Gmarket has completed compensation for customers affected by a personal data breach that occurred late last month.
The incident was caused by unauthorized access exploiting an API vulnerability in an external service.
Customer names, IDs, e-coupon PIN numbers, phone numbers, email addresses, and home addresses were leaked, but login passwords were not compromised.
The scale of the affected customer base was not disclosed.
The breach came to light after circumstances were discovered indicating that third parties had unauthorizedly used e-coupon products purchased by customers.
Gmarket fully compensated customers who suffered financial losses with the face value of their e-coupons, and also provided 10,000 won in Smile Cash to customers whose personal information was leaked even if they had no e-coupon damages.
The company is also sequentially replacing the e-coupon PIN numbers for all customers holding gift certificates.
