There’s a really simple way to stop this ransomware from ever gaining control over your network: teach your users to not click on suspicious email links or attachments. This is easily done by enrolling them in new school Security Awareness Training that shows them what to look for, how to remain vigilant while doing their job, and how to keep from becoming the entry point for this and any other phishing-based attack.
