Description
This used to be a simple pwn challenge. But someone patched it and the win function doesn't print the flag anymore, can you still get it? If this is the first time doing binary exploitation, this challenge might feel a bit overwhelming. But don't worry, I have attached the first challenge from two years ago and a README for it. If you solve that one, you should be able to solve this one as well with a bit of tinkering. If you feel stuck, feel free to ask for help in the discord server.

Description
Format strings are a powerful tool in the hands of a hacker. They can be used to read and write memory, and even execute code. This challenge is a simple demonstration of how format strings can be used to write memory. Can you use it to get the flag?

Something's wrong with the brontosaurus powering Fred's car. The Dino Control Unit (DCU) is acting up, and the mechanics at the Bedrock Motor Pool can't figure it out. Can you find the reset code for the DCU and help Fred get back on the road?
