Rangoon
10 points Easy

This is the third in a series of introductory Reversing Challenges; Reyjkavik, Riyadh and Rangoon. These are designed for people new to Reversing. A little gdb, C and Assembler knowledge should be enough to solve this challenge. Good Luck!

Note that once you solve the challenge, you can use the flag to decrypt the source file used to create the challenge if you are interested in seeing the original C program.

The LiveOverflow channel on YouTube has some great tutorials on reversing, this video has almost everything you need to solve this challenge: https://www.youtube.com/watch?v=VroEiMOJPm8

It took me more than I expected :/ I believe this approach is an original one, for sure it is not perfect — “search and brute” (example script: https://github.com/JanKrasodomski/simple-python-brute-force/blob/283b54f71dcd3dcfa2a52142a75e28f1e7d83f57/simple_brute.py).

Really Enjoyed This Challenge :) But Doesn't Seems to require Dynamic Analysis, as specified in some comments

I have used Cutter to solve it though

I really enjoyed solving this one. Thanks!

This challenge is definitely worth more than just 10 points :/

I made it 10 points because it is a very simple reversing challenge. I understand that is more complex than RubberDuck which is also only worth 10 points.
