Researchers from Shanghai Jaio Tong University, University of South Florida and University of Massachusetts at Boston have demonstrated a new technique that can reveal private information by analyzing the radio signal Interference, using just one rogue WiFi hotspot. The WindTalker attack is particularly effective as it does not require any access to the victim’s phone and works with regular mobile phones. The attack needs the hacker to control a rogue WiFi access point to which the target will connect to and collect WiFi signal disturbances. The accuracy of the attack is different based on mobile phone models, and the accuracy could also be improved.
