Microsoft Exchange Compromised: Action Steps

The recently disclosed ProxyLogon vulnerability is being exploited, installing ransomware called 'DEARCRY' on Microsoft Exchange servers. ARO has worked with clients to install patches to mitigate the risks from these attacks, however the process is more complicated than you would expect, and companies need to be prepared for some challenges. ARO has learned a lot about this new threat in the past weeks that we would like to share in our Security Bulletin (View pdf attachment below for additional information).
