PrivacyBreacher

PrivacyBreacher is an Android app built as a proof of concept for a research article describing the privacy issues in Android. This app can access the following information from your phone without requesting any permissions:

  1. Figure out at what time your phone screen turned on/off.
  2. Figure out at what time you plugged in or removed your phone charger and wired headphones.
  3. Figure out at what time you switched on/off your phone (i.e., it captures the device uptime and ACTION_SHUTDOWN broadcasts).
  4. Access most of your device related information like your phone model, manufacturer etc.
  5. Keep track of your WiFi/Mobile data usage.
  6. Get a list of all the apps installed on your phone.
  7. Construct a 3D visualization of your body movements.

This app supports Android Pie (Android 9, API 28) or later versions.

Edit: Some issues mentioned here might have been fixed in Android R, API 30 (the latest version of Android). Check out this issue for more. We'll release an update for that soon. Currently, the privacy issues mentioned here are valid till Android Q (API 29).
