Threat Risk: Medium
Victim: Gmarket (E-commerce platform)
Incident: Unauthorized access to an external API resulting in a personal information leak.
Impact: Exposure of customer PII and unauthorized use of e-coupon PINs.
Attacker: Unidentified threat actors
Analysis: The breach occurred via unauthorized access to an external service API, allowing attackers to scrape PII and e-coupon PINs. While passwords remained secure, the compromise of contact information and voucher codes facilitated direct financial theft. This incident underscores the critical risk of insecure third-party API integrations.
Recommendations: Audit and secure all external-facing APIs for authorization and authentication flaws; Implement strict rate limiting and anomaly monitoring on API endpoints to detect scraping; Rotate and refresh sensitive identifiers, such as voucher PINs, immediately following a breach
