What Is Email Spoofing?

Email spoofing is a type of cyber attack in which an attacker sends emails that appear to be from someone else. The goal of email spoofing is usually to gain access to sensitive information or spread malicious content. It can also be used for phishing attacks, where the attacker attempts to get victims to click on links or open attachments containing malware.

The most common form of email spoofing involves forging the sender’s address so it appears as if the message came from a legitimate source. This technique relies on exploiting weaknesses in mail server configurations and other security measures that allow messages with forged headers to pass through without being detected. Attackers may also use techniques such as domain name system (DNS) poisoning and IP address spoofing in order to make their messages look more authentic. Email providers have implemented various methods for detecting and blocking these types of attacks, but they are still relatively easy for attackers to bypass due to lack of awareness among users about how this type of attack works.
