Ransomware Attack – How to verify if your devices are fully protected against WannaCry Ransomware

This is an advisory post to help you confirm if your Windows devices are protected from the current ransomware attack, by having the critical Windows patch installed.

We’ve published a knowledge base article that explains in specific steps how to use Patch Management in the RMM Dashboard to check if your devices are protected – please see:

We’ve devised the list of Windows cumulative updates that contain the MS17-010 patch, which is listed below.

To determine if a cumulative update is superseded or not, you can use the Microsoft Update Catalog:

  1. Go to http://www.catalog.update.microsoft.com
  2. Search for one of the patches below (for example KB4015549)
  3. In the list of results, select the relevant OS version
  4. In the popup window, click the Package Details Tab, and view the box entitle ‘This update has been replaced by the following updates:’
  5. Click on any link in that box, to open the more recent patch
  6. Repeat steps 4 and 5 until This update has been replaced by the following updates shows N/A. The patch which shows N/A is the most recent cumulative update.

Following the above process we have established that the critical MS17-010 patch is bundled into these KBs, grouped by OS. If your device has one of these updates, it will have the essential MS17-010 patch as well.
