description: 'The following hunting analytic identifies the use of `wmic.exe` enumerating
  local groups on the endpoint. \

  Typically, by itself, is not malicious but may raise suspicion based on time of
  day, endpoint and username. \

  During triage, review parallel processes and identify any further suspicious behavior.'
data_source:
- Sysmon Event ID 1
search:
  selection1:
    CommandLine: '*group get name*'
    Image|endswith: wmic.exe
  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.
