**KCA CTF - 2022**

Hi, this is the first time I have written a writeup on a ctf, many more to come. the challenge I did was on a buffer overflow. Now buffer overflow in layman terms is when a program is giving too much data, think of it as when someone eats above their limit they are gonna have to you know... so in propinquity an attacker can overwirte exisiting data, alter it and corrupt it.

At first I just typed in a lot of characters but it wasn't to the over the limit, on the video link below I noticed that he typed consecutively just AAAAA... and i tried that and it worked. this was one of the simple challenges of the ctfs but everyone starts somewhere.
