ADTrapper is a security analysis platform tailored for cybersecurity experts focusing on Windows Active Directory (AD) authentication logs. It offers over 54 detection rules targeting various threats, including brute force attacks, password spraying, and privilege escalation. The platform enables users to analyze logs without needing authentication, allowing for immediate action. It supports interactive visualizations, which help users understand network relationships through force-directed graphs. Setting up ADTrapper is streamlined with Docker. A single command can deploy the entire application, and users can easily upload authentication logs using a provided PowerShell script. This script allows for different levels of log collection, ranging from basic to extensive analyses that incorporate Active Directory context. Notably, the tool also integrates with SharpHound data, enhancing its analytical capabilities. The logging functionality covers crucial authentication events, such as logon successes and failures, Kerberos authentication, and account lockouts. For more advanced users, the system can collect specific AD Certificate Services events, essential for detecting potential attacks on certificate infrastructure. The deployment options cater to various environments, including cloud services like AWS and Google Cloud, ensuring flexibility for different organizational needs. For ongoing management, the platform includes commands for viewing service statuses, logs, and backing up data. It encourages community contributions through its GitHub repository, where users can fork the project and submit enhancements. The infrastructure is built using modern technologies like Next.js and Node.js, ensuring a robust and efficient application for security professionals.
