Over the past few years, the Internet of Things (IoT), coupled with the ubiquitous nature of Information Technology, has resulted in an ever-expanding attack surface where rapid solution development and enhanced functionality routinely prevail over security. For example, attackers once disrupted most U.S. internet activity using 61 default IoT usernames and passwords. Consumers failed to change them before activating their devices, effectively turning our gadgets into culprits responsible for one of the largest Distributed Denial of Service (DDoS) in the world’s history.

The healthcare industry is rapidly adopting IoT devices (often called the Internet of Medical Things (IoMT)) to enhance patient safety and healthcare workers' treatment delivery. From medication administration to remote sensor monitoring, embedded medical devices are improving the quality of care and increasing interaction with their providers. While this technology was created with good intentions, the lack of security in product design phases is a major concern that will likely materialize into malicious action with grave consequences.

The consequences became clear in 2017 as researchers were able to acquire equipment (from $15 – $3,000) and intercept the radio frequencies from cardiac devices. With this capability, they could reprogram the devices to modify the patient’s heartbeat and drain the internal battery. As a result, the FDA recalled almost 500,000 pacemakers and enforced in-person firmware updates. Researchers have also demonstrated similar capabilities on infusion pumps and MRI systems.

Non-networked medical devices may be operating at a higher level of risk. Ease of access and the availability of RFID cloners contribute to a relatively weak physical security posture. In 2018, researchers demonstrated the capability to emulate and alter a patient’s vital signs in real-time using an electrocardiogram simulator they found on eBay for $100.

In late 2018, the Department of Health and Human Services Office of the Inspector General (IG) critiqued FDA procedures in assessing post-market cybersecurity risk to medical devices. To fortify 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 their ongoing efforts in enhancing 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.

Additionally, the lack of mandatory requirements and accountability in the past has contributed to the lax approach towards security in the industry. However, recent changes have brought about a much-needed shift in mindset. Introducing new regulations and the potential for costly fines for non-compliance have made it clear that the days of overlooking security are over.

The FDA's new cybersecurity regulations have been put in place to ensure the security of medical devices. Section 524B (c) of these regulations defines a device that falls within the scope of these requirements. According to this section, a device is considered to be within the regulations if it includes software that is validated, installed, or authorized by the sponsor of the device or within it. Additionally, the device must be able to connect to the internet and possess technological characteristics that have been validated, installed, or authorized by the sponsor. This definition highlights the potential vulnerability of these devices to cyber threats. The purpose of these regulations is to address these vulnerabilities and establish a higher level of accountability and responsibility among medical device manufacturers. By mandating compliance and introducing potentially costly fines for non-compliance, the FDA aims to ensure that these regulations have a tangible and meaningful impact on the security of medical devices. The focus on accountability signifies a shift from the previous voluntary compliance approach, making it clear that laxity in cybersecurity measures is no longer acceptable in the medical device industry.

Traditional cyber defense tools are not compatible with network connected medical devices for several reasons. Firstly, these devices often lack the necessary infrastructure to support the installation and operation of security tools. Unlike standard computers or mobile devices, medical devices have limited processing power, memory, and storage capacity. This makes it impractical, if not impossible, to run resource-intensive security software on such devices.

Additionally, applying any software modifications to these medical devices could be perceived as tampering and may potentially impact their compliance with regulations, specifically those set by the Food and Drug Administration (FDA). The FDA has emphasized the importance of manufacturers implementing adequate security measures, but restrictions on modifying devices make it challenging to enhance their security post-production.

Furthermore, traditional security tools are typically designed to protect more conventional systems and networks. They may not have been specifically developed or adapted to address the unique vulnerabilities and intricacies associated with medical devices. As a result, these tools may not effectively identify and mitigate the specific threats targeting medical devices, leaving them vulnerable to cyberattacks.

Given the critical nature of medical devices and the potential risks posed by cybersecurity breaches, it is important for manufacturers to integrate proper security tools directly into the design and production of these devices. This would ensure that they are secure from the outset and comply with FDA regulations.

Maintaining security within medical devices is the responsibility of manufacturers. The FDA emphasizes that manufacturers are required to stay diligent in identifying and addressing risks and hazards associated with their devices, including those related to cybersecurity. However, it is noted that not all manufacturers take this responsibility seriously.

The types of medical devices that are most vulnerable to hacking are stationary devices. While it is unsettling to contemplate the possibility of internally embedded medical devices being hacked and tampered with, it is important to note that the primary motivation for hackers is financial gain rather than terrorism. These cybercriminals primarily target stationary devices because they present the highest potential for stealing valuable patient data in large quantities.

Medjacking, also known as medical device hijacking, is a serious cybersecurity issue that puts healthcare organizations at risk. It involves hackers compromising networked medical devices, including consumer health monitoring devices, wearables, embedded devices, and stationary devices, which are all connected to the internet.

One of the primary reasons why medjacking poses a threat is the valuable patient health data that these devices contain. Stationary devices like medical x-ray scanners and chemotherapy dispensing stations are particularly vulnerable, as they hold sensitive information that cybercriminals can exploit. In fact, medical data carries a higher value in the black market compared to credit card data, making these devices an attractive target for hackers.

The main factor contributing to the vulnerabilities in medical devices is the lack of security prioritization from manufacturers. These devices often do not come with robust built-in security measures, making them easy targets for hackers. Furthermore, the use of cyber defense tools is limited when it comes to medical devices, exacerbating the security risks.

Making matters worse, the government has not taken strong action against manufacturers or enforced strict security measures to mitigate these risks. This lack of regulatory pressure leaves healthcare organizations more exposed to potential medjacking incidents.

Another challenge in addressing medjacking is the difficulty in patching and fixing vulnerabilities in devices that are constantly in use. Healthcare organizations rely on these devices for critical functions and may face logistical challenges in implementing necessary security updates.

The consequences of medjacking can be severe for healthcare organizations. They are at risk of violating HIPAA regulations, which can lead to legal and financial penalties.
