Cool challenge

Thanks!

took me the most time a i thought it might be better to learn assembly or this challenge <sed emoji>x3 ... but a fun challenge... took some head scratching and the answer appered suddenly out of frustration when i just kept pressing enter..

using gdb with gef makes this a breeze. I was stuck with plain gdb too.

Thanks! This was a fun challenge to create.

This problem is loosely based on this example from LiveOverflow on YouTube: https://www.youtube.com/watch?v=VroEiMOJPm8

A smart challenge for beginners, with more than one way to be solved. Nice job, kcbowhunter!

do not try to get the flag in a few minutes, take your time to know what is happening... step by step

This was my first ever RE challenge and it was awesome thank you!

Glad you liked it... I tried to design it for people new to Reversing. Thanks for solving it!

You're welcome :-)

It's was good RE challenge. Myself being a beginner, I found this interesting. As for the tools, I found the interface of ghidra a little overwhelming and I stumbled upon a new tool "Cutter"while googling. It also uses ghidra and radare2 in the background but it much better to use.

Thanks for the feedback, sounds interesting.
