Locating Mobile Phones using SS7

You are used to your mobile phone number following you around the globe. But the same functionality that makes you reachable worldwide can also be used to track your whereabouts down to city-level – without you ever knowing about it.

This talk will explain what SS7 features are exploited for locating mobile phones, how the returned information has to be interpreted and what you can (and can't) do against being located that way without having to turn off your phone altogether.
