This exercise is designed to test your skills and understanding of binary exploitation and reverse engineering. You will need to work through a series of binary exploitation challenges using a provided virtual machine.
1. Download the virtual machine image [hole-in-bin.ova](https://assets.01-edu.org/cybersecurity/hole-in-bin/hole-in-bin.ova). This image contains all the binaries you will need to exploit.
Inside the `/opt/hole-in-bin` directory, you will find a set of binaries (ex00 to ex11) that you need to exploit. Each binary presents a unique challenge and will test different aspects of your knowledge about binary exploitation and reverse engineering.
You can find more details in a `README.txt` file inside each exercise folder.
Your task is to exploit these binaries, following ethical hacking guidelines.
> ⚠️ These methods and tools are for educational purposes only, so that you have a better understanding of how to protect against similar vulnerabilities. You must ensure that you do not attempt any exploit-type activity without the explicit permission of the owner of the machine, system or application. Failure to obtain permission risks breaking the law.
> It's forbidden to use external scripts, in the audit you will be asked different questions about the concepts and the practices of this project, prepare yourself!
