Examples of Hacked Medical Devices

Updated April 13, 2025

Medical devices have improved patient care, diagnosis, and treatment. But as these devices have become more connected and more dependent on software, they have also become attractive targets for attackers.

This post looks at medical devices that have been hacked or exposed, what that means for patients and providers, and why stronger cybersecurity controls are necessary across healthcare.

Understanding Medical Device Vulnerabilities

• Design Flaws: Historically, medical device development focused on functionality and patient safety, often with little attention to cybersecurity. That left many devices with built-in weaknesses.
• Outdated Software: Many medical devices run outdated operating systems or software that manufacturers no longer support. That makes them hard to secure and maintain because patches and updates may no longer be available.
• Interconnectivity: The growing connectivity of medical devices within healthcare networks and the Internet of Things (IoT) ecosystem gives attackers more entry points. One compromised device can put an entire network at risk.

Examples of Compromised Medical Devices

• Insulin Pumps: In 2019, security researchers discovered vulnerabilities in certain models of Medtronic insulin pumps. These flaws could let attackers manipulate insulin dosage, creating a life-threatening risk for diabetic patients.
• Cardiac Devices: In 2016, the U.S. Food and Drug Administration (FDA) warned about security vulnerabilities in St. Jude Medical’s cardiac devices, including pacemakers and defibrillators. These vulnerabilities could have allowed attackers to access and change device settings, putting patients’ lives at risk.
• Infusion Pumps: Infusion pumps, used to deliver medications and fluids, have also faced cybersecurity problems. In some cases, attackers could alter medication dosages, potentially causing harm or death.

The Consequences of Medical Device Compromise

• Compromised Patient Safety and Health Outcomes: Unauthorized access to or manipulation of medical devices can lead to incorrect diagnoses, inappropriate treatment decisions, and direct patient harm. The immediate danger is only part of the problem. Long-term outcomes can also worsen, with prolonged recovery, increased morbidity, or irreversible damage.

• Unauthorized Access and Exposure of Sensitive Data: Medical devices often store and transmit sensitive patient information. Cyberattacks can cause major data breaches, exposing health records, personal identification information, and financial data. That violates privacy laws and puts patients at risk of identity theft and fraud.

• Financial Implications for Healthcare Providers: A cybersecurity breach can create costs across several fronts. Response costs, legal fees, penalties for non-compliance with data protection regulations, and spending on stronger security measures add up fast. Providers may also face lawsuits from patients or insurers.

• Reputational Damage: Trust is central to healthcare. A cyberattack that compromises patient safety or data can damage the reputation of both healthcare providers and medical device manufacturers. Rebuilding trust takes time. A damaged reputation can also mean fewer patients, lost partnerships, and trouble hiring and retaining skilled staff.

• Regulatory and Legal Consequences: Healthcare providers and medical device manufacturers must meet strict requirements for patient data protection and device safety. Cybersecurity incidents can trigger regulatory scrutiny, fines, and sanctions. Failing to protect patient information can also lead to legal action from patients, regulators, and other parties.

• Impact on Innovation and Device Development: Concern about cybersecurity weaknesses can slow the development and adoption of new medical technologies. Manufacturers may delay releases, and providers may hesitate to adopt advanced tools, slowing progress in care delivery.

• Systemic Healthcare Disruptions: A coordinated cyberattack can affect more than a single device or system. Disabling devices in an intensive care unit or tampering with laboratory results could cause widespread confusion, treatment delays, and reduced efficiency across healthcare operations.

• Increased Insurance Costs: Cybersecurity incidents can raise premiums for cyber insurance, liability insurance, and related coverage for healthcare providers and medical device manufacturers. Those higher costs can strain budgets and pull money away from patient care or research and development.

Handling Consequences

To reduce these consequences, healthcare providers, medical device manufacturers, and regulators need to work together on stronger security measures, incident response plans, and ongoing cybersecurity training. Standards and guidelines such as ISO/IEC 27001 for information security management and the principles in “OWASP Security by Design Principles” provide a structured way to manage cybersecurity risk​.

Addressing the Urgent Issue

Protecting medical devices and sensitive health data takes a practical, multi-part approach. That means coordinated action across the healthcare ecosystem.

Enhanced Collaboration for Unified Cybersecurity Standards

• Multi-Stakeholder Cybersecurity Frameworks: Healthcare providers, device manufacturers, and regulators need to work together on cybersecurity frameworks. These frameworks should standardize security practices so devices and systems are more consistent and compatible.
• Industry-Government Partnerships: Partnerships between the healthcare industry and government agencies can improve sharing of cyber threat intelligence and strengthen collective response to cybersecurity threats.

Commitment to Regular Security Updates and Maintenance

• Mandatory Update Policies: Manufacturers must have policies that ensure medical devices get timely security updates and patches throughout their lifecycle.
• Automated Update Mechanisms: Where possible, automated update mechanisms can help keep devices current with the latest patches and reduce dependence on manual updates.

Comprehensive Education and Awareness Programs

• Cybersecurity Training for Healthcare Professionals: Healthcare professionals need training tailored to their environment. That training should cover threat recognition, cybersecurity best practices, and incident response procedures.
• Patient Education Initiatives: Patients should get clear, accessible information about the cybersecurity risks tied to their medical devices. That includes guidance on secure use and who to contact if they suspect a breach.

Prioritizing Secure Design from the Outset

• Embedding Security in the Design Process: Security needs to be part of the medical device design process from the start. That includes encryption for data at rest and in transit, strong authentication, and access controls that restrict functionality to authorized users.
• Adherence to Secure Development Lifecycles: Manufacturers should follow secure development lifecycle (SDL) practices, which build security into every phase of device development, from conception through decommissioning.

Implementing Continuous Monitoring and Rapid Response Systems

• Advanced Monitoring Solutions: Healthcare institutions should deploy monitoring and detection systems to identify suspicious activity or potential breaches in real time. This can include intrusion detection systems (IDS) and security information and event management (SIEM) systems.
• Proactive Incident Response Teams: Dedicated incident response teams need the tools and authority to act quickly during a cybersecurity incident. They should be trained in forensics, containment, and recovery to limit the damage.

The Role of Regulatory Bodies

Regulators such as the Food and Drug Administration (FDA) are central to medical device cybersecurity. Their job includes setting expectations, reducing risk, and protecting public health.

Expanding the Scope of Regulatory Oversight

• Development of Comprehensive Cybersecurity Frameworks: Regulatory bodies are responsible for creating cybersecurity frameworks that define requirements for designing, developing, and deploying medical devices. These frameworks should evolve with current research and threat intelligence.

• Guidance for Incorporating Cybersecurity in Device Design: By issuing detailed guidance on cybersecurity in device design, regulatory bodies help ensure security is built into product development. That includes recommendations for encryption, secure coding, and strong access controls.

• Mandatory Risk Assessment Protocols: Mandatory risk assessment protocols help ensure that manufacturers evaluate cybersecurity threats throughout the product lifecycle. That includes premarket assessments and continuous postmarket surveillance.

• Issuance of Warnings and Recall Authority: Regulatory bodies need authority to issue warnings about known vulnerabilities and, when needed, require recalls of devices that create significant patient safety risk.

Adapting Regulations for an Evolving Threat Landscape

• Dynamic Regulatory Frameworks: As cyber threats change, regulations need to change with them. Regulatory bodies should update guidance regularly to reflect new attack methods, advances in security technology, and changes in device use and connectivity.

• Strengthening Requirements for Device Manufacturers: Regulations should require manufacturers to implement stronger cybersecurity measures during development and maintenance. That includes regular software updates and patches, vulnerability scanning, and secure product lifecycle management.

• Accountability and Enforcement Mechanisms: Manufacturers need to be held accountable for meeting cybersecurity standards and regulations. That can include audits, penalties for non-compliance, and transparent reporting of cybersecurity incidents.

• Promotion of Industry Collaboration: Regulatory bodies can support information sharing and best practices across manufacturers, healthcare providers, and cybersecurity experts. Better collaboration improves overall medical device security and encourages better security solutions.

• Public Awareness and Education: Regulatory enforcement alone is not enough. Patients and healthcare providers also need education on the cybersecurity risks tied to medical devices. Regulatory bodies can help by raising awareness and publishing useful resources.

By taking on these roles and updating regulations as threats change, regulatory bodies such as the FDA can help keep medical devices safe and secure and protect patient health and personal data from cyberattacks.

Case Study: The Impact of the St. Jude Medical Cardiac Device Vulnerability

The cybersecurity vulnerabilities discovered in St. Jude Medical’s cardiac devices remain a key case study in medical device security. The vulnerabilities created a direct patient safety risk by potentially allowing unauthorized access to device controls. They also exposed major weaknesses in protecting sensitive patient data.

The FDA responded by warning the public and later recalling affected devices. That action reduced immediate risk and made clear that cybersecurity in medical devices is not optional. The incident forced a reexamination of existing cybersecurity practices and showed the need for a stronger framework to address these vulnerabilities.

After the St. Jude Medical incident, consensus grew around the need for closer coordination among healthcare providers, device manufacturers, and regulators. That coordination is necessary to develop and enforce stronger cybersecurity protocols, including regular security assessments, timely patches and updates, and clear communication with stakeholders about risk.

The incident also showed why cybersecurity needs to be addressed across the full device lifecycle, from design through postmarket surveillance. Security cannot be an afterthought.

The FDA’s warning and subsequent recall made the urgency clear. It was a wake-up call for healthcare providers, manufacturers, and regulators to put stricter cybersecurity protocols in place.

Conclusion

Medical devices have improved patient care, but they have also become targets for cyberattacks. Medical device hacking threatens patient safety, data security, and healthcare operations. Addressing it takes coordinated work from healthcare providers, manufacturers, regulators, and cybersecurity experts.

What are the security requirements that medical device applicants must now meet?

The U.S. Food and Drug Administration (FDA) has established specific cybersecurity requirements that medical device manufacturers must meet. These include:

1. Secure Product Development Lifecycle: Manufacturers are required to implement a secure product development lifecycle. This means reducing the number and severity of vulnerabilities across the full lifecycle of their devices, from design and development to distribution, deployment, and maintenance​.

2. Threat Modeling and Post-Market Vulnerability Management: Manufacturers must conduct threat modeling and describe plans for addressing post-market vulnerabilities. This includes patching and software updates to respond to potential security issues​​​.

3. Coordinated Disclosure of Exploits and Software Bill of Materials: Details of the methods for coordinated disclosure of exploits must be included. Manufacturers must also provide a software bill of materials (SBOM) that lists all third-party commercial, open-source, and off-the-shelf software components used in their devices​​​.

4. Process and Procedures for Postmarket Updates and Patches: Companies must describe the processes and procedures for releasing postmarket updates and patches that address security issues. This includes regular updates and out-of-band patches for critical vulnerabilities​​.

These requirements apply to "cyber devices," defined as devices that run software, can connect to the internet, and could be vulnerable to cyber threats. As of October 1, 2023, the FDA's refuse-to-accept policy applies to premarket submissions that lack the required cybersecurity information​​​​.

Medical device manufacturers should review the FDA's updated guidance document, "Cybersecurity in Medical Devices: Quality System Considerations and Content of Premarket Submissions," to make sure their products meet the required cybersecurity standards. Failure to meet these requirements could result in the FDA rejecting premarket submissions​​.

What new policy has the FDA announced for medical device manufacturers?

According to the recent announcement by the FDA, medical device manufacturers are now required to follow a new cybersecurity policy. Under this policy, all new applicants for medical devices must submit a comprehensive plan that explains how they will actively monitor, identify, and address potential cybersecurity issues. This plan must also include steps to ensure that the device is adequately protected.

In addition, the FDA now requires applicants to establish a reliable process that reasonably assures the device's security. This includes taking the necessary measures to make security updates and patches available regularly and in critical situations. Applicants must also provide the FDA with a detailed software bill of materials that includes any open-source or other software used in their devices.

Overall, this policy emphasizes the importance of cybersecurity in medical devices and is intended to ensure that manufacturers take appropriate measures to protect patient safety and guard against cyber threats.

What is Blue Goat's methodology for medical device cybersecurity assessment for FDA compliance?

Blue Goat uses a two-step Assessment Evolution test/retest approach for optimal outcomes. Within each Evolution, in addition to the medical device assessment and testing components, we dedicate access to our cybersecurity team for report clarification and knowledge exchange, helping you understand the findings and remediation strategies.

After remediation of Evolution 1, we conduct the cybersecurity assessment and penetration test again to assess how effectively the identified vulnerabilities were addressed. This second set of reporting demonstrates a stronger security posture and, therefore, a more impactful Letter of Attestation.

Our overall medical device security assessment and testing process involves four high-level phases:

1. Discovery
2. Security Boundary Definition
3. Security Risk Assessment
4. Mitigation Strategy

Medical Device Assessment Evolution 1

1. Preparation (Offsite). Before we travel to your facility, we prepare for the onsite visit. Our preparation consists of Discovery, such as reviewing the following:

• Design documents
• Data flow diagrams
• Use cases
• Traceability matrix
• Security architecture
• User manuals
• Admin/maintenance manuals
• Installation procedures and guidance
• Risk assessment
• Hazard analysis
• Source code
• Total Product Life Cycle (TPLC) documentation
• Product photos
• Any other relevant device documentation

We get familiar with your product, build a plan of action, and develop the Test Plan and Test Cass before the onsite visit. This helps us use our onsite time efficiently.

2. T esting (Onsite or at Blue Goat's facility). We travel to your facility to perform the cybersecurity assessment and penetration test against your medical device/system. Testing can also be done at Blue Goat’s facility if you ship the equipment to us. Our testing includes identifying all entry points into the system, such as Ethernet, Fiber, WiFi, USB, BTLE, Serial, and HDMI. We assess vulnerabilities tied to each entry point and the exploitation of initial and subsequent vulnerabilities. Any critical findings discovered will be brought to your attention immediately. Because of the nature of our engagement, we can also share daily end-of-day test updates.

3. Reporting (Offsite). At the end of testing, we generate a medical device cybersecurity assessment and penetration test report that ranks findings by criticality. The report includes step-by-step exploitation details with screenshots. It also includes remediation guidance for each finding.

4. Report Presentation (Offsite). Once the report is completed, we securely send it to you and review it with you over Zoom.

Between Evolution 1 and Evolution 2, you will work on fixing issues identified in Evolution 1.

Medical Device Assessment Evolution 2​

When you are ready for us to retest the medical device, we repeat the applicable steps from Evolution 1 in Evolution 2. This is completed onsite at Blue Goat or at your facility.

At the end of Evolution 2, we generate a Letter of Attestation that summarizes the medical device's scope, findings, and overall risk rating. The Letter of Attestation is intended to be shared with clients, auditors, regulators, and others.

What is the goal of a penetration test against a medical device?

Blue Goat understands the importance of securing wired and wireless medical devices and protecting your business from cybercriminals. We assess the cybersecurity posture of your devices to identify vulnerabilities and weaknesses in their networks and infrastructure. By conducting a thorough penetration test, we help protect patients and reduce organizational risk.

During the penetration test, our team evaluates the security defenses of your medical devices and looks for potential entry points for cyberattacks. We examine hardware, software, peripherals, and all other input/output systems. Our experts fuzz, analyze, and test each area for flaws that could compromise patient care or device integrity.

We also focus on common vulnerabilities and exposures (CVEs) seen in the medical device space. That includes attempts to bypass kiosked applications running on these devices to determine whether unauthorized access to the underlying operating system is possible. This work often takes hours or days to uncover a chain of flaws that would make such a bypass possible.

We also examine the physical aspects of the device. That includes looking for alternate ports such as JTAG, UART, or other unprotected ports, additional USB ports, and accessible hard drives.

Beyond that, we conduct forensics and post-exploitation movements, detonating payloads, pivoting, and adjusting operating systems to simulate real-world scenarios that could affect patient care. We also reverse engineer proprietary binaries and programs, searching for sensitive keys to determine whether encryption uses static or dynamically created keys.

This penetration test gives you a full view of your medical device's security weaknesses and vulnerabilities. Based on the findings, we provide detailed recommendations for patching and strengthening defenses, helping improve patient safety and reduce organizational risk.

What is AAMI TIR57?

AAMI TIR57 is a technical information report focused on principles for medical device security risk management. It comes from the Association for the Advancement of Medical Instrumentation (AAMI), an organization known for its work in medical devices.

Overview

AAMI TIR57, titled "Principles for medical device security-Risk management," provides a structured approach to managing cybersecurity risks in medical devices. This matters because medical devices, like other connected technology, can be vulnerable to cyber threats. The report gives guidance on security measures across a device's lifecycle, from design and development to decommissioning.

The "Why"

TIR57 matters because it focuses on patient safety and data security. As medical devices become more connected and rely more on software, they become more exposed to cyber threats. Those threats can affect device functionality and lead to patient harm. TIR57 helps manufacturers and healthcare providers reduce these risks by setting sound security practices.

Examples and Case Studies

Consider a hospital using networked medical devices such as heart rate monitors or insulin pumps. These devices are essential to patient care. If they are hacked because of weak security, the result could be anything from a data breach to a life-threatening event. Applying the principles of AAMI TIR57, such as performing risk assessments and building cybersecurity into device design, helps prevent those outcomes.

For Blue Goat Cyber, understanding and applying AAMI TIR57 means offering services that align with those standards. That includes conducting risk assessments, advising on secure device design, and providing ongoing security support.

Connecting the Dots

In this field, AAMI TIR57 is more than a guideline. It is a framework for improving the security and safety of medical devices, which is a core part of healthcare cybersecurity. By applying these principles in your services, Blue Goat Cyber positions itself as a knowledgeable provider of medical device security.

Understanding and applying AAMI TIR57 can also help when speaking with cybersecurity decision-makers in healthcare. They need partners who understand both the technical side of cybersecurity and the specific challenges tied to medical devices. Expertise in this area is a real differentiator.

What is a Cybersecurity Bill of Materials (CBOM)?

A Cybersecurity Bill of Materials (CBOM) is a requirement enforced by the FDA from March 29, 2023, onward for medical devices. It requires medical device manufacturers to provide a complete and accurate list of software and hardware components used in their devices, including third-party software and open source components. This list, known as the CBOM, serves as a self-attestation by manufacturers about the accuracy and completeness of those components. One key part of the CBOM is the inclusion of a Software Bill of Materials (SBOM), which provides transparency into the software components used in medical devices. Because medical devices are critical systems with real cybersecurity risk, a complete and accurate SBOM is especially important for maintaining device security and integrity.

How can Blue Goat help in generating accurate SBOMs?

Blue Goat has provided reliable and precise Software Bill of Materials (SBOMs) for clients for more than ten years. We have developed tools that can identify components accurately, even at the snippet level. Using advanced string search algorithms, we can detect third-party and commercial components effectively. Blue Goat also offers an SBOM-as-a-service solution that delivers complete and accurate SBOMs in standard formats such as SPDX and CDX that comply with FDA requirements. In addition, Blue Goat can validate internally generated SBOMs or those created by software supply chain partners to ensure they align with FDA regulations. By using our expertise and tools, Blue Goat helps organizations generate reliable and accurate SBOMs.

What's the difference in a CBOM and SBOM?

The terms "Cybersecurity Bill of Materials" (CBOM) and "Software Bill of Materials" (SBOM) are related concepts in cybersecurity and software management. The main difference is scope and focus:

1. Software Bill of Materials (SBOM): An SBOM is a detailed inventory of all components, libraries, and modules that make up a piece of software, including open-source and proprietary elements. Its purpose is to give users such as end-users, developers, and security professionals a clear understanding of what software is running in their environment. This supports vulnerability management, license management, and security analysis.

2. Cybersecurity Bill of Materials (CBOM): A CBOM extends the SBOM concept by including not only software components but also hardware components, network dependencies, and other elements needed to understand the cybersecurity posture of a device or system. A CBOM is especially relevant when the security of the entire ecosystem, including physical components and network interactions, matters. In medical devices or industrial control systems, for example, that broader view helps assess vulnerabilities, attack paths, and overall system security.

In short, an SBOM focuses on software components, while a CBOM provides a broader view of all cybersecurity-relevant elements. Both improve transparency and support better risk management.

What is the significance of SBOMs and SPDX in the present and future?

March 29, 2023, marked a major milestone as the FDA began enforcing cybersecurity requirements for medical devices and pushing manufacturers to comply with a Cybersecurity Bill of Materials (CBOM). A key part of the CBOM is the Software Bill of Materials (SBOM), which lists the software and hardware components used within medical devices. That includes internally developed software as well as third-party and open-source components.

SBOMs matter because they improve transparency and accountability in the medical device supply chain. By requiring manufacturers to self-attest to the accuracy of their SBOMs, regulators get a clearer view of the components used in device production. That supports better assessment and management of potential vulnerabilities.

One recognized standard for SBOMs is the Software Package Data Exchange (SPDX) format. SPDX provides a consistent way to document and share SBOMs, which helps manufacturers, regulators, healthcare providers, and consumers communicate more efficiently. This standardization supports interoperability and makes SBOMs easier to compare and analyze.

SBOMs and SPDX matter now and will matter even more going forward because they strengthen cybersecurity practices and improve transparency across industries, not just healthcare. As noted by the National Telecommunications and Information Administration (NTIA), SBOM implementation should extend beyond medical devices and become common practice in other sectors as well. That reflects broader recognition that organizations need to understand and manage the software components inside connected systems.

With SBOM requirements now being enforced, companies across industries are working to produce compliant SBOMs, and some are turning to third-party providers that specialize in generating accurate and complete SBOMs. These providers, such as Synopsys, offer tools that can precisely identify software components, including third-party and commercial elements, and help ensure the resulting SBOMs align with the requirements set by regulators such as the FDA.

What are the additional elements required by the FDA for an SBOM?

The FDA has established additional requirements for a Software Bill of Materials (SBOM) for medical devices. In addition to the minimum elements defined by the National Telecommunications and Information Administration (NTIA), the FDA requires specific additional information. These elements include the support level, support end date, and known security vulnerabilities of the software components used in medical devices.

While open source projects may not have designated support levels or support end dates, these added elements largely apply to third-party or commercial components integrated into the medical device application. Complete and accurate SBOMs are critical because they improve transparency and keep attention on cybersecurity.

What tools does Blue Goat use for testing software for medical devices?

Blue Goat Cyber uses a combination of Static Application Security Testing (SAST) and Dynamic Application Security Testing (DAST) for medical device software testing. SAST analyzes source code to identify vulnerabilities, while DAST tests the running application to find security issues. Both methods are important for securing medical devices, which handle sensitive data and are subject to strict FDA regulations and HIPAA guidelines. Blue Goat Cyber's approach addresses concerns specific to medical devices, including compliance with changing security standards and protection of critical patient information.

In addition to SAST and DAST, Blue Goat Cyber also uses penetration testing and vulnerability assessment tools for broader medical device software testing. Penetration testing tools simulate real-world cyberattacks to identify potential breaches, while vulnerability testing tools scan for known issues. Together, these methods provide a strong framework for security and compliance, addressing challenges such as critical functionality, data sensitivity, and regulatory standards like FDA clearance and HIPAA compliance​.

What is some background on medical device vulnerabilities?

Over the past few years, the Internet of Things (IoT), combined with the spread of Information Technology, has created a growing attack surface where fast development and added functionality often win out over security. For example, attackers once disrupted most U.S. internet activity using 61 default IoT usernames and passwords. Consumers did not change them before activating their devices, which helped fuel one of the largest Distributed Denial of Service (DDoS) attacks in history.

The healthcare industry is rapidly adopting IoT devices, often called the Internet of Medical Things (IoMT), to improve patient safety and care delivery. From medication administration to remote sensor monitoring, embedded medical devices are improving care quality and increasing interaction with providers. But weak security during product design remains a major problem that can lead to serious malicious activity.

The consequences became clear in 2017 when researchers acquired equipment costing from $15 - $3,000 and intercepted the radio frequencies from cardiac devices. With that capability, they could reprogram the devices to change a patient’s heartbeat and drain the internal battery. As a result, the FDA recalled almost 500,000 pacemakers and required in-person firmware updates. Researchers have shown similar capabilities on infusion pumps and MRI systems.

Non-networked medical devices may carry even higher risk. Ease of access and the availability of RFID cloners contribute to weak physical security. In 2018, researchers demonstrated the ability to emulate and alter a patient’s vital signs in real time using an electrocardiogram simulator purchased on eBay for $100.

In late 2018, the Department of Health and Human Services Office of the Inspector General (IG) criticized FDA procedures for assessing postmarket cybersecurity risk in medical devices. To strengthen the FDA's core mission “to ensure there is a reasonable assurance that medical devices legally marketed in the United States are safe and effective for their intended uses,” they outlined ongoing efforts to improve medical device security.

According to the FDA, “Healthcare Delivery Organizations (HDOs) are responsible for implementing devices on their networks and may need to patch or change devices and/or supporting infrastructure to reduce security risks. Recognizing that changes require a risk assessment, the FDA recommends working closely with medical device manufacturers to communicate necessary changes.”

Blue Goat can help HDOs transfer that risk by evaluating the cybersecurity posture on your wired or wireless medical devices.

What are some reasons for the lack of security in many medical devices?

The lack of security in many medical devices comes from several factors. One major factor is the increased scrutiny on these vulnerabilities, which forced regulators such as the FDA to reassess cybersecurity requirements. An FBI report found that 53% of digital medical devices and internet-connected products had critical vulnerabilities, exposing patients and providers to serious security risks. Many of these vulnerabilities were found in unpatched and outdated devices. Research also suggests that 88% of healthcare cyberattacks involved an IoMT device, which shows how urgent the problem is.

Weak security controls have been a long-standing issue. Many devices were designed mainly around medical function, with security added later, if it was added at all. These bolted-on controls have often been inadequate, leaving weaknesses that attackers can exploit. In the past, the lack of mandatory requirements and accountability also contributed to the weak security posture. That has started to change. New regulations and the possibility of costly fines for non-compliance have made it clear that ignoring security is no longer acceptable.

What is the purpose of the new cybersecurity regulations implemented by the FDA?

The FDA's new cybersecurity regulations are intended to improve the security of medical devices. Section 524B (c) of these regulations defines which devices fall within scope. Under this section, a device falls under the regulations if it includes software that is validated, installed, or authorized by the sponsor of the device or within it. The device must also be able to connect to the internet and have technological characteristics that have been validated, installed, or authorized by the sponsor. This definition reflects the fact that these devices can be vulnerable to cyber threats.

The purpose of these regulations is to address those vulnerabilities and create more accountability for medical device manufacturers. By requiring compliance and introducing potentially costly fines for non-compliance, the FDA aims to make these regulations have a real effect on medical device security. The focus on accountability marks a shift away from the earlier voluntary-compliance approach and makes clear that weak cybersecurity practices are no longer acceptable in the medical device industry.

What is the FDA's new requirement for connected medical devices?

The FDA introduced a new requirement for connected medical devices that took effect on March 29, 2023. This requirement focuses on cybersecurity and is intended to improve device safety and security. One part of this requirement is the implementation of a Cybersecurity Bill of Materials (CBOM).

Under the CBOM, manufacturers of medical devices must attest to the accuracy of a complete list of software and hardware components used in their devices. This list must include components developed by the manufacturer as well as any third-party software and open-source components built into the device.

The FDA specifically emphasizes the importance of a Software Bill of Materials (SBOM) within the CBOM framework. An SBOM is important for connected medical devices because it provides a complete and accurate inventory of all software components used. That makes it easier to track vulnerabilities and respond to possible cybersecurity incidents.

By enforcing this requirement, the FDA aims to ensure that manufacturers prioritize cybersecurity in the development and maintenance of connected medical devices. The goal is to improve the overall safety and security of these devices for healthcare professionals and patients.

How can cybersecurity vulnerabilities in medical devices lead to patient data breaches?

Patient Monitors: Devices that monitor vital signs such as heart rate and blood pressure can be vulnerable to data interception and manipulation, creating serious risk to patient data security. Attackers can exploit these weaknesses to intercept or alter collected data. That can lead to misdiagnosis or delayed treatment and put patients at risk.

MRI Machines: MRI machines are critical diagnostic tools, but they are not immune to cybersecurity threats. Attacks against these systems can disrupt operation, potentially causing incorrect imaging data or full operational failure. That can affect diagnostic accuracy and treatment planning.

Radiation Therapy Systems: Hacking radiation therapy systems creates serious patient safety risk. These systems are used in cancer treatment, and unauthorized access to their controls can lead to incorrect radiation doses. That could mean too little radiation for effective treatment or dangerously high doses that cause harm.

Diagnostic and Imaging Equipment: Equipment such as CT scanners and ultrasound machines can also be compromised. If attackers manipulate these devices, they may produce false diagnostic information, leading to wrong treatment decisions, delayed care, or unnecessary procedures.

Surgical Robots: Surgical robots enable minimally invasive procedures, but they rely on precise controls. Unauthorized access or manipulation can cause loss of control or altered movements during surgery, creating the risk of surgical error and patient harm.

Defibrillators: External defibrillators are critical emergency devices, but they can also have cybersecurity vulnerabilities. In an attack, these devices could be compromised to disrupt lifesaving shocks or drain batteries, making them useless at critical moments.

Hospital Networking Equipment: Hospital networks are essential for the operation of connected medical devices even if they are not directly involved in patient care. A network breach can cause device dysfunction and loss of critical patient data. Because healthcare systems are interconnected, an attack on networking equipment can disrupt a much larger part of the environment.

These examples show why healthcare needs stronger cybersecurity safeguards. Up-to-date software, encryption, and strong password controls are necessary to protect patient data and keep medical devices operating safely.

What are the consequences of cyberattacks on medical devices?

Cyberattacks on medical devices can have serious consequences for patient safety and healthcare institutions. Direct interference with device operations can lead to incorrect treatment and severe health risks. These breaches create immediate danger and also undermine confidence in medical devices and healthcare institutions.

Recovery can be expensive and time-consuming. It may involve device recalls, software upgrades, and legal consequences. Those steps are necessary to address exploited vulnerabilities and prevent future breaches. Healthcare institutions need to invest in strong cybersecurity measures to protect networked medical devices and patient health.

There is also the risk that attackers could gain remote control of medical devices. That kind of access could let them change device settings, administer incorrect medication doses, or disrupt life-support equipment. These actions can be life-threatening, which is why stronger cybersecurity measures are necessary.

The medical field needs to treat the security of networked medical devices as a core safety issue. Reducing cyber risk, protecting device integrity, and maintaining patient trust all depend on it.

What are networked medical devices and why is cybersecurity important for them?

Networked medical devices are interconnected devices used in healthcare environments that rely on wireless technologies. They include insulin pumps, pacemakers, infusion pumps, patient monitors, MRI machines, and more. These devices help doctors and healthcare professionals monitor and manage patients remotely and support efficient, minimally invasive care.

But as these devices become more interconnected, the cybersecurity risk grows. If networked medical devices are compromised, attackers can use them in ways that seriously threaten patient safety, including severe harm or death. Several high-profile incidents have made that risk clear.

For example, insulin pumps have been manipulated remotely, exposing patients to insulin overdose risk. Pacemakers, which regulate heart rhythms, have had vulnerabilities that attackers could use to alter rhythms or drain batteries. The WannaCry ransomware attack on the UK's National Health Service also showed how attacks on hospital networks can indirectly affect patient care and safety.

These examples show why stronger security protocols, regular software updates, and close monitoring are necessary. Healthcare providers need those controls to protect patients and preserve the reliability of these devices.

What recommendations are given to prevent medjacking and secure networked devices?

To prevent medjacking and improve the security of networked devices, the following recommendations are provided:

1. Promptly address existing devices: Take immediate action to remediate any potential infections on your networked devices.

2. Swiftly implement software/hardware fixes: Build a plan to integrate and deploy the updates and fixes provided by medical device manufacturers as efficiently as possible.

3. Seek expert consultation: Engage competent HIPAA consultants to review your compliance program and provide onsite guidance. If needed, request a quote for a full HIPAA audit.

4. Prioritize cybersecurity-minded vendors: Evaluate medical device vendors based on their commitment to cybersecurity. Choose vendors that let you modify passwords, provide regular updates, and are willing to conduct quarterly reviews with you.

5. Manage device access: Implement strict access control measures, especially through USB ports. Consider using one-way memory sticks to prevent infections from spreading among similar devices.

6. Establish secure network zones: Isolate devices in dedicated, secure network zones. Add protection with an internal firewall that permits access only to specific services and authorized IP addresses.

7. Address end-of-life for medical devices: Regularly assess the effectiveness and support status of your medical devices. Dispose of devices that are no longer supported by manufacturers or cannot handle malware effectively. Before disposal, securely wipe or destroy any stored patient data.

Following these recommendations can significantly reduce medjacking risk and improve the security of networked devices.

Why don't traditional cyber defense tools work with medical devices?

Traditional cyber defense tools are often not compatible with network-connected medical devices for several reasons. First, these devices usually do not have the infrastructure needed to support the installation and operation of security tools. Unlike standard computers or mobile devices, medical devices often have limited processing power, memory, and storage. That makes it impractical or impossible to run resource-heavy security software on them.

Also, applying software modifications to medical devices can be seen as tampering and may affect regulatory compliance, especially with requirements set by the FDA. The FDA has stressed the importance of adequate security measures, but restrictions on modifying devices make post-production security improvements difficult.

Traditional security tools are also generally built for conventional systems and networks. They may not be designed for the unique vulnerabilities and technical characteristics of medical devices. As a result, they may fail to detect or mitigate threats that specifically target medical devices.

Because medical devices are critical systems and cybersecurity failures can have severe consequences, manufacturers need to build proper security controls directly into the design and production of these devices. That gives them a better chance of being secure from the start and staying aligned with FDA requirements.

Who is responsible for maintaining security within medical devices?

Manufacturers are responsible for maintaining security within medical devices. the FDA emphasizes that manufacturers must remain diligent in identifying and addressing risks and hazards associated with their devices, including cybersecurity-related risks. However, not all manufacturers take that responsibility seriously.

What types of medical devices are at the highest risk of being hacked?

The medical devices most vulnerable to hacking are stationary devices. While the idea of internally embedded medical devices being hacked is unsettling, attackers are usually motivated by financial gain rather than terrorism. They often target stationary devices because those systems offer the greatest potential for stealing large volumes of valuable patient data.

What is medjacking and how does it pose a threat to healthcare organizations?

Medjacking, or medical device hijacking, is a serious cybersecurity problem that puts healthcare organizations at risk. It involves attackers compromising networked medical devices, including consumer health monitoring devices, wearables, embedded devices, and stationary devices connected to the internet.

One reason medjacking is such a threat is the value of the patient health data these devices hold. Stationary devices such as medical x-ray scanners and chemotherapy dispensing stations are especially attractive targets because they store sensitive information that cybercriminals can exploit. Medical data often commands a higher price on the black market than credit card data.

A main reason for these vulnerabilities is that many manufacturers have not prioritized security. These devices often ship without strong built-in protections, making them easy targets. The limited ability to use traditional cyber defense tools on medical devices makes the problem worse.

The lack of strong regulatory enforcement has also increased exposure for healthcare organizations. Another challenge is that patching vulnerabilities in devices that are constantly in use can be difficult from an operational standpoint.

The consequences of medjacking can be severe. Healthcare organizations may violate HIPAA requirements, face legal and financial penalties, and suffer data breaches that compromise patient confidentiality.

To address medjacking, healthcare organizations should take proactive steps. That includes remediating infected devices, getting fixes and updates from manufacturers, consulting HIPAA experts, evaluating vendors based on cybersecurity maturity, controlling device access, isolating devices in secure network zones, and disposing of outdated devices properly.

What is medical device software testing?

Medical device software testing is the process of making sure software embedded in or used to control medical devices functions correctly, reliably, and in compliance with regulatory standards. This testing verifies that the software meets its intended functionality, user interface, integration, and performance requirements under regulations such as the FDA's 21 CFR Part 11 and the internationally recognized IEC 62304 standard. The goal is broad: remove defects in software architecture and code, meet strict compliance requirements, and help produce safe medical devices.

Key components of medical device software testing include:

• Functional Testing: This evaluates whether the software performs its intended functions correctly.
• Device Verification Testing: This verifies that the device as a whole, including its software, meets all specified requirements.
• Security Testing: Because medical data is sensitive and cybersecurity threats can directly affect safety, testing for security vulnerabilities is essential.
• Interoperability Testing: This ensures the device operates safely and compatibly with other systems or devices.
• Usability Testing: This focuses on human-device interaction and whether intended users can use the device efficiently, effectively, and satisfactorily.
• Performance Testing: This assesses stability, speed, and scalability under different conditions.
• Compliance Testing: This confirms that the software meets applicable regulatory and industry standards tied to safety, quality, and reliability.

Medical device software testing follows a rigorous methodology that includes planning, requirement analysis, test case development, test execution, and thorough documentation throughout the testing cycle. The purpose is to identify and fix defects or anomalies before the device reaches the market, helping ensure safety and efficacy. The process combines automated and manual testing and requires strong technical and regulatory knowledge.

What are common medical device vulnerabilities?

Common medical device vulnerabilities include a range of issues that can compromise safety, privacy, and effectiveness. These weaknesses are often tied to software flaws, outdated operating systems, or insecure interfaces that attackers can exploit to gain unauthorized access, steal sensitive data, or disrupt device function. Common examples include:

• Insecure Network Connections: Many medical devices connect to healthcare networks through Wi-Fi or Bluetooth, making them vulnerable to eavesdropping or unauthorized access if not properly secured.
• Outdated Software and Firmware: Devices running outdated software or firmware are exposed to known exploits that have not been patched. This includes operating systems no longer supported by vendors.
• Weak Authentication and Authorization Controls: Poor authentication can allow unauthorized users to access medical devices and alter critical healthcare information.
• Lack of Encryption: Failure to encrypt sensitive data at rest and in transit can expose patient health information (PHI) and other confidential data to interception and misuse.
• Third-Party Software Components: Vulnerable third-party software components can introduce additional risk, especially when manufacturers do not regularly update or patch them.
• Configuration and Customization Errors: Improper configuration or customization can leave devices open to attack. Examples include unchanged default passwords or disabled security features.
• Physical Security: Physical access to devices can also be a threat if devices are not secured within the healthcare facility, allowing tampering or theft.

Addressing these vulnerabilities requires a clear cybersecurity strategy that includes regular updates and patches, strong encryption, strong authentication and authorization controls, and close monitoring of network connections. It also requires coordination between manufacturers, healthcare providers, and cybersecurity professionals to protect medical devices against new threats.
