Wireless jammers cast a dark shadow on IoT security
Autumn DePoe-Hughes captured on video a rather bizarre scene at Manchester Fort Shopping Park this past summer. If car doors were locked, they could not be unlocked. The reverse was true as well. And, annoying car alarms defied any attempt to silence them. DePoe-Hughes told John Leyden of The Register, "Someone else had complete control over our cars for well over half an hour."
Leyden asks Ken Munro, a security researcher at Pen Test Partners, what he thought had happened. "This attack is about jamming the radio signal from the key fob to the car," explains Munro. "Jammers are readily and cheaply available online from overseas sources.... It's also fairly easy to make a jammer from components available at electronics shops."
