stack smashing + shellcoding my way to happiness

posted on : 3/12/2025

lately ive been diving deep into shellcoding on pwn.college! i wont post any solutions here because i dont want2 get in trouble or give anyone out the answers, but doing those challenges lately have been really intersting. ive learned a lot about the stack and how it works as well!

ive started to learn how to read some assembly as well, picking up on the gadgets that exist in there. my ccurrent focus is learning how to write rop chains and target gadgets (cve #2 i wwant to be a rop chain bweeeehhhh) my exploitdev dreams edge close r and close r . . . ive also fully learned how basic buffer overflows work and stuff. i want to find and meet friends who know about hacking + offsec +whatever you want to call it but im not too sure on how to do that. attached is a stack dump after a bufferoverflow i did. that was a lot of fun!!

shellcoding has also been really fun / worth it. getting to write out my own has also been interesting! i didn't catalogue the process too well so most examples i have dont work because i kept writingover the one that does (stupid) but here is one that should work!

overall, learning shellcoding, reverse engneering, AND memory errors has been extremely fun and gratify to get to interact with the stack , and i really hope to be able to use this in the future on things that allow me to do more stuff with this #knowledge!
