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.

Leaves skin soft and smells amazing!
Scent: Normal, Size: 18.5 Fl Oz (Pack of 1)
I love this body wash! After using it, my skin feels super smooth and soft to the touch, and it stays hydrated for hours. The scent is light but long-lasting—it smells clean, fresh, and just really pleasant. It lathers well and rinses off easily without any sticky residue. Definitely one of the best body washes I’ve used in a while!

Makes skin smooth
Scent: Rough & Bumpy, Size: 18.5 Fl Oz (Pack of 1)
This is the only body wash I will now use. I have actually gifted it to people because they whine about needing their bath and bodywork’s shower gel and once they use this are like wow! This really does make your skin super soft. It has a clean scent but if you have a shower gel smell you love you can do a little squirt of it with this like my mom does and it still works well.

Very good product for your skin. Frustrating packaging
Scent: Rough & Bumpy, Size: 18.5 Fl Oz (Pack of 1)
The Oil of Olay Super Serum Body was does exactly what you would expect from Olay. It is high quality. It refreshed my dry skin nicely without leaving an oily film on my body. The scent is light an very nice. I use it everday and it keeps my skin moisturized. The one thing I hate about this product is the annoying way it needs to be opened initially. To unseal it you need to tighten the cap to the bottle and then spin the spout about 20 times until it pops. This is not intuitive and can be very confusing. Pros - Great Moisturier, Nice Smell, easy to Pump Cons - Hard to open for some, little pricier tan competitors

Helps my super dry KP skin- worth it!
Scent: Rough & Bumpy, Size: 18.5 Fl Oz (Pack of 1)
My KP is pretty bad lately and I was absolutely hating my skin. I’d liked Olay’s night time retinol in shower body moisturizer that it seems they’ve discontinued and I was kinda hyped for this product. One pump gives you plenty of product, it gets plenty of lather in my shower pouf and the foam is really nice. Normally every body wash dries my skin out no matter how hydrating, I can *almost* skip moisturizer with this. I was pretty overwhelmed by the scent though, it’s VERY strong and lingers a long time- I wish they’d make a toned down version. Within a week I did notice the texture of my skin was less dry and the redness was much better. It works so well though that I bought the body cream in the jar too and am eyeing other products in the line. I just wish it smelled like the body cream, the body wash is blue and smells very woodsy and almost masculine and like I said, lasts a long time, which is great if you like it! However even my objection to the smell can’t get me to rank it less when it works so well improving my skin’s texture and appearance so much. I think the price point is fair for something that ACTUALLY WORKS.
