A new email scam is targeting Netflix customers by trying to trick them into handing over their credit card details.

Users are being sent emails that claim to be sent by Netflix, telling the customer that their payment has been declined.

It even has Netflix listed as the name of the sender.

The email says: “We attempted to authorize the Amex card you have on file but were unable to do so. We will automatically attempt to charge your card again within 24-48 hours. Update the expiry date and CVV (card verification value) for your Amex card as soon as possible so you can continue using it with your account.”

The email also contains a prominent “Update Payment” button, which users should not click.

If you do, you’ll be taken to a malicious website that looks like an official Netflix page.

Security firm MailGuard is warning of the scam's dangers.

It said: "Netflix has become a favourite vehicle for email fraudsters. Their large customer base makes them a valuable target for brandjacking; cybercrime that exploits the trademarks of well-known companies to deceive victims.

"This sort of phishing scam allows cybercriminals to harvest victim’s credit card credentials. The phishing page is designed to operate like a legitimate login portal. It asks for card details and password verification, then ejects the scam victim to a real Netflix page to allay suspicion."

Phishing emails are often littered with spelling mistakes or formatting issues, which usually make them easy to spot.

If you think that something isn’t right then do not give out any details.
