South Korea probes bank breaches amid suspected AI-powered attacks
South Korea is investigating confirmed data breaches at Shinhan, Kookmin, and Hana banks amid suspected AI-assisted attacks.
South Korea's Financial Services Commission held an emergency meeting after cyber incidents at major banks and confirmed a data breach at Shinhan Bank. Local reports say Shinhan exposed details of about 25,000 customers and KB Kookmin Bank leaked credit-card information for 119,000 clients, while Hana Bank suffered a limited compromise of a sales-support system. Authorities ordered inspections of externally accessible systems, tighter access controls, and rapid sharing of threat information with KISA. Yonhap reported that a server used in the attacks referenced ARTEX AI, an open-source agentic penetration-testing system, but banks and regulators have not confirmed that tool was used.
