    Crack-a-Mateo (Crypto Challenge Writeup) -- JerseyCTF IV 2024

    Once again JerseyCTF returns in its IV edition, with a total of 65 challenges so that more than 1600 players in more than 800 teams participated in this event, players of all categories from beginners to experts could enjoy 24 hours of entertainment. I chose this challenge for the write-up because of its simplicity. Many people are unaware that it is possible to create custom unique password candidates based on personal details like birthdays and names, so we must be cautious with the information we share on social networks, and most importantly, we must know how to choose our passwords very well!

Personally, I really enjoyed the Forensic challenges (I managed to do them all) and this challenge in particular seemed very well planned and that it can be used to teach how to carry out a forensic investigation.
