Tool Reveals iPad and iPhone User Locations 36
mask.of.sanity writes "A researcher has found that Apple user locations can be potentially determined by tapping into Apple Maps and he has created a Python tool to make the process easier. iSniff GPS accesses Apple's database of wireless access points, which is collected by iPhones and iPads that have GPS and Wi-Fi location services enabled. Apple uses this crowd-sourced data to run its location services; however, the location database is not meant to be public. You can download the tool via Giuthub."

And this is why your iDevice should never be set to automatically join wifi networks.
Actually, NO device should be configured to automatically join wifi networks.
(For those who didn't read the docs that go with the software, this relies upon running an access point with no DHCP, which is what forces the iDevice to send ARPs for the last DHCP server it used).
Also, this means that if you want to "hide" your home network, don't run DHCP on your WiFi router, use another device.
