Cynthion
209,00 €
The Cynthion is an all-new, highly capable USB-hacking multi-tool : The Proxmark of the USB world. Sniff and analyse High-Speed USB traffic on the protocol level, intercept and manipulate USB-devices in real-time, emulate USB-devices and even build your own real USB-devices directly in the FPA.
Built by GreatScottGadgets, the Cynthion shares the same design-DNA as the HackRF: build a powerful, no-compromise tool that is accessible to everyone. The Cynthion’s feature-set is unmatched by devices 10 times as expensive and bulky.
As with all GreatScottGadget products, the Cynthion has a rich, mature ecosystem of open-source tools that work out of the box.
Whether you’re curious to tinker with USB or you’re a engineer building enterprise hardware – the Cynthion is a must-have tool.
Protocol Analyser
Passively capture low, full and high-speed USB traffic and up to 16 related digital signals simultaneously for analysis.
Reverse Engineer Communications
Full-featured open-source tools for capturing, filtering, visualising and analysing USB-traffic on a protocol level.
MITM USB Devices
Sniff, analyse and manipulate high-speed USB-packets on the wire in real-time via the USBProxy tool.
Build your own USB device
Build custom USB devices rapdily in software via Python, or semi-permanently onto the Cynthion’s FPGA.
Key Features
- Protocol Analyser – Fully-featured low/full/high speed USB Analysis tools via Packetry
- USB Device Designer With Facedancer, build custom USB-devices, either emulated via Python and/or real via the FPGA with LUNA.
- MITM Platform – Real-time manipulation of USB-device communication
- Reverse-Engineering Toolkit – full-stack (software + gateware) tooling for fuzzing, prototyping and emulation of low/full/high-speed USB devices.
- Open Source – 100% open-source software, firmware, gateware and hardware.
- Unibody aluminium case – Robust, sleek annodised aluminium CNC-milled case for complete PCB-protection.
