Risk Score

High Risk

Massive event volume or critical assets compromised.

AI Findings Summary

Critical

The domain tdsynnex.com exhibits a high-risk score of 94, primarily driven by a significant volume of historical data breaches (77.6%) and active infostealer logs (22.4%) over the reporting period. A total of 3,752 events were observed, impacting 965 employees and 2,787 clients. The data indicates a substantial increase in client-related events during March 2026, coinciding with a surge in employee-related events in January and April 2026. Malware families such as LummaC2, Acreed, and Rhadamanthys are prevalent, suggesting ongoing compromise and data exfiltration activities. The presence of "Combolist sources" (81.5%) and "Database dumps" (18.5%) in leak repositories points to credential stuffing and data leakage risks. Given the high volume of data breaches and active infostealer activity, this exposure poses a critical risk. The prevalence of infostealer malware targeting credentials, coupled with the large number of affected clients and employees, indicates a strong potential for widespread account compromise and further data exfiltration. Remediation efforts should focus on immediate credential resets for all affected employees and clients, enhanced monitoring of authentication systems, particularly those related to SSO services like sso-emea.tdsynnex.com and ion.tdsynnex.com, and a thorough investigation into the root cause of the data breaches and infostealer infections.
