Matrix 1: CTF walkthrough

Capture the Flag with VulnHub – Matrix

In this article, we will solve a Capture the Flag (CTF) challenge that was posted on VulnHub by Ajay Verma. As per the description is given by the author, this is an intermediate-level CTF and the target of this CTF is to get the flag.txt file.

You can check my previous articles for more CTF challenges. I have provided a downloadable URL for this CTF; you can download the machine and run it on VirtualBox. The torrent downloadable URL is also available for this VM, and it has been added in the reference section of this article.

For those who are not aware of the site, VulnHub is a well-known website for security researchers which aims to provide users with a way to learn and practice their hacking skills through a series of challenges in a safe and legal environment. You can download vulnerable machines from this website and try to exploit them. There are a lot of other challenging CTF exercises available on vulnhub.com and I highly suggest attempting them, as it is a good way to sharpen your skills and learn new techniques in a safe environment.

Please Note: For all of these machines, I have used Oracle VirtualBox to run the downloaded machine. I am using Kali Linux as an attacker machine for solving this CTF. The techniques used are solely for educational purposes, and I am not responsible if the listed techniques are used against any other targets.

Summary of the steps

The summary of the steps involved in solving this CTF is given below.

  1. Identifying target host by using the NetDiscover utility
  2. Scanning open ports by using the Nmap scanner
  3. Enumerating the Web application with Dirb and Nikto vulnerability scanner
  4. Learning more about the target (Read more...)
