This is the 4th in a series of Beginner Reversing Challenges. If you are new to Reversing, you may want to solve Reykjavik, then Riyadh then Rangoon before solving this challenge. This is a 20 point challenge and is different in two ways from the previous 10 point challenges. Once you get into gdb, b *main+offset is your friend! Good Luck!

Once you solve the challenge you can use the flag to decrypt the souces.zip.enc file provided, if you are interested in seeing the source programs used to create the challenge.

The readme file includes some online resources if you are new to Reversing and Assembler.

    Congrats on being the first solver ebouteillon!

    Note for beginners: this challenge can be solved without gdb ;) Ghidra is enough

  • elliot_pwn

    Decompilers can make things much easier to see ;)

      And the cool thing about Reversing is that decompilers really are not cheating either :-)

    Maybe it was experience from the other challenges but I solved this one in less than half hour with Ghidra + python. It was fun though.

      Great, let me know how you like my other reversing challenges. Each one is designed to get a little more difficult, but Rouen and Rainbow are a lot more difficult than the others.
