@RealTryHackMe #AdventOfCyber Series: Challenge 12 – Sharing Without Caring #TisTheSeasonForHacking

Another day, another challenge…

In this post, we’re starting a new series the Advent of Cyber series that is hosted by TryHackMe. This is the third year of the Advent of Cyber where a challenge is released everyday leading to Christmas. In total there will be 25 challenges. In these challenges, we’re McSkidy an elf trying to save Christmas.

In our twelfth challenge, we’re presented with a scenario where there’s one server that has unusual traffic. We suspect Grinch Enterprises has been leaving traces of their exploits on our server. We must investigate this server to see what data we can extract.

The topic explored in this challenge was Network File System (NFS). NFS is a protocol that allows us to transfer files from one computer to another. It’s available on Windows and Linux. Which makes it easy to us NFS to share files between the different operating systems.

Can we use the information we learned about NFS to find the data we’re looking for?

Well… click the below video to find out!
