Lazy Game Challenge
30 points Easy

I found an interesting game made by some guy named "John_123". It is some betting game. I made some small fixes to the game; see if you can still pwn this and steal $1000000 from me!

To get flag, pwn the server at: nc thekidofarcrania.com 10001

This is why it is important to always check for edge cases.

So i have no idea how to pwn a server. Can someone help me out by listing some literature i could read or something? Do i need to use netcat for this? what does netcat do?
