On October 2, Hana Bank announced, "It has been determined that the information of 89 individuals—including resident registration numbers, names, addresses, email addresses, telephone numbers, mobile phone numbers, and workplace names—was leaked through external hacking groups."

Hana Bank explained that this leak occurred during an unauthorized access attempt by external hackers to the bank's Operational Data System (ODS).

The bank stated, "This incident resulted from abnormal access attempts by external hacking agents targeting our Operational Data System (ODS). This system operates independently from our internet and mobile banking transaction systems and, as such, is not related to the leakage of customers' financial transaction information." Hana Bank is individually notifying affected customers and plans to fully compensate for any damages resulting from the leak, in accordance with relevant regulations if such damages are confirmed.

The bank added, "We take this incident extremely seriously and will do our utmost to thoroughly investigate the root cause and implement measures to prevent recurrence in close cooperation with relevant authorities. We deeply apologize for any concern this may have caused to our valued customers."

Recently, there has been a series of customer information leaks in the banking sector. The previous day, Shinhan Bank announced that its telecommunications protocol structure (code) had been unlawfully hacked, resulting in the leakage of information on approximately 25,000 customers. On the same day, KB Kookmin Bank also disclosed that information belonging to 119 customers had been leaked externally.

On this day, the Financial Services Commission convened an emergency contingency meeting chaired by Secretary General Shin Jinchang to review recent cases of information leaks and the associated attack types and techniques targeting financial firms. In addition, banks and card companies were instructed to conduct their own security inspections.
