Here are the top 10 types of attacks targeting the Internet of Medical Things (IoMT) devices and systems, which pose significant risks to patient safety and healthcare operations:
The Internet of Medical Things (IoMT) refers to connected medical devices and systems that collect, process, and transmit health data via the internet. While IoMT offers significant benefits, such as improved patient care and streamlined healthcare operations, it also introduces vulnerabilities that attackers can exploit. Below are some key IoMT channel vulnerabilities:
Ransomware on IoMT Devices
Description: Attackers deploy ransomware to lock down IoMT devices or their connected systems.
Example: A ransomware attack on a hospital's IoMT ecosystem could disable critical devices like infusion pumps or ventilators.
Impact: Life-threatening delays in medical care, financial losses, and operational disruptions.
Man-in-the-Middle (MitM) Attacks
Description: Interception and alteration of communication between IoMT devices and central systems.
Example: Tampering with data transmission from a glucose monitor to a healthcare provider's system.
Impact: Delivery of inaccurate data, leading to incorrect diagnoses or treatments.
Device Hijacking
Description: Attackers gain unauthorized control of IoMT devices, allowing them to manipulate their functionality.
Example: Hackers controlling a pacemaker or insulin pump remotely to alter settings.
Impact: Direct risks to patient safety, including fatalities in extreme cases.
Distributed Denial-of-Service (DDoS) Attacks
Description: Attackers flood IoMT devices or connected systems with traffic, causing them to crash or become unresponsive.
Example: Overloading a hospital’s IoMT network, disabling patient monitoring systems.
Impact: Service interruptions, delayed patient care, and potential harm to patients.
Firmware Tampering
Description: Malicious actors exploit vulnerabilities in IoMT device firmware to install backdoors or malware.
Example: Exploiting an unpatched firmware vulnerability in medical imaging devices.
Impact: Persistent threats, data theft, or sabotage of device operations.
Signal Jamming
Description: Disruption of wireless communication between IoMT devices using radio frequency (RF) jamming.
Example: Preventing signals from a wearable cardiac monitor from reaching healthcare providers.
Impact: Loss of real-time monitoring and critical alerts.
Replay Attacks
Description: Attackers capture and resend legitimate signals or data packets to disrupt IoMT operations.
Example: Replaying authentication tokens to gain unauthorized access to an IoMT device.
Impact: Unauthorized access, manipulation of devices, or operational errors.
API Exploits
Description: Exploitation of insecure APIs used for communication between IoMT devices and healthcare systems.
Example: Gaining unauthorized access to a cloud-connected patient monitoring system.
Impact: Data leaks, compromised systems, and potential device manipulation.
Data Breaches via IoMT
Description: Exploiting IoMT devices as entry points to access sensitive patient data.
Example: Using a vulnerability in a connected infusion pump to infiltrate a hospital’s network.
Impact: Exposure of Protected Health Information (PHI) and compliance violations.
Physical Tampering
Description: Attackers gain physical access to IoMT devices to alter hardware or install malicious components.
Example: Tampering with a bedside monitor to compromise patient data or disrupt device functionality.
Impact: Direct compromise of patient safety and operational integrity.
