How Rapid Digital Transformation is Affecting Healthcare Cybersecurity

Rapid digitalization and increasing interconnectedness have brought incredible benefits to the healthcare industry. Cloud electronic health records, internet-connected medical devices, remote access, and AI‑enabled workflows have improved access, efficiency, and care coordination.

But that same interconnectedness is "exposing clinical technology to threats it was never engineered to withstand," warns cybersecurity firm Trellix. In 2025, Trellix detected 54.7 million incidents across healthcare partners using its products, identifying email as the primary attack vector. As cyber threats to healthcare continue to evolve, the focus is shifting beyond traditional IT systems toward interconnected clinical environments, where an attack can ripple across hospital operations, disrupt care delivery, and ultimately jeopardize patient safety.

This evolving threat landscape underscores the growing need for specialized healthcare cybersecurity professionals and researchers to strengthen the resilience of clinical systems.

The Cost of Digitalized Healthcare

Providers are embracing digital tools to streamline workflows, enable remote care, share data more readily, and reduce costs—all of which are pushing more services to the cloud and connecting a fast-growing Internet of Medical Things (IoMT). However, every new integration creates a larger attack surface, especially when legacy technology and systems were not built for modern cyber threats.

Health data is incredibly valuable, and downtime can affect care, which is why healthcare continues to lead industries in breach costs and is frequently targeted by organized ransomware groups. Healthcare remained the most expensive industry for breaches for the 13th consecutive year at approximately $6.64M as the average cost per breach. To help reduce cyber breaches, US healthcare organizations will spend $35.7 billion on cybersecurity and compliance in 2026, up 18% from 2024. The average hospital spends $1.27 million annually on HIPAA compliance activities, including risk assessments, training, and technology.

Emerging Threats to Healthcare Cybersecurity

Reporting shows a shift in cyber threats from targeting encryption to data theft and patient extortion. This includes tactics that encrypt systems, steal protected health information, then contact patients directly. Two of the most active ransomware groups in 2025 targeting healthcare organizations globally—Qilin and INC Ransom—focused on electronic health record databases and hospital networks, while tactics like relentless phishing using "administrator‑bait” themes around topics like AI transformation and regulatory compliance have become more popular. This data reflects both criminal incentives and persistent security gaps that affect tens of millions of individuals and create systemic risk.

The most worrying pattern is the cascading effect these attacks have on healthcare systems. Operations knocked offline in one area, such as for email or HVAC systems, can ripple into clinical workflows, delay patient care, and even affect mortality and cardiac outcomes across an entire region.

Broader industry analyses reinforce the scale of the problem. Recent data shows that roughly 78% of healthcare organizations have experienced a ransomware attack, with increasingly AI‑assisted techniques complicating defenses and raising the cost of incidents.

Unlike enterprise laptops or cloud apps, wearable health and medical devices like heart monitors and continuous glucose monitors (CGMs), as well as clinical systems may remain in service for a decade or more, running outdated operating systems with difficultly in software patching without disrupting care. For example, an implantable cardioverter-defibrillator (ICD), which detects dangerous heart rhythms and can deliver electrical therapy, is an internal device where software changes must preserve life-saving functions, and updates may require manufacturer-specific clinical programming and testing.

Regulatory obligations, operational requirements, and safety validations can slow replacements or firmware updates, leaving known vulnerabilities in place. Health‑ISAC’s threat reporting highlights exposed imaging servers and devices on unsecured networks to show how IoMT growth has outpaced secure architecture in many environments.

How Healthcare Organizations are Responding to Cyber Threats

To protect against these threats, healthcare organizations must approach cybersecurity not as routine IT maintenance but as a core component of patient safety that requires deliberate strategies to reduce risk across clinical, administrative, and operational systems. Here are a few ways the industry work to protect its systems and patients.

• Prioritize email and identity controls. Use of phishing‑resistant multi-factor authentication, least‑privilege access, and session monitoring to stop initial access before threats can spread.

• Segment networks by function. Separate administrative IT, clinical systems, and operational technologies to support least-privilege access, isolate systems, and reduce the likelihood of cascading failures during an incident.

• Strengthen legacy and IoMT assets. Where patching isn’t feasible, apply additional controls, such as virtual patching and protocol monitoring, to mitigate risk on long lifecycle devices.

• Invest in resilience, not just prevention. IBM emphasizes secure‑by‑design principles for medical devices and systems for robust continuity planning so care delivery can continue during outages.

• Address the human layer. Training, simulations, and culture change remain essential, because many successful attacks still begin with a single human-generated error.

Securing digital health requires experts who understand clinical workflows, regulated data, medical device lifecycles, and the complexities of electronic health records and cloud integrations. The shift in healthcare-related cyber threats toward a patient safety crisis underscores the need for security and health information management professionals who can translate threat intelligence into safe and compliant operations at the bedside and beyond.
