19 IP addresses behind recent hacking attacks against Korean financial institutions: watchdog

The Financial Supervisory Service (FSS) of South Korea has identified 19 IP addresses in the United States, Japan, and ten other countries as being utilized for a recent series of hacking attacks against Korean financial institutions, according to industry sources on Tuesday. Several prominent financial companies, including Hana Bank, KB Kookmin Bank, and Shinhan Bank, experienced back-to-back leaks of customer information following these attacks last week, prompting concerns that more firms may have been compromised.

The FSS has shortlisted IP addresses from 12 different countries, which are believed to have been employed for AI agent-backed hacking. In response to these incidents, local financial firms have rushed to reassess their security systems to protect against further potential attacks.

President Lee Jae Myung has called for a comprehensive investigation into the hacking attacks. On Thursday, Shinhan Bank disclosed that approximately 25,000 customer records were leaked, including personal details such as names, phone numbers, and annual incomes. According to sources, the bank was targeted by the hacking incidents.
