Toss Bank Also Targeted by Hacking Attempts Using Same IP as Shinhan Bank Attacker

It has been confirmed through SBS reporting that the internet protocol (IP) address used by attackers in recent hacking incidents targeting banks and financial institutions also attempted to access Toss Bank servers.

According to data submitted by Toss Bank to Representative Kim Hyung-yeon of the Rebuilding Korea Party, a member of the National Assembly's Political Affairs Committee, on October 5, some of the IP addresses that recently hacked Shinhan Bank were found to have attempted access to Toss Bank servers since early this year.

Previously, after hacking damage occurred at seven financial companies including Shinhan, KB Kookmin, Hana, and BNK Busan Bank, as well as Yegaram Savings Bank, Welcome Savings Bank, and Hyundai Capital, regulatory authorities shared the IPs used in the attacks with the financial sector and ordered inspections. Now, hacking attempts targeting an internet-only bank have also been confirmed.

According to the data, two U.S. IP addresses that attacked Shinhan Bank attempted to access Toss Bank servers three times in January of this year and 11 times between July and August.

However, because Toss Bank blocked the connection attempts, no security breaches or customer personal information leaks occurred.

As the recent hacking attacks appear to have been attempted much earlier than initially known, experts point out that a comprehensive inspection across the entire financial sector is necessary.

Financial authorities have instructed banks and card companies to complete emergency inspections by October 6, and securities firms, insurance companies, and savings banks to finish by October 8.
