Challenge
Getting Started in the Lab Environment
Here are the initial instructions and explanation of the lab environment. Read this while your environment is busy creating itself from nothing. Yes, this violates physics; we know. How fun!
-
Challenge
Fuzzing the Vulnerable Binary
To start, you will interface with the vulnerable application and fuzz the vulnerable parameter. You will identify the bytes required to exploit the application and understand how to handle and trace the exceptions in a debugger.
-
Challenge
Controlling Execution Flow
In this challenge, you will build upon the identified exploit condition to control the instruction pointer, identify bad bytes, enumerate a jump point, generate and execute shellcode to obtain remote code execution.

Challenge
The Last Challenge
In this challenge, you will be able to reproduce the same type of attack against a different binary.
What's a lab?
Hands-on Labs are real environments created by industry experts to help you learn. These environments help you gain knowledge and experience, practice without compromising your system, test without risk, destroy without fear, and let you learn from your mistakes. Hands-on Labs: practice your skills before delivering in the real world.
