Hot Potato Windows Privilege Escalation exploit on PowerShell



Tater is a PowerShell implementation of the Hot Potato Windows Privilege Escalation exploit.


All credit goes to @breenmachine, @foxglovesec, Google Project Zero, and anyone else that helped work out the details for this exploit.

Included In



  • The main Tater function.
  • IP – Specify a specific local IP address. An IP address will be selected automatically if this parameter is not used.
  • SpooferIP – Specify an IP address for NBNS spoofing. This is needed when using two hosts to get around an in-use port 80 on the privesc target.
  • Command – Command to execute as SYSTEM on the localhost. Use PowerShell character escapes where necessary.
  • NBNS – Default = Enabled: (Y/N) Enable/Disable NBNS bruteforce spoofing.
  • NBNSLimit – Default = Enabled: (Y/N) Enable/Disable NBNS bruteforce spoofer limiting to stop NBNS spoofing while hostname is resolving correctly.
  • ExhaustUDP – Default = Disabled: (Y/N) Enable/Disable UDP port exhaustion to force all DNS lookups to fail in order to fallback to NBNS resolution.
  • HTTPPort – Default = 80: Specify a TCP port for the HTTP listener and redirect response.
  • Hostname – Default = WPAD: Hostname to spoof. WPAD.DOMAIN.TLD may be required by Windows Server 2008.
  • WPADDirectHosts – Comma separated list of hosts to list as direct in the wpad.dat file. Note that localhost is always listed as direct.
  • WPADPort – Default = 80: Specify a proxy server port to be included in the wpad.dat file.
  • Trigger – Default = 1: Trigger type to use in order to trigger HTTP to SMB relay. 0 = None, 1 = Windows Defender Signature Update, 2 = Windows 10 Webclient/Scheduled Task
  • TaskDelete – Default = Enabled: (Y/N) Enable/Disable scheduled task deletion for trigger 2. If enabled, a random string will be added to the taskname to avoid failures after multiple trigger 2 runs.
  • Taskname – Default = Tater: Scheduled task name to use with trigger 2. If you observe that Tater does not work after multiple trigger 2 runs, try changing the taskname.
  • RunTime – Default = Unlimited: (Integer) Set the run time duration in minutes.
  • ConsoleOutput – Default = Disabled: (Y/N) Enable/Disable real time console output. If using this option through a shell, test to ensure that it doesn’t hang the shell.
  • StatusOutput – Default = Enabled: (Y/N) Enable/Disable startup messages.
  • ShowHelp – Default = Enabled: (Y/N) Enable/Disable the help messages at startup.
  • Tool – Default = 0: (0,1,2) Enable/Disable features for better operation through external tools such as Metasploit’s Interactive Powershell Sessions and Empire. 0 = None, 1 = Metasploit, 2 = Empire


  • Function to manually stop Invoke-Tater.


  • To import with Import-Module:
    Import-Module ./Tater.ps1
  • To import using dot source method:
    . ./Tater.ps1


  • 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”
  • Two system setup to get around port 80 being in-use on the privesc target
    WPAD System – – 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 –
    Invoke-Tater -Command “net user Tater Winter2016 /add && net localgroup administrators Tater /add” -HTTPPort 8080 -SpooferIP


Windows 7 using trigger 1 (NBNS WPAD Bruteforce + Windows Defender Signature Updates)

Windows 10 using trigger 2 (WebClient Service + Scheduled Task)

Windows 7 using trigger 1 and UDP port exhaustion
