Mirae Asset Securities Co. disclosed on Saturday that it experienced cyberattacks leading to the exposure of customer and employee data. Unauthorized external access occurred on Wednesday and Thursday, targeting its mobile web phone authentication login service and internal system. As a result, personal information of approximately 3,800 customers and details of over 35,000 current, former employees, and contractors were leaked.

The compromised data included customer account numbers and personal information such as names, employee ID numbers, email addresses, mobile phone numbers, and passwords. Mirae Asset promptly blocked the affected access routes upon detecting suspicious activity from external IP addresses and activated its emergency response system.

The company reported the incident to the Financial Services Commission, the Financial Supervisory Service, and the Personal Information Protection Commission.
