Does ransomeware target files based on the extension, or based on the content?
The reason I ask is I am wondering if changing the extension on a file would protect it from ransomeware. I am having to do manual backups of a couple of VM servers because the backup software keeps failing to do so. If I change the VHDX extension to something like SAVE, would ransomeware pass it by? Then I could simply rename the extension if I needed to restore that backup.
Apologies if this is in the wrong forum area.
