UNC3944 | VMware - AD Group Membership Change via WinRM
Detects the addition of a member to a sensitive Active Directory group related to VMware administration (e.g., 'vSphere Admins', 'ESX Admins') using net.exe executed via WinRM (wsmprovhost.exe). This behavior is a key TTP used by threat groups like UNC3944 to escalate privileges and gain control over the vSphere environment after an initial compromise.
