In the first nine months of 2025, 293 ransomware attacks were recorded on hospitals, clinics, and other direct care providers, with an additional 130 attacks targeting healthcare businesses, including pharmaceutical manufacturers and medical billing providers. Attacks on healthcare businesses rose by 30% in 2025, while attacks on healthcare providers decreased by 8% compared to the same period in 2024.
2024 was the worst-ever year for breaches of healthcare records, with ransomware attacks rising to 67% of organizations. According to the AHA (American Hospital Association), a total of 444 reported incidents impacted healthcare in 2024, comprised of 238 ransomware threats and 206 data breach incidents.
These attacks lock down data, cancel surgeries, and reroute ambulances. Ransomware attacks in healthcare are more than just a data security problem; they are a direct threat to patient safety. Unsurprisingly, a recent survey found that nearly 70% of healthcare organizations report that cyberattacks disrupt patient care.
This guide provides statistics, proven prevention strategies, and a step-by-step emergency response plan for healthcare IT professionals and administrators.
Why does healthcare face more ransomware attacks than any other industry
For the 14th consecutive year, according to an IBM report, healthcare experiences the highest data breach costs of any sector, with breaches averaging $7.42 million and taking 279 days to detect and contain. In 2024, the average healthcare data breach cost $9.8 million, excluding ransom payments.
Healthcare organizations become prime targets due to three critical factors:
- Life-or-death urgency: Hospitals cannot afford downtime, making them more likely to pay ransoms
- Valuable patient data: Medical records sell for 10-50 times more than credit card numbers on dark web markets
- Legacy systems and medical devices: Unlike standard office computers, critical medical assets like MRI machines, ventilators, and infusion pumps often run on End-of-Life (EOL) operating systems (such as Windows 7 or XP). These devices cannot be easily patched due to strict manufacturer restrictions or FDA compliance hurdles, leaving them permanently exposed to exploits that modern security tools might miss.
The primary goal of healthcare ransomware attacks is financial extortion through double extortion tactics. In addition, ransomware attacks create immediate, life-threatening disruptions to healthcare delivery:
Patient Care Impacts:
- Emergency departments must divert ambulances to other facilities.
- Surgeries and procedures get canceled or postponed.
- Doctors lose access to patients' medical histories and medication records.
- Medical imaging equipment becomes inoperable.
- Laboratory results cannot be processed or accessed.
Operational Consequences:
- Staff resort to paper records and manual processes.
- Appointment scheduling systems go offline.
- Prescription systems become unavailable.
- Billing and insurance claims halt completely.
Healthcare ransomware statistics
- According to a 2024 report from cybersecurity firm Sophos, 67% of healthcare organizations were targeted by ransomware, a significant increase from 60% the previous year (Source: Sophos).
- U.S. breach costs rose to $10.22 million, despite the global average breach cost decreasing to $4.44 million. (Source: IBM).
- In 2024, 276.7 million healthcare records were breached, a massive increase driven by large-scale attacks on major health tech companies (Source: The HIPAA Journal).
- 56% of affected hospitals experienced delays in medical procedures, and tragically, 28% reported an increase in patient mortality(Source: IS Partners, LLC).

How to prevent ransomware attacks in healthcare
You can protect your healthcare organization and prevent cyberattacks by adopting a proactive, multi-layered security strategy that effectively shields your organization.
The top two entry points for ransomware are exploited vulnerabilities and compromised credentials, so your defenses must focus there. Exploited vulnerabilities emerged as the most common technical root cause of attacks for the first time in three years, used in 33% of incidents. Meanwhile, studies indicate that the most common organizational factor contributing to attacks was a lack of people/capacity, such as insufficient cybersecurity experts to monitor systems, cited by 42% of victims.
1. Build a human firewall through training
Your employees are your first and most important line of defense against attacks that use stolen credentials.
- Ongoing Education: Conduct regular, mandatory cybersecurity training for all staff, from clinicians to administrators. Use real-world examples of phishing emails and suspicious links.
- Simulate Attacks: Run regular phishing simulations to test employee awareness. These controlled tests can show you who needs extra training without any real risk.
- Explain the "Why": Teach staff why they are a target. Explain how a tactic like a man-in-the-middle attack can intercept communications, making it crucial not to trust unsolicited requests for information.
2. Implement robust technical safeguards
Technology is a critical layer of your defense, essential for stopping attacks that exploit software vulnerabilities.
- Patch Management: Apply security patches for all software, operating systems, and medical devices as soon as they are available. Attackers actively search for and exploit these known, unpatched weaknesses.
- Network Segmentation: Divide your network into smaller, isolated zones. This way, if one area is compromised (like guest Wi-Fi), the infection cannot easily spread to critical areas, like your Electronic Health Record (EHR) system.
- Advanced Email Filtering: Use an advanced email security gateway to scan for malicious links and attachments before they reach an inbox.
3. Enforce strong access and password policies
Cybercriminals often gain entry using stolen credentials. Limiting access and ensuring strong passwords can shut this door.
- Multi-Factor Authentication (MFA): Require MFA for all accounts, especially for remote access and access to critical systems. This means a password alone is not enough to get in.
- Principle of Least Privilege: Employees should only have access to the data and systems they absolutely need to do their jobs.
- Password Hygiene: Educate users on creating strong, unique passwords. With billions of credentials exposed in breaches, as detailed in the 16 Billion Passwords Leaked list, using a common or reused password is an open invitation for a breach.
What to do in case of a ransomware attack
Even with the best defenses, an attack can still happen. How you respond in the first few hours is critical.
Step 1: Isolate and disconnect
The moment you detect ransomware, your first action is to contain it. Disconnect the infected devices from the network immediately. Isolate affected network segments to prevent the ransomware from spreading.
Step 2: Activate your response team
Activate your pre-defined incident response plan. This team should include IT security, executive leadership, legal counsel, and communications.
Step 3: Contact law enforcement and recovery experts
Immediately contact your local FBI field office and CISA (Cybersecurity and Infrastructure Security Agency). You should also engage a professional data recovery service to safely assess the damage and determine if data can be restored from backups.
Step 4: Do NOT pay the ransom
The official guidance from the FBI and cybersecurity experts is clear: do not pay the ransom. Paying encourages future attacks, and there is no guarantee you will get your data back. Instead, focus on recovery by following a clear plan for what a company should do after a data breach, which includes forensic analysis and system restoration from clean backups.
Healthcare ransomware FAQ
What is the main objective of a ransomware attack in the healthcare industry?
The primary goal is financial extortion. Cybercriminals use malicious software to encrypt essential files (from patient records to scheduling systems), then demand ransom payment to unlock them. Healthcare organizations face added pressure because operational downtime directly impacts patient care and safety.
How does ransomware affect healthcare differently from other industries?
Healthcare ransomware attacks create life-threatening situations that don't exist in other sectors. When hospitals lose system access, they must divert emergency patients, cancel surgeries, and operate without access to critical patient histories.
How common are cyber attacks in healthcare?
Extremely common. Nearly 277 million healthcare records were breached in 2024, affecting patients across the United States.
