The Financial Supervisory Service (FSS) launched on-site inspections today (October 13) into Yegaram Savings Bank and Welcome Savings Bank following data leaks caused by hacking.
According to financial authorities and other sources, the FSS dispatched on-site inspection teams to the two savings banks today to investigate the causes of the recent hacking incidents and the circumstances surrounding the information leaks.
Yegaram Savings Bank estimates that approximately 50,000 cases of personal information—including customers' names, dates of birth, contact information, account numbers, resident registration numbers, employer names, and addresses—were leaked due to a hacking attack on September 30.
The exact scale of the leak is still being assessed.
Initially, in a notice posted on October 2, the bank listed only customers' names, dates of birth, and contact information as leaked items. It later updated the notice after learning that resident registration numbers, account numbers, and addresses had also been leaked.
Welcome Savings Bank suffered a data leak on September 27 due to a hacking attack, compromising corporate internet banking IDs, corporate names, representatives' names, company business contact numbers, mobile phone numbers, and email addresses.
The company estimated that out of a total of 2,370 leaked data items, 2,299 contained personal information.
The FSS plans to decide whether to convert the inspections into formal investigations depending on the progress of the on-site reviews.
Separately, the FSS has been conducting an on-site investigation since October 6 into Shinhan Bank, which has the largest scale of damage with the information leakage of approximately 25,000 customers.
At KB 국민은행 (KB Kookmin Bank), where the leak of 119 customers' information was uncovered while a regular audit was already underway, the IT inspection team on site has been deployed since October 1 to assess the situation.
The regular inspection is scheduled to run until the end of this month, with the possibility of an extension depending on the circumstances.
No separate inspection plans have been observed yet for Hana Bank, where the information of 89 customers was leaked, or for Hyundai Capital, where some personal information of 146 mortgage brokers was leaked.
Authorities appear to be conducting sequential inspections by prioritizing institutions with larger scales of damage.
Regarding BNK Busan Bank, where the information of 11 outsourced development employees was exposed, authorities view the necessity for an inspection as relatively low, considering the scale of the leak and the nature of the damage.
