mega.co.nz Domain Breach Exposure Report

The telemetry indicates a significant exposure event impacting 1073 clients and 199 employees, primarily driven by 1079 historical data breaches and 193 active infostealer logs. The data suggests a concentrated period of client exposure in March and April 2026, with employee exposure also peaking in March and April 2026. Malware families like LummaC2, Redline, and Acreed are prevalent, targeting the mega.co.nz domain and its login pages. The majority of exposed data originates from combolist sources, indicating credential stuffing or account takeover attempts. The primary affected geographies include the United States, France, Spain, New Zealand, and Italy. Given the high volume of historical data breaches and active infostealer activity targeting authentication endpoints, this situation presents a critical risk. The prevalence of infostealers and the targeting of login pages suggest a high likelihood of credential compromise, potentially leading to further unauthorized access and data exfiltration. Remediation efforts should focus on immediate credential rotation for all affected employees and clients, enhanced monitoring of mega.co.nz authentication endpoints for suspicious activity, and a thorough review of security controls to prevent future credential stuffing and infostealer infections.
