Shellcode Lab (Marco Lux)

| February 17th, 2017

Before you ask: No, i won’t fix your shellscript! %$^&@&!!!!@!@

It seems like in times of msfvenom and alike everyone has forgotten that there was once a way to write your shellcode by your own. Even worse, nowadays people mix up shellcoding with shellscripting.
As you are still reading, you are interested in what shellcoding is or improve your already skillset.
Shellcoding defines the fine task of creating bytes of opcodes, placed in your exploit payload to gain a remote or privileged shell. While shellcode can be used for other tasks as well, the name has kept. So we do will learn and write assembly. Looking into the basics of CPU architecture, learning about Linux Syscalls and how to use them to create our own payloads. This class focuses on 32Bit shellcoding.

The workshop syllabus:

  • 0x1 Intro to 32Bit Intel CPU
  • 0x2 Intro to GDB
  • 0x3 Shellcoding Syscall Basics
  • 0x4 Shellcoding Network Shells
