The central issue time and time again is infected documents sent via email to vulnerable operating systems (95%+ windows probably), a little mac, android, ios maybe. So let's block that please. If all these places used chromeos and google docs they would block all these attacks. Add another layer by requring 2 phase auth like yubikeys (not text messages please, too easily hacked).
