Passive Wi-Fi Sniffing Achieves Over 98% Accuracy in Identifying Smartphone Users
A new passive Wi-Fi sniffing attack technique called U-Print has emerged. It can identify specific smartphone users with an astonishing 98.4% accuracy by analyzing the wireless layer metadata of encrypted Wi-Fi traffic (such as packet size, time intervals, and transmission direction) without decrypting the traffic or breaking MAC address randomization defenses. This technology, proposed by … Read more
