Business Email Compromise

Business email compromise (BEC)-also known as email account compromise (EAC)-is one of the most financially damaging online crimes. It exploits the fact that so many of us rely on email to conduct business-both personal and professional.
In a BEC scam, criminals send an email message that appears to come from a known source making a legitimate request, like in these examples:
A vendor your company regularly deals with sends an invoice with an updated mailing address.
A company CEO asks her assistant to purchase dozens of gift cards to send out as employee rewards. She asks for the serial numbers so she can email them out right away.
A homebuyer receives a message from his title company with instructions on how to wire his down payment
