#### Description

Detect system information discovery techniques used by attackers to understand configurations of the system to further exploit it.

- **Type**: [TTP](https://github.com/splunk/security_content/wiki/Detection-Analytic-Types)
- **Product**: Splunk Enterprise, Splunk Enterprise Security, Splunk Cloud
- **Datamodel**: [Endpoint](https://docs.splunk.com/Documentation/CIM/latest/User/Endpoint)
- **Last Updated**: 2021-09-07
- **Author**: Patrick Bareiss, Splunk
- **ID**: 8e99f89e-ae58-4ebc-bf52-ae0b1a277e72

| ID             | Technique        |  Tactic             |

#### Search

```

| tstats `security_content_summariesonly` count min(_time) as firstTime max(_time) as lastTime from datamodel=Endpoint.Processes where (Processes.process="*wmic* qfe*" OR Processes.process=*systeminfo* OR Processes.process=*hostname*) by Processes.user Processes.process_name Processes.process Processes.dest Processes.parent_process_name 
| `drop_dm_object_name(Processes)` 
| eventstats dc(process) as dc_processes_by_dest by dest 
| where dc_processes_by_dest > 2 
| stats values(process) as process min(firstTime) as firstTime max(lastTime) as lastTime by user, dest parent_process_name 
| `security_content_ctime(firstTime)` 
| `security_content_ctime(lastTime)` 
| `system_information_discovery_detection_filter`
```

#### Macros
The SPL above uses the following Macros:
* [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 `system_information_discovery_detection_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.process
* Processes.user
* Processes.process_name
* Processes.dest


#### 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.

#### Known False Positives
Administrators debugging servers

#### Associated Analytic story
* [Discovery Techniques](/stories/discovery_techniques)


#### Kill Chain Phase
* Actions on Objectives



#### RBA

| Risk Score  | Impact      | Confidence   | Message      |
| ----------- | ----------- |--------------|--------------|
| 15.0 | 30 | 50 | Potential system information discovery behavior on $dest$ by $User$ |


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

#### Test Dataset
Replay any dataset to Splunk Enterprise by using our [`replay.py`](https://github.com/splunk/attack_data#using-replaypy) tool or the [UI](https://github.com/splunk/attack_data#using-ui).
Alternatively you can replay a dataset into a [Splunk Attack Range](https://github.com/splunk/attack_range#replay-dumps-into-attack-range-splunk-server)
