https://thehackernews.com/2022/05/lumos-system-can-find-hidden-cameras.html 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 increasingly used to snoop on 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," said Rahul Anand Sharma, Elahe Soltanaghaei, Anthony Rowe, and Vyas Sekar of Carnegie Mellon University in a new paper.
