Healthcare Cybersecurity

The Healthcare Threat Landscape

Healthcare remains one of the most targeted sectors in cybersecurity. The average cost of a healthcare data breach has exceeded $10 million, making it the most expensive industry for breaches for over a decade. Ransomware groups such as LockBit, BlackCat/ALPHV, and Cl0p have repeatedly targeted hospital networks, encrypting electronic health records (EHR) and disrupting clinical operations at critical moments.

Threat actors are drawn to healthcare for several reasons: the high value of protected health information (PHI) on dark web markets, the urgency of hospital operations that makes organizations more likely to pay ransoms, and the expanding attack surface created by connected medical devices, telehealth platforms, and cloud-based clinical applications.

Nation-state actors have also turned their attention to healthcare, targeting pharmaceutical research, vaccine development data, and clinical trial information. The convergence of IT and operational technology (OT) in modern hospitals creates unique vulnerabilities where a compromised network segment can directly impact patient safety.

Compliance and Regulatory Requirements

Healthcare organizations operate under some of the strictest data protection regulations in any industry. Navigating this complex regulatory environment requires specialized expertise and continuous monitoring.

• HIPAA (Health Insurance Portability and Accountability Act) — The Security Rule mandates administrative, physical, and technical safeguards for electronic PHI. The Breach Notification Rule requires reporting incidents affecting 500+ individuals to HHS within 60 days.
• PHIPA (Personal Health Information Protection Act) — Ontario's provincial health privacy legislation governs the collection, use, and disclosure of personal health information by health information custodians across Canada.
• HITECH Act — Strengthens HIPAA enforcement with increased penalties for non-compliance and mandatory breach notification requirements for business associates.
• PIPEDA / Provincial Health Privacy Laws — Canadian healthcare organizations must comply with federal and provincial privacy legislation governing health information across jurisdictions.
• FDA Premarket Cybersecurity Guidance — Medical device manufacturers must address cybersecurity in device design, including Software Bill of Materials (SBOM) requirements for new device submissions.
• NIST Cybersecurity Framework (CSF) — Widely adopted in healthcare as a voluntary framework for managing cybersecurity risk across the organization.

Medical Device Security

The proliferation of connected medical devices (IoMT) has created an enormous and often poorly managed attack surface. Infusion pumps, patient monitors, imaging systems, and surgical robots all connect to hospital networks, yet many run legacy operating systems that can no longer receive security patches. A single compromised device can serve as a pivot point for lateral movement across the entire clinical network.

Mjolnir Security conducts comprehensive medical device risk assessments that inventory all connected devices, evaluate firmware vulnerabilities, assess network segmentation controls, and provide remediation roadmaps aligned with FDA guidance and IEC 62443 standards. Our approach accounts for the clinical context of each device, ensuring that security controls never compromise patient care delivery.

EHR and Clinical Application Protection

Electronic Health Record systems like Epic, Cerner (Oracle Health), and MEDITECH represent the operational backbone of modern healthcare. These platforms contain the entirety of a patient's medical history and are integrated with pharmacy, laboratory, radiology, and billing systems. A compromise of the EHR can halt clinical operations across an entire health system.

Mjolnir provides continuous monitoring of EHR environments, including user behavior analytics to detect unauthorized access to patient records, privileged access management for database administrators, and real-time alerting on anomalous data exfiltration patterns. We work directly with EHR vendors to ensure that security configurations follow vendor hardening guides and industry best practices.

Mjolnir's Healthcare Security Approach

Our healthcare practice is built on direct experience responding to breaches at hospitals, health systems, pharmaceutical companies, and medical device manufacturers. We understand that security measures must operate within the constraints of clinical workflows, regulatory requirements, and 24/7 patient care operations.

We deploy healthcare-specific threat intelligence sourced from the Health Information Sharing and Analysis Center (H-ISAC) and our own darknet monitoring capabilities to provide early warning of campaigns targeting the healthcare sector. Our incident response retainer clients benefit from pre-staged forensic toolkits and runbooks tailored to healthcare environments, ensuring rapid containment when minutes matter.

From HIPAA gap assessments and penetration testing of clinical networks to full SOC-as-a-Service monitoring of multi-site health systems, Mjolnir delivers the depth of expertise that healthcare organizations need to protect their patients, their data, and their operations.
