Here’s a travel post from one of our members, Jeffrey, who recently spent a week off-grid (and delightfully offbeat) at Electric Wonderland — a 7-day international maker/hacker camp in the Croatian countryside. Combining art, technology, science, nature, and community, the camp is built around DIY, DIWO, and DITO culture. Think campfires and coding, soldering and skywatching.
Electric Wonderland is run by Radiona, a hackerspace we’ve built strong links over the years through exchanges, visits, sharing of ideas, and plenty of friendships.
But before we get to the forest…
🎥 Pre-Camp: Days -3 to 0 – Zagreb Warm-Up
Day -3 (Friday 18) Back in Zagreb, a city I’ve grown to love visiting over the years. This time, I was travelling with my mother again (link to FAB25 trip). I dropped into FabLab Zagreb to see my friend Richard and the crew — always great to catch up.
The last time I spent time with them was during my island-hopping trip along the Croatian coast (link).
Day -2 (Saturday 19) Beat the heat with a morning gym session, then squeezed in some geocaching, ice cream, a tasty vegan lunch, and a visit to the Zagreb Cat Café — where I made more furry friends than I could count.
This post is from our member Jeffrey Roe, who is sharing his trip to Croatia. Over about a week, Jeffrey gave talks at conferences, got stuck into maker events, visited fab labs and hackerspaces, and even managed a bit of island hopping. Here’s how it all went.
Day 1: Landing in Zagreb
After touching down in Zagreb, I had some time to get my bearings and settle in. It’s a lovely city, and I was looking forward to a busy few days ahead. The Science Connecting People (SCOPE) Conference kicked off with a half-day session in Europe House.
Every few years we go on our travels and normally every two years we visit Electromagnetic Field. Due to the pandemic, it has been long overdue.
EMFCamp takes place from the 3rd of June until the 5th of June in Eastnor, UK. We come together with other people with a connection to Ireland to form the Irish Embassy.
Think of it as a bit of a home base during the event. As is the tradition we link up with the Scottish Consulate and Milliways to form a larger super village.
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:
ssh
This should list all ssh details and commands. If that’s not the case, just use the following command to install OpenSSH:
On the 23rd of January Meetup we have completed following tasks:
Objective 1 – Uncover Santa’s Gift List – clues in blog post video above
Objective 2a – Kringle Kiosk – clues in blog post video above
Objective 2b – S3 bucket – clues give at a Discord were: update the wordlist and add the searched bucket name, use ‘cat’ command to inspect the bucket. Copy and inspect in CyberChef the file. Start unpacking and remember to pipe the output whenever needed.
Objective 3a – Linux Primer – no clues were needed 🙂
Objective 3b – Point-of-Sale Password Recovery – clues give at a Discord were: download the package, no need to install the shop. Unpack the exe file, and poke around until you find app.asar and use 7zip to open Asar file.
Later today, 5-7pm GMT we will be focusing on following tasks:
all unfinished past tasks
Objective 4a – Unescape Tmux – no help needed
Objective 4b – Santavator operations – no help needed
Objective 5a – Speaker UNPrep – first clue: ‘strings door’ with some filters, more clues @Discord
Objective 5b – 5b: 33 Gkbps – no help needed
Objective 5c – Open the HID lock in the Workshop – no help needed

So, as promised we are going to start SANS Holiday Hack Challenge Redo run by Counter Hack Team. We will start with the latest 2020 challenge . You will need a valid email to create user account, which is instant. You can start straight away on your own or watch a couple helpful videos.
The first video that I would like talk about, it’s Ed Skoudis 2020 Hack Challenge Intro. Video is a great overview of this year challenge.
Second video is aimed at Hack Challenge first timers, it’s walk through the login page and the starting interface.
