I captured 72 hours of idle Android packets behind pfSense

A researcher captured 72 hours of idle Android packets behind a pfSense firewall, revealing a significant amount of data transmission from Google services, including Google Play Store and Google Play Services, even when the device is idle. The researcher found that these packets were not related to any user interaction, but were still being transmitted to Google's servers. The data transmission includes details about the device's hardware and software, as well as the location and language settings. The researcher suggests that this is a result of the way Google's services are designed to collect data, even when the user is not actively using the app.
