What it detects

This rule flags Windows process creation events whose command line contains both the service registry path and the string for NetworkProvider, indicating an attempt to add a new network provider via CLI. Attackers may use network provider changes to capture or expose credentials in clear text, aligning with credential-access objectives. It relies on process creation telemetry, specifically the command line content associated with the spawned process.
