The FBI Healthcare Cyber Advisory alerts you to the most pressing cyber risks targeting hospitals and clinics and equips you with concrete steps to reduce exposure. It emphasizes protecting patient safety, preserving clinical operations, and maintaining the confidentiality, integrity, and availability of health data.

Use the advisory to align executives, clinical leaders, and IT teams around a common risk picture. It translates threat intelligence into actionable controls, so you can prioritize investments that measurably lower the likelihood and impact of disruptive incidents such as ransomware attacks and data theft.

Purpose and scope

• Highlight current adversary tactics against healthcare delivery organizations.
• Provide prioritized mitigation guidance you can implement quickly and safely.
• Reinforce the need for incident response planning tied to clinical downtime procedures.

Who should act

Executives, CISOs, IT leaders, clinical engineering, and emergency management teams should use the advisory to validate existing safeguards, close gaps with targeted upgrades, and rehearse coordinated response across the enterprise.

Identification of Current Cyber Threats

Healthcare remains a high-value target due to time-sensitive care, complex vendor ecosystems, and legacy clinical technology. Adversaries increasingly blend extortion and disruption to force rapid payment or data leakage concessions.

Top threats to hospitals and clinics

• Ransomware attacks leveraging stolen credentials, unpatched vulnerabilities, or remote access exposures, often paired with data exfiltration (double extortion).
• Phishing and spear-phishing that bypass basic filtering and trick staff into credential disclosure or malware execution, demanding robust phishing mitigation.
• Exploitation of internet-facing systems, VPNs, and remote desktop services to gain initial footholds and move laterally.
• Third-party and supply chain compromises, including managed service providers, EHR add-ons, and medical device vendors.
• Business email compromise leading to fraudulent payments, altered prescriptions, or unauthorized health data release.
• Insider misuse—malicious or accidental—resulting in unauthorized access, data loss, or policy violations.
• Denial-of-service attacks degrading patient portals, telehealth, or critical integration engines.
• Compromised IoT/IoMT devices and clinical systems with weak hardening or unsupported software.

Threat trends to watch

Attackers continue to automate reconnaissance, rapidly weaponize newly disclosed vulnerabilities, and monetize stolen records. They target backup infrastructure first, then clinical interfaces, and finally public channels for pressure. Expect shorter dwell times and faster pivoting between access, exfiltration, and extortion.

Implementation of Mitigation Strategies

Prioritize layered controls that reduce the most common attack paths. Focus on identity, endpoint, and network defenses, and pair them with resilient recovery.

High-impact quick wins (next 30–60 days)

• Enforce multi-factor authentication on all remote access, administrator accounts, email, and EHR logins.
• Harden email security with modern filtering, banner tagging, attachment sandboxing, and DMARC enforcement to strengthen phishing mitigation.
• Inventory and patch internet-facing systems first; disable unused remote desktop and close exposed management ports.
• Implement network segmentation to isolate clinical networks, administrative systems, backups, and medical devices.
• Adopt immutable, offline backups with tested restores for EHR, imaging, and core integrations.

Foundational controls (60–180 days)

• Conduct routine vulnerability assessments and risk-based patching, prioritizing exploitable and high-impact findings.
• Deploy endpoint detection and response with threat hunting on servers, workstations, and select clinical devices where feasible.
• Apply least-privilege access, password vaulting, and just-in-time elevation for administrators.
• Enable centralized logging and alerting; correlate identity, endpoint, and network events to speed detection.
• Strengthen data encryption for data in transit and at rest, including backups and portable media.

Technical hardening of clinical and legacy systems

• Use compensating controls (application whitelisting, jump boxes, virtual patching) where patching is constrained.
• Create dedicated VLANs for IoT/IoMT; block east–west traffic except for explicitly required protocols.
• Restrict outbound traffic to known destinations; egress filtering can disrupt command-and-control.
• Document vendor support paths and emergency maintenance windows for rapid remediation.

Impact Assessment on Healthcare Facilities

Quantify cyber risk in clinical terms so leaders can weigh trade-offs and allocate resources. Map each critical service to technology dependencies, and model how disruptions translate into patient safety impacts and operational delays.

Clinical operations and patient safety

• Procedure delays, imaging backlogs, and lab turnaround slowdowns that alter care pathways.
• Ambulance diversion and elective surgery cancellations during EHR or network outages.
• Medication and order-entry errors when switching to paper downtime procedures.
• Care coordination breakdowns across referrals, discharge planning, and telehealth.

Financial, reputational, and regulatory impact

• Revenue loss from canceled appointments, extended lengths of stay, and billing disruptions.
• Incident response, forensics, restoration, and overtime costs following major events.
• Regulatory reporting, potential penalties, and long-term trust erosion among patients and partners.

Measuring and communicating risk

• Track mean time to detect, contain, and recover; set recovery time and point objectives for critical apps.
• Run tabletop exercises and quantify outage impacts on throughput, diversion hours, and bed availability.
• Use heat maps tying threats to services (ED, OR, pharmacy) to prioritize controls and investments.

Recommended Security Practices

Build a sustainable program that blends culture, governance, and technology. The goal is to prevent, detect, and recover without compromising patient care.

People and culture

• Deliver role-based training for clinicians, schedulers, revenue cycle, and IT on phishing mitigation and secure workflows.
• Foster a no-blame reporting culture; reward early escalation of suspicious activity.
• Define clear accountability for cyber risk at the executive and board levels.

Process and governance

• Maintain current asset and data inventories, including medical devices and third-party services.
• Institutionalize change management and configuration baselines for clinical systems.
• Schedule periodic vulnerability assessments and independent penetration testing.
• Embed security requirements in procurement and vendor due diligence; evaluate integrations before go-live.

Technology and controls

• Standardize network segmentation, secure remote access, and privileged access management.
• Apply data encryption across endpoints, servers, storage, and backups.
• Adopt zero-trust principles: verify explicitly, use least privilege, and assume breach.
• Continuously validate backups, failover procedures, and alternative clinical workflows.

Collaboration with Cybersecurity and Law Enforcement

Pre-established relationships accelerate response and reduce harm. Engage cybersecurity partners and law enforcement before an incident to clarify points of contact, evidence handling, and notification triggers.

Before an incident

• Identify your regional FBI contacts and document escalation paths in the incident response plan.
• Join trusted information-sharing communities to receive and contribute timely threat intelligence.
• Align legal counsel, privacy, compliance, and communications on decision frameworks for notifications.

During and after an incident

• Preserve logs, volatile memory, and relevant system images; avoid actions that destroy evidence.
• Coordinate with law enforcement on deconfliction, extortion handling, and indicators of compromise.
• Share sanitized findings to help peers defend against similar campaigns while protecting patient privacy.

Incident Response and Recovery Planning

Your incident response planning should be tightly integrated with clinical downtime and recovery playbooks. Focus on speed, clarity, and safety to minimize patient care disruption.

Core playbooks

• Ransomware: rapid isolation, privilege reset, forensic triage, data restoration, and secure rebuilds.
• Data breach: containment, scoping, data discovery, legal review, and notification workflows.
• Denial-of-service: traffic filtering, service failover, and alternative patient access channels.
• Medical device compromise: device isolation, vendor coordination, and compensating controls.

Operational readiness

• Maintain a current contact tree covering executives, clinical leaders, IT, legal, and law enforcement.
• Pre-stage gold images, configuration baselines, and offline backups; test restores quarterly.
• Exercise cross-functional scenarios that invoke manual workflows and evaluate patient safety risks.
• Define success metrics: time to isolate, time to restore core apps, and variance from RTO/RPO.

Conclusion

The FBI Healthcare Cyber Advisory underscores a clear path: reduce the most common attack vectors, harden identities and networks, and practice recovery until it is routine.
