#### Description

The following analytic looks for the use of Mimikatz command line parameters leveraged to execute pass the ticket attacks. Red teams and adversaries alike may use the pass the ticket technique using stolen Kerberos tickets to move laterally within an environment, bypassing normal system access controls. Defenders should be aware that adversaries may customize the source code of Mimikatz and modify the command line parameters. This would effectively bypass this analytic.

#### Search

```

| tstats `security_content_summariesonly` count min(_time) as firstTime max(_time) as lastTime from datamodel=Endpoint.Processes where (Processes.process = "*sekurlsa::tickets /export*" OR Processes.process = "*kerberos::ptt*") by Processes.dest Processes.user Processes.parent_process Processes.process_name Processes.process Processes.process_id Processes.parent_process_id Processes.parent_process_name

| `security_content_ctime(firstTime)` 
| `security_content_ctime(lastTime)` 
| `mimikatz_passtheticket_commandline_parameters_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 `mimikatz_passtheticket_commandline_parameters_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.dest
* Processes.user
* Processes.parent_process
* Processes.process_name
* Processes.process
* Processes.process_id
* Processes.parent_process_id
* Processes.parent_process_name


#### How To Implement
To successfully implement this search, you need to be ingesting logs with the process name, parent process, and command-line executions from your endpoints. If you are using Sysmon, you must have at least version 6.0.4 of the Sysmon TA.

#### Known False Positives
Although highly unlikely, legitimate applications may use the same command line parameters as Mimikatz.

#### RBA

| Risk Score  | Impact      | Confidence   | Message      |
| ----------- | ----------- |--------------|--------------|
| 36.0 | 60 | 60 | Mimikatz command line parameters for pass the ticket attacks were used on $dest$ |


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