TL/DR –
Cybersecurity firm Modat has discovered over one million healthcare Internet of Things (IoT) devices and connected medical systems exposed online, potentially leaking sensitive patient data due to lax security practices. The problem has escalated, with over 1.2 million devices now at risk, potentially leading to life-threatening errors if hackers manipulated device settings. Despite a booming healthcare IoT security market, regulatory responses are lagging and the use of outdated protocols and legacy systems highlights the need for robust protocols and a security-first mindset in the healthcare sector.
Digital Health Infrastructure Vulnerability: Over 1 Million Healthcare IoT Devices Exposed
In a stark exposure of digital health infrastructure’s fragility, cybersecurity firm Modat discovered over one million healthcare IoT devices and connected systems leaking sensitive patient data online. Data such as detailed medical scans, personal records, and real-time monitoring information from devices like MRI machines and infusion pumps have been exposed due to lax security measures like unpatched software and default passwords.
The United States leads with over 500,000 exposed devices, followed by South Africa and Australia. Modat’s analysis revealed many systems operating outdated protocols like DICOM for medical imaging, which lack modern encryption. This lax security has led to breaches, including access to unencrypted X-ray images and patient histories, highlighting identity theft and medical fraud risks.
Global Healthcare Networks Vulnerability Scope
This exposure is part of an ongoing pattern of IoT insecurities in healthcare. A Healthcare IT News report last year outlined similar weaknesses. Modat’s latest data shows the problem has escalated, with over 1.2 million devices now at risk, as outlined on Cybersecurity News.
Hackers manipulating device settings could lead to life-threatening errors. An industry survey noted by IoT For All states that 75% of such devices have vulnerabilities, increasing risks in an era where healthcare doubles its data generation every two years.
Historical IoT Breaches and Emerging Patterns
Similar incidents have been reported, including a 2023 case where vulnerable IoT endpoints compromised millions of patient records. Regulatory responses have been slow. Despite the Editverse’s 2025 guidelines emphasizing security protocol compliance, enforcement remains inconsistent. GDPR fines have targeted similar breaches in Europe, but U.S. healthcare providers often prioritize connectivity over security.
Healthcare IoT Security Market Growth Amid Persistent Security Gaps
Despite these security gaps, the healthcare IoT security market is projected to reach $3.52 billion by 2034. However, widespread fixes haven’t been implemented. Censys experts recommend zero-trust architectures to mitigate risks in their blog on IoHT exposures.
Strategies for Future Safeguards and Mitigation
Healthcare leaders are urged to adopt multi-layered defenses, including AI-driven anomaly detection and regular penetration testing. Despite these strategies, many hospitals view IoT as efficiency tools rather than security liabilities. Reports predict stricter regulations by 2026, mandating IoT device certification, but until then, proactive measures like firmware updates are essential.
Implications for Patients and Providers
The risks extend beyond data theft to physical harm for patients. Providers also face legal repercussions from data breaches. A significant example is the Episource incident—stealing data from 5.4 million users, as reported by TechRadar. The industry must prioritize security to prevent further breaches.
