Cybersecurity Threat Landscape in the US Healthcare Sector: Trends, Risks, and National Implications

Author(s) Jochebed, Abimbola, Nicholas
Country United States
Abstract The U.S. healthcare sector faces escalating cybersecurity threats that jeopardize patient safety, data privacy, and operational continuity. Rapid digital transformation, driven by electronic health records (EHRs), telehealth, and Internet of Medical Things (IoMT) devices, has expanded the attack surface, while outdated infrastructure and fragmented governance leave organizations vulnerable. This review paper investigates the evolving cybersecurity threat landscape in the United States healthcare industry, concentrating on trends, risks, threat actors, and policy implications. Healthcare companies are becoming more vulnerable to cyber threats as they undergo rapid digital transformations driven by electronic health records (EHRs), telehealth expansion, and the proliferation of Internet of Medical Things (IoMT) devices. The review takes a methodical approach, combining peer-reviewed literature, industry reports, and regulatory analyses to evaluate the nature and effect of important threats such as ransomware, phishing, insider risks, device vulnerabilities, and supply-chain attacks. The key findings show that healthcare institutions are particularly vulnerable due to antiquated infrastructure, fragmented governance, limited cybersecurity expenditures, and life-critical operational demands. Ransomware instances highlight the systemic threats created by vendor interdependence and poor cyber hygiene. The study discusses new vulnerabilities such as AI-driven attacks and quantum concerns, as well as current mitigating mechanisms like HIPAA, HITECH, NIST CSF, and FDA device advice. Implications for research, policy, and practice include the critical need for integrated cybersecurity governance, workforce development, vendor responsibility, and zero-trust architecture implementation. The assessment recommends targeted assistance for rural and marginalized providers, improved threat intelligence sharing, and additional research into predictive analytics and cross-sector resilience. Finally, safeguarding healthcare systems is more than a technical challenge; it is a national responsibility linked to patient safety and public trust.
