The element of Nohl and Lell’s research that elevates it above the average theoretical threat is the notion that the infection can travel both from computer to USB and vice versa. Any time a USB stick is plugged usb secure into a computer, its firmware could be reprogrammed by malware on that PC, with no easy way for the USB device’s owner to detect it. And likewise, any USB device could silently infect a user’s computer.
A company can manage the installation of important business applications directly onto the secure devices, creating a reusable, portable, completely secure working environment for users that they can run anywhere they go. Some attackers have also targeted electronic devices directly, infecting items such as electronic usb security picture frames and USB drives during production. When users buy the infected products and plug them into their computers, malware is installed on their computers. Firmware updates are installed the first time a device is used, for example, or to update a device so it works on a new operating system.
Torrentz are illegal and it’s unwise to do so unless you are essentially pushing the risk onto someone else, from a ridiculous stupid lawsuit; or just straight malware from a torrent. A portable secure Viewer is automatically usb access control copied to the USB device(s) so users do not have to install any software to view your USB copy protected documents. USB is just, all around bad. Bad for anti-forensics, bad for the kernel and full of exploitable firmware.
