Remote Process Instantiation via DCOM and PowerShell Script Block

This analytic detects PowerShell commands that initiate a process on a remote endpoint using the Distributed Component Object Model (DCOM) protocol. It specifically looks for the use of "ShellExecute" or "ExecuteShellCommand" within PowerShell Script Block Logging (EventCode=4104). This activity is significant as it may indicate lateral movement or remote code execution attempts by adversaries, potentially leading to further compromise and persistence within the network.
