onclickads.net Domain Breach Exposure Report

The domain onclickads.net has been associated with 114 client-related events over the past year, predominantly comprising 103 historical data breaches and 11 active infostealer logs. The data breaches are primarily linked to "Combolist sources," indicating a high likelihood of credential stuffing attacks or the exposure of previously compromised credentials. Infostealer activity is attributed to malware families such as Redline, Rhadamanthys, and LummaC2, which are known for exfiltrating sensitive information like login credentials and financial data. The majority of affected systems are running Windows 10. The observed activity peaked in March 2026, with a significant number of client events recorded. This exposure presents a moderate risk, primarily affecting clients and potentially leading to account takeovers and further downstream compromises. The prevalence of infostealer malware targeting Windows systems suggests a focus on harvesting credentials. Remediation efforts should prioritize investigating the source of the "Combolist sources" data breaches, enhancing client-side security controls to detect and prevent infostealer infections, and monitoring for any further suspicious activity originating from or targeting onclickads.net.
