+description: The following hunting analytic assists with identifying the proces execution of commonly used utilities from NirSoft. Potentially not adversary behavior, but worth identifying to know if the software is present and being used.
+search: '| tstats `security_content_summariesonly` count min(_time) as firstTime max(_time) as lastTime FROM datamodel=Endpoint.Processes by Processes.dest Processes.user Processes.parent_process Processes.process_name Processes.process Processes.original_file_name Processes.process_path Processes.process_id Processes.parent_process_id
+  | `drop_dm_object_name("Processes")` 
+  | `security_content_ctime(firstTime)`
+  | `security_content_ctime(lastTime)`
+  | `is_nirsoft_software`
+  | `windows_nirsoft_utilities_filter`'
+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.
+known_false_positives: False positives may be present. Filtering may be required before setting to alert.
