description: This analytic looks for the execution of `wmic.exe` with command-line
|
|
arguments utilized to discover remote systems. The arguments utilized in this command
|
|
return a list of all the systems registered in the domain. Red Teams and adversaries
|
|
alike may leverage WMI and wmic.exe to identify remote systems for situational awareness
|
|
and Active Directory Discovery.
