The FBI announced 74 arrests across seven countries in a major email fraud bust on Monday. 

The alleged email scammers, who spread across seven countries, would target mid-sized businesses, looking to trick employees who had access to the company's finances. These "cyber-enabled financial fraud" originated in Nigeria -- the same source of the notorious Nigerian prince email scams --  fool victims into believing they're sending money to business partners, while they're really giving thousands of dollars away to thieves.
