We lastly have a greater understanding of why units operating iOS 17.5 began resurfacing long-deleted photographs, courtesy of Apple and a few third-party researchers. Whereas Apple launched the iOS 17.5.1 iPhone replace to repair the difficulty earlier this week, attributing it to a “database corruption,” the corporate remained tight-lipped about what was particularly inflicting previous information — together with deleted nudes, in some experiences — to start out showing on units that by no means hosted them.
Elaborating on the difficulty to 9to5Mac, Apple says it was attributable to a corrupt database entry on the machine’s file system, impacting information on the units themselves and never people who had been synced to iCloud. These information might have been carried over from older units when restored from a backup or throughout device-to-device switch.
Apple says it doesn’t have entry to picture or video information on customers’ telephones, and that solely a small variety of individuals have been impacted
One Reddit consumer had beforehand claimed in a now-deleted publish that the iOS 17.5 bug had resurfaced photographs on an iPad that had been wiped and offered to a buddy. Apple, nevertheless, claims this isn’t attainable, telling 9to5Mac that every one information and content material are completely deleted as soon as a tool’s knowledge has been utterly erased. Basically, Apple is claiming this consumer both didn’t comply with the proper machine reset process or is just mendacity for Reddit clout. The corporate stated that solely a small variety of individuals have been impacted by the database problem, and that Apple doesn’t have entry to picture or video information on customers’ telephones.
Safety researchers at Synactiv additionally expanded on the difficulty by reverse-engineering the iOS 17.5.1 replace used to repair it. Yow will discover an in depth rationalization of their full report right here, however in brief, iOS 17.5 added a migration routine liable for scanning and re-importing photographs from the filesystem. The routine was deleted by Apple’s current replace as a result of it brought about previous information to be re-indexed on the native file system and pushed again into picture galleries.
“Based mostly on this code, we are able to say that the photographs that reappeared have been nonetheless mendacity round on the filesystems and that they have been simply discovered by the migration routine added in iOS 17.5,” stated Synacktiv. “Based mostly solely on this evaluation, it isn’t attainable to conclude how the photographs remained on the filesystem within the first place.” The Synacktiv article then directs readers to this touch upon Reddit for a believable rationalization, which incorporates the potential for customers saving pictures to each the File app and Images app and solely deleting the latter.
