A recent study conducted by cybersecurity firm Eclypsium has revealed a critical security flaw in the firmware of the Illumina iSeq 100, a popular medical device used in healthcare settings. The flaw lies in the fact that Secure Boot, a security feature that cryptographically verifies the code responsible for booting the operating system, is not enabled on the device. This oversight leaves the device vulnerable to potential malware attacks, specifically a type known as a bootkit or boot rootkit, where malicious code can be injected into the boot process to gain control of the operating system kernel.
This revelation is particularly alarming given the prevalence of UEFI bootkits in the cybersecurity landscape. Over the past decade, various types of bootkits such as LoJax, MosaicRegressor, FinSpy, ESPecter, MoonBounce, CosmicStrand, and BlackLotus have been identified in the wild, posing serious threats to the security of systems and data.
Eclypsium’s research, although focused on the Illumina iSeq 100, highlights a more significant issue within the healthcare industry. The researchers believe that many medical devices, not just the Illumina iSeq 100, may harbor similar firmware security vulnerabilities that stem from the hardware supply chain. Unlike other industries, medical device vendors often outsource the development of hardware components to Original Design Manufacturers (ODMs) and Independent Biosimilar Vendors (IBVs), relying on them to ensure the security and integrity of the devices they produce.
This outsourcing of hardware development can create a gap in oversight and accountability when it comes to security practices. In the case of the Illumina iSeq 100, the lack of Secure Boot enabled on the device exposes it to potential cyber threats that could compromise patient data and the overall functionality of the device.
The implications of this security flaw extend beyond just the Illumina iSeq 100. It raises concerns about the broader cybersecurity posture of medical devices and the healthcare industry as a whole. With patient safety and sensitive data at stake, ensuring the security of medical devices is paramount in today’s interconnected and digital healthcare ecosystem.
In response to the findings, Eclypsium has urged medical device manufacturers to prioritize firmware security in their products and work closely with their supply chain partners to address any vulnerabilities that may exist. Proactive measures such as enabling Secure Boot and implementing robust security practices can help mitigate the risks associated with firmware-based attacks and protect the integrity of medical devices in healthcare environments.
As the healthcare industry continues to rely on interconnected technologies to deliver quality care and services, addressing cybersecurity challenges like the one uncovered in the Illumina iSeq 100 will be essential for safeguarding patient safety and data privacy. Collaborative efforts between cybersecurity experts, medical device manufacturers, and regulatory bodies will be crucial in mitigating the risks posed by firmware vulnerabilities and ensuring the security of medical devices in the future.
