South Korea’s Financial Services Commission held the sixth meeting of its Frontier AI Response Task Force on the 16th at the Government Complex Seoul annex to review security and consumer-protection frameworks across the electronic payment gateway (PG) sector. Chaired by Yoo Young-joon, Director General for Digital Finance Policy, the meeting included the Financial Supervisory Service, the Financial Security Institute, industry associations, two card companies and four PG companies. PG firms connect financial institutions and merchants while processing sensitive information such as names, dates of birth and card details, leaving weaknesses vulnerable to data leaks, fraudulent transactions and cascading disruption across the payment ecosystem. Authorities said attacks increasingly exploit merchants with weaker security as indirect routes into PG networks, requiring monitoring and response systems that cover external touchpoints. Participants also reaffirmed data minimization and urged PG companies to prepare for AI-assisted phishing, malware modification and vulnerability scanning. The FSC will strengthen rapid information sharing with card issuers, which will register compromised data in Fraud Detection Systems and monitor related accounts and transactions. Consumer protections including prompt notification, card reissuance and full compensation for damages are to be implemented alongside the initial response. The FSC also plans to encourage participation in government security programs and has expanded emergency network-separation regulatory relief to electronic financial business operators.
