"Comprehensive Review of Personal Information Protection Framework and Security Systems"

OK Savings Bank said on October 15 that it had confirmed a recent hacking attack exposed the personal information of 250 customers.

According to OK Savings Bank, a detailed investigation with two external security monitoring companies confirmed that the data breach affected 250 customers who had used the loan application service on its website.

The exposed information included names, dates of birth, mobile phone numbers, account numbers, addresses, email addresses, employers' names, business registration numbers, annual incomes, and loan amounts, as well as other loan application-related information.

On October 12, OK Savings Bank detected signs of unauthorized access to the loan application webpage by an internet protocol (IP) address suspected of being involved in a hacking attack and immediately shut down the related system.

It subsequently reported the incident to relevant authorities, including the Financial Supervisory Service, in accordance with applicable regulations. The bank blocked the suspected IP address used by the hacker and the access route, and strengthened emergency security checks and monitoring across its systems.

OK Savings Bank said that no further signs of anomalies or suspicious activity have been detected so far.

An OK Savings Bank official said, "We take this data breach very seriously and deeply apologize for causing concern to our customers. We will use this incident as an opportunity to thoroughly review our personal information protection framework and security systems, and make every effort to strengthen our security systems to prevent a recurrence."
