This information could be combined to form a picture of your movements throughout the day. When you walked by another garbage can, it would note your deviceвЂ™s MAC address and location again. When you walked by one of these garbage cans, your device would send probe requests with its MAC address and the garbage canвЂ™s sniffer would make a note of the MAC address and its location. Then, the garbage cans were networked together. Garbage cans were placed all over the city, and WI-Fi monitoring hardware was installed in them. Take the case of the garbage cans in London. Unless you disable Wi-Fi, this is happening to you.

This is part of the Wi-Fi specification.ДЄs you walk around, the smartphone in your pocket is broadcasting its MAC address for anyone within Wi-Fi range to notice. Smartphones and other devices typically use both passive and active discovery - they passively listen for Wi-Fi access points broadcasting to let nearby devices know theyвЂ™re available, and they actively broadcast requests searching for nearby access points.Дue to the way Wi-Fi was designed, a device searching for Wi-Fi access points includes its MAC address as part of the вЂњprobe requestsвЂќ it broadcasts to nearby WI-Fi access points. Unless you turn Wi-Fi off on your phone before you leave your house, your phone is automatically scanning for available Wi-Fi networks nearby as you move around. Wi-Fi Scanning Broadcasts the MAC Address This applies to laptops and tablets just the same when theyвЂ™re scanning for Wi-Fi networks, too. The problem is how Wi-Fi works and especially how the smartphones we carry around in our pockets work. You can change a deviceвЂ™s MAC address in software, but very few people do this. A network can easily track whether youвЂ™ve connected before and assign settings unique to your device. This lets networks you connect to identify the device.ДЇor example, at home, you could adjust your home routerвЂ™s settings to assign static IP addresses to your devices based on their MAC addresses. This number is designed to be unique to the hardware.
