The court found both individuals guilty of violating the Special Act on Prevention of Telecommunications and Financial Fraud and Refund of Damages. Prosecutors explained that Duong and Pham first made contact with the voice phishing scam ring in October last year. The ring recruited both via a Telegram open chat room. The ring’s organizers told Duong and Pham that they were to receive the proceeds of voice phishing scams in Korean won. The duo was then instructed to use this money to buy USDT, which they then sent to a crypto wallet held by a member of a voice phishing gang who was residing in Vietnam. The ring paid both Duong and Pham commission fees of 50,000 won ($36.44) to 100,000 won ($72.88) per 10 million won ($7,288) worth of USDT they sent.

The ring’s employees called people pretending to be credit card delivery workers, insurance company employees, National Tax Service staffers, and even public prosecutors. They usually told potential victims that they were calling to check the safety of their bank accounts. The ring used a range of money laundering techniques, using other accomplices from Uzbekistan and Vietnam. The judge said that the court had not handed out a harsher sentence because neither of the defendants had criminal records in South Korea. But Lee added: “Even if the defendants did not orchestrate the crime, they must be severely punished. They played an essential role in the crime, acting as intermediaries. They have also not made any special efforts to help compensate the victims for the damages incurred.” USDT-related crime is on the rise in South Korea, as the coin’s popularity in the nation continues to grow.
