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.'

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.
