What it detects

This rule flags Linux process creation where SAP NetWeaver runs a command-line interpreter, scripting/runtime, or common network/file-transfer utilities from within specific SAP servlet JSP work/root directories. Such parent-child process relationships can indicate webshell activity or post-exploitation command execution occurring from application context. It relies on process telemetry including ParentImage, CurrentDirectory, and the executed Image path suffix (e.g., /bash, /python3, /curl, /wget, /nc, /nmap).
