Here I will be publishing my writeups from internationals hacking & programing competitions.
In this challenge, our task is to gain access to the privileged commands in communication protocol (based on a real one used by ESA) what will give as a possibility to Hack-A-Sat.
Controller (PWN)
Ret2Libc, Reverse engineering, Integer overflow and programming in Python

Stylish (WEB)
What can happen if we give users ability to change the color on the website. Oh... hack into administrator account, how is this even possible???

SeaEssAreEph is a funny WEB challenge where our goal is to hack a bank, get money and buy a flag. And everything only because of missing CSRF Token.
