A Cheap Spying Tool With a High Creepy Factor
Brendan O’Connor is a security researcher. How easy would it be, he recently wondered, to monitor the movement of everyone on the street – not by a government intelligence agency, but by a private citizen with a few hundred dollars to spare?
Mr. O’Connor, 27, bought some plastic boxes and stuffed them with a $25, credit-card size Raspberry Pi Model A computer and a few over-the-counter sensors, including Wi-Fi adapters. He connected each of those boxes to a command and control system, and he built a data visualization system to monitor what the sensors picked up: all the wireless traffic emitted by every nearby wireless device, including smartphones.
I liked this article because; A). He used Rasberry PI computers, and, B). It makes me think how much "offline" data McDonalds, Starbucks, Google and other businesses who offer "FREE WiFi" are collecting about people who do not think they can;t be tracked just because they are not using the device at the moment.
