description: The following analytic identifies the common command-line argument used
|
|
by AzureHound `Invoke-AzureHound`. Being the script is FOSS, function names may
|
|
be modified, but these changes are dependent upon the operator. In most instances
|
|
the defaults are used. This analytic works to identify the common command-line attributes
|
|
used. It does not cover the entirety of every argument in order to avoid false positives.

data_source:
|
|
- Sysmon Event ID 1
|
|
search:
|
|
selection1:
|
|
CommandLine: '*invoke-azurehound*'
|
|
condition: selection1
|
|
how_to_implement: To successfully implement this search you need to be ingesting information
|
|
on process that include the name of the process responsible for the changes from
|
|
your endpoints into the `Endpoint` datamodel in the `Processes` node.
|
|
known_false_positives: Unknown.
