writes "Back on November 28, 2010, somebody started a thread on Apple’s support forums about someone spending more than $50 of his iTunes Store credit on iPhone apps. That discussion thread has since swelled to more than 45 pages, with nearly 700 posts. Someone—or some group of someones—seems to be able to spend iTunes gift card credit without permission, buying apps that users don’t want. And whoever’s doing the hacking seems pretty good at it: Hundreds of users have seen their iTunes credit stolen, and the hack shows no signs of slowing, ten months after it was first reported.
Apple has refunded certain accounts, but not in all cases.
Apple suggests that the hack stems from weak, easily guessable passwords, and/or phishing attacks where customers are fooled into entering their passwords into hackers' forms."Link to Original Source
