When Wi-Fi Encryption Fails: Protecting Your Enterprise from Air Snitch Attacks

Summary: Unit 42 researchers presented AirSnitch at the NDSS Symposium 2026, a set of attack techniques that exploit interactions between Wi-Fi encryption, switching and routing layers to bypass client isolation and break WPA2 and WPA3-Enterprise protections across devices from several major vendors and on Android, macOS, iOS, Windows and Ubuntu Linux. The attacks include Port Stealing, which exploits Wi-Fi design errors the researchers say are difficult or impossible to patch within existing standards, and Gateway Bouncing, which relies on organization-specific configurations, and the researchers are releasing the findings publicly rather than through coordinated disclosure.

Why it matters: The researchers state that some AirSnitch flaws cannot be patched within the existing protocol standards and recommend treating these protocols as inherently insecure, so a properly configured WPA2/3-Enterprise network no longer stands as the perimeter you have assumed it to be.
