telephone harassment, Song Hongsheng thought that this was only a phased one. "In a normal network environment, this kind of user is not allowed to define the number of outgoing numbers. Actually, the basic operator wants to troubleshoot, it should be able to quickly catch the source of the problem, and some processing will not happen. A similar situation occurs again."

What should I do for the user? Anti-harassment security experts said in an interview with Neutral Media that the recent proportion of “9521” harassment calls has increased sharply, but because some normal services have also taken this number, if all screening will affect the normal use of users, users are advised to use professional software. Interception. For harassment calls such as loans and finances, you can hang up directly; for calls such as “hit and ring”, remember not to call back to avoid unnecessary losses.

The solution

Apple "Accepts" Third-Party APP to End Spam SMS

For annoying harassment calls, some mobile phone users will install security management software and tag the calls as "harassment", "fraud", "home loan", etc., so that the same number can be directly linked to the next call. However, the number of harassing telephones is constantly emerging, such as the new number beginning with “9521”, which has surged recently.

It is worth noting that domestic mobile phone manufacturers such as Huawei and Xiaomi have built in mobile security protection systems to prevent harassment of calls and text messages. Since last year, Apple, which is relatively "closed" in the system, has begun to make up for this deficiency through "openness."

On June 6, at the Apple Developers Conference, Apple unveiled the new iOS 11 system. For the Chinese market, Apple added features such as QR code scanning and spam filtering, and provided open interfaces to support the ability of third-party APPs to help users identify and intercept spam. Last year, when the iOS 10 system was updated, a new harassment phone recognition feature was added to help users prevent fraudulent communications.

How to prevent harassment surge

Many people in Shanghai have reported that in recent days, mobile phones have frequently received various types of sales calls beginning with “9521” and “9516”, mostly promoting the surrounding houses and selling loan services.

The reporter learned from Tencent's mobile phone stewards that in the first quarter of this year, the number of harassing phone calls was 137 million times, which was 8.82% lower than the same period of last year, but the number of “95” type numbers has increased from April 2017 to now. Times, harassment ratio increased from 10% to the current 30%.

In this regard, Tencent mobile phone butler security expert Yang Qibo analyzed with reporters, 95 telephone is a direct management approval of the Ministry of Industry and Information Technology, does not belong to the local telecommunications operator management of special numbers, before the main bank, insurance and other special units of the special number . Like the 400 phone, the 95 phone can use the single function in the call center's "Technology Collection" to realize the unified national or local number access for businesses and realize IVR automatic voice service, intelligent traffic distribution, voice mail and public seat service. . The 9521 number is the number specifically for call center service access.

In addition, there are also a small number of “95**” telephone numbers that are basically allotted using the network change number software, but have nothing to do with the recent harassment. The feature of this type of number is that it can be specified to display a unique telephone number by dialing via a web phone that supports number transparent transmission.

“Transparent transmission is transparent transmission, which means that the transmission network is responsible for transmitting the services that need to be transmitted to the destination node irrespective of the transmitted services, while ensuring the quality of the transmission without processing the transmitted services,” said Yang Qibo.

Yang Qibo said in an interview with reporters that “95**” harassing calls are mainly based on counterfeit bank customer service scam calls because they are dialed out and the dial-out area is not too good to be located directly on the user’s side and only operates. The backend data of the business can be determined. The allocated time period is generally corresponding to the fraud time of the fraud. For example, on weekdays or in the afternoon of each day, when people are more lax, the fraudsters can choose this time to increase the success rate of fraud.

However, "the 95 numbers that begin with these numbers have more obvious characteristics than those of ordinary mobile phone numbers. In fact, they are more easily recognized by the system than ordinary mobile phone numbers. For example, the number of harassment numbers beginning with 9521 is above 99%, and the number of high frequency harassment numbers are Has been identified." Yang Qibo explained.

For the average user how to prevent harassment and exhalation of Internet telephony, Yang Qibo suggested that professional mobile phone security software can be installed to identify all types of harassing phone calls, fraudulent calls, and use such software to directly mark the problem phone and help more people. Stay away from fraud and harassment.

Apple continues to access third-party apps

The harassment and prevention of telecommunications has always been a matter of high morale, especially in China. From telephone to text messages, all kinds of harassment information emerge one after another.

According to Tencent’s mobile phone butler statistics, in the first quarter of 2017, users reported spam messages as many as 266 million, an increase of 35.42% year-on-year. Spam messages are mainly classified into advertising, fraud, and illegal. In terms of the proportion of types, the number of advertisement-based text messages remained the largest in the quarter, accounting for as high as 90%; fraudulent and illegal messages accounted for 7% and 3% respectively.

The reporter noticed that several major mobile phone manufacturers in China, such as Huawei and Xiaomi, will all have built-in mobile phone security protection in their systems to help users guard against harassment calls and text messages. iOS, which is one of the two most popular mobile phone systems in the world, is relatively closed to the Android system. However, it is deepening cooperation with industry partners to improve anti-harassment capabilities. Prior to this, Apple had been unable to effectively solve the problem of intercepting harassing calls and text messages because of its own system.

Apple began to bid farewell to the “closed” era from the iOS 8 version released at the 2014 WWDC Conference, and continued to open up some system interfaces to developers. In September 2016, one of the biggest highlights of Apple's online iOS 10 release was the opening of the call-recognition interface to support third-party security software for harassing phone calls.

On June 6th this year, Apple mentioned at its Global Developer Conference that it supports the ability to identify and block spam through third-party apps in newly upgraded systems.
