(Seoul = Yonhap News) Reporters Han Ji-hoon, Bae Young-kyung, Park Soo-hyun, and Kang Soo-ryun = Following Shinhan Bank, an incident in which customer information was leaked due to hacking occurred at KB Kookmin Bank.

According to financial authorities and the financial sector on the 2nd, KB Kookmin Bank recently confirmed that about 100 pieces of customer information were leaked due to an external intrusion.

It is reported that the bank blocked the server and access path immediately after becoming aware of the possibility that information was leaked through abnormal external access.
