In a slight twist on the august pursuit of warwalking, [Mehdi] took a Raspberry Pi armed with a GPS, WiFi, and a Bluetooth sniffer around Bordeaux with him for six months and logged all the data he could find. The result isn’t entirely surprising, but it’s still a little bit creepy.
If your WiFi sends out probe requests for its home access points, [Mehdi] logged it. If your Bluetooth devices leak information about what they are, [Mehdi] logged it. In the end, he got nearly 30,000 WiFis logged, including 120,000 probes. Each reading is timestamped and geolocated, and [Mehdi] presents a few of the results from querying the resulting database.

[Michael] was playing with his ESP8266. Occasionally he would notice a WiFi access point come up with, what he described as, “a nasty name”. Perhaps curious about the kind of person who would have this sort of access point, or furious about the tarnishing of his formerly pure airspace, he decided to see if he could locate the router in question.
Sure enough, the person with the questionable WiFi access point shows up on the map.
The term ‘warwalking’ isn’t used very often, but the Ekahau HeatMapper adds a new tool to the pod bound hacker’s arsenal. The tool maps out wireless access points as well as their signal strength within a facility. A test of the HeatMapper on a map made with AutoDesk Dragonfly accurately determined the location of a router within 3 feet and helped tune the angle it needed to be at for maximum range. Ekahau made a fantastically cheesy promotional video for their product, which is viewable after the jump. The program is free of charge, but unfortunately only runs on windows, so mac and *nix users are out of luck, though it might run under wine.
