(LEAD) 89 customers' personal information leaked from Hana Bank

89 customers' personal information has been compromised following a hacking attack on Hana Bank, the lender announced on Friday. The leaked data included residents' registration numbers, names, addresses, and phone numbers, as disclosed by Hana Bank. The breach occurred after an external hacker infiltrated the bank's outdoor sales system, the bank informed.

In response, Hana Bank extended an apology to affected customers and pledged to take all necessary measures to prevent similar occurrences in the future. Industry reports suggest that Woori Bank and NH Nonghyup Bank also faced hacking attempts, but were successful in safeguarding customer data by preventing unauthorized access. Earlier, industry insiders disclosed a data breach at KB Kookmin Bank, a leading commercial bank, where over 100 customer records were reportedly stolen through a hacking incident.

This incident was attributed to a similar attack orchestrated by Shinhan Bank, which subsequently revealed that personal details of approximately 25,000 customers, including income, names, and phone numbers, were exposed.
