What is a CTF?
In a Capture The Flag (CTF) competition, the goal is to obtain the 'flag' by hacking into a vulnerable system.
For example in web challenges, you have to break into a website to obtain the flag. Whereas in cryptography,
you have to break the encryption to obtain the flag.
The flag is a string of text that you submit to the competition platform to score points. It usually looks something
like this:
FLAG{4N_ExaMplE_fl4G}
This flag can then be handed in to the competition platform to score points. The team with the most points
at the end of the competition wins.
