An medium box by Cyb3rb0b. Oh how I had a hard time with the initial compromise on this one. That being said while I found it rough it was a great learning experience. Additionally, I found it really useful for studying for my OSWE since it let me do a bit of scripting.
As this box is still active the walkthrough is not available.
