Like most modern lingo, the meaning of spoofing started off initially as something completely unrelated to electronic mail. What it really meant was duping a person via the telephone over calls. This could be anything from a harmless prank call to a serious fraud call where people pretend to be your finance representative or your bank officer asking to confirm your details via phone over a transaction issue or something else. If you answer these calls and actually give in the details, you’ll probably be another victim to this chain of frauds.
