The actor targeted multiple Korean banks, including Shinhan Bank, KB Kookmin Bank, and Hana Bank, exposing clients ' personal data and credit card information, and causing system outages in some cases. The South Korean government reacted with an emergency meeting and calls for immediate security measures for critical IT systems. Security firm CrowdStrike confirmed the use of ARTEX AI, up until recently an open-source agentic penetration testing suite developed in China.
