In a new development in the world of scam artists, the more impatient ones have recently been turning to couriers to steal money from victims of fraud faster. Couriers usually are dressed in plain clothes and arrive in normal-looking vehicles. In some cases, you may be instructed to meet the courier away from the victim's home in places like public parking lots.

Better Business Bureau Investigator Don O'Brien says in one recent case, an elderly man nearly lost a lot of money.

Be wary of random calls or messages in which the person on the other end instructs you to download unfamiliar apps to your phone or go to unfamiliar websites on a computer. Communication between the scammer and the victim is frequent. If you are told to keep something a secret, something is wrong.
