Healthcare providers are facing a sharp rise in cybersecurity attacks, and as the number of those attacks increases, so does the number of patients affected. Recent data shows ransomware attacks surged by 36% in late 2025 compared with the previous year, with the healthcare sector accounting for more than one-third of all reported attacks. At the same time as these threats grow, the attack surface for healthcare organizations now extends well beyond the four walls of hospitals and clinics. Cloud adoption, remote access and AI-driven workflows have severely widened healthcare attack surfaces. This signals a turning point for providers, hospitals and health systems alike: security is no longer an IT concern, but rather it is necessary for patient safety and business continuity.

Healthcare IT models and systems were originally built for closed environments that were far less exposed by malicious actors. But today’s threat landscape means that these legacy systems need to be updated for cybercriminals capable of exploiting security vulnerabilities at scale and at an unprecedented speed. This shift also means that patients can be vulnerable no matter where they are, whether physically at an appointment or communicating virtually with a physician.

On top of operational and security implications, healthcare is also one of the most expensive industries when it comes to data breaches. In the United States, the average cost of a healthcare breach climbed to $10.22 million dollars per incident, up 9.2% year over year. The more expensive these breaches get the harder it becomes to recover patient data and ensure security does not impact treatment. The bottom line is that cybersecurity is now intertwined with patient care, meaning that preparedness, visibility and recovery are not optional, they're essential.

From EHR Breach to Recovery Readiness

The recent CareCloud incident underscores how a single compromised electronic health record (EHR) environment can expose sensitive patient data and disrupt critical operations. The cloud-based software provider’s network was temporarily disrupted, including functionality and data access to one of its six electronic health record environments for roughly eight hours.

CareCloud stores electronic health records storage, for more than 45,000 providers, including doctors and physicians at thousands of hospitals and medical practices, covering millions of patients. EHR providers are rich targets for financially motivated cybercriminals who can leverage the data to halt care and lead to widespread outages.

The threat was limited to its CareCloud’s Health environment and did not affect other platforms, divisions, systems, data or environments. However, given the sensitivity of the potentially compromised information, the possible consequences of these types of incidents include reputational damage, legal and regulatory requirements, and incident response costs. Ransomware in healthcare can also severely disrupt patient care by blocking access to electronic records, delaying treatments and forcing error-prone manual processes, ultimately compromising safety and efficiency. This can also erode patient trust and create emotional distress, making strong data protection, rapid recovery and transparent communication all the more essential.

The rise of similar attacks like these is ushering in a shift in healthcare security. Today, it is no longer enough to just prevent attacks; healthcare organizations must make sure they have a confident disaster and data recovery plan that will restore data quickly without relying on systems that may already be compromised. Disaster recovery allows organizations to restore operations after a paralyzing incident through the protocols, policies and technical safeguards that either prevent incidents from happening or accelerate the recovery process in the aftermath.

Disaster Recovery Requires More Than Backups

Effective disaster recovery requires a multi-layered approach that includes regularly patching software to address vulnerabilities, maintaining frequent immutable backups as a last line of defense and using software composition analysis to monitor open-source risks. Organizations must also conduct compliance audits to meet legal requirements and invest in employee education to reduce human error, which remains a major source of security incidents.

Building Resilient Healthcare Systems

On top of disaster recovery, modern healthcare enterprises need to adopt a Zero Trust mindset. Zero Trust is a security paradigm replacing the more traditional and increasingly ineffective perimeter-based security approaches of the past. Adopting a Zero Trust approach includes assuming breaches, enforcing strict identity-based access with least privilege, and maintaining continuous monitoring, automation and data governance to minimize risk.

Why Legacy Systems Increase Risk

While new software and hardware can be expensive, the cost of a large-scale data leak is even greater. Replacing legacy technology to prevent data leaks is essential to keeping healthcare organizations safe. Data backup is the process of using hardware and software to create secure, reliable copies of your organization’s data for safekeeping. It’s an indispensable practice, thanks to which your information is always protected and accessible when needed. Backups protect businesses from data loss caused by human error, hardware failure, cyberattacks, disasters and software corruption, while ensuring continuity and recovery. They also support regulatory compliance by safeguarding sensitive information and preventing costly penalties.

For example, a ransomware attack on a hospital could disrupt systems across multiple locations and also impact the backup environment itself. Even if the hospital is recovery-ready from the start, restoration will be delayed until new infrastructure is available, after which systems are rebuilt in a clean environment using backups. Ultimately, absolute immutable data backups are the only solutions that will ensure backups stay protected and enable fast, reliable recovery once operations resume.

The Role of Immutable Backups in Ransomware Recovery

Data backups can only be absolutely immutable if it allows Zero Access to perform destructive actions. Nobody, even the most privileged admin or attacker with access to backup storage, can modify or delete data. Absolute Immutability is achieved through standards-based S3 object storage with verifiable built-in protections, instant immutability at the moment data is written, and a dedicated storage appliance that isolates and secures backups while minimizing user risk and responsibility.

As cyber threats continue to escalate, healthcare organizations must recognize that security is inseparable from patient care and operational resilience. By prioritizing Zero Trust principles, modernizing legacy systems and investing in absolutely immutable backups and rapid recovery strategies, providers can better safeguard sensitive data, maintain continuity, and ensure patient trust in an increasingly high-risk digital environment.
