eli5: Many a times, attackers leverage native Windows utilities that are designed
|
|
to help administrators better manage their systems, infrastructure, and auditing,
|
|
but are instead leveraged for malicious purposes. In this case, we are looking for
|
|
instances of wmic.exe being run with various parameters that are not typically used
|
|
by administrators.

|
how_to_implement: You must be ingesting data that records process activity from your
|
|
hosts to populate the Endpoint data model in the Processes node. You must also be
|
|
ingesting logs with both the process name and command line from your endpoints.
|
|
The command-line arguments are mapped to the "process" field in the Endpoint data
|
|
model.
