'This technology turns every router into a potential means for surveillance': researchers warn you can be tracked and identified from Wi-Fi signals
Researchers from the Karlsruhe Institute of Technology have discovered a security vulnerability in Wi-Fi routers that can enable surveillance. By exploiting Beamforming Feedback Information (BFI) signals, individuals can be tracked with high accuracy without needing physical access to the router. This technology raises concerns about privacy, as it allows for identification in public spaces without the need for personal devices.
- ▪Wi-Fi routers using Wi-Fi 5 or later can be hacked to track individuals through their beamforming signals.
- ▪The researchers achieved 99.5% accuracy in identifying individuals based on their walking patterns.
- ▪No physical access to the router is required, making this a significant privacy concern.
