AirSnitch is a novel suite of attack techniques presented at the NDSS Symposium 2026 that undermines security guarantees in WPA2 and WPA3-Enterprise protocols. By exploiting interactions between encryption, switching, and routing layers, attackers can bypass Wi-Fi client isolation to intercept or inject traffic. This discovery shifts the threat model from targeting individual devices to exploiting the underlying wireless infrastructure itself, affecting major operating systems and enterprise-grade hardware.
The research identifies three primary primitives: gateway bouncing, port stealing, and broadcast reflection. These methods allow attackers to manipulate low-level network states, such as MAC address tables, to establish man-in-the-middle (MitM) positions. Crucially, these attacks can span different access points and basic service sets, potentially exposing sensitive credentials and enabling higher-layer exploits like DNS poisoning or rogue AP creation even in properly configured networks.
To mitigate these risks, organizations must move beyond reliance on basic vendor isolation settings. Recommended defenses include implementing robust network segmentation via VLANs, enforcing MAC and IP spoofing prevention, and adopting per-client randomized Group Temporal Keys (GTK). Advanced protections like MACsec (IEEE 802.1AE) provide link-layer encryption that ensures data integrity even if the network perimeter is compromised.
