I see there is a recent question about intrusion via USB here.
Would it be similar to do an HID attack via the serial port (UART / RS-232)?
Are there known examples? I can easily physically conduct a nonsecure linux setup that allows root access via the serial port (using hyperterminal or minicom from the attacker) but I don't know more sophisticated ways of intrusion.
I suppose that the os "automatically" would trust a peripheral that is plugged in the serial UART RS-232 port, and the serial port could be used for simple standard i/o and network connections, so do you know if that is the case?
