What it detects

This rule identifies Windows process executions where the command line contains both "New-Service" and "-BinaryPathName" in PowerShell. Creating services from PowerShell can establish persistence or run attacker-controlled payloads with elevated or scheduled execution. The detection relies on process creation telemetry and inspects the full command line for these specific parameters.
