Spoofing
Forging email headers to make a message appear to come from a different sender than the actual source.
Definition
Email spoofing is forging email headers to make a message appear to come from someone other than the actual sender. Spoofing is commonly used in phishing attacks and spam campaigns. Email authentication protocols (SPF, DKIM, DMARC) are designed to detect and prevent spoofing by verifying sender identity.
