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, Cynthion’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 research 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, Packetry.

Combined with LUNA gateware and Facedancer libraries, Cynthion becomes a versatile USB research 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!

No extra cables are included! You may need a variety of USB A & C cables to connect to your computer/target.

 

Core Features

Cynthion is a fully reconfigurable test instrument that provides all the hardware, gateware, firmware, and software you need to work with—and, indeed, to master—USB. Below are a few of the challenges to which you can apply your Cynthion:

  • Protocol analysis for Low-, Full-, and High- speed USB. Cynthion provides everything you need for passive USB monitoring. With Packetry USB analysis software, Cynthion provides everything you need for passive USB monitoring.

  • Creating your own Low-, Full-, or High- speed USB device. LUNA provides Amaranth gateware that allows you to create USB devices in gateware, firmware, or a combination of the two. Using the Facedancer library, you can create or emulate real USB devices in high-level Python.

  • Meddler-in-the-Middle (MitM) attacks on USB communication. Cynthion hardware can function as a "USB proxy" capable of transparently modifying USB data as it flows between a host and a device. Each board’s three USB Type-C connections allow for simultaneous, high-speed proxying while maintaining a high-speed connection to the host. As a result, you can proxy a connection with or without the help of a host PC.

  • USB reverse engineering and security research. Cynthion hardware and LUNA gateware represent a purpose-built backend for research tools like Facedancer and USB-fuzzing libraries, thereby simplifying the emulation and rapid prototyping of compliant and non-compliant USB devices. Unlike other USB-emulation solutions, Cynthion-based hardware is dynamically reconfigurable, so it gives you the flexibility to create any endpoint configuration and engage in almost any USB (mis)behavior.

Economically priced ipad case
Color: Mulberry
There's absolutely no way you could find a better ipad case with a wireless keyboard for this price. My daughter loves it. I was expecting it to feel a little cheap because of the price. I was wrong, this is a great find... thanks

Cute but beware of buttons with a mind of its own.
Color: Pink, Color: Pink
Super cute. Only has 3 keyboard multicolor options and one white light setting. Dimmable. But its functionality needs work. But the keys keep doing weird things like skipping lines, changing excel sheet formatting and just moving where I am typing on it own. Like it will be typing and then move to the beginning of the sentence and keep moving. The feel is super light and the quality of the case is great though. It’s easy to use and install to device with Bluetooth. Value is you get what you paid for. This keyboard is cute but not working quite well. I accidentally ordered a different model for a later iPad and had to return it, but based off of a leader model in comparison to this one, the keyboard just isn’t that great

Great Keyboard Case!
Color: Pink
Bought this for the wife for Mother’s Day since she needed a new keyboard and case. She used my old Magic Keyboard but constantly was tired of taking her iPad off, just to rotate it. Bought this and she loves it. Very durable, even with our 2 year old playing with it. Keyboard is bright and is good to use. Just a Bluetooth keyboard setup and it’s all good to go! Definitely great value for the money and something highly recommended for those with an iPad Air or Pro.
