Microsoft operates an online store in India which was managed by a third party company.
The store was hacked earlier this month and the company has just revealed to the users of this service that the hackers might have gotten their hands on the credit card details of the users.
The company is advising users to keep an eye on their credit card statements. We assume that the users would have to apply for a replacement card from their respective banks.
Microsoft further said that they are operating a helpline where you can call to get any doubts cleared.
The company has not revealed any plans to offer protection services to the affected users. The store remains down.
