According to Upbit's official news, the exchange has refunded about 8.50 billion won to 380 users who were victims of telecom fraud. Upbit operator Dunamu used the real-time abnormal transaction monitoring system (FDS) to freeze the funds involved in the case, and worked with the Seoul Police Department to identify and contact the victims who did not report to the police to complete the refund. The refund includes the 5 billion won in February and the latest 3.50 billion won.
