In simpler times, the most prevalent scam to be on the lookout for was the so-called "Nigerian Prince" email scam, in which a fraudster would send out an email that persuaded a potential "mark" — often an older adult — to wire them some money in order to trigger the release of a bigger pot of money that was coming the victim's way. More recently, scammers have gotten menacingly creative and even use technology to take advantage of victims.
