Time was when whaling was done by Captain Ahab and ghosting by Casper. Today the words describe dirty deeds done by scammers. These two terms are part of a dialect of deception that constantly evolves with new schemes or twists on existing ones. Knowledge is power. So to help you boost your fraud prevention know-how, here's a guide to the latest terms in the lexicon of larceny — and the common cons behind them.
