+description: 'The following detection identifies control.exe spawning from an office product. This detection identifies any Windows Office Product spawning `control.exe`.
+  In malicious instances, the command-line of `control.exe` will contain a file path to a .cpl or .inf, related to CVE-2021-40444. In this
+  instance, we narrow our detection down to the Office suite as a parent process.
+  During triage, review all file modifications. Capture and analyze any artifacts
+  on disk. review parallel and child processes to identify further suspicious behavior'
+search: '| tstats `security_content_summariesonly` count min(_time) as firstTime max(_time)
+  as lastTime from datamodel=Endpoint.Processes where Processes.parent_process_name
+  IN ("winword.exe","excel.exe","powerpnt.exe","mspub.exe","visio.exe") Processes.process_name=control.exe

+  | `security_content_ctime(firstTime)`| `security_content_ctime(lastTime)`| `office_spawning_control_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: Limited false positives should be present.
