realtor.ca Domain Breach Exposure Report

The domain realtor.ca has experienced a significant number of events, with 8,554 out of 8,806 total events attributed to historical data breaches and active infostealer logs. The majority of these events, 7,499, are classified as historical data breaches originating from "Combolist sources," indicating a large-scale compromise of credential data. Additionally, 1,307 events are linked to active infostealer logs, with LummaC2, Acreed, and Rhadamanthys being the most prevalent malware families observed. The timeline shows a notable increase in client-related events from February 2026 onwards, coinciding with a rise in employee-related events in March 2026, suggesting a potential escalation of compromise activity impacting both user and internal accounts. This exposure presents a high-risk scenario due to the sheer volume of historical data breaches and the active presence of infostealer malware. The prevalence of credential stuffing attacks is likely high, given the "Combolist sources" classification. The increasing trend in client and employee events from early 2026 warrants immediate attention. Remediation efforts should focus on comprehensive credential hygiene, including mandatory password resets for all users, enhanced multi-factor authentication deployment, and thorough security audits of systems that handle client data. Investigating the specific infostealer infections and their impact is critical to understanding the extent of data exfiltration.
