Korea’s financial regulator calls emergency meeting over suspected AI-driven bank breaches

South Korea’s Financial Services Commission chairman Lee Eog-weon held an emergency meeting with the financial industry after breaches at Shinhan Bank (25,727 customers), KB Kookmin, Hana, BNK Busan and savings banks including Yegaram (about 40,000 customers), saying AI use in the attacks could not be ruled out. Traces of a Chinese-language AI hacking tool were reportedly found, and the Financial Supervisory Service sent about 500 firms malicious IP addresses and ordered emergency checks.

Why it matters

Korean banks and lenders must complete emergency security checks, and the stolen loan data could make voice-phishing scams harder to spot, the paper reports.
