Try in Splunk Security Cloud


This analytic is to detect a suspicious wmic commandlined that uninstall application non interactively. This technique was seen in IceID to uninstall av products to the compromised host to bypassed and evade detections. This Hunting query maybe a good indicator that some process tries to uninstall application using wmic which is not a common behavior. This approach may seen in some script or third part appication to uninstall their application but it is a good thing to check what it uninstall and why.

How To Implement

To successfully implement this search, you need to be ingesting logs with the process name, parent process, and command-line executions from your endpoints. If you are using Sysmon, you must have at least version 6.0.4 of the Sysmon TA.

Required field

  • _time
  • Processes.dest
  • Processes.user
  • Processes.parent_process_name
  • Processes.parent_process
  • Processes.original_file_name
  • Processes.process_name
  • Processes.process
  • Processes.process_id
  • Processes.parent_process_path
  • Processes.process_path
  • Processes.parent_process_id
