For privacy researchers, this thread is interesting. iOS allow apps to make network requests after push notifications.

Instagram (and others) appear to be using this to profile devices, eg retrieve device uptime without their customer opening Instagram.

This one probably needs more eyes on it. https://mastodon.social/@mysk/115204746326765802

A GET request sent by Instagram when the notification was shown on screen.

Attached: 2 images 🤯 Instagram is testing new iOS push notifications that include a profile photo. Each time the notification is shown on your screen, it triggers a GET request to fetch that image, letting Meta track every on-screen impression. The app still misuses push notifications to send detailed device analytics about the device (uptime, battery, volume, locale, timezone, memory, CPU, etc.) #privacy #infosec #privacymatters #Apple #iOS #meta More 👇🧵
