Yuanta Securities Prevents Voice Phishing Losses with Enhanced FDS

Efforts to Protect Customer Assets
and Prevent Financial Losses

On April 24, just over a month after Yuanta Securities upgraded its Fraud Detection System (FDS), the company prevented customer losses of 365 million KRW due to voice phishing. In April alone, the enhanced FDS blocked four cases of telecommunication financial fraud, preventing losses totaling approximately 500 million KRW.

The advanced system enabled the detection of suspicious cases, and prompt, proactive responses from the Financial Consumer Protection Team and branch employees helped prevent customer losses.

The FDS is a system that comprehensively analyzes various data, such as customers' device and access information and other transaction data, to detect suspicious transactions and block abnormal financial activities.

Since March 14, Yuanta Securities has been operating an upgraded FDS to protect customer assets and minimize losses from telecommunication financial fraud and electronic financial accidents, including voice phishing and illegal investment chat rooms.

Based on abnormal transaction monitoring detection rules that consider major fraud cases, the system analyzes correlations by transaction type and user type from collected data to monitor abnormal financial activities 24 hours a day, 365 days a year. When abnormal transactions are detected, withdrawals, remittances, and loan executions are restricted to prevent customer losses.

Lee Moonhan, Head of the Financial Consumer Protection Division, stated, "Prosecutors, investigative agencies, and public institutions never request fund transfers. In the event of a similar case, please verify directly with your financial institution or contact the Financial Supervisory Service call center." He added, "Yuanta Securities will continue to upgrade its FDS and respond actively to protect customer assets and prevent losses from illegal financial fraud."
