Recently, Mr. Cao, a citizen, encountered an annoyance. Since April 16, he has frequently received calls from strange numbers in other places. After answering, no one spoke. If he doesn't answer, he will hang up automatically after a few seconds, and then call back, so Mr. Cao has to turn off his phone. I thought there was something wrong with the mobile phone, but then he received a short message asking for money, saying that he could cancel the call as long as he paid.
On 2 1, the reporter learned that this is a software called "Call You to Death". Because most of the software uses network phone numbers, it is very uncertain and difficult to shield. Citizens must pay attention to protecting privacy in their daily lives.
The phone suddenly kept ringing.
On the morning of April 16, Mr. Cao, who is engaged in sales, received a call from a strange number in other places. But after answering the phone, no one spoke for a long time and had to hang up. A few minutes later, Mr. Cao's mobile phone rang again, and it will automatically hang up every second or two, and then call again every few minutes.
"This mobile phone number is usually used for work. At first, I thought it was a customer or friend who changed his mobile phone number and joked with me, but when I called back, I was prompted that it was empty. " Mr. Cao said that in the next few days, he frequently received similar calls. He tried to block a number with mobile phone interception software, but every time he blocked a number, another number continued to enter, and sometimes the attribution of the number would show that he was from the United States, Canada and other countries. At most, he was harassed more than 400 times a day.
Repeated harassing calls not only made Mr. Cao's mobile phone unable to answer other calls, seriously affected his work, but also caused the power of his mobile phone to drop rapidly. Mobile phone batteries, which could last more than two days, now need to be recharged in less than three hours.
A few days later, on 18, Mr. Cao received a short message. "The general idea is that I was harassed because I was included in the' call you to death' software. As long as I spend 200 yuan money, the other party can stop harassing me and threaten me to keep calling if I don't pay. " Mr. Cao said that in desperation, he had to temporarily shut down this mobile phone.
"Call you to death" software
Subsequently, the reporter used the internet to search for "call you to death" software, and dozens of download websites popped up, which can be downloaded for free. When using, most websites provide free time-limited experience software. After the limited-time experience is over, the other party will ask the user to pay, and some software registration needs to be recharged to use, generally only a few cents per minute.
The reporter downloaded several "call you to death" software and found that the interface and functions of the software are almost the same. You can set the number to be called, the duration of continuous call, call speed, etc. Some software even has the function of "randomly displaying numbers", that is, the calling number and calling place displayed in each call are random. If the public calls back according to the number displayed by the caller, it will prompt that it cannot be connected.
The reporter enters his mobile phone number in the operation interface of a software, sets the call duration and interval, and then starts the task. Soon, the mobile phone rang and the words "Incoming number not displayed" were displayed on the screen. In the next five minutes, the phone received several calls in succession, and it didn't stop talking until the stop button on the software was clicked.
360 mobile phone security experts proposed
Then the reporter went to the 360 Security Center, hoping that experts who focus on Internet security can solve such problems from the source.
Experts suggest that it is necessary to install mobile guards on smartphones to intercept harassment and fraud. For this kind of "calling you to death" software, you can also set the non-address book number rejection and one-click setting to avoid harassment.
