Last week, Apple released the iOS 17.5 update, causing old photos to appear on some users’ devices. Users complained, among other things, about the restoration of intimate photos and nudes. The company has already released iOS 17.5.1 patch to fix the problem but how he is writing The reason for Verge’s formation was unknown until yesterday.
According to the latest reports, the problem was caused by corrupt file system database entry on user devices. This issue only affected users’ devices and not files stored in iCloud. Apple has confirmed that photos have been restored on a small number of devices whose owners did not perform the memory clearing procedure correctly. Therefore, undeleted data remained in the file system database from which pictures were restored when synchronized with iCloud.
Synactiv investigated this issue and reverse engineered the iOS 17.5.1 update. It turns out that iOS 17.5 adds a migration routine responsible for scanning and re-importing photos in the file system. Installing the iOS 17.5.1 patch eliminates this procedure, since it is this procedure that re-indexes old files in the local file system and restores deleted photos.
Synactiv stated that photos deleted from the iPhone can continue to be stored on the device until the space they occupy is overwritten with other data. Based on the code reviewed, Synactiv stated that the resulting photos were still stored in file systems and were discovered using the migration procedure added in iOS 17.5.
