jkforum.net Domain Breach Exposure Report

The domain jkforum.net has experienced a significant number of events, with over 50,000 total occurrences recorded between July 2025 and June 2026. The vast majority of these events, approximately 88.8%, are classified as historical data breaches, totaling 44,683 incidents. Additionally, there are 5,617 active infostealer logs, representing 11.2% of the total events. The data indicates a substantial exposure of client information, with 50,226 client-related events, and a smaller number of employee-related events at 74. The timeline shows a surge in client-related events from late 2025 into early 2026, with a notable increase in employee-related events in March and April 2026. The primary risk stems from the high volume of historical data breaches and active infostealer logs, suggesting a persistent compromise or widespread credential stuffing attacks targeting the domain. The prevalence of "Combolist sources" in leak repositories further supports this, indicating that credentials associated with jkforum.net are likely available on the dark web. The most common malware families observed are Redline, LummaC2, and Rhadamanthys, all known for their credential-stealing capabilities. Remediation efforts should focus on immediate credential reset for all users, enhanced monitoring for suspicious login activity, and a thorough security audit of the jkforum.net platform, particularly its member authentication and data handling processes.
