# Challenges We are providing two reverse-engineering challenges that will put your skills to the test. Swing by the ManTech booth for information about prizes and other opportunities. ### Simple Crack-Me A crack-me is a small program put together to test the skills of reverse engineers. Every crack-me has different goals and different protections. This simple enough help you get your feet wet, but without being so simple that you can just run `strings` on it. #### Downloads * [Windows](/bins/simplecrackme.exe) * [Linux](/bins/simplecrackme) ### Titulus A simple webserver to be run on your machine, with a simple goal: find the flag. #### Downloads * [Windows](/bins/titulus.exe) * [Linux](/bins/titulus) ### RaceMe This challenge is the hardest of the beginner level challenges. It will require defeating basic exploit mitigation techniques and redirecting the instruction pointer. Download the binary, reverse it, and write an exploit for it to find the flag. When you're ready, come see to test it live. #### Downloads * [Linux](/bins/raceme)
