Remote Process Instantiation via WMI

The following analytic detects the execution of wmic.exe with parameters to spawn a process on a remote system. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on command-line executions and process telemetry mapped to the `Processes` node of the `Endpoint` data model. This activity is significant as WMI can be abused for lateral movement and remote code execution, often used by adversaries and Red Teams. If confirmed malicious, this could allow attackers to execute arbitrary code on remote systems, facilitating further compromise and lateral spread within the network.
