HTB Cyber Apocalypse 2022 CTF

Hack The Box organized a Capture The Flag (CTF) event to which I participated with few friends: Cyber Apocalypse 2022

A CTF is a hacking based game providing different cyber security puzzles. Puzzles are organized in categories, such as web, pwn, reverse, crypto, etc. Solving a puzzle gives a unique (and unguessable) character string that will be exchanged for points. Points are given according to the difficulty of a puzzle, and the number of other teams solving it: to score higher points you must be the first one to solve a challenge!

CTF events can be attended alone or with a team. This event was great, thanks to Hack The Box!

Below are our version of the challenges we could solve.
