This detection rule identifies instances where a systemd service is started by an unusual parent process on Linux systems. Systemd services, managed through the systemctl binary, are a common attack vector for persistence mechanisms employed by malicious actors. By monitoring attempts to start, enable, or reenable systemd services, this rule can help detect unauthorized activities that may indicate a compromise. The rule utilizes multiple Osquery queries to further investigate the context of the service execution, gathering file information, user account details, running processes, and open sockets to provide a comprehensive view of the potential incident. The detection logic is focused on filtering out benign executions associated with known parent processes while flagging atypical behaviors that could suggest malicious intent.
