Hack the Box (HTB) machine walkthrough series — Irked

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 Irked.

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 Irked, is retired.

The walkthrough

1. Download the VPN pack for the individual user and use the guidelines to log into the HTB VPN.

2. The Irked machine IP is 10.10.10.117.

3. We will adopt the same methodology of performing penetration testing. Let’s start with enumeration in order to learn as much information 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 irked 10.10.10.117>>

5. As we can see, ports 22, 80 and 111 are discovered.

6. Let’s start the enumeration on port 80. Below is the landing page. One hint the page gives is that IRC is working on this box, but the initial Nmap scan does not reflect that. That indicates that we need to perform a full port scan as well.

7. Launching a full-blown scan on the box reveals the following IRC ports. It looks like the service UnrealIRCd is running on the box. The interesting part is that this same service is on three ports.

8. Back to enumeration of the image on port 80. Download the file and run (Read more...)
