Cynthion USB Analyzer

Cynthion USB ANALYZER

A multi-tool for building, analyzing, and hacking USB devices

Making USB Accessible

Cynthion is an all-in-one tool for building, testing, monitoring, and experimenting with USB devices. Built around a unique FPGA-based architecture, LUNA’s digital hardware can be fully customized to suit the application at hand. As a result, it can act as a no-compromise High-Speed USB protocol analyzer, a USB-hacking multi-tool, or a USB development platform.

Out-of-the-box, Cynthion acts as a USB protocol analyzer capable of capturing and analyzing traffic between a host and any Low-, Full-, or High-Speed (“USB 2.0”) USB device. It works seamlessly with our open-source analysis software.

Combined with our LUNA gateware and Facedancer libraries, Cynthion becomes a versatile USB-hacking and development tool. Facedancer makes it quick and easy to create or tamper with real USB devices—not just emulations—even if you don’t have experience with digital-hardware design, HDL, or FPGA architecture!
