gotowebinar.com Domain Breach Exposure Report

The telemetry indicates a significant exposure related to the gotowebinar.com domain, with a high volume of historical data breaches (775 events) and active infostealer logs (162 events) observed over the reporting period. The majority of these events are linked to combolist sources (97.9%), suggesting credential stuffing or account takeover attempts. Malware families such as Redline, LummaC2, and Rhadamanthys are frequently associated with these infostealer logs. The timeline shows a notable increase in both employee and client-related events starting in early 2026, particularly in March and April, with a concentration of affected users in India and the United States. Given the high number of data breaches and the prevalence of infostealer activity, this exposure poses a critical risk to the organization and its users. The focus should be on immediate credential hygiene, including mandatory password resets for all users, enhanced monitoring for suspicious login activity, and a review of access controls for the gotowebinar.com service. Further investigation into the root cause of the data breaches and the specific infostealer campaigns is recommended to prevent future compromise.
