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:

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 :)

I was able to confirm the security patch level, however the information could be presented in a nicer way. Also the was some major flickering going on which made it hard to evaluate, still I got the most part out of it, I think.

2015 Samsung tablet only updates for 2 years and patch check showed one missed patch. No Qualcomm chip so no other tools applicable. App description clearly tells you about permissions that you have to agree to and covers all of the negative review issues. Good graphic and allows display of unconfirmed results.
