Another entry level Reversing challenge, if you are new to Reversing you probably want to try my Reyjkavik challenge before attempting this challenge. Good Luck! The flag is hidden inside the Riyadh program. Solve the Challenge, get the flag, and I have included the encrypted sources used to create the challenge in the Riyadh.zip file. If you do to the work of solving the Challenge, I'm providing the Challenge source code (C++ and Python) if you are interested in studying the sources after solving the challenge. I think this is a great way to improve your Reversing skills when learning. Please don't share the sources or flag after you solve the challenge.

It's intended to be an easy problem to help get started in reversing. There are lots of other more difficult problems for you :-)

Congrats for hanging in there and solving it. Ghidra is a great tool for helping with Reversing problems if you haven't tried it yet.

Another really good one. I learn more and more about GDB with each of these challenges, it's really a great introduction to reverse engineering.
Thanks!
