This is how hackers can steal millions from your company with just one email

Imagine a corporate bookkeeper gets an email from his CEO that says, “Hey, I need the W-2s for everybody in the company.” The diligent bookkeeper gathers the requested tax documents and sends them off to the executive. But the initial email wasn’t really penned by the CEO—it was written by a crook who broke into the executive’s email account. The goal: to carry out a new type of cybercrime called “business email compromise” or BEC, which hackers have used to try to steal billions of dollars in recent years.
