Re:Xfinity using WiFi signals in your house to detect motion on Monday June 30, 2025 @08:37PM (#44429439)

Is Xfinity licensing Wifi Motion™ from Cognitive Systems?[0]

"WiFi Motion, Cognitive’s Wi-Fi Sensing solution, is an innovative software platform that leverages AI and sophisticated algorithms to transform existing Wi-Fi signals into a motion sensing network."

Another company operating in this space is Origin Wireless. They demonstrated breathing detection with WiFi in 2017[1]. They've since partnered with ISPs to offer a WiFi Sensing "TruShield" home security service.[2]

It underscores how important cybersecurity is in mobile, IoT and Wi-Fi systems. A few critical exploits chained together is all it takes for physical surveillance or bio-sensing[1].

A 2007 NSA hacking toolkit catalog leaked by Snowden[2] shows what state-of-the-art was 18 years ago. Just imagine what a remote attacker can do with today's commercial hardware.
