Possible Lateral Movement PowerShell Spawn

The following analytic detects the spawning of a PowerShell process as a child or grandchild of commonly abused processes like services.exe, wmiprvse.exe, svchost.exe, wsmprovhost.exe, and mmc.exe. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on process and parent process names, as well as command-line executions. This activity is significant as it could indicates lateral movement or remote code execution attempts by adversaries. If confirmed malicious, this behavior could allow attackers to execute code remotely, escalate privileges, or persist within the environment.
