With the introduction of FaceDancer, there has been a surge of interest in USB security. USBProxy is an open framework for the BeagleBone Black to make it simpler for anyone to monitor, inject or modify data carried over a USB connection. While the FaceDancer will allow devices to be written on a host system, we are able to go further and man-in-the-middle connections to existing devices as well. The BeagleBone Black also enables us to operate at USB 2.0 Hi-Speed.
