Yuanta Securities Korea noted that it advanced the 'FDS (Fraud Detection System)' and prevented four cases of telecommunication financial fraud within a month on the 15th. The company prevented a customer loss of 365 million won due to voice phishing on April 24, totaling 500 million won in criminal damage prevented.
The FDS analyzes various data comprehensively, including customer device and access information and other transaction details, to detect suspicious transactions and block abnormal financial activities. Yuanta Securities Korea has been operating the advanced FDS since March 14 to protect customer assets and minimize losses from telecommunication financial fraud and electronic financial incidents such as voice phishing and illegal leading rooms.
The FDS at Yuanta Securities Korea conducts a 24/7 monitoring of abnormal financial activities based on detection rules considering major damage cases, analyzing correlations among transaction types and user types from the collected data. Transactions classified as abnormal financial activities are restricted, including withdrawals, loans, and more.
Lee Mun-han, head of the Financial Consumer Protection Division at Yuanta Securities Korea, said, "Investigative agencies such as the prosecution and public institutions absolutely do not request fund transfers, so in case of similar incidents, please verify the facts directly with the financial institution or contact the Financial Supervisory Service call center (1332)." He added, "We will continue to advance the FDS and actively respond to protect customer assets from illegal financial fraud."
