Mashable: An unknown number of Apple IDs have apparently been hacked this week, and are being used to buy hundreds of dollars worth of apps in the App Store. It’s not yet clear whether the problem is widespread.
An initial report by blogger Alex Brie highlighted the fact that 40 of the top 50 iPhone apps in the Books category were created by Vietnamese developer “Thuat Nguyen”. A hack of the App Store rankings by a single developer was suspected.
However, Brie later added that numerous Vietnamese book apps were doing suspiciously well in the rankings — Apple responded to the blogger that the issue is being looked into.
