description: The following analytic identifies usage of `wmic.exe` spawning a local
or remote process, identified by the `node` switch. During triage, review parallel
processes for additional commands executed. Look for any file modifications before
and after `wmic.exe` execution. In addition, identify the remote endpoint and confirm
execution or file modifications. Contain and isolate the endpoint as needed.
data_source:
- Sysmon Event ID 1
search:
selection1:
OriginalFileName: wmic.exe
selection2:
Image|endswith: wmic.exe
selection3:
CommandLine: '*node*'
condition: (selection1 or selection2) and selection3
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. Deprecated because duplicate of Remote Process Instantiation via
WMI.
known_false_positives: Administrators may use this legitimately to gather info from
remote systems. Filter as needed.
