What it detects

This rule identifies process executions of IMEWDBLD.exe where the command line contains an http:// or https:// URL, indicating an attempt to download an arbitrary file. Such behavior is relevant because attackers can use built-in binaries to fetch and stage payloads while blending into normal process activity. Telemetry required includes Windows process creation fields that provide the executable path/name and the full command line.
