What it detects

This rule identifies network connections where the initiating process is IMEWDBLD.EXE on Windows. Network activity from this binary can indicate misuse of the utility for command-and-control or staging additional payloads. It relies on telemetry that records network_connection events with the initiating process image path and whether the connection was initiated.
