Walkthrough for Blocky - A Vulnerable Machine [HackTheBox]
This is probably one of the longest videos on my Youtube channel. Still waiting for @dtube to become a reliable platform (I've been waiting for months) so that I can keep uploading my videos there without getting an error at upload.
Anyway, this video is another demonstration for how to get into a server as unprivileged user (through some vulnerable service) and escalate privileges to the root account - ultimately owning the server.
The attack vector was pretty straight-forward: leaking credential within files hosted on the server. That's how I got in. Privilege escalation can then be done in more than one ways. I only demonstrated two ways in this video.
I hope you learn something from this demo, something that will enable you to better protect your servers.
