South Korea Financial Services Commission proposes anti-vishing AI platform for real-time sharing and analytics of suspicious account data

South Korea’s Financial Services Commission has set out measures to strengthen responses to vishing scams, centred on establishing a comprehensive anti-vishing platform that uses artificial intelligence analytics to support faster, more coordinated action across sectors. The platform is intended to address limits in firm-by-firm fraud detection, including limited exposure to prior cases, surveillance based only on individual scam-pattern analysis, and the absence of instant information sharing that can delay account suspensions and produce uneven response capability across firms. It would collect suspicious-account information from all financial sectors, telecom service providers, and investigative authorities, and operate two information streams: data for immediate sharing to enable rapid suspension of account activities and freezing of multiple accounts across sectors, and data for AI analytics. For the analytics stream, the Financial Security Institute would conduct AI-based pattern analysis on the latest vishing scams and share outputs to help financial firms block accounts in advance, telecom providers warn customers about suspicious phone numbers, and relevant parties strengthen preventive measures for customers deemed particularly vulnerable. The anti-vishing AI platform is expected to be operational by the end of 2025. The authorities also plan a broader overhaul of the anti-vishing response system spanning prevention, on-the-spot blocking, victim remedies, and public awareness efforts.
