Hackers used a Chinese AI agent tool in attacks on South Korea’s biggest banks, stealing personal information of approximately 68,000 people, Seoul officials said.
Seven financial firms hit: Shinhan, KB Kookmin, Hana, BNK Busan, Yegaram Savings Bank, Welcome Savings Bank, Hyundai Capital. National Police Agency cyber terror unit opened formal probe.
Investigators found traces of ARTEX AI, an open-source Chinese-developed penetration-testing tool, on attacker IPs. President Lee Jae Myung said AI appears to have been used; officials confirm humans directed attacks.
Shinhan disclosed ~25,729 affected customers. FSS identified 28 distinct attacker IP addresses and asked firms to complete security checks by Thursday.
