   A group of academics has devised a system that can be used on a phone
   or a laptop to identify and locate Wi-Fi-connected hidden IoT devices
   in unfamiliar physical spaces.

   With hidden cameras
   being [2]increasingly [3]used to [4]snoop on [5]individuals in hotel
   rooms and Airbnbs, the goal is to be able to pinpoint such rogue
   devices without much of a hassle.

   The system, dubbed Lumos, is designed with this intent in mind and to
   "visualize their presence using an augmented reality
   interface," [6]said Rahul Anand Sharma, Elahe Soltanaghaei, Anthony
   Rowe, and Vyas Sekar of Carnegie Mellon University in a new paper.
