Having an iPhone with you is nice, having a Netflix account also has no problem. But as of now if you are having them both, then there is something to be alarmed, there is a new email scam that is using a fake iTunes bill to fool you into giving the details of your credit card
Like any phishing scheme, these fraudulent emails contain fake bills for products you may not remember having purchased. The emails seem to originate from Apple, and they appear to contain receipts for purchases that you'd normally get in your email – if you have an Apple ID account and buy stuff from Apple's digital stores.
This particular receipt concerns Netflix, and it tries convince you that someone impersonating you has gained access to your Apple account to subscribe to Netflix. Naturally, you'll want to put a stop to it by clicking the available “refund” or “manage subscriptions” links in that email.
You'll then get to a website that looks like Apple's where you have to enter your account and credit card details for the refund. But what really happens is that those details are delivered straight to the scammers. And they'll then put it to good use, meaning that you can expect real warnings from your bank in the near future.
