description: This analytic is to look for wmi commandlines to execute or create process.
|
|
This technique was used by adversaries or threat actor to execute their malicious
|
|
payload in local or remote host. This hunting query is a good pivot to start to
|
|
look further which process trigger the wmi or what process it execute locally or
|
|
remotely.

how_to_implement: To successfully implement this search, you need to be ingesting
|
|
logs with the process name, parent process, and command-line executions from your
|
|
endpoints. If you are using Sysmon, you must have at least version 6.0.4 of the
|
|
Sysmon TA.
