Why SnoopSnitch? So-called IMSI-Catchers and StingRays act like fake cell phone towers that sit between mobile devices (like smartphones) and the real towers used by cell phone providers.
These fake towers can intercept mobile device communications to track the movement of the person carrying the phone, but also to manage the device remotely.
SnoopSnitch app for Android devices that provides mobile phone owners with information about potential threats in their area.
Note: The app requires root access. Additionally, it only runs on Android 4.1 or later operating systems and requires a Qualcomm chipset. The app has been successfully tested on Moto E and G devices, Sony Xperia Z1, LG G2, Samsung S3 Neo, and Samsung S4. Other devices such as the Nexus 5 or Samsung Galaxy S3 are not currently supported.
You can download the app from Google Play or directly from the project website. You can also download the source code and set up the app in a local development environment.
What is he doing?
The app “collects and analyzes mobile radio data” while in use to warn you about potential threats, such as rogue base stations, user tracking, and over-the-air updates.
After installing the application, you can run tests to detect threats. The tests include placing an outgoing call to a number that is always busy and sending an SMS message to an invalid number.
The app's creators note that service charges may apply, although this is unlikely in the majority of cases. They advise using prepaid SIM cards for your tests, as these provide better options for controlling these charges.
Users of the application can upload their test results to a remote server. The data sent by all users to the server is available to all users of the application. This means that users can access all security events and suspicious activities provided that they have been sent to the server.
A related application is IMSI Catcher Detector , which focuses only on fake base stations.
