Infinition’s project, Bjorn, offers an innovative twist on Raspberry Pi-based network assessment tools, blending serious functionality with an engaging, game-like interface. Designed to work primarily with the Raspberry Pi Zero W or Zero 2 W, Bjorn transforms pen testing into an interactive experience, featuring a Viking mascot that adds a touch of personality and fun.
Bjorn isn’t just about aesthetics. It’s a robust network tool capable of scanning for open ports, identifying vulnerabilities, and even executing brute-force attacks on protocols like FTP and SSH. It can also exploit network vulnerabilities to extract files. While its functionality is powerful, the system’s charm lies in the Tamagotchi-like UI: as users perform actions, the Viking mascot reacts with animations and levels up based on the tasks completed.
The hardware requirements for Bjorn include a Raspberry Pi with wireless support. Though optimized for the Pi Zero W series, the project has reportedly been successfully run on other models like the Raspberry Pi 3B+. A Waveshare 2.13-inch e-Ink display hat is recommended for output, enhancing the portable and visually appealing design.
Bjorn is open-source, meaning enthusiasts can recreate it at home by following the instructions available on its GitHub repository. It’s worth noting that the tool is designed for ethical hacking and should be used responsibly to avoid any illegal or unethical activities.
By combining technical utility with a playful interface, Bjorn offers a fresh perspective on network security tools. It’s a great example of how creativity and functionality can come together to make even the most serious tools approachable and enjoyable.
