Wi-Fi attacks have evolved with the introduction of the Nearest Neighbor attack, allowing attackers to compromise distant Wi-Fi networks by exploiting weak security in neighboring organizations.
The Nearest Neighbor attack was first utilized by the Russian APT group Fancy Bear to target organizations in Washington, DC, showcasing the potential threat posed by this technique.
The attack involves steps like identifying targets and neighbors, compromising a weaker neighbor's network, locating a dual-homed device, scanning for the target's Wi-Fi, authenticating to the target's Wi-Fi using stolen credentials, and establishing a foothold within the target's network.
The Nearest Neighbor attack highlights the importance of enforcing MFA for Wi-Fi authentication, securing neighbor networks, monitoring for unusual Wi-Fi connections, and disabling dual-homed devices to defend against such threats.
