PG Firms Initiate Joint Measures to Block Fraudulent Transactions Missed by Financial Institutions' FDS Systems

A security gap emerged where fraudulent transactions passing through financial institutions' fraud detection systems (FDS) were not blocked at the payment gateway (PG) stage, prompting the PG industry to launch joint countermeasures. The Financial Supervisory Service and Korea Fintech Industry Association inaugurated a 'Online Fraudulent Payment Response Coordination Committee' with major PG firms, the Financial Security Bureau, academics, and security experts. The committee aims to address structural vulnerabilities, including PG firms' inability to block fraud cases slipping past FDS systems, by establishing unified operational guidelines based on shared fraud detection experiences and response cases across firms.
