Hackers claim to have broken into Apple's systems before posting a list of names and password hashes online.
The FT, in a story careful to make a number of caveats, attributes the hack on what would appears to be Apple's business intelligence unit on infamous and recently disbanded prankster hackers LulzSec. None of this has been confirmed and Apple is yet to say anything about the supposed hack.
Both LulzSec and Anonymous have targeted security consultancies and multinationals such as Sony over recent weeks, partly out of mischief and partly to expose poor security practices. The Apple attack might be taken to fit with that broad aim.
Anonymous linked to the supposed Apple data dump before, saying that "Apple could be target, too. But don't worry, we are busy elsewhere".
The whole situation is confusingly sketchy and all we can say for sure is that internal users of Apple's survey site ought to change their password, especially if they used login credentials likely to be exposed by a brute-force dictionary attack on the exposed password hashes.
The hack is limited to a problem with the survey site, so iTunes users, for example, should rest easy that their login credentials have not been exposed. ®
