A client of mine uses QuickBooks Premier Edition of Manufacturing and Wholesale. It is Registered with 3 seats. Her last good backup of her Windows Server 2008 R2 was on Friday, October 28th at 11:30pm using Windows Server Backup. When she came into work on Monday, October 31st, all the files that were located in the shared S: drive on the server, which is where all the QB related files and work files are located were encrypted with firstname.lastname@example.org. None of the files in the C: drive were encrypted. Even though the S: drive is just a mapping to a portion of the C: drive. Normally I would call this a RANSOMWARE virus. But we were able to use the server without problem. Office, Adobe, and Server all functioned normally as long as I did not try to access the encrypted files. Server Control Panel apps all worked and displayed information without a problem. The only PROBLEM was that there was no RANSOMWARE NOTE! Telling me that my files were encrypted and to get them back, I had to pay a bitware ransom.
I was lucky to be able to copy all the encrypted files to an external hard drive and then restore the backup from October 26th to the original location. It worked fine. QB is able to lookup, process, print, etc, except of course there is no data from October 26 going forward which is ok. We did not want to take a chance of restoring encrypted files. The client was able to restore the 10 invoices missing without incident.
I know that the server and a few PCs ran windows updates over the weekend.
I need to know:
1. what happened?
2. how to prevent this from happening again
