Which term describes email spoofing?

The term that accurately describes email spoofing is altering email headers to pretend to be a different sender. Email spoofing involves the manipulation of the "From" address or other parts of the email header to make it appear as though the email is coming from a trusted source when it is not. This technique is commonly used in phishing attacks, where the goal is to deceive the recipient into believing the email is legitimate so they may provide sensitive information or perform an action that could compromise their security.

The concept of spoofing hinges on the ability to misrepresent the sender, which is achieved through the modification of the email's header information. It is essential to be aware of this tactic as it can lead to unauthorized access to personal and professional information, making vigilant email practices critical for cybersecurity.
