Remote Process Instantiation via WinRM and PowerShell

The following analytic detects the execution of `powershell.exe` with arguments used to start a process on a remote endpoint via the WinRM protocol, specifically targeting the `Invoke-Command` cmdlet. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on command-line executions and process telemetry. This activity is significant as it may indicate lateral movement or remote code execution attempts by adversaries. If confirmed malicious, this could allow attackers to execute arbitrary code on remote systems, potentially leading to further compromise and lateral spread within the network.
