From the BBC news site:
Tens of thousands of fraudulent iTunes accounts are for sale on a major Chinese website, it has been revealed.
About 50,000 accounts linked to stolen credit cards are listed on auction site TaoBao, the country's equivalent of eBay.
Buyers are promised temporary access to unlimited downloads from the service for as little as 1 yuan (10p) a time.
Apple, which recently stepped up iTunes' security after a series of break-ins, declined to comment.
However the company has warned users in recent months to safeguard their personal details.
It is no secret that we are very much leery of leaving any credit card information in any online merchant’s site if we can help it.
The question around iTunes account security has been one that we have been keeping an eye on for quite some time now.
So, when working with client’s iTunes set ups, or other online merchant activities we suggest that they never save their credit card information and if possible purchase gift cards to use with the online service.
