Work Email More Dangerous than Personal Email

An analysis over more than a billion emails yielded some interesting stats when comparing work email versus personal email.

The numbers, compiled and reported by Google Research, show that work email is much more prone to hacking attempts, which makes sense.  A compromised work email account can yield a lot more money than a personal account can.

Here are some of the findings:
