Cybercriminals are targeting Netflix users with several scams you need to watch out for. Some of these scams claim you need to update your payment information, and others try to trick you into downloading software for a cheaper version of Netflix. Do not fall victim for any of these tricks.
Only download Netflix software from the Netflix website or official app stores, and always go to these websites yourself instead of clicking on a link in an email. Also, if you receive an email that looks like it is from Netflix, and claim you need to update payment information, do not click on any links or open any attachments. Go to the Netflix website yourself using your browser and check your account. Call their customer service if you want to be 100% sure, using the 800 number you found on their website.
