Bjorn is a network scanning and offensive security tool designed for the Raspberry Pi with a 2.13-inch e-Paper HAT display.
The tool addresses the need for portable penetration testing capabilities by combining network reconnaissance with active attack functionality on compact hardware. It discovers network targets and identifies open ports and exposed services, then performs brute force attacks, file stealing, and host zombification. The e-Paper display provides a low-power interface for monitoring and controlling operations on the device.
Bjorn suits security researchers and penetration testers who want a portable, self-contained platform for network assessment and offensive testing. It works well for authorized security testing in environments where a small, inconspicuous device is advantageous. The tool's support for custom attack scripts allows operators to extend its capabilities beyond the built-in functionality. This approach differs from traditional penetration testing workflows that rely on laptops or larger systems, offering instead a specialized hardware-software combination optimized for the Raspberry Pi form factor.
The project shows active development with regular commits addressing bug fixes, feature additions, and improvements to the scanning and attack modules. Work spans multiple areas including the e-Paper display integration, network scanning enhancements, and the attack framework itself, indicating sustained effort across the codebase rather than maintenance of a single component. The maintainer responds to issues and incorporates feedback into updates.
