This was really fun. A little challenging. Loved it!

It's not so easy for beginners.

Wonderful!. I always hesitate to go towards the RE side but this challenge made me interested. its really nice. I loved it. I got nice hands on in gdb too.

Glad you liked it... I'm a begging in RE myself and creating these challenges helps me to learn too.

I over complicated it ; - ;, but good as a start should listen to the instructions

gdb-peda makes this a lot easier

remember to use gdb-peda not gdb bcs it is bad

Cool

Glad you liked it.

Cool challenge

Thanks!

Congrats! Unfortunately these reversing challenges have a steep learning curve; C, assembly, GDB / Ghira etc. Congrats on hanging in there!

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.
