Almost One Million Vulnerable to BlueKeep Vuln (CVE-2019-0708)

A lot of others are Windows machines, sometimes vulnerable and sometimes not, but for some reason return errors sometimes. Thus, out of 7.6-million devices that respond to port 3389, we find 3.5-million that reliably talk the Remote Desktop protocol, of which 0.9-million are vulnerable, and the rest are not. However, others are likely ISPs with Windows machines moving around from one IP address to another, so that continued rescans are going to get distorted results rather than cleaning up the previous results.
