    I mean, it's a really cool demo of how to essentially engineer these exploits...... and very well presented. My only question is how you would have tackled this (if possible) without the binary being so generous and providing the welcome address?

    Nice man. Never seen you do buffer overflows before. There tuff, I haven't gotten that far in my studies yet. But you explained it well. Seems like Ghidra is making reversing easier for everyone.

      GHIDRA is definitely awesome. I'll try to upload and showcase more reverse engineering and binary exploitation videos. Thanks for watching! :D
