It’s been almost a year since Apple officially introduced iOS 14.5 with the App Tracking Transparency (ATT) feature, which lets users choose whether they want third-party apps to track them. However, some developers have found new ways to continue tracking iOS users even if they opt out of tracking by third-party apps.
While app tracking transparency (or ATT) works, it still has some vulnerabilities that allow apps to silently collect some data from a user’s device.
Researchers analyzed nine iOS apps that use server-side code to generate user identifiers even when app tracking is disabled. This code is provided by a subsidiary of Alibaba company, it is possible to track this identifier across applications. As a result, advertising companies can still target content to a specific user.
In total, the study compared 1,759 apps before and after ATT was released to iOS users. Although a quarter of these apps claim that they don’t collect any user data, 80% of them still contain at least one tracking library.
