Recently, I took on an exciting project – turning a Raspberry Pi Zero 2 W into a powerful cybersecurity tool. My goal was to create a portable, low-cost device capable of network analysis, security testing, and automation.
During my research, I discovered Bjorn, an open-source project designed specifically for embedded devices like the Raspberry Pi Zero. Bjorn is a powerful network scanning and offensive security tool for the Raspberry Pi with a 2.13-inch e-Paper HAT. It discovers network targets, identifies open ports, exposed services, and potential vulnerabilities. Bjorn can perform brute force attacks, file stealing, host zombification, and supports custom attack scripts. Following the project’s official instructions, I built the system step by step on my Raspberry Pi Zero 2 W.
How did I do it?
You will find the answer to this question in my YouTube video. You will find there a tutorial that will explain step by step how I built it and a lot of advice because I came across a lot of errors and in the video I show how I solved them.
Why Raspberry Pi Zero 2 W?
The Raspberry Pi Zero 2 W is an incredibly compact but capable device. It features a quad-core Cortex-A53 processor, 512MB of RAM, and built-in Wi-Fi and Bluetooth. While not as powerful as full-sized Raspberry Pi boards, but it is much cheaper and it offers just enough processing power to handle lightweight cybersecurity tasks while maintaining portability and discretion. Its affordability makes it an excellent choice for DIY security projects.
I also built this little Viking on Raspberry Pi 3. It works the same way but doesn’t look as compact. Thanks to the Raspberry Pi zero 2 W Bjorn gained more mobility because I can connect it to a power bank and take it wherever I want and it will still work. Thanks to its low power consumption it can even work for a few days without charging.
Where to find Bjorn?
The project is still in alpha version, but if you are interested, you can find more information about it on Github.
