WHEN MEDICAL SCANS END UP ONLINE: THE QUIET RISK HOSPITALS CAN FIX FAST

Attributed by Osama Alzoubi, Middle East and Africa VP at Phosphorus Cybersecurity

As Saudi Arabia races ahead in digital healthcare transformation, a quieter vulnerability lingers in the background: medical imaging systems that can be found – and sometimes accessed – directly from the public internet. Imaging infrastructure, diagnostic platforms, and hospital information systems are being modernized at speed improving outcomes, accelerating workflows, and bringing advanced clinical capabilities to more communities. But beneath this progress lies a quieter risk that rarely makes headlines: medical imaging systems being exposed on the public internet due to simple configuration errors.

Not a dramatic cyberattack. Not a threat actor breaching a firewall. Just avoidable misconfigurations that leave sensitive patient data reachable by anyone who knows where to look.

Medical imaging systems in Saudi Arabia face a persistent security challenge that differs from dramatic cyberattacks. Patient data exposure often occurs through configuration errors that leave systems accessible on the public internet. These technical oversights represent a significant vulnerability in healthcare’s digital infrastructure.

The Kingdom’s Personal Data Protection Law (PDPL) establishes strict requirements for handling health data. This legislation, modeled after international standards, mandates enhanced protection for medical information and imposes penalties for unauthorized disclosure. Hospitals must implement organizational and technical measures to prevent data exposure.

Radiology departments increasingly use digital platforms for case discussions and second opinions. Without proper configuration, these systems might allow unintended access to patient records. Teleradiology services, which expanded significantly during the pandemic, require secure transmission protocols to protect data during remote consultations.

When we hear about data breaches, we often imagine skilled hackers penetrating security systems. The reality is often simpler and more preventable. “Exposed” typically means a system is reachable from the public internet due to setup choices, not a sophisticated intrusion.

This happens in real-world healthcare settings for straightforward reasons: rushed deployments to meet clinical deadlines, vendor-supplied default configurations that were never changed, remote support access left open for convenience, and legacy systems that were connected to modern networks without proper security reviews.

The scale is significant. Research has identified over 1.2 million reachable devices and systems globally, including MRI scanners, X-ray systems, and related medical infrastructure. These are not theoretical vulnerabilities. They represent actual systems that can be found and accessed from anywhere with an Internet connection.

What gets exposed is more than images

Medical imaging files are not simply pictures. They carry identifiers and metadata that can connect scans directly to real people. Patient names, dates of birth, identification numbers, and clinical details often travel alongside the diagnostic images themselves.

This matters for several reasons. Beyond the obvious privacy violation, exposed patient imaging data creates risks of identity fraud, potential coercion or blackmail, serious reputational damage to healthcare institutions, and erosion of the trust patients place in their medical providers.

Security monitoring platforms have documented cases where exposed systems allowed direct access to both images and patient data—offering a level of detail that should never be open to anyone outside the clinical team.

Why this keeps repeating worldwide

Hospitals everywhere use similar device types and manage comparable data flows. The result is that the same setup mistakes appear repeatedly across different countries and healthcare systems. What starts as one hospital’s misconfiguration becomes everyone’s common failure mode.

The medical devices themselves often come with similar default settings. Imaging servers, picture archiving systems, and diagnostic viewers are deployed in comparable ways. When basic security steps are skipped during installation, the exposure follows a predictable pattern.

Health sector cybersecurity guidance from international authorities emphasizes the need for repeatable baseline controls precisely because these patterns recur. Reducing exposure requires not innovation, but consistent application of known protective measures.

Healthcare organizations face a common vulnerability pattern. A major healthcare provider addressed similar challenges across hundreds of hospitals, discovering that default passwords, vulnerable firmware, and device misconfigurations created entry points that threatened patient care and hospital operations across more than 500,000 connected medical and operational devices.

The Saudi-specific layer: connectivity at cluster scale

Saudi Arabia’s healthcare transformation includes the expansion of health clusters that connect multiple facilities into integrated networks. This approach improves care coordination and resource sharing, but it also means that one weak link can affect multiple sites.

National interoperability initiatives support the sharing of imaging and diagnostic reports across the healthcare system. The Saudi health ministry has established specifications for imaging data exchange through the national health information exchange platform, enabling providers to access patient scans regardless of where they were originally performed.

This connectivity is essential for modern healthcare delivery. It allows specialists to review scans remotely, supports second opinions, and ensures continuity of care when patients move between facilities. However, it also increases the need for consistent configuration rules and security standards across all connected sites.

When imaging systems within a cluster are not uniformly secured, the exposure risk multiplies. A misconfigured system in one facility can potentially provide access to data from across the entire cluster network.

A practical checklist hospitals can act on

Healthcare institutions can take concrete steps to reduce exposure risk. These are not theoretical recommendations but proven measures that address the most common vulnerabilities.

First, create a complete inventory. Every hospital should maintain a current list of what is connected to its network, including imaging devices, storage servers, viewing stations, web portals, and remote access tools. You cannot protect what you do not know exists.

Second, check external exposure. Verify that nothing sensitive is reachable from the public internet. This requires technical scanning from outside the hospital network to identify systems that respond to external queries. Many organizations discover exposures they did not realize existed.

Third, restrict remote access properly. Remote connections for maintenance and support should be tightly controlled, require strong authentication methods, and be removed entirely when no longer needed. Convenience should never override security when patient data is involved.

Fourth, implement safe setup procedures. Develop standard build guides for imaging systems, change all default passwords and settings, clearly document who owns each system, and establish responsibility for applying security patches and updates. Industry experience shows that default credentials remain one of the lowest barriers for attackers seeking entry into healthcare networks.

Fifth, conduct continuous checks. Exposure scanning should happen after any network changes, not just once annually. Healthcare networks evolve constantly, and new vulnerabilities can appear whenever systems are added or reconfigured.

These steps align with guidance from international cybersecurity authorities and health sector regulators, which emphasize reducing exposed services and strengthening baseline controls as priority actions for healthcare organizations.

The governance fix: make secure setup part of how clusters run

Individual hospital efforts are necessary but not sufficient. At the cluster level, governance structures must embed security into standard operations.

This begins with cluster-wide minimum standards for imaging systems and remote access. Every facility within a cluster should follow the same baseline security requirements, ensuring consistent protection regardless of which site a patient visits.

Clear ownership must be established for every system. Someone specific should be responsible for applying patches, approving access requests, and regularly checking for exposure. When accountability is diffuse, critical tasks get overlooked.

Procurement processes offer another leverage point. Purchase agreements should require vendors to provide secure default configurations, enable comprehensive logging capabilities, and commit to supported update cycles for the life of the equipment. Security should be a selection criterion, not an afterthought.

These governance approaches reflect sector framework guidance that encourages structured programs and repeatable controls rather than ad hoc responses to individual incidents.

Saudi Arabia has invested heavily in national cybersecurity frameworks and regulatory oversight across critical sectors, including healthcare. The foundation exists. The next step is ensuring those protections extend fully to the expanding ecosystem of IoT and IoMT devices — where simple configuration gaps can undermine otherwise sophisticated digital progress.

Prevent avoidable incidents

The goal is not perfection. Healthcare systems are complex, and some level of risk will always exist. The goal is removing the easiest path for data exposure: systems sitting openly on the public internet waiting to be found.

In connected healthcare, the quickest wins come from two simple principles: visibility and access control. Know what you have connected, and shut the doors that do not need to be open.

For Saudi Arabia’s health clusters, this represents an achievable objective. The infrastructure investments being made across the Kingdom’s healthcare sector create an opportunity to build security into expansion rather than retrofitting it later.

Medical imaging systems serve an essential clinical purpose. They should not also serve as unintended windows into patient data. With practical steps and consistent governance, hospitals can fix this quiet risk before it becomes a public incident.

In digital healthcare, exposure is rarely a mystery. It is usually a configuration. The question is not whether hospitals can fix it, but whether they will do so before patients pay the price.
