Sample Scenario — Healthcare Ransomware Simulation

The Ridgeway Health Ransomware Exercise

A branching, choose-your-path tabletop built for a regional health system. Hospitals can't close for the day, and every technical decision is also a clinical one. Six shared injects establish the attack, then incident command's own decision — go dark system-wide, or isolate and keep the clinical systems running — sends the exercise down one of two independent, fully-scripted paths. Patients keep arriving either way.

Fictional, but built to feel real in the room.

Every detail below is fictional — specific enough to feel real in the room, and generic enough to map onto almost any health system that runs its clinical operations on shared technology.

Ridgeway Health

A nonprofit regional health system headquartered in Knoxville, Tennessee, with four hospitals — including a Level II trauma center — 38 outpatient clinics, 1,100 beds, ~9,500 employees, and $2.4B in annual revenue. All four hospitals share one electronic health record, hosted in Ridgeway's own data center.

Ridgeway has downtime procedures for losing the health record. They were last drilled system-wide three years ago, before a third of today's nurses were hired. The plan assumes the outage is short and the rest of the network is still working. Ransomware doesn't make either assumption.

Ridgeway Medical Center — Level II trauma center, 520 beds
Regional EMS — 14 ambulance services route patients to Ridgeway
Downtime procedures — last system-wide drill three years ago
Cyber insurer — $25M policy, panel forensics firm

The crisis everyone faces.

Six injects, delivered over the first ten hours, that every player experiences regardless of what the room ultimately decides. This phase ends with the decision that splits the exercise in two.

DAY 0
23:40
INJECT 1Detection

The pharmacy cabinets stop talking

Medication dispensing cabinets at two hospitals lose their connection to the pharmacy system. Minutes later, the help desk gets a report of files with an unfamiliar extension on an imaging department share. The on-call engineer logs it as a network issue.

Tests: whether clinical system anomalies after midnight reach the security team — not just IT operations.
DAY 1
02:15
INJECT 2Scoping

Encrypted, and still moving

Security confirms ransomware on about 140 servers, including imaging and the laboratory system. The electronic health record is unaffected so far, but attacker accounts with domain administrator rights are still active on the network.

Tests: scoping an attack that's still in progress, before anyone has the full picture.
04:00
INJECT 3Clinical

No CT reads at the trauma center

With imaging down, radiologists can't read CT scans at the trauma center. The on-call trauma surgeon asks whether to put the hospital on diversion for stroke and trauma patients. Nobody in the incident command structure is sure who has the authority to decide.

Tests: whether clinical leaders are inside incident command — and who can authorize ambulance diversion at 4 a.m.
06:30
INJECT 4Extortion

$9M and a threat to call patients

A ransom note demands $9M and claims 1.2TB of patient data was stolen, including behavioral health records. The attackers threaten to contact patients directly if Ridgeway doesn't respond within 72 hours.

Tests: how quickly counsel, law enforcement, and the insurer are engaged — without letting the ransom question take over the morning.
08:00
INJECT 5Operations

Day shift, paper forms, and stale printouts

Day shift arrives. Downtime forms exist, but half the nurses on the trauma center's med-surg floors have never used them. The printed medication records from the last automatic downtime report are already nine hours old.

Tests: whether downtime procedures work with the staff actually on shift, not the staff who were trained.
09:30
INJECT 6Decision point

Go dark, or isolate

Forensics says the attackers still have privileged access and can't guarantee the health record servers are clean. Going dark means shutting down every network connection and the health record at all four hospitals — paper operations for possibly two to three weeks, and likely diversion. Targeted isolation keeps the health record running while the infected segments are cut off, at the risk that the attackers reach it next. Incident command has to decide.

Tests: balancing containment against clinical continuity, with patient safety on both sides of the decision. This is the fork.

The room decides. The exercise branches.

INJECTS 1–6 DECISION A — GO DARK B — ISOLATE

From here, the facilitator runs one of two fully independent scripts depending on what the room chose in Inject 6. Toggle between them below to see how each one unfolds — in a live session, players only ever see the one they earned.

Path A — incident command goes darkTen injects. Going dark contains the attackers, not the consequences — and it switches off things nobody knew were on the network.
DAY 1
10:15
INJECT 7AShutdown

The phones went with it

The network is shut down and all four hospitals move to paper. Then the internal phone system goes silent — it runs over the same network. Units start using overhead paging, runners, and personal cell phones to coordinate care.

Tests: dependencies nobody mapped, discovered at the worst possible moment.
13:00
INJECT 8ACommunity

Seventy minutes to the next trauma center

Regional EMS diverts trauma and stroke patients away from Ridgeway Medical Center. The next-closest trauma center is 70 minutes away for some rural counties. A neighboring hospital's CEO calls to say his emergency department is already over capacity.

Tests: coordinating with EMS, neighboring hospitals, and state health officials when your outage becomes the region's problem.
DAY 2
09:00
INJECT 9APatient safety

A near-miss on paper

A transcription error on a paper order leads to a patient nearly receiving a double dose of a blood thinner. A nurse catches it at the bedside. It's the third medication near-miss reported since the shutdown.

Tests: patient safety monitoring during extended downtime — and whether near-misses are being reported or quietly absorbed.
DAY 3
07:00
INJECT 10AWorkforce

Sixteen-hour shifts

Nurses are working sixteen-hour shifts to keep up with paper documentation. Agency nurses can't work effectively without the health record, and the nurses' union files a formal safe-staffing concern.

Tests: sustaining a workforce through weeks of downtime, not days.
DAY 4
10:00
INJECT 11AFinance

$14M a week, and nothing billed

Ridgeway hasn't billed a claim in four days and is losing about $14M in cash flow a week. The CFO argues the revenue cycle systems should be restored before some clinical systems, to protect the system's cash position.

Tests: setting restoration priorities when clinical and financial needs compete — and who decides.
DAY 5
08:00
INJECT 12AData leak

Ten thousand records, published

The attackers publish 10,000 patient records on their leak site, including behavioral health notes. Patients begin calling, some in distress. Local media start reading the records.

Tests: patient notification and support when the most sensitive records are already public.
DAY 6
14:00
INJECT 13ARestoration

Six days of paper to put back

Forensics clears the health record environment for restoration from backups. But six days of paper records — orders, notes, medication administrations — now have to be entered back into the system before clinicians can rely on it again.

Tests: the clinical risk of re-entry, when the restored system is only as accurate as the paper behind it.
DAY 7
11:00
INJECT 14ARegulators

How was care kept safe?

Federal and state health regulators ask for an incident report, including how patient safety was maintained during the downtime and how many patients were diverted.

Tests: producing a credible account of clinical decisions made under pressure — from records that were kept on paper.
DAY 8
09:00
INJECT 15ADecision point

Bring the trauma center back first?

The trauma center's systems could be brought back two days before the other hospitals, ending diversion sooner. Forensics warns that a partial restoration increases the risk of reinfection if any attacker foothold remains. Incident command has to decide.

Tests: risk acceptance when the benefit is measured in ambulance minutes and the cost is a second outage.
DAY 10
10:00
INJECT 16ARemediation

The medical devices were on the same network

The post-incident review finds that infusion pumps and patient monitors share a flat network with business systems. Proper segmentation will take about 18 months and $30M that isn't in the capital plan.

Tests: separating short-term recovery from the structural fix the attack exposed.
Path B — incident command isolates and keeps runningTen injects. Isolating keeps clinicians working, not safe — and the outage you avoid on purpose can arrive anyway, without warning.
DAY 1
10:00
INJECT 7BIsolation

Keep the record up

Imaging and laboratory networks are cut off, and the health record stays online. Clinicians are relieved. Nobody writes down what would trigger a full shutdown, or who would call it.

Tests: whether a containment decision comes with clear criteria for escalating it.
14:00
INJECT 8BClinical

Lab results by phone

With the lab system isolated, results are called and faxed to units. Emergency department waits pass six hours, and admitted patients board in hallways while beds wait on lab clearance.

Tests: the hidden cost of partial outages that look manageable from the command center.
22:00
INJECT 9BEscalation

It moved

The attackers use a service account to reach a health record interface server. Two application servers are encrypted before security cuts them off. The health record goes down at two hospitals mid-shift — with no fresh downtime printouts.

Tests: crash downtime: what happens when the outage you avoided arrives without warning.
DAY 2
01:30
INJECT 10BPatient safety

Three hours without medication records

For three hours, nurses at the trauma center have no medication records for 400 inpatients. They reconstruct schedules with pharmacy from memory and handwritten notes. One missed insulin dose is reported.

Tests: patient safety reporting during an unplanned outage, and support for the staff who lived through it.
06:00
INJECT 11BShutdown

Going dark anyway

Incident command shuts down the entire network — the decision it declined the day before, now made at night, after an unplanned outage, with staff already exhausted.

Tests: making the harder decision under worse conditions, and communicating the reversal to clinicians.
11:00
INJECT 12BCommunity

Diversion, again

Ridgeway goes on diversion. EMS leaders are frustrated by the back-and-forth and ask why they weren't warned that a full shutdown was possible.

Tests: partner communications when your earlier message turned out to be wrong.
DAY 4
09:00
INJECT 13BExtortion

Patients get the email

The attackers email several hundred patients directly, attaching excerpts of their own records and urging them to pressure Ridgeway to pay.

Tests: patient communications and support when the attackers reach patients before you do.
DAY 5
15:00
INJECT 14BInsurance

Did the delay void coverage?

The cyber insurer questions whether the decision to keep systems running despite active attacker access breached the policy's duty to mitigate. Coverage for parts of the loss is now in dispute.

Tests: knowing your policy conditions before you make containment decisions, not after.
DAY 7
10:00
INJECT 15BDecision point

Which backups can you trust?

Forensics finds the attackers had access to the backup management console. The most recent backups can't be verified as clean for another week. Offline backups from nine days ago are clean, but restoring them loses nine days of clinical data. Incident command has to decide.

Tests: choosing between speed and data integrity when both carry clinical risk.
DAY 9
11:00
INJECT 16BGovernance

Why did the safer option fail?

The board asks why the option chosen to protect clinical operations ended up causing a worse outage — and whether the decision on Day 1 was made by clinical and technical leaders together.

Tests: accountability that improves decision-making rather than punishing the people who made a judgment call.

What the debrief surfaces.

The two paths are built to converge on the same hard questions, arrived at from opposite directions.

If incident command went dark

  • Did the shutdown decision account for everything else on the network — phones, paging, medical devices?
  • Who had the authority to divert ambulances, and how were EMS and neighboring hospitals brought in?
  • How was patient safety monitored during extended paper downtime, and were near-misses reported?

If incident command isolated and kept running

  • Were there pre-agreed criteria for escalating from targeted isolation to a full shutdown?
  • Did clinicians have current downtime records when the health record went down without warning?
  • Was the Day 1 decision made by clinical and technical leaders together, or by one side for the other?
