Spoofing e-mails are messages that look like they are from a legitimate sender, but the actual sender is concealed. A “spoofer” will usually spoof the “from” header. They are sometimes an attempt to get information that could lead to identity theft or other fraud. Additionally, they could download a virus, worm, other malicious program, or even spyware or web beacons onto your computer. In these cases, they are known as phishing e-mails.
