About this app

Disclaimer: Patch analysis will work on any phone. However, active network tests and attack monitoring require a compatible* rooted device with Qualcomm chipset.

What. SnoopSnitch analyzes your phone's firmware for installed or missing Android security patches. On compatible* rooted phones, SnoopSnitch can also collect and analyze 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 SS7 attacks.

How. SnoopSnitch allows you to analyze your phone's firmware and provides a detailed report with the patch-status of vulnerabilities (CVEs) by month.

Network security and attack monitoring: To use these features, a rooted device* with a Qualcomm chipset running stock Android 4.1 or higher is required. Custom ROMs are often unsupported as they can lack necessary proprietary drivers. (CyanogenMod seems to work for some users.)

Contribute. SnoopSnitch uses data contributed by users. Patch analysis results and firmware build details are uploaded to our server. This enables further tool improvements and research of the Android patch landscape.

You may also choose to help improve our global network security and threat statistics by uploading your network measurements or security events. SnoopSnitch will ask for confirmation before uploading any such information to our servers. All uploads are encrypted.

Permissions. The app asks for a number of permissions, most of which are only required for network tests and attack monitoring:


License. SnoopSnitch is open-source software released under the GPL version 3. Please visit our project website for source code and further information:


*Compatible phones (when rooted). A list of these devices can be found here:

I Keep getting an error message. I guess my android moto device isn't compatible. It keeps saying something about msm chip.. also this app requires root. With that being said, I guess not all of this app's features will work for my device but this app was very easy to use for me just not compatible unfortunately.

Useless on Google Pixel 7 stock phone. I wanna test a version that runs on non rooted Android 14. Just add opencellid map, the towers to the app and compare a standard non elevated scan for cellids with accurate gps data and you see if there are fake towers around you! Simple as that!

Initially stopped working with Android 11 but uninstall and reinstall fixed that. Currently doesn't find any patches for Android 11, as expected. Previously successfully tracked all Android 10 patches on my Pixel 3a w/o issue. 10/20/21 stopped working on newly installed Android 12; uninstall and reinstall but still fails creating results overview

Hey Michael, we fixed the issue. Now you will see a message, which tells you that there are currently no tests for Android 12 available. This is because it was just released a month ago and the only patches for it were just released a couple of days ago. Creating reliable tests takes time, we are working on it and will release them soon :)
