The following analytic identifies WmiPrvSE.exe spawning a process. This typically occurs when a process is instantiated from a local or remote process using wmic.exe. During triage, review parallel processes for suspicious behavior or commands executed. Review the process and command-line spawning from wmiprvse.exe. Contain and remediate the endpoint as necessary.

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.

Required field

  • _time
  • Processes.process
  • Processes.parent_process_name
  • Processes.user
  • Processes.dest
  • Processes.process_name

Kill Chain Phase

  • Actions on Objectives

Known False Positives

Although unlikely, administrators may use wmi to execute commands for legitimate purposes.


Risk Score Impact Confidence Message
49.0 70 70 A remote instance execution of wmic.exe that will spawn $parent_process_name$ in host $dest$
