How to Test Ransomware Recovery Without Reinfecting Your Environment

Summary: This vendor-authored article argues that a successful backup job does not guarantee successful ransomware recovery, because attackers compromise identity systems, alter configurations, and create persistence mechanisms that survive restoration, so a clean backup can still reintroduce dormant malware or broken dependencies. It lists common failure points in MSP recovery testing, including testing in partially connected environments that enable lateral movement, synthetic tests that only encrypt files, and restoring immutable backups that contain dormant malware, and it cites ISO 27001 and NIS 2 as frameworks requiring tested and audited recovery capabilities.
What's compelling: Under NIS 2, management accountability includes demonstrating that recovery processes are tested and effective, and recovery readiness reports are treated as evidence for regulators and cyber insurance providers. Immutability prevents deletion or alteration of a backup but does not establish that the data inside it is clean.
