Following Mirae Asset Global Investment Management and Daishin Securities, a hacking incident has also occurred at Hanwha Securities.
On the 3rd, Hanwha Securities announced that it had confirmed on the 29th of last month that some information was leaked due to unauthorized access to an external groupware solution in use. Recently, government data leak incidents caused by hacking have been spreading across the entire financial sector.
According to Hanwha Securities, the leaked data identified so far includes 15 cases of customer information, 2 cases of employee-related information, and 14 cases of general personal information. The specific items of leaked personal information vary by case. Hanwha Securities confirmed that these include names, account numbers, contact details, addresses, dates of birth, email addresses, resident registration numbers, and driver’s license numbers. Among these, three cases were found to contain resident registration numbers.
Upon recognizing the incident, Hanwha Securities immediately blocked external access and completed an emergency security patch in collaboration with the solution provider. It is currently proceeding with reporting procedures to relevant institutional investors while investigating the exact scope and circumstances of the leak. The company is also providing individual notifications to affected customers.
A Hanwha Securities official said, “We are taking this matter very seriously and sincerely apologize for the concern caused to our customers,” adding, “We will thoroughly review our security management system going forward and make every effort to prevent recurrence.”
