Protecting hospitals from IoT threats: How NVIS AI secures the future
The rise of the Internet of Medical Things (IoMT) has revolutionized healthcare, enabling real-time patient monitoring, remote consultations, and automated data collection. However, this rapid digital transformation has also exposed hospitals to unprecedented cybersecurity risks. One alarming example is the discovery of a backdoor vulnerability in Contec CMS8000 patient monitoring devices, which allows unauthorized access to patient data and remote execution of malicious files.
Hospitals are particularly vulnerable due to the interconnected nature of their systems. A single compromised IoMT device can serve as a gateway for attackers to infiltrate the entire network, manipulate patient data, or disrupt critical medical procedures. Given the growing threats to healthcare cybersecurity, hospitals must adopt robust security measures to protect patient data and ensure the integrity of medical devices.
This blog will explore the evolving cybersecurity threats in healthcare, analyze the risks associated with IoMT vulnerabilities, and explain how NVIS AI provides an advanced security solution to eliminate these threats.
Understanding IoT cybersecurity threats in healthcare
1. The Contec CMS8000 Backdoor: A wake-up call
Recently, the U.S. Cybersecurity and Infrastructure Security Agency (CISA) issued a warning about a critical security vulnerability in Contec CMS8000 patient monitoring devices. These devices, widely used in hospitals, contain a backdoor that:
Sends patient data to a remote IP address without authorization.
Allows attackers to download and execute malicious files on the device.
This type of vulnerability can have life-threatening consequences by leading to misdiagnosed conditions, delayed treatments, and manipulated patient records.
2. The expanding IoMT threat landscape
The 2025 check point state of cyber security report revealed that:
Healthcare is the second most targeted industry, with cyberattacks increasing by 47% year-over-year.
Ransomware attacks have evolved, with data exfiltration and extortion now more common than encryption-based attacks.
Supply chain attacks have surged, with 179% increase in hardware and semiconductor attacks—raising concerns about vulnerabilities embedded within medical devices.
With cybercriminals targeting healthcare institutions at an unprecedented scale, hospitals must adopt proactive security measures to prevent unauthorized access, data breaches, and system failures.
Common IoT Threats Facing Hospitals
1. Ransomware attacks
Ransomware has become one of the most devastating threats to healthcare. Attackers infiltrate hospital networks, encrypt critical patient data, and demand hefty ransoms for decryption. Given that hospitals rely on real-time access to patient records, the urgency to restore operations often forces them to pay the ransom—fueling the cycle of cyber extortion.
2. Data breaches and identity theft
Hospitals store vast amounts of sensitive patient data, including medical records, insurance details, and personally identifiable information (PII). If cybercriminals gain access to IoMT devices, they can steal and sell patient data on the dark web, leading to identity theft and financial fraud.
3. Supply chain vulnerabilities
Many hospitals rely on third-party medical device manufacturers for IoMT solutions. However, supply chain vulnerabilities can introduce hidden security risks—like pre-installed malware, unsecured firmware, or weak authentication protocols. If a single IoMT device is compromised, attackers can infiltrate the entire hospital network.
4. Distributed Denial-of-Service (DDoS) attacks
Cybercriminals often use DDoS attacks to overwhelm hospital servers, causing system crashes and operational delays. This can prevent doctors from accessing critical patient data, delaying emergency procedures and putting lives at risk.
5. Unauthorized access and insider threats
Weak authentication mechanisms allow attackers—or even malicious insiders—to gain unauthorized access to hospital networks. Once inside, they can manipulate patient data, disable medical devices, or install malware to further exploit the system.
How NVIS AI eliminates IoMT cyber threats
NVIS AI is redefining cybersecurity in healthcare by offering a Zero Trust security model, Layer 2 encryption, and blockchain-based data integrity to eliminate vulnerabilities in hospital networks.
1. Zero Trust Architecture: blocking unauthorized access
One of the key ways NVIS AI secures hospitals is by enforcing Zero Trust security policies.
Every access request is verified based on identity, device health, and contextual factors.
No user or device is automatically trusted, preventing attackers from exploiting weak authentication mechanisms.
Prevents lateral movement—even if a single device is compromised, attackers cannot move across the network undetected.
Unlike traditional security models that rely on perimeter defenses, NVIS AI assumes that every connection is potentially malicious—ensuring continuous verification for every access request.
2. Layer 2 Encryption: Protecting data in transit
Many cyberattacks exploit unencrypted network communications to intercept sensitive data. NVIS AI eliminates this risk by encrypting data at Layer 2, ensuring that:
Patient data remains encrypted while being transmitted between devices.
Attackers cannot intercept or manipulate medical records, even if they gain access to the network.
Medical device communications remain secure, preventing unauthorized remote execution of malicious commands.
By securing data at the data link layer, NVIS AI ensures that patient information remains protected even if attackers penetrate the hospital network.
3. Immutable blockchain-based audit trails
Cybercriminals often attempt to erase or alter logs to cover their tracks after breaching hospital networks. NVIS AI integrates Ethereum blockchain technology to:
Create immutable audit logs that cannot be tampered with.
Provide real-time monitoring of all network activities.
Flag suspicious activity immediately, enabling rapid threat response.
This blockchain-based approach ensures that every action within the network is permanently recorded, providing full visibility into security incidents.
4. Preventing supply chain attacks
NVIS AI helps hospitals validate their supply chain by implementing:
Real-time firmware analysis to detect hidden malware or vulnerabilities.
Endpoint security for IoMT devices, ensuring that only verified devices can connect to hospital networks.
Tamper-proof authentication protocols to prevent unauthorized firmware updates or device modifications.
By securing the entire lifecycle of IoMT devices—from manufacturing to deployment—NVIS AI eliminates the risk of supply chain vulnerabilities being exploited.
5. Real-time threat intelligence and virtual patching
Traditional security solutions struggle to keep up with evolving threats due to the complexity of updating IoMT firmware. NVIS AI offers real-time virtual patching, which:
Blocks new and zero-day attacks without requiring firmware updates.
Uses AI-powered threat intelligence to detect emerging attack patterns.
Prevents malware execution in real-time, reducing the risk of ransomware infections.
With NVIS AI, hospitals don’t have to wait for manufacturers to release security patches—they receive instant protection against new threats.
The takeaway?
As cybercriminals continue to evolve, so must our defense strategies. NVIS AI is leading the charge in securing hospitals and protecting patient data in an era where cybersecurity is no longer optional—but essential.
For healthcare institutions looking to fortify their security posture, NVIS AI is the ultimate shield against IoMT cyber threats.
