ELF Format Cheatsheet

Introduction

Executable and Linkable Format (ELF), is the default binary format on Linux-based systems.

Compilation

I played Harekaze Mini CTF 2020 for about 3 hours this weekend. The pwn challenges were nice (I especially enjoyed nm-game-extreme). Here are some short writeups.

shellcode

The program just tells you to provide shellcode that will execute execve("/bin/sh", NULL, NULL). It gives you the address of the "/bin/sh" string, so you just create shellcode to do the job and send it:

#!/usr/bin/env python3
