description: Monitor for signs that Ntdsutil, Vssadmin, or Wmic has been used to create
|
|
a shadow copy.
|
|
how_to_implement: You must be ingesting endpoint data that tracks process activity,
|
|
including parent-child relationships from your endpoints, to populate the Endpoint
|
|
data model in the Processes node. The command-line arguments are mapped to the "process"
|
|
field in the Endpoint data model.
