The Hidden Risks: How Vulnerable Medical Devices Threaten Healthcare Security

The Growing Security Crisis in Healthcare

A shocking new report from Claroty reveals a critical cybersecurity threat facing hospitals and healthcare facilities. According to the State of CPS Security: Healthcare Exposures 2025 report, published on March 26, an overwhelming 89% of healthcare organizations are using highly vulnerable smart medical devices—also known as Internet-of-Medical-Things (IoMT) devices. These devices are not only exposed to the internet but also contain security weaknesses that cybercriminals actively exploit in ransomware attacks.

The report highlights the alarming extent of the problem:

99% of healthcare organizations have at least some IoMT devices with known vulnerabilities.
9% of all IoMT devices currently in use are vulnerable to cyberattacks.
20% of hospital information systems (HIS) are directly connected to these risky devices.
8% of medical imaging systems (X-rays, CT scans, MRIs, and ultrasound machines) are also linked to these vulnerable devices.
1,763 operational technology (OT) devices—such as those controlling hospital infrastructure—are both exposed online and known to contain critical security flaws.

Hospitals are rapidly embracing digital transformation, but at what cost? Security concerns are mounting as cybercriminals increasingly target these weaknesses, endangering patient safety and operational stability.

Expert Insights: The Need for Stronger Cybersecurity Measures

Ty Greenhalgh, Industry Principal for Healthcare at Claroty, warns that hospitals must balance their push for digital transformation with robust security measures. He urges healthcare security leaders to adopt an exposure-centric approach. This means prioritizing the most severe vulnerabilities and following established industry standards—such as the HHS’ HPH Cyber Performance Goals—to safeguard patient data and ensure uninterrupted medical care.

The report is based on an extensive analysis of 2.5 million IoMT devices and 647,000 operational technology devices across 351 healthcare organizations, making it one of the most comprehensive studies on this issue to date.

The Silent Threat Lurking in Hospitals

This report underscores a disturbing reality: hospitals are increasingly dependent on smart medical devices, but security measures have not kept pace. The findings reveal a widespread failure to secure critical healthcare infrastructure, exposing millions of patients to potential cyber threats.

Why Are These Medical Devices So Vulnerable?

Aging Infrastructure – Many hospital systems still use outdated software and hardware that lack modern security protections.
Lack of Standardized Security Protocols – Unlike traditional IT systems, medical devices often operate with inconsistent security measures, making them easy targets.
Internet Exposure – A significant number of these devices are directly connected to the internet, allowing cybercriminals to exploit vulnerabilities remotely.
Interconnected Systems – Vulnerable devices are often linked to hospital networks, allowing attackers to move laterally and compromise critical medical operations.

The Consequences of Ignoring This Issue

Patient Safety at Risk – Hackers can disrupt life-saving treatments, tamper with diagnostic equipment, or even shut down essential hospital systems.
Financial Damage – Ransomware attacks on hospitals can result in millions of dollars in recovery costs and lost revenue.
Data Breaches – Medical records contain highly sensitive personal information, making them valuable targets for cybercriminals.

A Call to Action: What Hospitals Must Do Now

Hospitals and healthcare providers must take proactive steps to address these vulnerabilities before a catastrophic cyberattack occurs. Some key measures include:

Implementing Continuous Security Monitoring – Real-time threat detection can help identify and mitigate risks before they escalate.
Upgrading Legacy Systems – Replacing outdated devices with modern, secure alternatives should be a top priority.
Following Industry Standards – Adhering to cybersecurity frameworks, such as the HPH Cyber Performance Goals, will enhance overall security.
Segmenting Networks – Isolating medical devices from the main hospital network can prevent malware from spreading.
Educating Healthcare Staff – Human error is a major factor in cyberattacks; ongoing cybersecurity training can reduce risks.

The Future of Healthcare Cybersecurity

With 99% of healthcare organizations affected by vulnerable devices, the industry is at a breaking point. Without urgent action, hospitals will remain prime targets for cybercriminals. However, by investing in stronger cybersecurity infrastructure and enforcing stricter security protocols, healthcare providers can protect both their patients and their operations from future threats.

Fact Checker Results:

✔ Widespread Device Vulnerability – The report confirms that nearly all healthcare organizations have security flaws in their medical devices.
✔ Ransomware Risks Are Real – Evidence shows that cybercriminals actively exploit these weaknesses, posing a significant threat.
✔ Urgent Action Needed – Experts agree that hospitals must adopt a proactive security approach to prevent further breaches.
