>Unlike previous Wi-Fi attacks, AirSnitch exploits core features in Layers 1 and 2 and the failure to bind and synchronize a client across these and higher layers, other nodes, and other network names such as SSIDs (Service Set Identifiers). This cross-layer identity desynchronization is the key driver of AirSnitch attacks.

>The most powerful such attack is a full, bidirectional machine-in-the-middle (MitM) attack, meaning the attacker can view and modify data before it makes its way to the intended recipient. The attacker can be on the same SSID, a separate one, or even a separate network segment tied to the same AP. It works against small Wi-Fi networks in both homes and offices and large networks in enterprises.

I wardrove back in the early 2000s (¡WEP lol!). Spent a few years working in data centers. Now, reasonably paranoid. My personal network does not implement WiFi; my phone is an outgoing landline; tape across laptop cameras, disconnected antenna; stopped using email many years ago...

Technology is so fascinating, but who can secure themselves from all the vulnerabilities that radio EMF presents? Just give me copper/fiber networks, plz.

>the next step is to put [AirSnitch] into historical context and assess how big a threat it poses in the real world. In some respects, it resembles the 2007 PTW attack ... that completely and immediately broke WEP, leaving Wi-Fi users everywhere with no means to protect themselves against nearby adversaries. For now, client isolation is similarly defeated—almost completely and overnight—with no immediate remedy available.

It is hard to disagree with this approach. While I still use WiFi, it is a separate subnet and only whitelisted MACs are allowed to use it. Cameras and microphones are always unplugged when not in use, and my phone runs GrapheneOS. I also removed the hands-free microphone in my car, as well as the cellular modem.

You would like the film The Conversation (1974).
