Healthcare Ransomware Tabletop Exercise: EHR Down at 2 a.m.
A healthcare ransomware tabletop exercise: EHR and imaging encrypted overnight, ambulance diversion, paper downtime and HIPAA decisions. 9 injects, 3 hours.
A healthcare ransomware tabletop exercise rehearses what happens when a hospital loses its electronic health record, imaging and clinical systems to encryption, and every IT decision becomes a patient-safety decision. It tests downtime procedures, ambulance diversion, clinical workflows, HIPAA obligations and restoration priorities in one three-hour session.
This hospital cyberattack tabletop is built for a mixed group of executives, clinical operations leaders and legal. The technical story is familiar from the generic ransomware scenario; what changes is the stakes. Clinical content is kept deliberately general so that any acute hospital can adapt it to its own services and regional arrangements.

Starting situation
Read this aloud to players:
You are a 350-bed regional hospital with an emergency department, two intensive care units, surgical theatres and an on-site laboratory and imaging service. The EHR, the imaging archive (PACS) and the laboratory system run in the hospital's own data centre.
It is Saturday, 02:10. Night staffing is in place: one IT engineer on site, a CISO and CIO on call, and an administrator on call from the executive team. The emergency department is busy; two ambulances are en route. Your last full downtime drill was four years ago.
Injects timeline
| # | Time | Inject | Delivered to | What players should address |
|---|---|---|---|---|
| 1 | T+00:00 | Nurses on several wards cannot log in to the EHR; the ED tracking board has frozen | IT on site → IT on call | Triage, escalation, clinical notification |
| 2 | T+00:20 | Imaging archive and lab interfaces stop; ransom notes found on several servers; core services have been stopped | IT on call → CISO | Incident declaration, scope, command activation |
| 3 | T+00:45 | CISO recommends isolating the data centre network, cutting the remaining clinical systems | Administrator on call | Containment authority, clinical impact, downtime activation |
| 4 | T+01:30 | ED lead: no imaging reads or lab results in the system; asks whether to request ambulance diversion | Administrator on call / CMO | Diversion criteria, regional coordination |
| 5 | T+03:00 | Pharmacy running on printed medication lists; lab reporting results by phone; a near-miss is reported | Pharmacy / lab leads → CNO | Downtime workflows, patient safety |
| 6 | T+06:00 | Backup snapshots were deleted; an offline copy is four days old; full EHR restore estimated at 5–7 days | CIO | Recovery options, restoration priority |
| 7 | T+10:00 | Health authority and neighbouring hospitals ask how long diversion will last; law enforcement returns your call | Administrator on call / legal | External coordination, law enforcement |
| 8 | T+14:00 | Local television crew at the ED entrance; staff asking what to tell patients | Communications | Public statement, staff and patient messaging |
| 9 | T+30:00 | Attacker posts sample patient records on a leak site; privacy officer raises HIPAA notification | Privacy officer / legal | Breach assessment, notification timelines |
Module 1 — Detection and command (T+00:00 to T+00:45)
Inject 1. At 02:10, nurses on three wards call the service desk: EHR logins fail with a database error. The ED tracking board has frozen with the last patient added at 02:04. The on-site engineer restarts an application server without effect and calls the on-call IT manager.
Inject 2. Twenty minutes later, radiographers report that the imaging archive is unreachable, and the laboratory analysers can no longer send results to the EHR. The on-call engineer finds text files demanding payment on several servers. Database and interface services have been stopped on the affected servers, apparently deliberately.
Inject 3. The CISO joins the call: "We need to isolate the data centre network from the rest of the hospital and from the internet now. That takes down anything still working, including the medication dispensing interfaces. I need a decision from the administrator on call."
Discussion questions:
- Who tells the clinical leadership, and how quickly? Does the administrator on call know this is their decision?
- At what point do you activate hospital incident command? Who is the incident commander, and where does IT sit in the structure?
- What clinical systems are still working, and what will stop if you isolate the network? Who can answer that at 02:45?
- How are downtime procedures activated across the hospital at night? Where are the paper forms, and does everyone know?
- Which communication channels do you use if email and the internal directory are affected? See out-of-band communications.
Module 2 — Clinical operations in downtime (T+01:30 to T+06:00)
Inject 4. The ED lead calls command: "We have no access to prior records, radiologists cannot see images from the archive, and lab results are coming back by phone. I have two ambulances inbound and a possible stroke patient. Do we go on diversion?"
Inject 5. The pharmacy lead reports that the team is verifying orders from printed medication lists generated before the outage, which are now several hours old. The laboratory is phoning critical results to wards and logging them on paper. A nurse reports a near-miss: a dose was almost repeated because the previous administration was recorded in the EHR and not visible on paper.
Inject 6. The CIO reports that the attacker deleted the online backup snapshots. An offline copy exists but is four days old, and the most optimistic estimate for restoring the EHR is five to seven days. Imaging and lab could be restored earlier if they are prioritised.
Discussion questions:
- What criteria trigger diversion, who decides, and how is the regional system informed? Is diversion partial (for example, stroke and trauma only) or total?
- How do you protect patients already in the building? Which units are most exposed during downtime?
- How are medication administration, orders and results reconciled when the EHR returns? Who owns that plan?
- Who decides restoration priority: IT, clinical leadership or both? What order would you choose, and why?
- Is four days of data loss acceptable? What clinical information from those days exists only on paper or in people's heads?
Module 3 — Coordination, communication and obligations (T+10:00 to T+30:00)
Inject 7. The regional health authority asks how long diversion will last and whether you need to transfer patients. Two neighbouring hospitals report that their emergency departments are filling. A law enforcement agent returns your call and asks for indicators of compromise and whether you have been contacted by the attacker.
Inject 8. A local television crew is filming at the ED entrance and interviewing families who were told to go elsewhere. Staff are messaging managers asking what they can say to patients, and some are posting on social media.
Inject 9. Threat intelligence reports that the attacker has published a sample of files on its leak site, including discharge summaries and a spreadsheet of patient demographics. The privacy officer asks legal to start the HIPAA breach assessment and notification planning.
Discussion questions:
- Who is the single point of contact for the health authority, and how often do you update them? What information do neighbouring hospitals need?
- What do you share with law enforcement, and who approves it?
- Who approves the public statement? How do you reassure patients without overstating how quickly services will return?
- What do staff say to patients and families? Have you briefed them before the media did?
- Under the HIPAA Breach Notification Rule, individuals must be notified without unreasonable delay and no later than 60 days after discovery; breaches affecting 500 or more residents of a state or jurisdiction also require notice to prominent media, and 500 or more require contemporaneous notice to HHS. Who owns that timeline, and when does the clock start?
Discussion questions
Consolidated themes for the hotwash:
- Command: Did IT and clinical leadership work in one command structure, or in parallel? Who made the decisions that mattered?
- Downtime readiness: Did paper procedures work as written? What was missing: forms, printers, staff familiarity, pre-printed patient lists?
- Patient safety: Where was the highest clinical risk, and was it identified by the right people early enough?
- Restoration priority: Is clinical criticality documented in the contingency plan, with realistic restore times? See recovery time objective.
- Obligations: Which notification clocks started, and who tracks them? For more on HIPAA exercise requirements, see the HIPAA tabletop exercise guide.
Curveballs / optional injects
Use one or two if the group is moving quickly:
- The blood bank system is also affected, and the lab cannot confirm compatibility electronically.
- The attacker contacts a patient directly, threatening to publish their records unless they pay.
- A medical device vendor asks to connect remotely to check whether its devices are affected.
- The CEO is abroad and wants to be consulted on every major decision by phone.
Facilitator notes
Expected decisions. A strong team activates hospital incident command within the first hour, with IT represented inside it rather than reporting from outside. It isolates the network with an explicit decision by the administrator on call, declares downtime across the hospital, and makes a documented diversion decision using clinical criteria and the regional process. Restoration priorities are agreed by clinical and IT leaders together, a reconciliation plan for the downtime period is assigned, and one person owns external coordination.
Common pitfalls.
- IT works the problem for an hour before clinical leadership is told.
- Downtime forms exist but nobody knows where they are, and the printers that produce patient lists depend on the encrypted systems.
- Restoration order is chosen by what is technically easiest rather than what is clinically most urgent.
- Diversion is treated as all-or-nothing, without considering partial diversion or transfers.
- The breach assessment is postponed until recovery, even though data theft is already visible.
On clinical realism. Keep clinical detail general and let your own clinicians fill it in. The aim is to test decisions and communication, not clinical knowledge. If you have a clinical safety officer, ask them to review the injects before the session and to play the role of a ward that raises safety concerns.
On regulatory detail. Use only what your compliance team confirms. The HIPAA Security Rule requires security incident procedures (§164.308(a)(6)) and a contingency plan (§164.308(a)(7)), and the Breach Notification Rule sets the deadlines quoted in Module 3. HHS 405(d) Health Industry Cybersecurity Practices is voluntary guidance that many hospitals use as a benchmark. The exercise is not legal advice.
Adapting the audience. For an executive session, summarise Module 1 in a short briefing and spend the time on injects 4, 6, 7 and 9. For a clinical operations session, expand Module 2 with unit-level downtime walkthroughs and the reconciliation process. You can run this scenario live with the exercise runner, which releases injects to players' phones and records decisions for the after-action report.
Evaluating the exercise
| Capability | What good looks like | Red flags |
|---|---|---|
| Incident command | Hospital command activated early; IT and clinical leaders in one structure | Parallel IT and clinical responses; unclear incident commander |
| Downtime procedures | Downtime declared hospital-wide; forms and patient lists available; gaps logged | Staff improvise; nobody can find forms |
| Diversion decision | Clinical criteria applied, regional process followed, decision recorded and reviewed | Decision delayed or made without regional coordination |
| Restoration priority | Order agreed by clinical and IT leads, based on clinical criticality and tested restore times | IT chooses order alone; restore times unknown |
| External coordination | One owner for health authority, neighbouring hospitals and law enforcement | Conflicting updates to external partners |
| Breach and communications | HIPAA timeline owned; consistent messages to patients, staff and media | Breach assessment deferred; staff learn from the news |

Frequently asked questions
What makes a healthcare ransomware tabletop different from a standard ransomware exercise?
Patient safety. In most organisations, ransomware is a business outage; in a hospital, lost access to records, imaging, lab results and medication systems changes clinical risk within minutes. A healthcare exercise must therefore include clinical leaders alongside IT, and test downtime procedures, ambulance diversion decisions and restoration priorities based on clinical criticality rather than IT convenience.
Who should take part in a hospital cyberattack tabletop?
Include the administrator on call or incident commander, the CIO and CISO, the chief medical and chief nursing officers, emergency department, pharmacy and laboratory leads, the privacy officer, legal counsel, communications and the emergency management coordinator. Without clinical leaders, the group will make technical decisions that ignore how care is actually delivered during downtime.
Does a HIPAA tabletop exercise satisfy the contingency plan testing requirement?
It can contribute. The HIPAA Security Rule's contingency plan standard, 45 CFR §164.308(a)(7), includes testing and revision procedures as an addressable implementation specification. A documented tabletop with findings and follow-up actions is useful evidence, but discuss with your compliance team whether it covers everything your plan requires, such as technical restore tests.
How often should hospitals practise EHR downtime procedures?
There is no single mandated frequency, but downtime procedures only work if staff have used them recently. Many hospitals combine short unit-level drills with a larger annual exercise. An EHR downtime exercise like this one shows quickly whether forms are available, whether staff know where they are, and how results reach clinicians without the system.
