Port 3389 Exploit: Prevent another WannaCry

16 May 2019

On Patch Tuesday (14 May 2019) Microsoft offered an RDP patch for legacy Windows and outlined the details here: https://blogs.technet.microsoft.com/msrc/2019/05/14/prevent-a-worm-by-updating-remote-desktop-services-cve-2019-0708/ The most immediate steps your organization should pursue are the following: Disable port 3389 from being publicly visible as it is only a matter of days, or perhaps hours, before the patch is reverse-engineered into a wormable exploit. To test if you are publicly visible, check out grc.com/shieldsup to show not just RDP but any other ports you may be exposing to the public Internet.

This invasion of individual privacy is definitely a problem we want to allow our users to mitigate.
