A printer and other inexpensive network and Internet of Things devices can transmit radio signals that are detectable far enough away that they could be used to steal data from compromised networks, a researcher says. Ang Cui says similar exploits could be carried out against other inexpensive devices that have little security. He says he believes his method will work on all UART chips made. Cui’s work is an extension of hacks done earlier, in which devices with other legitimate functions are turned into transmitters. He demonstrated the signal being picked up by a standard handheld radio receiver.”]
