Since the earliest days of cybercrime, healthcare data has been a prime target. Until recently, most cyberattacks on hospitals followed a familiar pattern: ransomware groups would encrypt patient records and demand payment. The motive was clear – and it was all about the money.
But cybersecurity experts are now warning of a shift. A growing number of attacks on health sector systems appear to be driven not by profit, but by politics. These incidents, often traced back to nation state-backed groups, aim to disrupt hospital operations, steal sensitive medical data, and undermine public trust. The United Nations has called cyberattacks on healthcare “a direct and systemic risk to global public health and security.”
This evolution comes at a vulnerable time, as trust in health institutions remains fragile. Cyberattacks deepen that mistrust, strain critical infrastructure, and blur the line between criminal enterprise and geopolitical strategy. As someone working at the intersection of healthcare security and intelligence sharing, I believe this is no longer just a criminal problem – it’s a threat to national security.
The challenge of attribution
As the motives behind cyberattacks on the health sector shift, so too does the complexity of understanding who is behind them – and why.
Unlike the straightforward financial motives of traditional ransomware groups, state-backed campaigns are often hidden behind layers of sophisticated proxies, hacktivist fronts, or loosely affiliated cybercriminals. What may initially appear to be a routine ransomware incident could, upon deeper investigation, reveal signs of a coordinated strategy: targeting critical healthcare infrastructure, maximizing operational disruption, and carefully avoiding attribution to any nation-state.
This pattern has already been seen in high-profile cases. During the COVID-19 pandemic, several European healthcare institutions suffered cyberattacks that officials later suspected were linked to foreign intelligence operations. Although the attacks initially resembled criminal ransomware campaigns, deeper analysis pointed to broader aims – such as stealing vaccine research, disrupting care during a public health emergency, or sowing mistrust in the healthcare system.
This deliberate ambiguity serves the attackers well. By masking strategic sabotage as criminal activity, they sidestep direct political consequences while still inflicting serious harm on institutions providing patient care. For defenders, this blurred line between crime and geopolitics complicates the response at every level: technical, operational, and diplomatic.
In the health sector, patient safety is at immediate risk during a cyber incident, and there is little time or capacity for in-depth forensic analysis. Without a clear understanding of the nature and purpose of an attack, hospitals and healthcare providers may misjudge the threat, miss broader patterns, and fail to coordinate an appropriate defensive strategy.
Importance of intelligence sharing
The key to building an effective defense is collective action, which depends on the free exchange of information. Critical infrastructure organizations are coming together to form Information Sharing and Analysis Centers, or ISACs. Health-ISAC brings together more than 14,000 people through anon-profit industry association designed to facilitate trusted exchanges of cybersecurity threat intelligence, enabling faster, more coordinated responses to emerging risks. Health-ISAC connects hospitals, pharmaceutical companies, insurers, and other stakeholders, creating an ecosystem where knowledge flows more freely and early warnings can be amplified across the global health community.
By sharing indicators of compromise, attack techniques, suspicious behaviors, and lessons learned, organizations can turn isolated observations into industry-wide intelligence. A malware signature spotted in a single hospital today could be the early warning that prevents a wave of attacks across the entire globe tomorrow. In this way, intelligence sharing transforms defense from a series of isolated struggles into a coordinated, proactive effort.
However, building and sustaining this kind of collaboration is not without its challenges. Effective sharing depends on trust: trust that sensitive information will be handled responsibly, and trust that participants are committed to mutual defense. Health sector organizations must be willing to report incidents transparently. Fostering this culture of openness remains one of the sector’s greatest challenges, but also one of its most powerful opportunities to strengthen the industry against increasingly sophisticated threats.
Building resilience
While robust cybersecurity controls remain essential, the reality is that preventing every attack is impossible. Therefore, health sector institutions must invest in resilience: the ability to maintain or quickly restore critical services under attack.
That starts with preparation. Organizations should develop and regularly rehearse detailed incident response plans tailored to their specific workflows, facilities, and patient care requirements. These exercises help staff know what to do when systems go down and ensure that decision-making isn’t delayed by confusion or uncertainty during a crisis.
Segmented network architectures are another critical defense. By isolating systems – such as separating medical devices from administrative tools or confining lab networks to their own segment – organizations can prevent malware from moving laterally and causing widespread disruption. This kind of compartmentalization limits damage and buys valuable time for response teams.
Equally important is the strength and accessibility of backup and recovery systems. Backups should be stored securely, tested regularly, and maintained in offline or immutable formats to prevent them from being manipulatedduring an attack. The faster an organization can restore patient records, scheduling tools, and communication systems, the sooner it can return to safe and effective care.
Final thoughts
Too often, cyberattacks reveal that resilience was treated as an afterthought. But in the health sector – in which lives are on the line – it must be a foundational priority. Planning, practice, and coordination are no longer optional. They are the frontline defenses in a cyberwar hospitals can no longer afford to ignore.
What’s needed now is a shift in mindset. Health sectorleaders must view cybersecurity not as an IT issue, but as a core part of patient safety and institutional trust. That means allocating resources, engaging staff at every level, and collaborating beyond organizational boundaries.
No single hospital can stand alone against the forces reshaping the threat landscape. But together – through shared intelligence, coordinated response, and a renewed focus on resilience – the health sector can push back against this rising tide and protect the critical systems millions rely on every day.
