Rayhunter is an IMSI Catcher Catcher specifically designed for the Orbic mobile hotspot, with a disclaimer that it’s only a proof of concept and should not be used in high-risk situations. The code is tailored for the Orbic RC400L mobile hotspot, but may work on other Orbics and Linux/Qualcom devices. The installation process involves downloading the latest release bundle, extracting it, and running the install script for your platform. Rayhunter runs automatically on the Orbic device once installed, providing a web UI for functions like starting/stopping recordings, downloading captures, and viewing analyses. Access the UI either over WiFi or USB connection. Development instructions are provided for ADB installation and rooting the device. Use at your own risk.
