How To Implement

You must be ingesting data that records process activity from your hosts to populate the Endpoint data model in the Processes node. You should run the baseline search Previously Seen Zoom Child Processes - Initial to build the initial table of child processes and hostnames for this search to work. You should also schedule at the same interval as this search the second baseline search Previously Seen Zoom Child Processes - Update to keep this table up to date and to age out old child processes. Please update the previously_seen_zoom_child_processes_window macro to adjust the time window.

Required field

  • _time
  • Processes.parent_process_name
  • Processes.parent_process_id
  • Processes.process_name
  • Processes.process
  • Processes.parent_process_name
  • Processes.process_id
  • Processes.dest

Kill Chain Phase

  • Actions on Objectives

Known False Positives

A new child process of zoom isn't malicious by that fact alone. Further investigation of the actions of the child process is needed to verify any malicious behavior is taken.


Risk Score Impact Confidence Message
