#One. Mr. A, who lives in Busan, started working last year after receiving a text message asking for a part-time job as a purchasing agent. The way to make money was simple. If you purchase an item on a shopping mall site instead, 10-20% of the profit is added to the cost of the item. Instead, you had to recharge your points with cash at the shopping mall site and then purchase designated items. At first, I thought it was trustworthy because if you purchase a small amount of goods, you will get the money and profits back. However, when the scale grew bigger and tens of millions of won were charged, something happened. Suddenly, access to the site became impossible, and Mr. B, who introduced himself as a shopping mall employee, disappeared.

#2. Mr. C, who lives in Ilsan, Gyeonggi Province, received a text message saying he would receive 20,000 won if he completed a movie survey last month. After simply answering the question, ‘What genre do you like?’, 20,000 won was deposited into my account. In response to a text message asking, ‘Do you want to do more work?’, Mr. C replied yes and was immediately invited to the Telegram room. Mr. C was introduced to the idea that if you book a movie ticket on a certain site, it will be returned with an incentive. He thought he was being deceived and the 100,000 won he sent was returned as 130,000 won. The scale grew bigger and bigger, and when Mr. C deposited 10 million won, the other party disappeared.

Voice phishing techniques are becoming more sophisticated. In the past, people impersonated employees of financial institutions and investigative agencies to extort money, but recently, they extort people’s money by pretending that it is a part-time job that allows them to earn money easily and conveniently. The method is to first build trust by giving money as promised, then increase the amount, steal it, and then disappear.

There are also cases where victims who have suffered losses through stock investment are deceived by impersonating a loss compensation team and saying, ‘If you make a deposit, we will refund your investment losses in virtual currency.’ This is a case where a crime is committed by taking advantage of the psychology of a person who is in a difficult situation.

It has also been reported that messages containing a link to install a malicious app, such as a wedding invitation, delivery inquiry, or card payment approval text, are sent, or a malicious QR is added on top of a QR code attached to a public bicycle Ttareungi, causing the malicious app to be installed when the user scans the QR. Some people suffered losses worth 4.1 billion won after being deceived by the installed malicious apps and carefully planned scripts. This is the case of Mr. D, an office worker living in Seoul.

Mr. D recently received a call from an unfamiliar number introducing himself as ‘Prosecutor E of the Seoul Central District Prosecutors’ Office.’ The person impersonating Prosecutor E said that the bank account in Mr. D’s name had been used for a crime, sent him a photo of the complaint and his civil servant ID via KakaoTalk, and said he would complete the investigation through a summary investigation if he cooperated well. When Mr. D said he would cooperate, he received a text message saying he needed to install a security program, and when he clicked on it, a malicious app was installed. The malicious app was a program that not only allowed the criminal organization to view contact information and text messages stored on Mr. D’s phone, but also ‘forced reception and sending’. Even when Mr. D suspected voice phishing and called the Financial Supervisory Service, the call was intercepted and impersonated as an employee of the Financial Supervisory Service. Mr. D suffered a loss of 4.1 billion won in one month after being deceived by the saying, ‘You have to borrow and withdraw money to find out if the person in charge of the name was involved in the crime.’

The methods by which voice phishing criminal groups impersonate prosecutors have also become more sophisticated, as seen in Mr. D’s case. In the past, people would impersonate themselves as ‘prosecution prosecutors’ over the phone, but these days, they deceive people by sending forged documents in the name of the prosecutors’ office, prosecutors’ identification cards, or photos of prosecutors’ confiscated boxes. There are also cases where the actor acts while wearing a legal uniform and making a video call.

A prosecution official said, “If an unverified party asks for money for any reason, you must hang up the phone and carefully check the authenticity.” He added, “You must not carelessly install a link sent by an unverified party. If you have installed a malicious app, “As a member of the organization can take over the phone using the ‘Kangsoo Kangbal’ function, the authenticity must be confirmed using other means of communication,” he said.

As the government responds to intelligent voice phishing crimes by mobilizing government-wide capabilities, the amount of damage and the number of incidents are decreasing. According to the National Police Agency, the damage from voice phishing crime increased from 247 billion won in 2017 to 774.4 billion won in 2021, and after the launch of the ‘Voice Phishing Crime Government Joint Investigation Team’ at the Seoul Eastern District Prosecutors’ Office in July 2022, it increased to 543.8 billion won in 2022 and 447.2 billion won last year. decreased to

The number of cases was around 30,000 for four years from 2018 to 2021, but then decreased to 21,832 in 2022 and 18,902 last year.

On the front line of investigation, there are voices saying that due to the nature of voice phishing organizations that operate as branch organizations, it is difficult to identify members, and that international cooperation to apprehend overseas call center organizations that directly commit crimes takes a significant amount of time.

Kim Soo-min, head of the voice phishing crime joint unit, said in an interview with Money Today, “Although the call center organization is located overseas, it eventually connects with a voice phishing organization operating in Korea to contact domestic victims and swindle the victims’ money.” “While investigating, we will increase the possibility of arrest by simultaneously issuing arrest warrants, placing wanted by Interpol, and expunging passports for specific overseas gang members,” he said.
