I have an odd case. It appears to me that I have signs of a encryption type virus, but there is no ransom note to be found anywhere.


Symptoms - 2 shared drives on a server where all file modified dates are changed to yesterday and are all unable to be opened. At the same time, other shared drives on this server have no issues whatsoever. Also, there are no hardware/software problems that I can detect on the machine.

How do you know the files are encrypted?


What errors are you seeing when you try to access the files?

Please download ID Tool by Nathan Scott and save to the Desktop of the infected computer.
-- This is a small utility that checks for evidence of crypto malware, then helps identify what kind of encryption infection you are dealing with.
  • Extract (unzip) the file...then double-click on IDTool.exe to run the tool.
  • Wait for it to configure, scan and load.
  • Click the "Generate Text Friendly Report for Forums" button.
  • A box will appear with a report as shown above.
  • Copy and paste the contents of that report in your next reply.
Note: ID Tool requires .NET Framework 4.0 to be installed in order to work. If ID Tool appears with no information when run, it means nothing was detected. To double-check and confirm no evidence of infection, just select the "Rescan Computer and Generate new Report" button. If once again there is no information, that confirms nothing was detected.
