We confirm that iOS 16 does communicate with Apple services outside an active VPN tunnel. Worse, it leaks DNS requests. #Apple services that escape the VPN connection include Health, Maps, Wallet.
We used @ProtonVPN and #Wireshark. Details in the video:
You can easily monitor the network traffic of any device using this simple method. You don't need a custom router for that. You just need a Mac and #Wireshark, and enjoy ✌️
I know what you're asking yourself and the answer is YES. #Android communicates with #Google services outside an active VPN connection, even with the options "Always-on" and "Block Connections without VPN."
I used a #Pixel phone running #Android13, its IP is 192.168.2.14 👇
We prepared this video to illustrate why access to the accelerometer should get a permission in iOS. Unrestricted access to accelerometer data can breach user privacy. We used Facebook as an example in the video.
It's amazing what algorithms can extract from accelerometer data:
- Detect if you're walking, sitting, cycling.. etc
- Count your steps
- Figure your heart rate
- Find your precise location
- Analyze sound vibrations of your phone speaker and infer what you're listening to
The iPhone is equipped with a very accurate accelerometer. It helps algorithms achieve their goals with high accuracy.
Good news: iOS only allows apps to access the accelerometer when apps are active in the foreground
