Key impact: Any passive eavesdropper can turn any modern WLAN into a person-identification system without special hardware or user interaction.

This research highlights urgent privacy risks as WiFi sensing becomes standardized. We're calling for protective measures in upcoming WiFi standards.

🎉 Happy to share that Julian presents our paper showing how beamforming feedback information - openly broadcast by WiFi devices and accessible to any passive network sniffer - can identify individuals with near-perfect accuracy, even those who don't carry any devices, at ACM CCS in Taipei this week!
Title of our paper at CCS 2025, demonstrating an attack using beamforming feedback information to identify individuals walking through a WLAN

It is Wednesday morning and I need $15,000 to fall from the sky so that a group of extremely high-risk activists can continue to get anti-doxxing protection and data-deletion services.
