PANews reported on November 22 that according to official news from Upbit, the exchange has refunded about 8.5 billion won to 380 users who were victims of telecommunications fraud. Dunamu, the operator of Upbit, used the real-time abnormal transaction monitoring system (FDS) to freeze the funds involved, and cooperated with the Seoul Metropolitan Police Agency to identify and contact the victims who did not report the case to complete the refund. The refund includes 5 billion won in February and the latest 3.5 billion won.
