Threat Risk: Medium
Victim: Gmarket
Incident: Data breach caused by a third-party API vulnerability.
Impact: Exposure of customer PII and unauthorized redemption of e-coupons.
Attacker: Unidentified threat actors
Analysis: The breach stemmed from a vulnerability in a third-party API, allowing attackers to scrape sensitive customer information. While passwords remained secure, the exposure of PII and e-coupon PINs directly enabled financial theft. This highlights the persistent risk associated with third-party integrations and API security.
Recommendations: Audit and secure all external-facing API endpoints; Implement strict rate limiting and authentication for third-party service integrations; Rotate sensitive identifiers like coupon PINs following any suspected compromise
