So, I'm in this Discord server and somebody by the name [@credmp](https://twitter.com/credmp) thought it'd be a great idea to do an advent calendar of CTF challenges. Every day of december, up until christmas, a new challenge will open up. It starts out easy, accessible to anyone and will grow in complexity as time progresses.

For me, this will be a good opportunity to share some insight in these kind of challenges for people who aren't familiar with them.

To get an overview of all my writeups for this CTF, go [here](/tags/adventofctf/).

## What is a CTF?

CTF stand for Capture The Flag, it's a kind of information security competition that challenges participants to solve a variety of puzzles. The challenges range from a scavenger hunt on wikipedia to basic programming exercises, to hacking your way into a server to steal data. In these challenges, you are usually asked to find a specific piece of text that may be hidden on the server or behind a webpage. This text is called a flag, hence the name "Capture The Flag".
