"Shark Tank" star Barbara Corcoran is missing nearly $400,000 Wednesday morning after her office was victimized by email scammers who used a tiny typo to gain the upper hand. The scam started last week when an email chain was forwarded to Barbara's bookkeeper, a woman named Christine. Folks on Barbara's team tell us the email appeared to have been sent from Barbara's executive assistant, Emily ... and it informed Christine she had the green light to pay $388,700.11 to a company called FFH Concept GmbH in Germany. The problem is that email didn't really come from Emily.
