Amid the rise in ransomware assaults, the consequences often extend beyond mere data loss and financial burden. Have we considered the toll on human lives? Nowhere is the peril of ransomware more eminent than in the healthcare domain, where patients’ lives hang in the balance.
From 2015 onward, there has been a notable surge in ransomware strikes on healthcare establishments. The repercussions are grave: Emergency services redirected, critical treatments postponed, and, tragically, lives lost. The assurance that some ransomware factions pledged during the pandemic to spare healthcare entities has now been forsaken. Clearly, hospitals are now viewed as legitimate targets.
Ransomware attacks on healthcare institutions bring tangible harm to patients, affecting survival rates and endangering vital services. Additionally, ransomware assaults on crucial infrastructures pose severe threats to public health and safety.
The Peril of Ransomware in Critical Situations
Hospitals heavily rely on digital platforms for patient care management. Once a ransomware strike occurs, these systems become inoperative, yielding tragic outcomes. Research underscores the hazards: A 300% surge in ransomware attacks on healthcare since 2015, leading to a spike in emergency incidents such as strokes and cardiac arrests in hospitals inundated by patients redirected from facilities hit by cyber intrusions.
Findings from a study conducted by the University of California San Diego reveal that ransomware attacks on hospitals trigger a ripple effect. This results in neighboring hospitals experiencing a surge in patients, causing an 81% increase in cardiac arrests. Moreover, the survival rates for these cardiac arrest cases declined.
An illustrative case is the ransomware assault on Synnovis, a pathology services provider to the NHS in London. The attack disrupted blood tests and transfusions, leading to delays in critical cancer treatments and elective surgeries across multiple hospitals. This disruption epitomizes a recurring theme in ransomware incidents within healthcare: Delayed procedures and tests can escalate into life-threatening situations as time-critical treatments are deferred or overlooked completely.
Another study examining two urban emergency departments adjacent to an embattled healthcare entity revealed substantial increases in patient influxes, prolonged waiting durations, and elevated rates of patients “left unattended.” According to the research, these delays underscore the necessity for a disaster response strategy in such scenarios.
In some instances, the catastrophic aftermath of ransomware incidents in healthcare has been recorded in legal trials. In 2020, an individual sued an Alabama hospital, alleging that a ransomware attack was a contributing factor in her newborn daughter’s death. The hospital’s computer systems were offline during childbirth, impeding access to critical monitoring equipment and purportedly resulting in severe birth complications. While the lawsuit has been settled, it raises concerns about potentially similar occurrences that have gone unnoticed by the public.
Impacts of Ransomware Extend Beyond Healthcare
While the healthcare industry’s susceptibility to ransomware is particularly distressing, other critical infrastructure sectors are also confronting escalating risks. When Colonial Pipeline, a significant fuel distributor, fell victim to ransomware in 2021, it resulted in fuel scarcities throughout the Eastern U.S. Although direct fatalities were unreported, the ensuing panic potentially led to at least one fatal vehicle mishap as individuals hurried to stockpile fuel.
In critical infrastructure industries, the likelihood of loss of life or injury is substantial. Attacks on power grids, water supplies, and transportation networks could yield severe repercussions. Analysts caution that a ransomware assault on an energy grid, for instance, could disrupt power supply to hospitals, emergency services, and vulnerable communities, imperiling lives. If the healthcare sector serves as a paradigm, the aftermath of cyber intrusions on critical infrastructures transcends conjecture and looms as a plausible reality.

Unveiling Ransomware’s Lethal Implications
Though establishing a direct causal nexus between ransomware assaults and fatalities is intricate, recent data offers compelling insights. An analysis estimates that between 42 and 67 Medicare patients succumbed to ransomware assaults from 2016 to 2021. This estimate excludes data from private insurers. Furthermore, research accentuates the broader health ramifications, encompassing diminished care quality and postponed treatments. During cyber crises, hospitals often resort to manual processes devoid of the safety checks and efficiency of electronic health records, heightening the risk of errors and missed diagnoses.
The predicament isn’t confined to fatalities. Ransomware-induced delays can compound health issues, culminating in long-term complications and escalated healthcare expenses. A delayed diagnosis can portend the disparity between life and death for conditions like heart ailments, strokes, and sepsis. Consequently, ransomware assaults may result in surplus fatalities, even if the nexus is indirect.
Necessity for Resilience Against Ransomware Offensives
To mitigate the repercussions of ransomware on patient care, several hospitals have commenced implementing ransomware response techniques, such as Children’s National Hospital’s “Code Dark” protocols. These protocols are devised to ensure the continuity of care during system downtime, encompassing precise guidelines for manual record-keeping, communication strategies, and patient prioritization. Nevertheless, these measures have their limits. Genuine resilience demands preemptive measures like staff training, stratified security measures, and frequent system backups to curtail disruption.
As ransomware assaults grow more sophisticated, many in the cybersecurity domain advocate for policy revisions to confront the menace. A pivotal requirement is enhanced data exchange among healthcare entities, cybersecurity professionals, and governmental entities to monitor trends and respond promptly. Governments must elevate healthcare cybersecurity to the realm of national security, allocating resources and assistance to aid establishments in fortifying resilience against ransomware and other cyber hazards.
Combatting the Escalating Ransomware Menace
The vulnerabilities exposed in the healthcare sector serve as a stark reminder of the broader societal risks posed by ransomware. While healthcare providers are particularly prone, other critical infrastructure sectors face mounting jeopardy. As evidenced by the Colonial Pipeline episode, the reverberations of ransomware extend across entire regions, influencing fundamental services like fuel, water, and transport.
For cybersecurity experts, the upsurge in ransomware offensives against critical services necessitates a proactive defensive strategy. This encompasses advocating for stringent industry benchmarks, promoting the adoption of robust cybersecurity utilities, and fostering inter-sectoral collaboration to prepare for and counteract assaults. The objective is unequivocal: To attenuate the peril that ransomware poses to lives, whether directly or through impeded access to essential services.
