Task 1: Getting Started

Prerequisites 

Before jumping into this room, there are some prerequisites to complete the challenges:

  1. C programming language
  2. Assembly language (basics)
  3. Some experience in reverse engineering, using debuggers, understanding low-level concepts
  4. Python scripting and pwntools
  5. A lot of patience

These are the things you're going to learn in this room:

  • Buffer overflow
  • Modify variable's value
  • Return to win
  • Return to shellcode
  • Integer Overflow
  • Format string exploit
  • Bypassing mitigations
  • GOT overwrite

Start the Machine

If you feel you're ready to enter the land of pwn and pain click the Start Lab Machine button to get started. Please allow around 5 minutes for all the challenges to become available.

I hope you enjoy this room. Keep an eye out for more binary exploitation challenges in my next room.

Important Note

You're working with a Ubuntu 20.04 LTS VM, so there will be stack alignment issues, make sure to add a ret gadget to solve it.
