Group-IB notified the incident to the national CERTs and financial organizations in South Korea and the U.S. and are working closely with its partners in these countries to investigate on the incident.

Shawn Tay, Senior Threat Intelligence analyst of Group-IB, concluded, “Even though, there is not enough information in this dump to make online purchases, fraudsters who buy this data can still cash out stolen records. If a breach is not detected promptly by the card-issuing authority, crooks usually produce cloned cards (white plastic) and swiftly withdraw money via ATMs or use cloned cards for illicit in-person purchases.”
