Large Data tracking: Super Four spam message from pseudo base station

Mobile phone harassment phone and spam has become a public nuisance, who is the harassment? What is the most alarming information about harassment? A recent report on the study of harassment information in the first quarter of this year has given precise answers to these questions by using large data. The report found that the current rate of spam from pseudo-base stations increased significantly, accounting for more than 40%. This shows that through mobile phone real-name system and operator control and other methods to control the garbage information harassment, the effect is increasingly limited.

The complete feedback of tens of millions of users in data carding analysis

Unlike the "sample sampling" method used in conventional research, the report's data come from the full and comprehensive feedback of millions of users. The report publisher is the hot call Firewall app "contact number Assistant". Every day, its users will be received by the harassment calls and spam messages marked, submitted to the touch, so as to form a harassment number "blacklist encyclopedia." In more than a year of time, after a large amount of user feedback to comb and analysis, the contact treasure finally released the report.

The report found that in the first quarter of this year, more than 22 million harassment phone numbers were marked, up 69% per cent, and the main harassment calls were business sales, accounting for 44%, followed by malicious harassment and real estate intermediaries, representing 22% and 20% respectively. Of all harassing calls, 68% came from a fixed number and 32% from a mobile phone.

In the spam message, this year, the total number of users reported more than 66 million, advertising sales, operator business, fraud message is the main three categories of content, respectively, accounting for 44%, 30% and 18%. Among them, the most noteworthy is the trend of pseudo base station. The report found that the proportion of messages reported by users this year was as high as 41% from pseudo base stations; in other words, over 10 million spam messages are not sent through the carrier network on average every month.

Pseudo-base station can be arbitrary camouflage number, highly deceptive

The difficulty of regulation is also reflected in the distribution of spam message "birthplace". According to the report, the country's largest number of junk text messages sent in the provinces of Guangdong, Hunan, Zhejiang, Shanghai did not enter the top ten. This shows that for the local mobile phone number, Shanghai control is relatively in place. But in the most active provincial area of the pseudo base station, Shanghai is ranked six, the top three are Henan, Beijing, Shandong.

The pseudo base station can only send information to the mobile phone users around two hundred or three hundred meters. Therefore technically, it does not exist "across the province to send" the possibility, but on the other hand, the control of pseudo-base station criminals can easily disguise the text message to include the bank, public security, such as the number of any number, so the deception is very strong.

According to the report, whether the phone or text messages, Beijing, Shanghai and other first-tier cities are "hardest hit", but a noteworthy trend is that the "hardest hit" is now accelerating to the second-tier cities spread.

Spam messages not only repeatedly dozen, but also put on the "High-tech" coat, using the pseudo-base station this new form of mass transmission.

High density, camouflage strong pseudo base station there is huge profiteering space, a device can recover costs in a few days, and can counterfeit any mobile phone number sent, potential harm unimaginable.

Because of the existence of pseudo base station, the future will be difficult to simply through the mobile phone real name and other conventional methods of spam messages and all kinds of harassment information supervision.
