Cool!! This is an easy category for Reversing, but for newbie like me, it's really difficult. Please, anyone can make the video to solve this for beginner, especially to use ghidra or something to Reversing

CONGRATULATIONS!! You found the flag: abcdefghijklmnopqrstuvwxyzabcd The code printed it lol

Thank you very much

I really enjoyed challenge. Thank you very much

You're welcome, I'm glad you liked it. Have you tried my Dune reversing challenge?

After my Operating Systems course I swore I'd never look at Assembly again, but these are so fun. Took me a day to figure out how to set registers in gdb, but got there eventually!

glad you enjoyed it

This one was a piece of cake after solving Reyjkavik XD This was a great challenge, if with Reyjkavik I learned about GDB a lot, this time I used those same skills to solve it, no 90% time spent on reading and watching tutorials

Thanks!

This was very interesting. Took me a day to figure it out but I'm a complete noob (started learning reverse engineering 3 days ago). Learned a lot.

Congrats for hanging in there and solving it. Ghidra is a great tool for helping with Reversing problems if you haven't tried it yet.

Another really good one. I learn more and more about GDB with each of these challenges, it's really a great introduction to reverse engineering.

Thanks!

Which tool did you use?

I did exactly the same as mkay, only used gdb.
