Bluekeep vulnerability (CVE-2019-1162) has been the talk of the town since it’s emerge on the large scale and Microsoft has been aware of the fact of the worm that can create the risk of the large scale outbreak due to the ability to replicate and propagate like Conficker and WannaCry.
Microsoft has reset the clock in that race, revealing a collection of new RDP vulnerabilities, two of which could also result in the same sort of global worm and this time in newer versions of Windows.
It has been highly recommended to install the latest Windows Update which includes the patch for this vulnerability.
