What is Email Spoofing? Email spoofing is the fabrication of an email header in the hopes of duping the recipient into thinking the email originated from someone or somewhere other than the intended source. Because core email protocols do not have a built-in method of AUTHENTICATION, it is commonplace for spam and phishing emails to USE said spoofing to TRICK the recipient into trusting the origin of the message. The ultimate goal of email spoofing is to get recipients to open, and possibly even respond to, a solicitation. Although the spoofed messages are usually just a nuisance requiring little action besides removal, the more malicious varieties can cause significant problems, and sometimes pose a real security threat. As an example, a spoofed email may PURPORT to be from a well-known retail business, asking the recipient to provide personal information like a password or credit card number. The fake email might even ask the recipient to click on a link offering a limited time deal, which is actually just a link to download and install MALWARE on the recipient's device.Explanation:Hope it helps you!
