What it detects

This rule flags proxy traffic where the requested URI contains the path '/pwndrop/'. It targets access to web server endpoints associated with PwnDrp, which are commonly used to serve payloads or command-and-control artifacts. The detection relies on proxy telemetry that records the client-requested URI (c-uri).
