🌐🇩🇪🇪🇺❓‼️WiFi signals can identify people even without a network connection – German scientists warn. Scientists from the Karlsruhe Institute of Technology (KIT) in Germany have shown that regular WiFi networks can be used to identify specific people based on passive recording of WiFi signals alone, even if the person does not have any WiFi devices with them or has them turned off. This technology uses the reflections of radio waves from the human body and artificial intelligence to create a unique “fingerprint” of movement and figure. According to a study published in October 2025 at the ACM SIGSAC Conference on Computer and Communications Security (CCS '25), the method achieved almost 100% accuracy in identifying people in tests with 197 volunteers. Identification takes place within a few seconds after the appropriate machine learning model is trained. The method does not require any special hardware – a standard WiFi router and access to signals in the surrounding area are enough. The key element is the use of beamforming feedback information (BFI) – unencrypted feedback signals that devices connected to a WiFi network regularly send to the router to optimize transmission. These signals can be captured by a third party within range and allow for the reconstruction of an image of the surroundings, including the people present, similar to a camera, but based on radio waves instead of light. Unlike older methods based on channel state information (CSI), this technique does not use active measurement, but passively monitors existing network communications. KIT researchers, including Professor Thorsten Strufe from the KASTEL Institute and PhD student Julian Todt, explicitly warn of the risks of misuse. Any ordinary router can become a passive surveillance tool – for example in cafes, offices, public spaces or private homes‼️ Identification is possible even through walls and does not require the person being monitored to have an active device; the presence of other WiFi devices in the vicinity is sufficient. The European Commission drew attention to this study via its official @DigitalEU account on the X network (formerly Twitter). In a February 2026 post, she said: “WiFi networks can identify you – even when you’re not connected to them. Using only antennas and artificial intelligence algorithms, German researchers have reconstructed the shapes of people in a room. They warn that the technology could be misused as a tool for surveillance.” The topic has sparked a wide-ranging debate about privacy in the era of widespread WiFi and IoT devices. Researchers are calling for new regulatory measures, encryption of return signals and other technical safeguards to prevent the technology from being used on a mass scale for unauthorized surveillance.
