Hacking incident IP of major financial companies also attempted to access Kakao Bank, K Bank, and Toss Bank servers

(Seoul = Yonhap News) Reporter Lee Do-heun = It was found that the attacker's Internet address (IP) used in the recent hacking incident at a major financial company also attempted to access the servers of Kakao Bank [323410] and K Bank [279570].

According to the financial sector on the 6th, some of the IPs that recently hacked commercial banks also attempted to access Kakao Bank and K Bank servers this year.

After hacking damage occurred at Shinhan, KB Kookmin, Hana, BNK Busan Bank, Yegaram, Welcome Savings Bank, and Hyundai Capital, financial authorities shared the IP used in the attack with the financial sector and ordered an inspection. As a result of the inspection, attempts to access internet-only banks were also confirmed.

It was revealed that the IP in question had accessed Kakao Bank several times since January of this year. However, it is known that the attempt was detected and blocked through the security system, and there have been no cases of additional attacks or damage to date.

An attempt to connect to K Bank using the same IP was confirmed, but it also appeared that there was no damage caused by the connection attempt.

It is also known that the IP in question attempted to access the Toss Bank server a total of 10 times from January to August of this year. However, as Toss Bank blocked the access attempt, no infringement damage such as leakage of customer personal information occurred.

An official from the financial sector explained, “An attacker usually attempts to access an unspecified number of institutions to check whether they are vulnerable, and then proceeds with additional attacks if the vulnerability is not confirmed or blocked.”
