protothema.gr Domain Breach Exposure Report

The telemetry indicates a significant exposure of 379 historical data breaches and 47 active infostealer logs associated with protothema.gr. The majority of these events, 89%, are historical data breaches, while 11% are active infostealer logs. The timeline shows a notable increase in employee and client-related events from September 2025 onwards, peaking in March and April 2026. Malware families identified include Redline (34%) and LummaC2 (8.5%). The data originates primarily from combolist sources (95.8%) and database dumps (4.2%), with targeted services including the main domain and its login pages. Geographically, the United States accounts for the largest portion of the observed activity (0%). This exposure presents a high risk due to the large volume of historical data breaches and ongoing infostealer activity, potentially impacting a substantial number of employees and clients. The prevalence of Redline and LummaC2 suggests a focus on credential harvesting. Prioritization should be given to incident response for active infostealer threats, comprehensive credential hygiene for affected employees and clients, and a thorough review of data security practices to prevent future data breaches. The lack of a specified industry sector requires further investigation to tailor remediation efforts.
