Did you know?

Phishing is one of the many new computer-related terms that have found their way into the general lexicon over the past decade or so. Its "ph" spelling is influenced by an earlier word for an illicit act: "phreaking." Phreaking involves fraudulently using an electronic device to avoid paying for telephone calls, and its name is suspected of being a shortening of "phone freak." A common phishing scam involves sending emails that appear to come from banks requesting recipients to verify their accounts by typing personal details, such as credit card information, into a website that has been disguised to look like the real thing. Such scams can be thought of as "fishing" for naive recipients.
