parpacific.com Domain Breach Exposure Report

The telemetry indicates a significant exposure event affecting 753 historical data breaches, with 742 employee-related and 11 client-related incidents. The majority of the exposure, 86.3%, originates from database dumps, with an additional 13.7% from combolist sources. The timeline shows a substantial increase in employee-related incidents starting in January 2026, peaking in June 2026. Targeted services primarily include Microsoft-related OWA (Outlook Web App) endpoints, suggesting potential compromise of email or collaboration platforms. The high volume of historical data breaches and the concentration of exposure from database dumps indicate a critical risk of credential stuffing, account takeover, and further data exfiltration. Given the high risk score of 91 and the nature of the data breaches, immediate focus should be on credential reset for all affected employees and clients, enhanced monitoring of OWA endpoints for suspicious login activity, and a thorough review of database security practices. The prevalence of Microsoft OWA suggests that compromised credentials could lead to unauthorized access to sensitive internal communications and potentially client data.
