Cyber Vulnerabilities in Anesthesia Systems
Devices in operating rooms are increasingly vulnerable to cybersecurity threats, raising serious concerns for patient safety. Federal advisories and research have pointed to exploitable weaknesses in anesthesia machines, monitors, and related medical devices. These vulnerabilities are not just technical issues - they directly impact clinical risk and the reliability of life-support systems. Here’s a closer look at some key examples of these risks.
Anesthesia Machines and Ventilators
In July 2019, the U.S. Department of Homeland Security's Industrial Control Systems Cyber Emergency Response Team (ICS-CERT) issued a warning about a vulnerability in GE Healthcare's Aestiva and Aespire anesthesia machines (models 7100 and 7900). This flaw allowed hackers with network access to remotely modify gas settings, time records, and alarm functions. Notably, attackers didn’t need to know the specific location of the devices to exploit this weakness. Cybersecurity firm CyberMDX assessed the vulnerability with a CVSS score of 5.3, categorizing it as moderate. However, when viewed in the broader context of operating room risks, it was considered far more dangerous. Jon Rabinowitz from CyberMDX noted:
If this vulnerability were to be scored on a more holistic scale for risk, it would be considered critical.
While GE Healthcare acknowledged the issue, their internal investigation concluded there was "no introduction of clinical hazard or direct patient risk." [2]
Infusion Pumps in the Operating Room
Infusion pumps, essential for delivering precise medication doses during surgeries, are another area of concern. These devices often connect to hospital networks for data sharing and monitoring. Although public advisories specific to infusion pump vulnerabilities in operating rooms are scarce, the broader trend of network-connected devices highlights the potential risks. Any device integrated into a network can become an entry point for attackers.
Physiological Monitoring and Alarm Systems
The vulnerability in GE anesthesia machines also revealed how attackers could manipulate monitoring and alarm functions, leading to serious documentation and safety concerns. Elad Luz, Head of Research at CyberMDX, elaborated:
The potential for manipulating alarms and gas compositions is troubling. More subtle but just as problematic is the ability to alter timestamps that reflect and document what happened in surgery... Once the integrity of time and date settings has been compromised, you no longer have reliable audit trails. That's a very serious problem for any medical center. [3]
Nadir Izrael, CTO and Co-founder of Armis, underscored the broader implications:
The real concern when hacking medical devices [is] it only takes one hacked device to hurt or, forbid, kill a patient... They are about data and device manipulation; whether that is delivering too much anesthesia or stopping a respiratory device. [2]
These examples highlight the urgent need to address cybersecurity vulnerabilities in medical devices to ensure patient safety and maintain trust in critical healthcare systems.
How Cyber Vulnerabilities Affect Patient Safety
Cybersecurity gaps in anesthesia systems pose serious risks to patient safety, going far beyond just data breaches. When attackers exploit these systems, they can disrupt critical clinical workflows and tamper with medical data, putting patients' lives at risk during care.
Clinical Risks from Cyber Incidents
These vulnerabilities have the potential to cause immediate harm to patients. Hackers can remotely alter device settings, disable alarms, or manipulate medication delivery rates without the medical team's awareness. As Anthony James Cartwright from Cleveland Clinic Abu Dhabi highlighted:
It has already been proven that anaesthesia machines and infusion pumps can be hacked and their settings changes without the knowledge of the physician.[5]
A real-world example involves the Alaris Gateway Workstation, a system used to control multiple medication delivery devices. Researchers uncovered a security flaw that allowed malicious firmware to be installed. This vulnerability enabled attackers to change infusion rates for critical drugs, potentially leading to fatal outcomes.[5]
Even though some manufacturers downplay the risks - GE Healthcare, for instance, claimed there is "no direct patient risk" for its Aestiva and Aespire machines because anesthesiologists are present - the reality is more complex. Masked vital signs or silenced alarms could delay the detection of life-threatening complications during surgery.[5][6]
These clinical risks not only jeopardize individual patients but also disrupt the overall workflow in surgical settings, creating a ripple effect throughout the healthcare system.
Operating Room Disruptions
The impact of cyberattacks extends beyond individual patient care, often paralyzing entire surgical departments. Take the WannaCry ransomware attack in May 2017, for instance. This attack affected 600 organizations within the British National Health Service (NHS), forcing ambulances to reroute and surgeries to be canceled across 150 countries. The NHS alone faced an estimated loss of nearly $7.8 million.[7][4]
Another example occurred on October 28, 2020, when the University of Vermont Health Network suffered a cyberattack that shut down its electronic medical record system across six hospitals. This disruption left cancer patients without timely access to chemotherapy because providers couldn’t retrieve essential treatment protocols. It took almost a month to restore the system.[4]
Such attacks force healthcare teams to rely on manual processes, increasing the likelihood of errors. Without electronic medical records, coordinating services like blood banks, labs, and pharmacies becomes far more difficult - especially for patients in urgent need of surgical care. These disruptions not only compromise patient safety but also strain healthcare resources to their breaking point.
Vendor Risk and Regulatory Requirements
Vendor-related risks add another layer of complexity to the already significant challenges of patient safety in the face of cyber vulnerabilities. These risks often stem from technical weak points that can serve as gateways for cyberattacks. Issues like outdated operating systems and inconsistent patch management not only heighten security risks but also make it harder to comply with regulations aimed at safeguarding patient safety.
Common Vendor Risk Factors
A significant number of anesthesia devices still operate on outdated systems that no longer receive security updates. This leaves them exposed to emerging vulnerabilities, creating an open door for cyberattacks. Beyond security concerns, these legacy systems can also lead to clinical errors, especially when patches are delayed or fail to resolve issues effectively. Replacing these systems is often avoided due to the high costs involved, leaving healthcare facilities reliant on technology that may not meet modern security standards.
Patch management is another critical challenge. While some vendors respond quickly to address vulnerabilities, others are slower to act. Even when patches are available, applying them can be tricky, as healthcare providers must carefully balance the need for updates with the risk of disrupting clinical operations. Regulatory guidelines for patch management and device updates play a significant role in shaping how healthcare organizations handle these risks. Striking the right balance between maintaining compliance and ensuring patient safety remains a constant challenge.
The following section will delve into strategies for assessing and mitigating these risks to better protect patient care.
