Netflix fans are being warned of a new scam which could see strangers hacking into to their accounts and watching movies for free.
The latest warning comes from the security team at Symantec who have witnessed a growing trend in the Netflix black market.
According to the cyber security firm, hackers are using advanced malware attacks to gain access to Netflix user names and passwords.
One malware campaign involves malicious files posing as Netflix software on compromised computers’ desktops.
The files are downloaders that, once executed, open the Netflix home page as a decoy and secretly steals information including bank details from the affected computer.
Phishing attacks which target Netflix users are also becoming more common.
Hackers attempt to steal the login credentials through these campaigns which are then sold for less than £1.
The reason these attacks have been so successful is that Netflix allows multiple users to access one account.
Many people who have been hacked don't ever realise their account is being used by a stranger often based in another country.
On a blog post, Symantec's Lionel Payet explained: "The most common offers are for existing Netflix accounts.
"These accounts either provide a month of viewing or give full access to the premium service.
"In most advertisements for these services, the seller asks the buyer not to change any information on the accounts, such as the password, as it may render them unusable.
"This is because a password change would alert the user who had their account stolen of the compromise."
Luckily, there is a simple way to check what's been going on with your account and every Netflix user should do it right now.
Simply open Netflix on your PC or tablet and head to your name in the top right-hand corner of the screen.
Click this and tap the "Your Account" button.
Next, scroll down to "Viewing Activity" in the "My Profiles" section and you'll see a list of shows that have recently been viewed.
Finally, tap "See recent account access" to view where your Netflix log in has been used.
This menu shows when, where and on what device your account was accessed.
If you suspect foul play then head to your account page, and select the 'Sign out of all devices' option and change your password.
