Red Teaming for Healthcare: Protecting Patient Data and Medical Systems

Why Healthcare Organizations Need Red Teaming

Healthcare is the most targeted sector for ransomware and the most expensive for breaches. 73% of healthcare entities reported a cyber incident in 2025 (Ponemon Institute). The average healthcare breach cost USD 7.42 million (IBM, 2025), nearly double the cross-industry average and the highest of any sector for the 15th consecutive year. In healthcare, a security failure does not just cost money. It endangers patients.

Yet healthcare lags far behind other critical infrastructure in testing maturity. Only 34% of healthcare organisations have ever run a red team assessment. Only 52% conduct even annual penetration testing. Hospitals operate 24/7, cannot easily patch live systems, depend on medical devices with 10-15 year lifecycles, and manage the most sensitive category of personal data. The gap between threat exposure and defensive validation is the single largest cybersecurity risk in the sector.

This guide covers the threat landscape, regulatory requirements, and practical red team implementation for hospitals, clinics, insurers, and medical device manufacturers.

What Are the Primary Cyber Threats to Healthcare Organizations?

Ransomware: The Existential Threat

Ransomware is the dominant threat to healthcare organisations, and the one with the most immediate life-safety implications. When hospital systems go down, care delivery is directly impacted.

Healthcare ransomware statistics for 2025-2026:

Metric	Value
Healthcare entities reporting cyber incidents (2025)	73%
Ransomware attacks on hospitals (global, 2025)	389
Average ransom demand to hospitals	USD 1.2M
Average hospital downtime from ransomware	18.7 days
Patient diversions due to ransomware (US, 2025)	142 incidents
Estimated excess mortality linked to hospital cyber incidents	Under study
Healthcare organisations paying ransom	42%

The 2025 attack on a major European hospital group demonstrated the life-safety implications: emergency departments were forced to divert patients for 11 days, elective surgeries were cancelled for three weeks, and patient records were inaccessible for 23 days. Post-incident analysis estimated that the attack contributed to measurable delays in care for over 2,400 patients.

Data Theft and Patient Privacy Breaches

Healthcare data is among the most valuable on the dark web, commanding prices of USD 250-1,000 per complete medical record compared to USD 5-50 for financial records. This premium reflects the richness of medical records (which include financial, identity, and health information) and their utility for insurance fraud, identity theft, and extortion.

Healthcare data breach statistics:

Average cost per breached healthcare record: USD 614 (vs. USD 169 cross-industry average)
Average records exposed per healthcare breach: 17,400
Time to identify a healthcare breach: 213 days (vs. 194 days cross-industry)
Time to contain a healthcare breach: 72 days (vs. 64 days cross-industry)

Medical Device Vulnerabilities

The proliferation of connected medical devices — from MRI machines and infusion pumps to patient monitors and surgical robots — has created an enormous and largely untested attack surface. Medical devices often run legacy operating systems, lack encryption, use hard-coded credentials, and cannot be easily patched.

Medical device security statistics:

82% of healthcare red team engagements that include medical device testing discover exploitable vulnerabilities (Cynerio, 2025)
53% of connected medical devices run on known vulnerable operating systems (Armis Healthcare IoT Security Report, 2025)
Average number of connected medical devices per hospital bed: 10-15
Percentage of medical devices with known critical vulnerabilities: 38%
Average time to patch a medical device vulnerability: 287 days

“Medical device security is the most underappreciated risk in healthcare cybersecurity. These devices are literally connected to patients, yet many run Windows XP or have no authentication at all. Red teaming is essential to understand the real-world risk these devices pose.” — Beau Woods, Cyber Safety Innovation Fellow, Atlantic Council

Insider Threats

Healthcare organisations face elevated insider threat risk due to:

Large, diverse workforces with varying levels of security awareness
Widespread legitimate need for access to patient records
High employee turnover, particularly among clinical staff
Complex credential management across multiple systems
Financial pressures that may motivate data theft

Insider threat statistics in healthcare:

58% of healthcare data breaches involve internal actors (Verizon DBIR, 2025)
Average insider-caused breach cost: USD 4.8 million
Time to detect insider breach: 291 days (vs. 213 days for external attacks)

Supply Chain and Third-Party Risks

Healthcare organisations depend on numerous third-party vendors for EHR systems, medical devices, billing platforms, and clinical applications. Each vendor relationship represents a potential attack vector.

Average number of third-party vendors with network access to a hospital: 1,300+
Percentage of healthcare breaches involving a third party: 32%
Average cost increase when a third party is involved in a breach: +23%

What Should a Healthcare Red Team Assessment Cover?

Scope Framework for Healthcare Red Teaming

An effective healthcare red team assessment should address the organization’s unique attack surface across multiple domains:

1. Clinical Network Assessment

The clinical network, which connects EHR systems, medical devices, diagnostic equipment, and clinical workstations, is the highest-priority testing domain:

Segmentation between clinical and administrative networks
Access controls on EHR systems (Epic, Cerner, etc.)
PACS (Picture Archiving and Communication System) security
Clinical decision support system integrity
Pharmacy dispensing system access
Laboratory information system (LIS) security

2. Medical Device Security Testing

Medical device testing requires specialized expertise and careful safety protocols:

Network-connected device discovery and inventory validation
Default credential testing across device categories
Communication protocol analysis (HL7, DICOM, FHIR)
Device firmware analysis for known vulnerabilities
Network segmentation validation for medical devices
Biomedical device management system access

Important safety consideration: Red team testing of medical devices must never be conducted on devices actively connected to patients. Testing should use dedicated test units, decommissioned devices, or simulation environments that replicate the production network.

3. Physical Security Testing

Physical security is critical in healthcare environments where access to restricted areas can enable both cyber and physical attacks:

Emergency department access controls
Pharmacy and medication storage areas
Server rooms and network closets
Medical records storage (physical and digital)
Operating room and ICU access controls
Badge cloning and tailgating tests

4. Social Engineering

Healthcare workers are frequently targeted through social engineering due to their orientation toward helping others and the high-pressure nature of clinical environments:

Phishing campaigns targeting clinical and administrative staff
Pretexting as vendors, patients, or visiting clinicians
Telephone-based social engineering (vishing) targeting the help desk
Physical social engineering at reception and nursing stations
USB drop tests in clinical and administrative areas

5. Administrative and Business Systems

Back-office systems that support healthcare operations:

Billing and revenue cycle management systems
Human resources and payroll systems
Supply chain and procurement platforms
Patient portal and telehealth platforms
Cloud-hosted applications and data stores

Red Team Scenarios for Healthcare

Scenario 1 — Ransomware Simulation: Simulate a ransomware attack from initial phishing email through lateral movement to the point of encryption readiness. Test the organization’s ability to detect, contain, and recover. Validate backup integrity and recovery time objectives (RTOs).

Scenario 2 — Patient Data Exfiltration: Simulate an attacker targeting patient records for sale on the dark web. Test data loss prevention controls, database access controls, and monitoring capabilities across EHR systems and data warehouses.

Scenario 3 — Medical Device Compromise: Simulate an attacker gaining access to the clinical network through a vulnerable medical device. Test segmentation controls, device monitoring capabilities, and lateral movement opportunities from device networks to clinical systems.

Scenario 4 — Insider Threat Simulation: Simulate a malicious insider (clinical or administrative staff) attempting to exfiltrate patient data or manipulate clinical records. Test access controls, audit logging, and anomaly detection capabilities.

Scenario 5 — Supply Chain Compromise: Simulate compromise through a third-party vendor with network access. Test vendor access controls, segmentation between vendor and clinical networks, and monitoring of third-party activity.

For healthcare organisations seeking to implement these scenarios, specialized red team providers with healthcare experience can design assessments that address clinical safety considerations while providing realistic adversary simulation.

What Are Common Red Team Findings in Healthcare?

Based on aggregated data from healthcare red team engagements, the most frequently identified findings include:

Finding	Frequency	Severity
Flat network architecture (inadequate segmentation)	84%	Critical
Default or shared credentials on medical devices	78%	Critical
EHR access control misconfigurations	72%	High
Lack of monitoring on clinical network segments	69%	High
Legacy operating systems on medical devices	67%	High
Excessive user privileges in clinical applications	63%	High
Unencrypted medical device communications	61%	Medium-High
Physical security gaps in clinical areas	58%	Medium
Insufficient backup testing and offline backup capability	54%	Critical
Weak help desk authentication procedures	51%	High

The most critical systemic finding is inadequate network segmentation. In 84% of healthcare red team engagements, the red team can move laterally from an initial foothold in the administrative network to clinical systems, medical devices, and sensitive data stores without encountering effective segmentation controls.

How Do Healthcare Data Protection Regulations Affect Red Teaming?

Swiss Federal Act on Data Protection (nFADP)

Switzerland’s revised Federal Act on Data Protection (nFADP), effective since September 2023, classifies health data as “sensitive personal data” subject to enhanced protection requirements. Red team assessments help organisations validate compliance with:

Data processing security requirements (Art. 8 nFADP)
Data breach notification obligations (Art. 24 nFADP) — testing whether breaches would be detected within the 72-hour notification window
Data protection impact assessment validation (Art. 22 nFADP)
International data transfer controls (Art. 16-17 nFADP)

For Swiss healthcare organisations that process data of EU residents or operate in the EU:

Article 32: Requires “appropriate technical and organizational measures” including “a process for regularly testing, assessing and evaluating the effectiveness of technical and organizational measures for ensuring the security of processing”
Red team assessments directly satisfy the Article 32 requirement for regular testing
Data protection authorities have increasingly referenced adversary simulation as a best practice

HIPAA (for organisations with US operations)

For Swiss healthcare organisations with US operations or partnerships:

HIPAA Security Rule requires regular risk assessments and security testing
Red team assessments exceed HIPAA’s minimum testing requirements and demonstrate due diligence
OCR enforcement actions increasingly reference the adequacy of security testing programs

Swiss Hospital and Healthcare-Specific Regulations

Cantonal health legislation: Various cantonal laws impose specific requirements for health data security
EPD (Electronic Patient Dossier): The Swiss electronic patient dossier framework includes security requirements that benefit from red team validation
Healthcare sector certification standards: Organizations certified to ISO 27001 with ISO 27799 (health informatics) must demonstrate regular security testing

How Can Healthcare Organizations Improve Their Cyber Resilience?

Immediate Priorities (0-6 months)

Network segmentation: Implement or validate segmentation between administrative, clinical, medical device, and guest networks. This single measure has the highest impact on reducing attack surface.
Medical device inventory: Establish a complete inventory of all network-connected medical devices, including operating system versions, firmware versions, and known vulnerabilities.
Backup validation: Test backup restoration for all critical systems, including EHR, PACS, and laboratory systems. Ensure at least one backup copy is offline or immutable.
Incident response plan: Develop or update an incident response plan that includes clinical continuity procedures — how patient care continues when IT systems are unavailable.
MFA deployment: Implement multi-factor authentication for all remote access, administrative access, and EHR login.

Medium-Term Improvements (6-18 months)

Red team assessment: Conduct the organization’s first red team assessment, focusing on the most critical clinical systems and patient data stores.
Medical device security program: Establish a medical device security program that includes procurement security requirements, network segmentation, and vulnerability management.
Security awareness training: Implement healthcare-specific security awareness training that addresses clinical workflows and the unique social engineering risks in healthcare.
Third-party risk management: Establish a vendor risk assessment program that includes security requirements for all vendors with network access.
Detection and response capability: Deploy or enhance security monitoring across clinical network segments, not just administrative networks.

Long-Term Maturation (18+ months)

Continuous red team program: Establish ongoing adversary simulation integrated with defensive operations.
Sector collaboration: Participate in healthcare-specific information sharing organisations (H-ISAC or national equivalents).
Zero trust architecture: Begin implementing zero trust principles across clinical and administrative environments.
AI-powered threat detection: Deploy machine learning-based anomaly detection tuned for healthcare network traffic patterns.

Frequently Asked Questions

Is red teaming safe in a hospital environment?

Yes, when conducted by experienced providers following healthcare-specific safety protocols. Red team testing should never be performed on medical devices actively connected to patients. Reputable providers establish clear safety boundaries, emergency stop procedures, and coordinate closely with clinical engineering and biomedical teams.

How much does a healthcare red team assessment cost?

Costs range from CHF 25,000 for focused assessments of small clinics to CHF 200,000+ for full assessments of large hospital systems. The median cost for a mid-size healthcare organization is approximately CHF 80,000-120,000.

How often should healthcare organisations conduct red team assessments?

Annual red team assessments are recommended for large hospital systems and organisations handling large volumes of patient data. Smaller organisations should conduct assessments at least every two years, supplemented by annual penetration testing and quarterly phishing simulations.

What is the biggest cybersecurity risk in healthcare?

Ransomware is the most immediate and impactful threat, with the potential to disrupt patient care and endanger lives. However, the underlying root cause is typically inadequate network segmentation, which allows ransomware (and other threats) to spread from initial compromise to critical clinical systems.

Do medical device manufacturers participate in red team assessments?

Increasingly, yes. Leading medical device manufacturers are engaging in coordinated vulnerability disclosure programs and supporting security testing by healthcare organisations. However, warranty and regulatory concerns can complicate testing, and organisations should coordinate with manufacturers before testing their devices.

How does red teaming help with regulatory compliance?

Red team assessments directly support compliance with data protection requirements (nFADP Art. 8, GDPR Art. 32), demonstrate due diligence in protecting patient data, validate the effectiveness of security controls required by cantonal health legislation, and provide evidence for regulatory audits and inspections.
