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

The Financial Supervisory Service (FSS) has identified 19 IP addresses in the United States, Japan, and 10 other countries that were utilized in a series of hacking attacks against Korean financial institutions, according to industry sources on Tuesday. Several prominent banks, such as Hana Bank, KB Kookmin Bank, and Shinhan Bank, experienced consecutive breaches of customer data during these cyberattacks last week, raising fears that additional firms may have been affected.

The FSS has zeroed in on IP addresses from 12 different countries as potential sources of the AI agent-driven attacks. In response, local financial firms are acting swiftly to evaluate their security measures to prevent further hacking attempts. President Lee Jae Myung urged a comprehensive investigation into the incidents over the weekend.

On Thursday, Shinhan Bank announced that the personal data of approximately 25,000 customers, including their names, phone numbers, and annual incomes, had been exposed in the breach. Sources indicated that the bank was targeted by the hackers.
