Make sure you also post a concern on GitHub if you’ve found a bug or if you would like be certain that your request are going to be tracked and never forgotten.
I shortly started off referring to your thought as "usbstar" in my non-public notes and envisioned that It will be shaped a little something like A 3-pointed Variation with the Throwing Star LAN Faucet. I wished it to have a few details with just one USB port Every single for utilizing Meddler-in-the-Middle (MitM) or Energetic monitoring. A person port might be connected to a concentrate on host, A different to the focus on system, and the final for the keep track of/Manage host.
Combined with LUNA gateware and Facedancer libraries, Cynthion becomes a flexible USB research and growth Device. Facedancer makes it swift and simple to develop or tamper with actual
This customization maximizes case density for robust safety and an unusually strong truly feel – without having compromising Cynthion's little dimensions or light bodyweight.

Facedancer makes it fast and easy to make or tamper with true USB products—not just emulations—even if you don’t have expertise with digital-components structure, HDL, or FPGA architecture!
The Cynthion challenge—like its hardware, gateware, firmware, and program—has become created and Increased while in the open on GitHub. You could look at its annotated hardware models on GitHub, and its developer documentation on ReadTheDocs.
(MitM) functionality offers you the opportunity to manipulate USB details, as it passes among the host and a tool, so that you can "see what takes place" when a tool deviates from founded protocols.
When picking a reputation for this components System, we wished to select anything moon-connected like LUNA. As we scrolled lists of moon-connected terms, “apocynthion” and “pericynthion” stood out to us.
Working with Cynthion's flexible USB stack, you can certainly produce non-compliant visitors with which to fuzz a range of hosts – or the application and motorists functioning on Individuals hosts!
0 PHY chips. The concept was to get what we experienced learned from Daisho but to scale its USB capabilities down to an individual board which was more simple and more inexpensive.
Three USB ability switches help you Handle energy to and from the ideal-aspect USB connectors, thereby facilitating managed electric power cycling of USB-powered equipment beneath Investigation.
Apollo: the firmware that runs on Cynthion's debug controller and that is responsible for configuring its FPGA
USB reverse engineering and stability study. Cynthion hardware and gateware depict a reason-crafted backend for research resources like FaceDancer and USB-fuzzing libraries, therefore simplifying the emulation and speedy prototyping of compliant and non-compliant USB units.
