WiFi deauthentication attacks and home security
I am NOT a laywer, but I checked how much of what the article describes is illegal in Germany. The answer is just about everything.<p>Installing a doorbell with a camera that looks into the hallway is illegal. You may not record what happens in public spaces on security cameras. And even inside your home, you still have to ask for consent to make an audio recording. Otherwise, this constitutes a crime.<p>Also, sniffing Wifi for data not aimed at you is illegal. The law is quite broad and covers unencrypted data. Sniffing MACs of devices that don&#x27;t communicate with your own network falls under that. Sending deauthenticarion packages using those MACs proves the intent to deliberately obtain that data. Thus might even result in a prison sentence. Deliberately interfering with the operation of a Wifi network may also constitute computer sabotage, but the bar for that is higher.<p>EDIT: I also forgot: creating the program that is intended to specifically interfere with the doorbell is also punishable. This is one of the rare cases where the preparation of a crime constitutes a separate crime in itself. The same goes for the distribution of such tools.
