In a hacking incident involving Saemaul Geumgo, personal information of approximately 400 customers has been compromised, with the originating IP addresses tentatively traced to China, Thailand, and South Korea. Financial authorities are investigating a potential link between this incident and recent hacking attacks utilizing AI agents, although no direct connection has been confirmed so far.
According to Yonhap News Agency on October 13, the breach at Saemaul Geumgo involved the exposure of names, addresses, and encrypted resident registration numbers among other personal data. The hacking attack occurred during the holiday period on October 10, and the incident was reported to financial authorities on the same day.
The leaked information varies by customer but is believed to include customer numbers, names, encrypted resident registration numbers, account numbers, birth dates, mobile phone numbers, addresses, email addresses, and account balances.
Previously, Saemaul Geumgo had blocked abnormal access from overseas IPs to prevent data leaks. However, subsequent attacks using dozens of new IP addresses ultimately led to the actual data breach.
The IP addresses involved in the attack have been tentatively identified as originating from China, Thailand, and South Korea. Financial authorities are examining the relationship between this incident and the recent spate of hacking attacks involving AI agents, but as of now, no correlation has been established.
Meanwhile, OK Savings Bank has also reported a hacking attempt. The bank detected unauthorized access attempts on one of its web pages on October 12 and immediately blocked the information retrieval system, notifying relevant authorities of a potential data leak. It is currently being verified whether any personal data was actually compromised.
OK Savings Bank stated, "No additional unusual signs or suspicious situations have been reported," and is investigating the actual data leak and the precise circumstances of the incident in collaboration with external security experts.
