scam

Identifying legitimate emails from the iTunes Store - http://support.apple.com/HT201679 - lacking in specifics, the next link is better:

Avoid phishing emails, fake 'virus' alerts, phony support calls, and other scams - https://support.apple.com/HT204759

Forward attempts as an attachment to: reportphishing@apple.com

- Apple e-mails address you by your real name, not something like "Dear Customer" , "Dear Client" or an e-mail address.

- Apple e-mails originate from @apple.com or @itunes.com but I think it is possible to spoof a sender address

- Mouse over links to see if they direct to real Apple web sites. Do not click on them as this just tells the spammer they have a working e-mail address in their database.

- Phishing emails may include account suspension or similar threats in order to panic you into clicking on a link without thinking. They may report a fake purchase in order to infuriate you into rashly clicking on a false link to report a problem.

If one actually gets disabled, its owner will be told when they try logging into it instead of through email."

- Apple will not ask for personal information in an e-mail and never for your social security number anywhere.
