Hello hackers, I hope you are having a great end of the year 🎉 ! This article is a meta-article (thought it sounded cool) for the Advent Of Cyber 2023 from TryHackMe. You will find here the link to my writeups for all 4 side quests.

FYI, it was an event that took place in December 2023. Each day before Christmas, one challenge was released with a new topic about cyber security explained and you apply the knowledge directly in a small lab. In some of these labs, QR codes were hidden that lead to the 4 side quests that were significantly harder than the normal AoC.

The link to the general Advent of Cyber 2023, more geared towards beginners (but we can all learn new stuff, a lot of different subjects, I completed it and highly recommend !) : https://tryhackme.com/room/adventofcyber2023.
