Radar captures subtle cellphone vibrations to eavesdrop on calls from several feet away

Something to look forward to: Researchers at Penn State University have demonstrated a new method of remote surveillance that enables the reconstruction of phone conversations using the subtle vibrations generated by a cellphone's earpiece. This technique, known as wireless tapping, uses millimeter wave radar sensors to detect and interpret these minute vibrations from distances of up to ten feet.

AI can see what's on your screen by reading HDMI electromagnetic radiation

Researchers say the technique is already being used in the wild
Shiver me timbers: Security researchers have demonstrated that it's possible to spy on what's visible on your screen by intercepting electromagnetic radiation from video cables with great accuracy, thanks to artificial intelligence. The team from Uruguay's University of the Republic says their AI-powered cable-tapping method is good enough that these attacks are likely already happening.
