The phone clearly shows that it is a call-in number of a relative or friend or a government official, but the user of the phone unknowingly walks into a fraud trap designed by criminals. A few days ago, the Shanghai police discovered several criminal activities that used the phone to call the "any number" function and used a specific identity to engage in mobile phone fraud. The police reminded that such criminal methods are extremely confusing, and mobile phone users should be extra vigilant to avoid being deceived.

The so-called "arbitrary number display" (commonly known as "transparent transmission") refers to the billing users of some operators that use the function of modifying the number display so that the caller no longer displays the number according to the standard when dialing others' calls. The number is "any display number".

A few days ago, Mr. Liu, a citizen of Hangzhou, Zhejiang Province, received a call with the call number 0216XXXX110 (Shanghai Public Security Bureau switchboard number). The other party claimed to be a public security police and said that Liu ’s bank account was not safe and should be transferred to the “security” provided by him. Account etc. Mr. Liu called the Shanghai Public Security Bureau, only to realize that the other party was pretending to be a policeman and was cheating.

How can the telephone display the switchboard number of the public security organ? After investigation, the police found that the criminals used the "any number display" function of the Internet phone to make calls. In this case, the Internet phone line belonged to a Netcom company in Hangzhou, and it was the first-level agent Hangzhou's technology company that was responsible for the caller leasing business. The technology company leased Internet phone resources from users online and decentralized the modification of the main With the authority to call the number, the suspect can use the calling number modification function to set the calling number to the Shanghai Public Security Bureau switchboard number for fraud.

Coincidentally, not long ago, a unit in Shanghai received a call with the call number 1381158XXXX (Beijing mobile number). The other party claimed to be the secretary of the Beijing leadership, came to promote the business, and requested to speak with the leader of the unit. The answering unit suspected fraud, and immediately reported the case to the police. After investigation, the police found that the case also used the mobile phone "any number display function" to carry out fraud.

Recently, the Shanghai police discovered through work that there have been many cases of fraud using the mobile phone's "any number display" function. The crime is extremely deceptive, so that the called party cannot correctly judge the true identity of the caller by displaying the number.

It is reported that in order to attract customers, some operators will recommend and provide the "pass-through" function of the calling number to their customers. However, due to the uneven quality of some customers, operators have inadequate supervision of customers, resulting in the "pass-through" function being used by criminals. From a nationwide perspective, some operators still have a serious phenomenon of “arbitrary display of numbers” in order to earn their own performance profits.

The police reminded that in similar situations, the masses should be vigilant. They can call back the number shown on the caller ID to prove it, and report the problem to the public security organ immediately to avoid being deceived.
