Police have caught a large number of people who smuggled, operated, and distributed a modified repeater of the calling number so that overseas Internet calls can be marked with a domestic "010" number.

The Busan Metropolitan Police Agency's Drug International Crime Unit said on the 20th that it arrested 101 people on charges of providing phishing fraud to a phishing organization (violation of the Telecommunications Business Act, etc.) and arrested 16 people, including a Russian national in his 20s.

From November last year to September, A and others are accused of disguising a repeater that converts the transmission number of overseas Internet calls into domestic mobile phone numbers as hard disks and installing and operating them in studios so that they can be used for phishing scams.

Internet calls sent abroad are usually marked as 070 and are not easily answered by ordinary citizens. As a result, overseas calls have been changed to domestic 010 numbers through the domestic calling number modification repeater and the USIM chip, which opened in Korea, and have been used for phishing scams and other crimes.

In February, police obtained information that a large number of USIM pieces were found in the drain of a one-room building in Busan, and after confirming that these USIMs were used in a phishing scam impersonating the prosecution, they launched an investigation. They supported phishing scams by dividing their roles into stages, such as supplying repeaters brought from overseas to Korea, installing and operating them.

The overseas general and secretive measures were Chinese nationals, and most of the members of the relay distribution and operation organization consisted of foreigners of Russian nationality, including Russia, Belarus, Kazakhstan, and Uzbekistan. It was found that they were recruited through the Telegram Russian job opening and job bulletin board.

The police confirmed the opening and transfer of USIMs used in the crime and arrested Koreans who provided USIMs in their names for a price of 60,000 won to 120,000 won each. In addition, during the investigation, they identified two equipment storage warehouses managed by these organizations, and seized 400 repeaters, 121 cannon phones, 5,256 USIM chips, and 848 other equipment, including routers, through seizure and .

A police official said, "Even if the calling number is displayed as 010, we should not conclude that it is a normal domestic phone call, but if you impersonate an investigative agency such as the prosecution and ask for remittance or cash delivery, you should stop the call and check it as an official information of the agency." "Even at the request of an acquaintance or friend, you should not open or transfer a USIM in your name in exchange for money or loans," he added. "We should be extra careful in that such USIM can be used as a tool for phishing scams."
