Spoofing is a type of scam in which a criminal disguises an email address, display name, phone number, text message, or website URL to convince a target that they are interacting with a known, trusted source. Spoofing often involves changing just one letter, number, or symbol of the communication so that it looks valid at a quick glance. For example, you could receive an email that appears to be from Netflix using the fake domain name “netffix.com.”
