Email spoofing refers to a sender address that is forged to make it look as if it came from someone else.
This is a common technique used by phishing attacks, spam, and malware to make their emails appear to be coming from legitimate sources, such as governmental authorities, insurance companies, and banks. They will frequently contain requests for confidential information, such as social security numbers or banking details, and requests to reset passwords.
