TSGrinder – Brute Force Terminal Services Server

July 22, 2008 – 6:11 AM

This is a tool that has been around quite some time too, it’s still very useful though and it’s a very niche tool specifically for brute forcing Windows Terminal Server.

TSGrinder is the first production Terminal Server brute force tool, and is now in release 2. The main idea here is that the Administrator account, since it cannot be locked out for local logons, can be brute forced. And having an encrypted channel to the TS logon process sure helps to keep IDS from catching the attempts.

TSGrinder is a “dictionary” based attack tool, but it does have some interesting features like “l337″ conversion, and supports multiple attack windows from a single dictionary file. It supports multiple password attempts in the same connection, and allows you to specify how many times to try a
username/password combination within a particular connection.
