IoT Security Research
Recently I had a chance to look at a number of intruder alarm systems sold via Amazon and eBay. These devices sell for up to £150, and a number are best sellers
As discussed in my last post, RF frequency communication can be captured relatively easily, using a software-defined radio (SDR). All four devices use 433MHz RF to communicate between the sensors and the base station. Capturing transmissions from each device proved extremely simple; the following shows the result of triggering one of the door sensors included with the Kerui alarm:
