SnoopSnitch

SnoopSnitch is an Android app that collects and analyzes mobile radio data to make you aware of your mobile network security and to warn you about threats like fake base stations (IMSI catchers), user tracking and over-the-air updates. With SnoopSnitch you can use the data collected in the GSM Security Map at gsmmap.org and contribute your own data to GSM Map.

This application currently only works on Android phones with a Qualcomm chipset and a stock Android ROM 4.1 or higher (or a suitable custom ROM with Qualcomm DIAG driver). It requires root priviliges to capture mobile network data.

SnoopSnitch uses data contributed by other users. By choosing to upload your measurements or security events, you can improve this data and support future research. SnoopSnitch will ask for confirmation whenever any information is uploaded to our servers. All uploads are encrypted.
