Is Your TimeSpace Safe? - Time and Position Spoofing Opensourcely

Presented at Black Hat Europe 2015, Unknown date/time (Unknown duration)

We have found a way to produce GPS spoofing with an extremely low cost SDR device and both iPhone and Apple Watch could be affected. (Tech details have already been submitted to Apple Product Security Team. ) The map apps of iOS and Android can be cheated too, and you can even produce an Uber position spoofing, which make LBS apps vulnerable. Futhermore, the time information of smart devices could be easily cheated, since those devices rely heavily on GPS based timing or NTP service (also based on GPS timing). Additionally, we will examine other common positioning methods used by smart devices, such as iBeacon/BLE/WiFi. We will give a demo on how we collect WiFi Access Point SSID data, and then make a fake WiFi environment to cheat WiFi positioning system of Android. In the end, we will also give some suggestions in order to prevent such spoofing.
