We’ll start with a scan of all open ports with the following command: nmap -p –

Next, we’ll enumerate versions and see if there’s any safe scripts available for those enumerated service versions: nmap -sC -sV -p 22,53,80,1614,32400,32469

We’ll keep this information handy, but for now the most interesting thing for me is port 80, and the other HTTP stuff running on port 32400, so let’s open up our browser and navigate to the website.

So a page comes up, but there’s nothing on it. So let’s enumerate that with gobuster

Enumerating HTTP

We’ll start with a basic enumeration using gobuster: gobuster dir -u -w /usr/share/wordlists/dirbuster/directory-list-2.3-medium.txt

The scan will take a while to go, but within a few moments we see that the /admin directory is available, so let’s navigate there while the scan completes.

Looks like we’re at a page for Pi-hole

Having no idea what Pi-hole is I Googled the default username and password for Pi-hole and came right up with this:

Clicking on the Login button from the Pi-hole page, when I enter raspberry as the password I get a failed login attempt.

Let’s try another way to see if our credentials work, Medusa.


Medusa is a tool that can be used to brute-force logins. But we don’t want to brute force anything (yet) we just want to see if the credentials we have work. My instance of Kali didn’t have it, so I had to install it with sudo apt-get install medusa

You can type medusa to see how to specify the options, and in this instance we’ll need -h for hostname, -u for username, -p for password, and -M ssh to specify the SSH module we’ll try to log in with. Thus, our command looks like this: medusa -h -u pi -p raspberry -M ssh

Looks like we’re good to go, so let’s ssh into the box and log in: ssh [email protected]

So, let’s start by seeing who we’re logged in as, and if we can do sudo with anything.

Cool! Let’s navigate to the desktop and see if we can get the user flag:

Getting Root

We can type sudo bash to get root access and then move to the /root directory and look for the root flag.

So, now we need to look for a USB drive location. Let’s start by moving to /mnt, and then /media

Well, roger that. Let’s move to /dev and look at the sbd file.

From here, you can either use strings or cat to look at the sbd file and get the root flag.
