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 (or a suitable custom ROM with Qualcomm DIAG driver). It requires root priviliges to capture mobile network data.

Disclaimer

The tests include an active part. First, your phone will place outgoing calls to a dedicated number. This number will always be busy and never answer in order to rule out voice charges as best as we can.

Second, your phone will send SMS short messages to an invalid number. In some cases, we saw operators charging for these kind of transactions transactions. Hence, please have an eye on your phone bill when performing active tests using SnoopSnitch. To control for involuntary charges, we strongly advise the use of a dedicated pre-paid SIM card for these tests.

Furthermore, our call server will call your phone and send test SMS during the active test. To avoid unnecessary costs on our side, DO NOT PICK UP OR REJECT AUTOMATIC CALLS FROM OUR SERVER. If you pick up a call or have a mailbox or auto-answer feature configured that picks up the call automatically you may get blacklisted and cannot use our service anymore. Please see our Banned wiki page for details.

Instructions

  1. Make sure you have rooted the phone
  2. Install application from Google Play app store or below
  3. Run the app, execute active tests, upload security events and suspicious activity
