SpoolSample is a C# proof-of-concept tool that coerces Windows hosts to authenticate to arbitrary machines via the MS-RPRN Print System Remote Protocol RPC interface. It is used in penetration testing to trigger authentication for relay or capture attacks against Active Directory environments.

Use cases

  • coerce a Windows host to authenticate to my machine
  • trigger NTLM authentication via the printer spooler service
  • capture or relay credentials during a pentest
  • demonstrate MS-RPRN authentication coercion in Active Directory
  • test whether a domain controller is vulnerable to spooler coercion attacks

When to choose

  • you are performing authorized penetration testing or red teaming against Windows/Active Directory
  • you need a simple, proven PoC for MS-RPRN-based authentication coercion
  • you want a lightweight C# tool that runs on Windows with .NET

When to avoid

  • you need a supported, maintained security product rather than a proof-of-concept
  • your target has the Print Spooler service disabled or patched
  • you lack authorization to test the target environment
