Hack the Box (HTB) machines walkthrough series — Blocky
Today, we will be continuing with our exploration of Hack the Box (HTB) machines as seen in previous articles. This walkthrough is of an HTB machine named Blocky.
HTB is an excellent platform that hosts machines belonging to multiple OSes. It also has some other challenges as well. Individuals have to solve the puzzle (simple enumeration plus pentest) in order to log into the platform and download the VPN pack to connect to the machines hosted on the HTB platform.
Note: Only write-ups of retired HTB machines are allowed. The machine in this article, named Blocky, is retired.
Let’s start with this machine.
1. Download the VPN pack for the individual user and use the guidelines to log into the HTB VPN.
2. The Blocky machine IP is 10.10.10.37.
3. We will adopt the same methodology of performing penetration testing as we have used previously. Let’s start with enumeration in order to learn as much about the machine as possible.
4. As usual, let’s start with the Nmap scan to gather more information about the services running on this machine. [CLICK IMAGES TO ENLARGE]
<<nmap -sC -sV -oA Blocky 10.10.10.37>>
5. As we can see, ports 21, 22 and 80 are opened.
6. Let’s start the enumeration with port 80. We can see a normal webpage hosted on WordPress.
7. Let’s try to enumerate the directories with gobuster. We can see that we have a lot of WordPress directories hit. After enumerating, we found something interesting in the plugin directory.
<<gobuster -u http://10.10.10.37 -w /usr/share/wordlists/dirbuster/directory-list-2.3-medium.txt -t 20>>
8. We have a jar file. Let’s download it and analyze it.
9. We can just unzip the jar file to inflate the classes within. We can (Read more...)
