Chuckle requires a few tools to work:
- Veil (latest version from git)
- Responder (Chuckle will detect which version you are using.)
- Nbtscan (unixwiz)
Wait a while or coax a prvileged user into authenticating against you and you should end up with a shell on your target machine.
Be careful when running this and never run on a network you are not permitted to do so.
