A US regional health system, 6 hospitals, 8,000 staff, 200,000 patient encounters per year. Ransomware hit imaging (PACS) during clinical hours. EHR and lab were operational but unverified. Customer identity withheld under confidentiality.
At 14:32 imaging workstations started returning unreadable files. Within an hour, radiology was offline across all six hospitals. The clinical question was urgent: was the EHR safe? Was the lab system safe? If yes, the care delivery infrastructure could keep running while imaging recovered separately. If no, the entire health system needed to be isolated.
The customer's existing backup tools could restore individual workloads, but not verify them as clean. The recovery team faced a worst-case choice: a blanket rollback of every clinical system, which would stop the EHR and the lab and turn the incident into a multi-day care-delivery outage.
Cybersnap.io scanned EHR, imaging, and lab as three separate workload populations. Per-workload recovery candidates were ranked independently.
Patient records, scheduling, and clinical documentation systems showed no ransomware indicators across 24 hours of snapshot history. Clinical operations could continue.
LIS and diagnostic systems were verified independently. Lab results continued to deliver normally to patient care teams.
PACS and radiology systems were isolated. Their closest clean snapshot, SS-03:00, was identified within minutes. Sandbox validation confirmed clean restore.
Radiology came back online from SS-03:00 within hours, separately from the rest of the clinical environment. No data loss beyond the 3-hour compromise window.
Cybersnap.io exported the full per-workload scan evidence and verdict log for the HIPAA breach analysis and state breach notification review.
