Screenshot summary

Meituan App a technical engineer said in an interview with the media, the emergence of this situation because this software after unilateral read system operation log, has carried on the selective display, after the test, in the relevant permissions to open and App background is still in the active state, most mainstream App will be detected the software frequently read user information, And the results were highly similar.

One iOS App developer analyzed that this activity log is not used to determine whether an App is stealing information.

For example, if a user grants an App the right to "always read the contents of an album" and the App is still active in the background, the system will "alert" these active apps when it detects that a user has added a new photo.

However, from the perspective of users, if they do not use the App in the foreground, it means that they have been "closed". As a result, when such records are seen, it creates the illusion that someone is secretly stealing information.

Meituan should be in the same situation, the developers say. If the App is not completely closed after the user grants permission, and the geographical location keeps changing, the iOS system will constantly evoke meituan App, providing convenience for users to order food at any time.

According to the engineer of Meituan, the user who first posted the microblog refused to provide more information. Therefore, it is impossible to confirm the status of the user when the data was intercepted, but according to the system analysis, the user should have moved over a large range in the location of meituan App.

According to public reports, the software that reads iOS 15 system logs is developed by overseas personnel. The engineer said that the security and confidentiality of the software has not been tested, and it is recommended that everyone download with caution.
