As a consulting and development organization working with Dynamics SL partners we have noticed an increased number of SL clients being infected with Locky (http://www.idigitaltimes.com/new-locky-ransomware-virus-spreading-alarming-rate-can-malware-be-removed-and-files-512956) and other ransomware viruses.
The most noticeable immediate impact for Dynamics SL users is that the following message starts to appear in a variety of places in SL:
The above message happens because the Locky virus will encrypt the messages.csv file (along with many other files) leaving you with a directory full of encrypted files that look like this:
The virus typically spreads through email attachments, such as word documents with infected macros.
To help limit the spread of the virus to the Dynamics SL program files, you can reduce some of the access rights associated with the SL program files directory. Generally users would need Read, Read & Execute, and List Folder Contents to that directory. They would also need write access to the EventLog folder. You also temporarily need write access to the directory when creating the messages.csv for the first time, or when applying any sort of update or hotfix.
Keep in mind, the typical user will never need full access rights, only the Administrator. So in most cases this is one machine. That machine most likely is the server and would be best to not have Email on it at all.
