Cyber-Physical Threat Convergence: The Critical Security Risk from IoMT and
Additive Manufacturing
1.1 Expanded and Vulnerable Attack Surface from IoMT
Vast Number of Weak Endpoints: The proliferation of Internet of Medical Things
(IoMT) devices (e.g., connected monitors, infusion pumps) turns the hospital into a
massive network of easily compromised entry points.
Legacy and Unpatchable Devices: Many critical devices have long lifecycles and
operate on outdated firmware/OS with known vulnerabilities, making them
impossible to secure with standard patches.
Default Credentials and Poor Security Hygiene: Weak or hardcoded default passwords
and lack of robust authentication on IoMT devices allow attackers a simple initial
breach.
Lateral Movement: A compromised, non-critical IoT device (like a smart
thermometer) can be used as a pivot point to move laterally to high-value targets,
such as the Electronic Health Record (EHR) system.
1.2 Direct Threats to Patient Life and Data Integrity
Remote Life-Threatening Manipulation: Hackers can exploit vulnerabilities to
remotely hijack critical care devices (e.g., ventilators, pacemakers, infusion pumps),
altering drug dosages or shutting them down, leading to patient harm or death.
Ransomware Efficacy: The immediate dependence on connected systems makes
hospitals exceptionally vulnerable to ransomware attacks, forcing quick, high-value
payments to restore operations and resume care.
Diagnostic Corruption: Attacks can compromise diagnostic equipment or data in
transit, leading to erroneous medical readings that result in misdiagnosis or incorrect
treatment plans.
1.3 Introducing Cyber-Physical Risks via Additive Manufacturing (3D Printing)
Malicious Geometric/File Tampering: Custom medical prints rely on digital files
(CAD/STL). A cyberattack on the design or manufacturing network can subtly corrupt
the digital blueprint, introducing structural defects (e.g., micro-cracks) into a patientspecific implant or surgical guide, causing physical failure upon use.
Intellectual Property (IP) Theft: The digital design files for advanced 3D-printed
devices are valuable trade secrets. Theft of this IP allows for the unauthorized
counterfeiting of patient-specific medical devices.
Manufacturing Service Disruption: Attacks on the 3D printer controller or the supply
chain of print materials can halt the on-demand production of critical, personalized
medical tools, directly delaying time-sensitive surgical procedures.
