Threat Risk: Medium
Victim: E-commerce fashion platform
Incident: Unauthorized access to an order-inquiry API resulted in a data breach of 160,000 customer records.
Impact: Exposure of names, emails, phone numbers, and shipping addresses for approximately 21,000 users.
Attacker: Unidentified threat actors
Analysis: Threat actors exploited an insecure API endpoint to scrape customer data, bypassing intended access controls. While financial credentials remained secure, the exposure of shipping and contact details significantly increases the risk of targeted smishing and phishing campaigns.
