#### Description

The following analytic identifies usage of `wmic.exe` spawning a local or remote process, identified by the `node` switch. During triage, review parallel processes for additional commands executed. Look for any file modifications before and after `wmic.exe` execution. In addition, identify the remote endpoint and confirm execution or file modifications. Contain and isolate the endpoint as needed.

#### Search

```

| tstats `security_content_summariesonly` count min(_time) as firstTime max(_time) as lastTime from datamodel=Endpoint.Processes where `process_wmic` Processes.process=*node* by Processes.dest Processes.user Processes.parent_process Processes.process_name Processes.process Processes.process_id Processes.parent_process_id 
| `drop_dm_object_name(Processes)` 
| `security_content_ctime(firstTime)` 
| `security_content_ctime(lastTime)` 
| `remote_wmi_command_attempt_filter`
```

#### Macros
The SPL above uses the following Macros:
* [process_wmic](https://github.com/splunk/security_content/blob/develop/macros/process_wmic.yml)
* [security_content_ctime](https://github.com/splunk/security_content/blob/develop/macros/security_content_ctime.yml)
* [security_content_summariesonly](https://github.com/splunk/security_content/blob/develop/macros/security_content_summariesonly.yml)

Note that `remote_wmi_command_attempt_filter` is a empty macro by default. It allows the user to filter out any results (false positives) without editing the SPL.

#### Required field
* _time
* Processes.user
* Processes.process_name
* Processes.parent_process_name
* Processes.dest
* Processes.parent_process
* Processes.parent_process_id
* Processes.process_id


#### 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. Deprecated because duplicate of Remote Process Instantiation via WMI.

#### Known False Positives
Administrators may use this legitimately to gather info from remote systems. Filter as needed.

#### RBA

| Risk Score  | Impact      | Confidence   | Message      |
| ----------- | ----------- |--------------|--------------|
| 36.0 | 60 | 60 | A wmic.exe process $process$ contain node commandline $process$ in host $dest$ |


Note that risk score is calculated base on the following formula: `(Impact * Confidence)/100`
