Email spoofing is a deceptive practice in which a sender falsifies the email header and sender information to make it appear as if the email originated from a different source. This is often done with malicious intent, such as tricking the recipient into revealing sensitive information or downloading harmful attachments. It can also be used for harmless pranks or to hide the true identity of the sender. Email spoofing can be difficult to detect, as the email may look legitimate at first glance, but it is important to always verify the sender’s identity before responding to any suspicious emails.
