SEOUL - The country's financial watchdog has pinpointed 28 internet protocol (IP) addresses in the United States, Japan and 10 other countries used for a series of recent hacking attacks against Korean financial institutions, industry sources said Tuesday.
Several financial companies, including Hana Bank, KB Kookmin Bank and Shinhan Bank, suffered back-to-back leaks of customer information in recent hacking attacks last week, raising concerns that more firms might have suffered data breaches.
According to the sources, the Financial Supervisory Service (FSS) has shortlisted IP addresses in 12 countries, which are presumed to have been used for the artificial intelligence (AI) agent-backed hacking.
Local financial firms have been in a hurry to check their own security systems to fend off any additional hacking attempts.
Over the weekend, President Lee Jae Myung called for a thorough investigation into the attacks.
On Thursday, Shinhan Bank said personal information of around 25,000 customers, including their names, phone numbers and annual income, had been leaked. Sources said the bank was attacked by hackers who utilized advanced AI tools.
Personal information of 89 customers was found to have been leaked from Hana Bank, while Woori Bank and NH Nonghyup Bank were also targeted in similar hacking attempts, though no personal information was leaked as the banks blocked unauthorized access to their systems.
