Mirae Asset says data breaches exposed customer, employee information

SEOUL, Nov. 7 - Mirae Asset Securities Co. announced on Saturday that it had fallen victim to cyberattacks, resulting in the exposure of sensitive customer and employee data. The breaches, which took place on Wednesday and Thursday, targeted the company's mobile web phone authentication login service and internal system. Consequently, unauthorized external access granted access to the personal information of approximately 3,800 customers and the details of over 35,000 current, former, and contractor employees.

The leaked information included customer account numbers, names, employee ID numbers, email addresses, mobile phone numbers, and passwords for corporate data. Mirae Asset swiftly implemented measures, blocking the compromised access routes and activating its emergency response system following detection of suspicious activity from external IP addresses.

The company also promptly reported the incident to relevant regulatory bodies, including the Financial Services Commission, the Financial Supervisory Service, and the Personal Information Protection Commission.
