Raven 1: CTF Walkthrough

­In this article, we will attempt to solve a Capture the Flag (CTF) challenge which was posted on VulnHub by William McCann.

According to the information given in the description by the author of the challenge, this is a beginner/intermediate-level Capture the Flag Challenge (CTF). The target of the CTF is to get the root access of the machine and read the flag files. It has four flags which should to be collected to complete the challenge. You can use this link to download the VM and launch it on Virtual Box. The torrent downloadable URL is also available for this VM and is given in the reference section at the end of this article.

For those who are new to CTF challenges and are not aware of this platform, VulnHub is a well-known website for security researchers. It provides users with a method to learn and practice their hacking skills through a series of challenges in a safe and legal environment.

Please Note: For all of these machines, I have used Oracle Virtual Box to run the downloaded machine. I will be 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.
