BLACK HAT 2015: IOT DEVICES CAN BECOME TRANSMITTERS TO STEAL DATA
It’s possible to get a printer and other inexpensive network and Internet of Things devices to transmit radio signals that are detectable far enough away that they could be used to steal data from compromised networks, a researcher tells the Black Hat 2015 conference.
By rapidly turning on and off the outputs from I/O pins on chips within the printer, it’s possible to generate a signal strong enough to pass through a concrete wall and beyond to a receiver, says Ang Cui, a researcher who works at Red Balloon Security and did the research at Columbia University.
The signal was sent down the printer cable connected to the pins that was long enough to serve as an effective antenna. He called the resultant system Funtenna.
