Threat Risk: Medium
Victim: 29CM (Musinsa subsidiary)
Incident: Unauthorized external access to a customer order API.
Impact: Personal information of 159,000 customers was exposed, with 20,000 experiencing high-sensitivity data leaks.
Attacker: Unidentified threat actors
Analysis: The breach was caused by unauthorized external access to an API used for retrieving order information. While payment data and passwords remained secure, the leak of names, addresses, and phone numbers for 20,000 users significantly increases the risk of targeted phishing. This incident underscores the persistent danger of unsecured or poorly monitored API endpoints.
Recommendations: Enforce strict authentication and authorization checks for all API endpoints.; Implement anomaly detection to identify and block abnormal external access patterns in real-time.; Advise users to be vigilant against social engineering attempts following PII leaks.
