From the intrusion kill-chain model, the delivery of a “lure” via a text message to a potential victim by pretending to be some trustworthy person or organization in order to trick the victim into revealing sensitive information. Smishing is a portmanteau word made of two other words, the acronym “SMS” and the cyber coinage “Phishing“. It’s a text-message-centric variation of the email-based phishing scams that have been around since the 1990s. The term “Smishing” arose in the late 2000s.
