The following analytic assists with identifying a PowerShell process spawned as a child or grand child process of commonly abused processes during lateral movement techniques including services.exe, wmiprsve.exe, svchost.exe, wsmprovhost.exe and mmc.exe. Legitimate Windows features such as the Service Control Manager, Windows Management Instrumentation, Task Scheduler, Windows Remote Management and the DCOM protocol can be abused to start a process on a remote endpoint. Looking for PowerShell spawned out of this processes may reveal a lateral movement attack. Red Teams and adversaries alike may abuse these services during a breach for lateral movement and remote code execution.
