It appears that the corrupt apps infiltrating Apple’s App Store was due to the company’s FairPlay Digital Rights Management (DRM).
As we reported yesterday apps downloaded from the App Store were crashing on launch, a widespread corruption issue that was plaguing app updates submitted to the Store.
Apple initially notified some developers directly, advising that a fix was in the works for the corrupted Mac and iOS apps. In a statement Apple said it is aware of the bug and is working on a solution.
On Apple’s developer forums, the company initially released a statement, “According to our developer sources, Apple has now responded to numerous complaints in its Developer Forums with a brief statement posted by username “iTunesConnect. ”We are aware of the issue related to apps crashing after update. We are currently working on resolving the issue.”
The corruption had caused headaches for a number of developers as it had prompted a huge number of one-star reviews being sent in from disgruntled users because of an issue completely out of their control.
The issue lasted over 24 hours and caused a downward trend in the review scores of apps that had been affected. These represent the users which have downloaded the update from the server disrupted by the corruption. Not all servers were affected, so there werr still some five-star ratings coming in, reported The Next Web.
Apple then issued another official statement explaining what and why the issue occurred, “We had a temporary issue that began yesterday with a server that generated DRM code for some apps being downloaded. The issue has been rectified and we don’t expect it to occur again,” Apple said in a statement to AllThingsD.
Only a small number of users were affected, however all users are advised to perform a back up, delete the corrupt version and re-install the app.
Marco Arment, developer of Instapaper listed the affected apps on his blog.
