What is Email Spoofing?
Email spoofing is the practice of sending email that pretends to come from a domain, address, or sender identity that is not really the origin of the message.
What it is
Email spoofing is a form of impersonation in email. The sender information is made to look like it belongs to a trusted source even when it does not.
This is commonly used in phishing, fraud, impersonation, and business email compromise attempts.
How it works
Spoofing works by making a message appear to come from a trusted address or domain in the visible sending identity.
Without proper email authentication and receiving-side checks, some systems may treat spoofed messages as more believable than they should.
Why it matters in real life
Email spoofing matters because it is a major part of phishing and impersonation attacks.
Organizations that do not publish strong email authentication records are more exposed to domain impersonation risk.
Common misconceptions
A common misconception is that spoofing always means someone hacked the real mailbox. In many cases, the attacker is only impersonating the sender identity, not actually using the legitimate account.
Another misconception is that spoofing only affects big brands. Smaller organizations and individuals can also be imitated.
