Ransomware recovery: are your identity controls clean enough?

TL;DR: Ransomware recovery has to restore clean identity and access paths, not just systems, because attackers often return through exposed secrets, standing privilege, or orphaned accounts, according to Delinea. Clean rebuilds, validated access paths, and post-attack hardening are now the difference between recovery and reinfection.

By the numbers:

• 72% of organisations have experienced or suspect they have experienced a breach of non-human identities, 46% confirmed and 26% suspected.

Questions worth separating out

Q: What breaks when ransomware recovery restores systems but not identity paths?

A: The organisation can bring applications back online while leaving the attacker’s access route intact.

Q: Why do NHIs make ransomware recovery harder than a standard rebuild?

A: NHIs often hold the credentials that let systems communicate, authenticate, and recover at speed.

Q: How do organisations know whether access validation after ransomware is actually working?

A: They should be able to show that every privileged account, secret, and certificate in the restored environment maps back to an approved source and a current business need.

Practitioner guidance

• Inventory every recovery identity before rebuild begins Map service accounts, API keys, certificates, break-glass accounts, and privileged remote access paths before restoring production.
• Bind secret rotation to the eradication phase Rotate high-risk credentials only after malicious footholds are removed and before restored systems are allowed to authenticate again.
• Require access certification after restoration Reconcile all privileged accounts against approved sources, then certify that the restored entitlement set matches least-privilege intent.

Delinea's full blog post covers the operational detail this post intentionally leaves for the source:

• Step-by-step recovery sequencing across detect, contain, eradicate, rebuild, validate, and harden phases.
• Specific Delinea product mappings for secrets, privileged access, lifecycle cleanup, and session auditing during recovery.
• Example recovery checks such as identity inventories, clean secrets snapshots, and validation of privileged paths.
• Operational guidance for time-boxing break-glass access and auditing restoration sessions.
