Find me on:


A major ransomware attack is currently spreading worldwide, impacting over 100 countries. This attack, called “WannaCry” affects Microsoft Windows systems by exploiting a vulnerability called EternalBlue. Microsoft provided a patch for this in March and you can learn more about it here at Microsoft's blog.

Essentially, you are susceptible to this attack if…

  • You are running an out of date version of Windows operating system like XP, Vista and/or Server 2003
  • You are running any Windows operating system that has not been patched/updated since 03/14/2017

There has been a high volume of reports of this ransomware attack affecting Microsoft Windows systems globally. It also anticpated the WannaCry ransomware will begin to make an appearance in the US early this week and your business should be prepared. If you haven’t already, patch your Windows systems to the most up-to-date version. Microsoft provided an update, however, it needs to be uploaded.
