Intro I was part of the CTF challenges admin team, where we worked on creating a CTF competition for our company. I didn’t have much experience with CTF before, so it was interesting to get involved in creating the challenges. There were four main topics I focused on when designing the problems. Btw, the problem titles are movies I recommend. Cryptography I like cryptography, and creating challenges for this CTF was really fun....

Memory and pointer We learned how to declare variables array, vector etc. But how do these things works under the hood? Lets start with memory. All the are stored in memory. For example if we declare array or vector, c++ will allocate new memory, which we can then use directly. If we no longer need these variable, they will be cleaned up automatically, like variables declared within a function. But, how do we know where they are stored?...
