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.

Maybe you can patch this..?

?

IDA for the win

This is designed as a very simple Reversing Challenge for someone new to reversing. Once you solve this then work your way up through the challenges with increasing point values, I tried to design them so they increase in complexity.

Yep, definitely plenty of challenging ones on here too if that's what you are looking for!

the real resource that may help you a little bit :-) https://www.youtube.com/watch?v=nLp3hr6Jf2M

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.
