This rule detects the loading of the 'Microsoft.ActiveDirectory.Management.dll' DLL via PowerShell's 'Import-Module' or its alias 'ipmo'. This DLL is part of the Active Directory module for PowerShell and is frequently used by attackers to perform Active Directory enumeration, especially in environments where RSAT tools are not installed or administrative privileges are not readily available. The detection focuses on the command line payload containing both the module import command and the specific DLL name.
