Wifi signals don't need root privileges. The radio handles that level at userland privileges. The data on USB's or over cellular or wifi isn't the issue. The built-in radios need root privileges because they have microcontrollers in there. Those were installed at the factory and are known clean, and there's no firmware path that can be reached by the data traveling over it.The issue with USB sticks is that the firmware that controls how they work DOES have root privileges to identify it and tell the kernel how the structures are laid out. Since the USB and SD standards will allow these devices to perform other duties (such as keyboard, mouse, any other number of things) then they must be able to talk directly to the CPU bus. That's where the exploits have been, modifying the firmware of the devices themselves which can then put any instructions some malicious type wants directly into the CPU with root privileges. We consider that pretty dangerous. |
