New 'AirSnitch' Attacks Undermine Wi-Fi Encryption

Wi-Fi, a technology integral to modern life with over 48 billion devices shipped, faces new security threats. Despite decades of encryption, recent research has identified fundamental weaknesses at the network stack's lowest levels. These flaws render current encryption incapable of enforcing client isolation, a promised security feature meant to block direct client-to-client communication.

The newly discovered vulnerabilities have been collectively named 'AirSnitch' by the researchers. These attacks successfully undermine client isolation across a broad spectrum of routers. Major brands such as Netgear, D-Link, Ubiquity, and Cisco are affected, as are devices running DD-WRT and OpenWrt firmware. This discovery raises concerns about the security of sensitive data transmitted over Wi-Fi networks.
