description: This analytic identifies Get-DomainTrust from PowerView in order to gather
|
|
domain trust information. Typically, this is utilized within a script being executed
|
|
and used to enumerate the domain trust information. This grants the adversary an
|
|
understanding of how large or small the domain is. During triage, review parallel
|
|
processes using an EDR product or 4688 events. It will be important to understand
|
|
the timeline of events around this activity.

search:
|
|
selection1:
|
|
CommandLine: '*get-domaintrust*'
|
|
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. In addition,
|
|
confirm the latest CIM App 4.20 or higher is installed and the latest TA for the
|
|
endpoint product.
|
|
known_false_positives: Limited false positives as this requires an active Administrator
|
|
or adversary to bring in, import, and execute.
