New AirSnitch Attack Bypasses Wi‑Fi Encryption in Homes and Offices

Security researchers at CyberEdge Labs have disclosed a new wireless attack they call AirSnitch that can circumvent WPA2‑ and WPA3‑based encryption in residential, office, and enterprise environments. The technique exploits a flaw in the handling of the four‑way handshake and group‑key handshake, allowing an adversary to force a client to reinstall its session keys and then capture the handshake traffic needed to derive the encryption keys. By pairing this with a carefully crafted deauthentication burst, the attacker can silently inject themselves into the target network without triggering standard intrusion‑detection alerts.

The attack works by deploying a low‑cost rogue access point that replicates the legitimate SSID and uses a standard 802.11ac adapter to send targeted deauth frames. When the victim reconnects, the malicious AP replays a modified EAPOL message, causing a key reinstallation that mirrors the KRACK methodology but also bypasses the optional 802.11w Management Frame Protection. Through this sequence, the attacker extracts the Pairwise Transient Key (PTK) and the Group Temporal Key (GTK), enabling full decryption of subsequent data frames. The vulnerability, tracked as CVE‑2024‑XXXXX, affects a broad range of devices including consumer routers from Netgear, TP‑Link, and certain enterprise access points from Cisco and Aruba that have not yet applied the latest firmware patches.

The practical impact is severe: any device that associates with the compromised network—including laptops, smartphones, and IoT gadgets—can have its traffic sniffed, exposing plaintext credentials, internal HTTP sessions, and sensitive corporate data. In an enterprise scenario, an attacker who gains a foothold over Wi‑Fi can pivot to the wired network, moving laterally to critical assets. The technique has been demonstrated at distances up to 50 meters in typical office environments, making it a viable option for targeted eavesdropping or data exfiltration.

Mitigation strategies include upgrading to WPA3‑Enterprise with mutual certificate authentication, enabling 802.11w for management‑frame protection, disabling WPS, and applying the latest firmware patches from device vendors. Network segmentation, the use of site‑to‑site VPNs for all Wi‑Fi traffic, and deploying wireless intrusion‑prevention systems that flag rogue APs and anomalous deauthentication patterns are also recommended to detect and block AirSnitch attempts.
