Definition - What does
Caller ID Spoofing mean?
Caller ID spoofing is a malicious technique where a caller masquerades as someone else by falsifying the number that appears on the recipient's caller ID. Similar to e-mail spoofing by making a email message appear that it comes from one email address, when in reality it has been spoofed and has come from an entirely different one, caller ID spoofing can make a call appear to come from any phone number the caller chooses.
