@RealTryHackMe #AdventOfCyber Series: Challenge 21 – Needles In Computer Stacks #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 twenty-first challenge, we’re presented with a scenario where McBlue wants to use automation to detect malicious files on the network. Great idea!

The topic explored in this challenge is the tool YARA. YARA is a tool that is used to match patterns in potentially malicious files. The tool can be used to as a detection aid for malware analysis. Which will be helpful in our challenge.

Can McSkidy find the malicious file(s) in the network? Find out below!
