This is a walkthrough of OffSec Proving Grounds machine “Bitest”. It is rated as Intermediate but it was quite difficult and I had to get creative. We start by exploiting rsync and move on to a program called Vitest. Using a very recent exploit poc (2025) we are finally able to get a shell. The shell would only last for 15-20 seconds so I had to think outside the box to get a stable shell and finally privesc to pwn the machine! ***SPOILER***Walkthrough of the machine called “Bitest” in the Offsec Proving Grounds…don’t watch unless you want help getting through the machine.
Haven’t seen any walkthroughs of this one!
