+description: This search detects registry key license at host where Remcos RAT agent
+  is installed.
+search: '| tstats `security_content_summariesonly` count min(_time) as firstTime max(_time)
+  as lastTime values(Registry.registry_path) as  registry_path FROM datamodel=Endpoint.Registry
+  where (Registry.registry_key_name=*\\Software\\Remcos*) by Registry.dest  Registry.user
+  Registry.registry_key_name Registry.process_id| `drop_dm_object_name(Registry)`
+  | `security_content_ctime(lastTime)` | `security_content_ctime(firstTime)`|`remcos_client_registry_install_entry_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 `Registry` node. Also make sure
+  that this registry was included in your config files ex. sysmon config to be monitored.
