Executive Summary
A multi-site outpatient healthcare group in the United States faced a ransomware incident that disrupted daily clinic operations and threatened access to patient-adjacent documents. Their biggest weakness was not that they had "no backups." It was that they had backups they could not restore quickly and confidently under pressure.
They rebuilt their program around three rules that stayed simple and practical:
- Encrypt data before it leaves the device.
- Keep encryption keys under customer control.
- Make recovery predictable through routine restore testing and a written recovery runbook.
They implemented an encrypted cloud backup approach using RedVault Systems, which encrypts data before sending it to Backblaze B2. The result was not just faster recovery. It was calmer decision-making, reduced pressure to pay ransom, and stronger compliance defensibility through clear documentation.
This case study covers the environment, the rollout, the incident, the recovery process, and the improvements made afterward.
Organization Profile
The organization in this case study was a US outpatient healthcare group operating across multiple locations. It was not a large hospital system with a dedicated security operations center. It was the kind of healthcare provider common across the United States: busy clinics, centralized billing, mixed technical maturity, and a constant need to keep patient flow moving.
Key characteristics:
- Nine clinic sites within one region
- One central administrative office handling billing, HR, and compliance workflows
- A small internal IT team supported by a managed service partner
- Roughly 400 employees with a wide range of technical comfort
- Shared folder workflows used daily for intake, scheduling, and operational documentation
What data mattered most
This incident was not about a single massive database dump. The most painful disruption involved the everyday documents that make outpatient operations work:
- Patient intake packets and front desk forms
- Identity and eligibility documentation used during onboarding
- Insurance and benefits paperwork that supports billing
- Referral attachments and supporting documents
- HR training and policy records
- Operational templates used across clinic sites
Some of these files include sensitive personal information. Many of them are essential to daily work. When they become inaccessible, clinics either slow down or stop.
The Starting Point
Before the project, the group had a patchwork backup approach that grew organically. Different departments protected data in different ways. It was not a deliberate recovery program. It was a collection of habits.
What their backup setup looked like
- A local storage device at each clinic used as a shared drive
- A central file server at headquarters for billing and administrative files
- Manual copies used by certain teams, especially finance and HR
- A cloud sync tool used informally by some staff, not standardized
- Restore testing performed rarely, and usually only when something broke
Why it was risky
Four risks stood out, and all of them mattered during ransomware:
- Inconsistent coverage: Some critical folders were never backed up properly
- Low confidence: Nobody could say with certainty what was protected and how current it was
- Slow recovery: Restores were slow enough that "just rebuild" often felt easier
- Weak defensibility: There was little evidence of disciplined restore testing or recovery readiness
Leadership could not answer basic questions without hand-waving:
- If two clinics lose access to shared folders, how fast can we restore?
- Can we prove backups were tested and working?
- Are backups encrypted, and who controls the keys?
- If ransomware encrypts shared folders, do we have clean versions ready?
This is a common situation. It is not negligence. It is what happens when backup is treated as an IT task rather than a business continuity requirement.
What Changed the Conversation
Two events forced leadership to treat backup and recovery as a board-level risk topic.
A nearby ransomware incident
A nearby clinic group suffered a ransomware event that caused multi-day disruption. Scheduling became chaotic. Patient intake moved to paper. Billing backlog grew fast. Staff morale dropped. The impact was visible and costly.
The leadership team realized something uncomfortable:
Having backups is not the same as being able to recover.
Cyber insurance pressure
During cyber insurance renewal, the insurer asked specific questions about recovery readiness:
- How often do you test restoration?
- Can you recover quickly without paying?
- Are backups protected and encrypted?
- Is your key management disciplined?
- Can you demonstrate what happened in a recovery scenario?
Those questions pushed the group to define a simple goal:
We want to recover quickly without paying, and we want to be able to prove it.
Requirements for the New Program
Instead of shopping by brand, they started with requirements.
Security requirements
- An encrypted cloud backup model where encryption occurs before upload
- Customer-controlled keys, so the provider cannot decrypt stored data
- Integrity verification so restored files can be validated as intact
- Reliable audit logs and evidence trails
- A realistic story that supports HIPAA backup compliance expectations
Operational requirements
- Minimal disruption during rollout
- Simple management for a small IT team
- Scalable across sites without new on-prem hardware builds
- Predictable cost and predictable recovery behavior
- A recovery runbook that works even if the primary admin is unavailable
They also set a decision rule that changed everything:
The backup program must reduce the pressure to pay ransom by making recovery practical.
Why They Selected RedVault
They evaluated multiple approaches. Some were strong on storage. Some were strong on dashboards. Some were strong on general backup features.
The deciding factor was the encryption model and key control.
They wanted a backup approach where:
- Files are encrypted before leaving the local environment
- The encryption keys are controlled by the customer
- Cloud storage is used for durability, but encrypted objects remain unreadable without the passphrase
- Recovery includes integrity verification and predictable restore behavior
They also liked the simplicity of the message they could give leadership:
Our backups are encrypted before upload. We control the keys. Cloud storage alone cannot read our data.
That message matters in healthcare environments because leadership tends to ask a direct question:
If our cloud storage was exposed, would the data be readable?
Their answer became:
Not without our keys.
Implementation Plan
They rolled out the new program in phases to avoid disrupting clinic operations.
Phase 1: Inventory and scope
They created an inventory based on actual workflow dependence, not on IT assumptions.
They asked each clinic:
If this folder disappears for a day, what happens?
That question revealed hidden risks. Some critical files were being stored in places IT did not expect:
- Local workstation folders
- Informal "shared" folders created by staff
- Desktop folders used as working storage
- Ad hoc exports saved to laptops
They standardized backup scope around business impact:
- Front desk and intake folders
- Scheduling templates and operational forms
- Billing and claims support documents
- HR and compliance training records
- Finance and leadership folders
They also agreed on recovery priorities:
- Patient flow first
- Revenue continuity second
- HR and admin third
- Archives last
Phase 2: Encryption-first deployment and key discipline
The security team treated key control as a top-tier operational risk, not a technical detail.
They created a key handling policy that covered:
- Who is allowed to access recovery keys
- Where recovery information is stored
- How emergency access is approved
- How key access is verified on a schedule
- How they avoid a single-person dependency
They implemented a dual-control approach:
Two responsible roles held parts of the access process, so no one person could become a bottleneck or a single point of failure.
They also defined a "lost key" risk statement:
If we lose the key, we lose access to encrypted backups.
That clarity made leadership take key discipline seriously.
Phase 3: Restore testing and recovery runbooks
This was the phase that made the biggest difference during the incident.
They committed to a restore test schedule:
- Monthly restore test for critical clinic folders
- Quarterly recovery simulation for a full clinic site folder set
- Documentation of restoration steps, restoration time, and issues encountered
They created a recovery runbook that included:
- How to choose restore points safely
- How to verify restored folder completeness
- How to re-enable access with minimal risk
- How to coordinate restoration with ongoing containment work
- How to communicate status to clinic leadership in plain language
The goal was not perfection. The goal was repeatability under pressure.
Why Encryption Before Upload Mattered
Healthcare organizations often worry about two things at once:
Keeping operations moving and protecting sensitive information.
Their threat model included:
- Endpoint compromise leading to shared folder encryption
- Credential theft leading to lateral movement
- Attackers attempting to disrupt backup availability
- Extortion attempts involving documents with personal data
Encryption before upload mattered because it reduced dependency on cloud access controls alone. Even if cloud storage access is compromised, encrypted objects remain unreadable without the key.
They also cared about integrity verification for a practical reason:
During recovery, you do not just want files back. You want correct files back.
In clinics, document integrity is operational. A corrupted intake form template or damaged billing export can create cascading mistakes.
The Incident
Six months after the rollout, ransomware hit.
Day 1: Early symptoms
At 6:45 AM, a front desk user reported shared documents would not open. Another clinic called within minutes. Staff noticed file names changing. Some files showed unfamiliar extensions.
Helpdesk reported:
- Shared folders slow or inaccessible
- Repeated login prompts
- Workstations running unusually slow
- Reports of "files not opening" across two sites
The IT lead escalated to security and initiated an incident bridge call.
Containment actions
They moved quickly to prevent spread:
- Isolated affected workstations from the network
- Disabled a suspected compromised user account
- Restricted access to shared folders
- Paused nonessential remote access
- Preserved logs and system images for investigation
Within the first hour, they confirmed ransomware encryption activity affecting two clinic shared folders and one administrative workstation.
Their incident priorities were clear:
Stop spread. Maintain patient flow. Restore critical documents fast.
The Hard Part: Recovery Decisions Under Pressure
Ransomware decisions are rarely purely technical. They are operational, emotional, and time-sensitive.
Leadership wanted immediate answers:
- How bad is it?
- Will we have to cancel appointments?
- Should we pay?
- How long will restoration take?
The IT team did not guess. They used the recovery runbook and their restore testing baselines.
They answered with calm, defensible language:
We have an incident affecting shared folders at two clinics. Containment is underway. We will restore the affected folder sets using tested recovery procedures. We expect partial restoration within the day, with full stabilization following.
That statement reduced panic. It also prevented the common mistake of negotiating too quickly out of fear.
Recovery Execution
They restored in a sequence based on patient impact and business continuity.
Priority 1: Same-day clinic operations
They restored:
- Scheduling and intake folder sets for the two impacted clinics
- Shared templates used by front desk staff
- Operational forms needed for patient processing
During the restore window, clinics switched to manual intake for a short period. Staff used printed templates and temporary workflows to avoid shutting down entirely.
By mid-day, shared folder access for critical intake and scheduling documents was restored for both affected clinics.
Priority 2: Billing and revenue continuity
Next, they restored headquarters billing folders because outpatient revenue continuity depends on fast resumption of billing workflows.
They restored:
- Claims support documents
- Insurance documentation used for eligibility resolution
- Billing exports and processing templates
This prevented a billing backlog from turning into a long-term operational and cash flow problem.
Priority 3: HR and administrative documentation
Finally, they restored HR and policy documentation once patient flow and billing were stable.
Validation and integrity checks
They did not treat restoration as "hit restore and walk away."
They validated restored data using a checklist:
- Spot-check critical files across restored folders
- Validate that expected folder structures and versions were present
- Confirm key templates opened correctly
- Confirm that restored data aligned with known pre-incident baselines
This reduced the risk of restoring corrupted files or reintroducing malicious content.
Outcome
The incident was disruptive, but it did not become an existential crisis.
They achieved key outcomes:
- Restored mission-critical folders within the day, avoiding a multi-day shutdown
- Avoided ransom payment
- Reduced the operational and revenue impact
- Maintained staff confidence through clear communication
- Produced a defensible record of incident response and recovery actions
The biggest success was psychological:
They did not feel trapped.
When organizations have no recovery confidence, they feel forced into negotiation. This group did not.
Compliance and Audit Readiness Impact
The clinic group did not want compliance theatre. They wanted defensibility.
After the incident, they could demonstrate:
- A defined backup program scope aligned to business functions
- A deliberate encryption-first approach with customer-controlled keys
- Restore testing evidence prior to the incident
- A documented incident timeline with containment and recovery steps
- Post-incident corrective actions and program improvements
This improved conversations with:
- Cyber insurance providers
- Leadership governance reviews
- Vendor and partner trust discussions
- Internal compliance and risk management teams
It also strengthened their ability to talk about HIPAA backup compliance in a grounded way:
Not as marketing, but as concrete safeguards and disciplined recovery readiness.
What They Changed After the Incident
They treated the incident as a learning moment and made practical changes quickly.
Stronger endpoint hardening
They tightened local admin privileges, improved endpoint configuration consistency, and reduced risky software execution paths.
This reduced the chance of rapid lateral movement in future attacks.
Key handling maturity upgrades
Customer-controlled keys require discipline. They improved:
- Dual-control recovery passphrase access
- Emergency access procedures
- Quarterly verification drills that confirm key accessibility and restoration readiness
They treated key verification like a fire drill. You want to discover problems in practice, not in a crisis.
Higher-frequency restore tests for high-volume clinics
For their busiest clinics, they increased restore test cadence temporarily until confidence was high and procedures were streamlined.
Third-party access tightening
They reviewed vendor remote access, reduced unnecessary pathways, and strengthened authentication controls for any remote support workflows.
This reduced the chance of credential-based compromise pathways.
