echo.msk.ru Domain Breach Exposure Report

The domain echo.msk.ru has experienced a significant number of data breach events (961) and active infostealer logs (183) over the reporting period. The majority of these events are attributed to historical data breaches, with a notable portion also linked to active infostealer activity. The timeline indicates a surge in client-related events, particularly in March 2026, and a consistent presence of employee-related events throughout the latter half of 2025 and into 2026. Malware families such as Redline and Vidar are prominent in the infostealer logs, suggesting common credential harvesting techniques. The data breaches are predominantly linked to "Combolist sources," indicating compromised credentials being aggregated and sold. The high volume of data breaches and infostealer activity poses a substantial risk to the organization and its users. The prevalence of "Combolist sources" suggests that credentials exposed in past breaches are being actively exploited. The targeted services include the main domain and specific pages like "my.html" and "session.html," indicating potential attempts to access user accounts or session information. The geographical breakdown shows activity originating from Canada and the United States, among other countries. Remediation efforts should focus on credential hygiene, including mandatory password resets, multi-factor authentication implementation, and enhanced monitoring for suspicious login activity, particularly for employee and client accounts.
