The analysis report by Complete Computers begins:
On December 24th 2019, MSLS IT staff was contacted in regards to inaccessible email and server access. Upon inspection, it was determined that two servers were attacked by ransomware which encrypted most of files on both servers (NMRLS and MCLSC). The exact variance of ransomware is named: Ryuk. The attack encrypted most aspects of these two servers, both including but not limited to: work product files (word, excel, word perfect, etc.), email server database files (Outlook emails), the running virtual servers (applications), as well as the local backups that were performed every night. However, there are some aspects of the network that remained unaffected since they were on separate servers and used a different configuration. One of the major servers which remained unaffected by this attack was the Clients Prime Database server which holds all the client information for both programs.
