Windows Management Instrumentation
Adversaries may abuse Windows Management Instrumentation (WMI) to achieve execution. WMI is a Windows administration feature that provides a uniform environment for local and remote access to Windows system components. It relies on the WMI service for local and remote access and the server message block (SMB)  and Remote Procedure Call Service (RPCS)  for remote access. RPCS operates over port 135. 
An adversary can use WMI to interact with local and remote systems and use it as a means to perform many tactic functions, such as gathering information for Discovery and remote Execution of files as part of Lateral Movement.  
The DustySky dropper uses Windows Management Instrumentation to extract information about the operating system and whether an anti-virus is active.
|Privileged Account Management||
Prevent credential overlap across systems of administrator and privileged accounts. 
|User Account Management||
By default, only administrators are allowed to connect remotely using WMI. Restrict other users who are allowed to connect, or disallow all users to connect remotely to WMI.
Monitor network traffic for WMI connections; the use of WMI in environments that do not typically use WMI may be suspect. Perform process monitoring to capture command-line arguments of "wmic" and detect commands that are used to perform remote behavior.
