Under the guise of "repairing broadband", a suspect was arrested for installing a "black box" specially designed for electronic fraud.

On May 12, according to a report by the Beijing Evening News on Saturday, police from the Huajiadi Police Station of the Chaoyang Public Security Bureau received reports from resident Uncle Wang that a few days ago, "staff" from the "Broadband Company" came to their home. After repairing the broadband network at home, the landline phone at home no longer works.

After careful inspection, the "culprit" that caused the landline at Uncle Wang's home to be unusable was actually a black "set-top box" style device at the phone line terminal. According to reports, the device is a voice gateway device called VOIP, which can convert overseas network signals into local fixed-line signals. It will automatically enter continuous working status when connected to power. Since it is installed in residents' homes, it is very hidden.
After the above-mentioned equipment is installed in the victim's family, the network cable will be quietly used by the electronic fraud gang to engage in fraudulent activities. After VOIP signal conversion, when other (Beijing) citizens receive overseas fraud calls, they will be displayed as landline numbers starting with 010, thus reducing the vigilance of the fraud targets. In the end, the day after Uncle Wang reported the situation, the suspect appeared again in the jurisdiction and tried to provide "door-to-door network maintenance services", but was caught by the police on the spot. It is reported that other members of the gang will pretend to be customer service personnel of broadband companies and make random calls to make appointments for door-to-door services for reasons such as free bandwidth increase or signal maintenance. After the appointment was successful, the suspect was contacted, informed of the installation location, and instructed to come to the door for installation. Within a month, the suspect installed dozens of VOIP devices in accordance with the "instructions" and made nearly 10,000 yuan in profit. Most of the victims were elderly people. The suspect has been criminally detained by Chaoyang police. Local police remind that if you receive a call from broadband customer service personnel or a staff member directly knocks on the door to provide free services on the grounds of signal maintenance, network speed upgrade, etc., please call the official customer service number as soon as possible to conduct business.

According to previous reports, a similar form of telecommunications fraud also appeared in Shanghai in December last year: criminals installed new signaling equipment in the name of door-to-door network maintenance, causing landlines at home to become unusable. The local police discovered that the "black set-top box" on the phone line in the victim's home was actually a GOIP device installed with a router and data card. It can convert overseas network signals into local fixed-line signals. After being powered on and connected, it can automatically enter continuous work. state. Similarly, overseas calls will be disguised as Shanghai landline numbers (starting with 021).
