Hack Challenge Redo (part3)

We had a small break with our hacking challenges Redo. The format of the Meetup required a change, to accommodate for less experienced visitors. And as much as I love the SANS Institute Challenges, they tend to be quite a puzzle, especially later one. So for now, we are going to focus on couple other Hacking Challenges that are available online. And hopefully in December, when new 2022 SANS Hack Challenge starts, we will have a group ready to battle it together 🙂

Let’s start from Over the Wire. There are plenty games there, we will start with the Bandit, as most suitable to get used to the platform. Bandit offers 33 levels to play, it teaches Linux commands and tools. In each level your goal is identical, find a password to the next level, but let’s start from the beginning.

To play Bandit you will need to establish SSH connection to the Over the Wire lab server, all details of connection are given in Level 0.

So, what is SSH?

Secure Shell, sometimes referred to as Secure Socket Shell, is a protocol which allows you to connect securely to a remote computer or a server by using a text-based interface. When a secure SSH connection is established, a shell session will be started, and you will be able to manipulate the server by typing commands within the client on your local computer. System and network administrators use this protocol the most, as well as anyone who needs to manage a computer remotely in a highly secure manner.

How to use SSH on Windows?

Most common ways of using SSH on Windows is by using one of the clients. Most popular clients are: PuTTY, BitwiseSSH and OpenSSH. Windows 10 users have now the option to use build-in OpenSSH client. Just follow the installation details of your choose client.

How to use SSH on Mac?

Mac’s have build-in Terminal feature, that provides SSH client.

How do we do it on Linux?

That shouldn’t be a problem for any regular Linux users, but in case you are just starting with Linux. Go to your terminal and type:


This should list all ssh details and commands. If that’s not the case, just use the following command to install OpenSSH:

sudo apt-get install openssh-client

Full list of common SSH flags can be found here.

This should get everyone started and ready for this week challenge 🙂

One more thing, you may need to use Vim and couple Linux commands.

See you @ 5-7pm today @ our dedicated Discord channel.
