To MBT Customers:

If you have the latest patches on your Windows machines, tested backups, and Sophos Intercept X (anti-ransomware product) then you have taken best practices provisions to protect yourself against the new WannaDecrypt0r Ransomware that came out last Friday.  If you are a MBT Total or Proactive Managed Services client then Sophos Intercept X and patches are part of your service with MBT, and again, you are following best practices.

WannaDecrypt0r is particularly nasty ransomware because it spreads across your network.  In addition, it is being propagated multiple ways.  Be sure to use caution and be extra suspicious of email attachments and links.
