Serious issue with older Microsoft Windows systems

Updated from 15 May 2019

Earlier this year, Microsoft released information about an issue in older Windows operating systems. Microsoft released software updates for all affected versions.

It has now been reported by security researchers that attackers are actively targeting the older Windows operating systems and installing malicious software.

CERT NZ strongly recommends following the steps in this advisory and updating your operating system as soon as possible. Once you have updated your software, you are no longer at risk.
