As a result, the number of vulnerable systems has fallen by 45%, according to an NSC spokesperson.

The one-click Microsoft tool was created to protect against cyberattacks and to scan systems for compromises and fix them. It was developed after a massive hack affecting an estimated tens of thousands of users of servers running Microsoft’s Exchange email program.
