iPhone Users Spied on Through In-App Ads and Push Notifications

Global phone spy tool Patternz uses device fingerprinting to monitor billions, exploiting vulnerabilities in iOS push notifications.

Both in-app ads and push notifications are being used to identify and spy on iPhone users, according to separate reports.
Apps like Facebook and TikTok are using a vulnerability in the way push notifications are handled by iOS to obtain data for their own use.
A global phone spy tool called Patternz is monitoring billions of people through hundreds of thousands of ordinary apps, including popular ones such as 9gag, Kik, and a series of caller ID apps.
Patternz gathers device fingerprints through smaller ad networks and uses them to trigger surveillance, tracking physical location, hobbies, and family members of people to build billions of profiles.
Security researchers found that iPhone push notifications are being abused to fingerprint your iPhone, sending detailed device information while running quietly in the background.
