Email spoofing is when the sender alters email header fields to appear as if they are from a different source. This is often done for fraudulent reasons, such as obtaining personal information or spreading viruses. Simple Mail Transfer Protocol (SMTP) is commonly used for email, but it is not secure and does not provide authentication. It can be difficult to detect email spoofing, but clues like writing style and links can help.
Email spoofing is the act of altering certain email header fields to make them appear to come from a different sender. While this act is sometimes done for legitimate reasons, it is more frequently done for fraudulent purposes. Considered a form of spam, spoofed emails are typically sent to obtain sensitive or personal information from the person receiving the emails.
Simple Mail Transfer Protocol (SMTP) is a common protocol for sending email across various Internet protocol networks. While SMTP is standard, it is not very secure, as it does not provide email authentication. Therefore, email spoofing is believed to be a simple process. It is often done by changing the name or email address that appears in the header section of the email to make it appear as if it is from an authoritative source. The more complex forms usually consist of the spammer manipulating certain information and sending emails via an open relay SMTP server.
A spammer can use email spoofing for several reasons. In many cases, fraudulent emails are sent to obtain personal information, such as passwords or credit card numbers. They can also contain harmful material, such as viruses. Phishing emails, or those sent to obtain personal information, may state that the user needs to change their password on a particular website or may indicate that the user’s bank urgently requires an update of personal information, such as card credit or check account routing numbers. Malicious email spoofs can contain viruses that can be destructive to your computer or help the spammer acquire information about your email habits, sensitive documents, or email contacts.
While it can be difficult to detect email spoofing in some cases, some clues can often indicate that the email you received was spoofed. For example, it’s important to keep an eye on writing style, as most businesses and websites have a standard way of relating to their users. Hovering over any link in the text is another way to see if the email is legitimate. Dummy emails will often contain a string of numbers and letters that show no information about the website the email claims to be from. You may also need to search for some header fields, such as Return-Path or From fields.
