Over the past decade, healthcare has seen a dramatic rise in cyberattacks, significantly affecting hospitals, medical infrastructure, and associated supply chains. High-profile incidents such as the WannaCry ransomware attack in 2017, which crippled 34 UK hospitals, exposed vulnerabilities in healthcare’s digital security. Fast forward to 2024, and Change Healthcare experienced a major cybersecurity breach, resulting in billions of dollars in losses within the U.S. healthcare system.
A separate breach in France compromised the personal data of over 33 million people. These attacks, occurring across different healthcare systems, highlight shared vulnerabilities: patients’ data is exposed, patient safety is jeopardized, and healthcare finances take a hit.
Why Cybersecurity in Healthcare Is Now a Patient-Safety Issue
Healthcare cybersecurity is safeguarding patient care. As healthcare systems digitize rapidly, cybersecurity risks are evolving in both complexity and frequency. Cyberattacks can lead to downtime of core healthcare services, disrupt critical processes such as patient admissions, and compromise access to medical records—all of which affect patient safety. These risks are exacerbated by outdated IT infrastructure, legacy cyber-physical systems, and a lack of cybersecurity awareness among staff.
Moreover, the growing Internet of Medical Things (IoMT), AI-driven decision support systems, and new hospital-at-home models increase the attack surface, making healthcare an increasingly attractive target for cybercriminals. With vulnerabilities entrenched in both operational processes and technology, the healthcare sector finds itself under threat.
Case Studies and Cyberattack Impact in Healthcare
Let’s look at some real-world examples to grasp the gravity of these threats:
- WannaCry (2017): This global attack targeted the UK’s National Health Service (NHS), disrupting operations at 34 hospitals. It led to delays in emergency surgeries, appointments, and patient care, highlighting how ransomware can disrupt essential healthcare services.
- Change Healthcare (2024): A cyberattack in the U.S. disrupted healthcare services, resulting in billions of dollars in financial losses. This attack crippled several hospital systems, affecting day-to-day operations, billing, and patient data access.
- France Health Insurer Breach (2024): The personal data of over 33 million individuals was exposed in a breach that compromised sensitive health information. This attack not only violated patient privacy but also undermined the trust healthcare organizations need to function effectively.
Such incidents illustrate how cybersecurity breaches go beyond data loss; they pose a direct threat to patient safety by disrupting healthcare delivery.
Why Healthcare Is at High Risk
Healthcare systems remain vulnerable to cyberattacks due to several key factors:
- Outdated IT Systems: Many healthcare facilities still rely on legacy IT systems that are difficult to secure and update. These systems often lack the defenses necessary to fend off modern cyber threats.
- IoMT and Device Vulnerabilities: The rise of connected medical devices has brought many new vulnerabilities. Devices like pagers, which were never designed with cybersecurity in mind, are now integral to patient care, making them prime targets for cyberattacks.
- Lack of Cybersecurity Awareness: Healthcare professionals are often not trained to recognize phishing attempts, ransomware threats, or even basic security protocols, leaving healthcare systems exposed.
- Limited Financial Resources: Healthcare providers often face budget constraints that prevent investment in robust cybersecurity measures, such as network segmentation and real-time threat detection.
With the rising use of digital technologies, these vulnerabilities are only set to increase, leaving healthcare systems at constant risk.
The Cost of Inaction: Financial and Operational Impact
The IBM Cost of a Data Breach Report 2023 found that healthcare had the highest average breach cost among sectors, at $10.93 million. This figure is nearly double the global average for all industries. While healthcare accounts for just 5% of cybersecurity incidents, its sensitive data, operational complexity, and outdated systems make it a high-value target for cybercriminals.
Key Cybersecurity Measures Healthcare Needs Right Now
To tackle these cybersecurity challenges, healthcare organizations must prioritize several measures:
- Network Segmentation: This ensures that if one part of the system is compromised, the entire hospital or healthcare network isn’t shut down.
- Real-time Threat Detection and Response: Anomaly detection systems can help identify suspicious activity early, preventing the spread of attacks and enabling rapid response.
- Backup and Recovery Plans: Healthcare organizations need to have backup systems in place to ensure continuity of care during cyberattacks.
- Medical Device Security: Ensuring that connected devices are regularly updated and properly secured is essential to reducing vulnerabilities in the IoMT.
- Cybersecurity Training: Healthcare staff must undergo training to recognize and respond appropriately to cyber threats, such as phishing emails and suspicious activity.
The Regulatory Landscape
Both the EU and the UK are stepping up their efforts to address cybersecurity risks in healthcare through new policies and regulations:
The UK’s Cybersecurity and Resilience Bill (2025) aims to strengthen the country’s national cyber defenses by covering more entities, like data centers and service providers, and requiring stricter incident reporting. These actions will help regulators better understand the evolving cyber threat landscape.
The EU’s European Action Plan on Healthcare Cybersecurity (2025) addresses cybersecurity in hospitals and healthcare providers by focusing on supply chain risks, offering cybersecurity support to organizations, and creating financial incentives for best practices.
Although these regulatory initiatives are crucial, there’s concern that they may encourage a checklist mentality, where organizations focus on meeting compliance requirements rather than fostering a cybersecurity culture. The real solution requires consistent investment in cybersecurity infrastructure and compliance within healthcare practices.
Key Takeaways for Healthcare Professionals
As healthcare professionals, it’s essential to understand that cybersecurity directly impacts patient safety. Here are the key takeaways:
- Cybersecurity is not just an IT issue: Cyber threats can disrupt patient care, delay treatments, and endanger lives. Understand that cybersecurity is a patient safety issue that demands your attention and involvement
- Report suspicious activity immediately: Stay vigilant for phishing attempts and unusual activity. Reporting these early can prevent larger incidents from escalating.
- Ensure cybersecurity training for all staff: Equip your team with the knowledge to recognize cyber threats and maintain data privacy.
- Know your “downtime” procedures: Be familiar with manual backup processes. Knowing how to operate without digital systems is crucial when systems are compromised.
- Advocate for a stronger cybersecurity culture: Advocate for continuous improvements in cybersecurity protocols. From network segmentation to device security, ensuring robust defenses is vital for smooth and safe healthcare delivery.
FAQs
Cybersecurity is critical in healthcare because cyberattacks can disrupt operations, expose sensitive patient data, and compromise patient safety. When systems like EHRs go down, clinicians may lose vital information needed for diagnosis and treatment.
Healthcare organizations are targeted due to the sensitive data they store, including medical records and insurance details. Legacy IT systems and interconnected medical devices make them more vulnerable to cyberattacks.
- Ransomware attacks
- Phishing emails
- Medical device vulnerabilities (IoMT)
- Supply chain risks
Cyberattacks can interrupt clinical workflows by blocking access to EHRs, lab results, imaging, and medication systems. This can delay treatment, increase the risk of errors, and force facilities to postpone procedures.
Healthcare professionals can improve cybersecurity by using strong passwords, enabling multi-factor authentication, and being cautious with emails. They should also participate in training and adhere to security protocols.
