The key is to verify that the (daily) backups are clean, as a means of early ransomware detection and preventing good backups from being over-written. Nowhere do I see detailed advice on verifying backup integrity: a) How do you verify that a backup is not encrypted? Can it be automated or would it need a human to detect encrypted data? b) Keep in mind databases, Exchange, Active Directory and data in non-readable formats.
One solution to automating the integrity check is to seed your data with known static data- static files, database records, a mailbox, etc. Only the seed data could be restored and checked against the expected value. But this would be a custom solution, not something off the shelf as far as I know. In fact, seed data could be copied (low-level copy to bypass ransomware hooks into the OS) to another system and checked against expected values even hourly, as an early warning system for ransomware. Has anyone tried this approach?
