Guide
Ransomware has become one of the most pervasive cyber threats organizations face today. It’s a form of malware that locks or disables access to data until a ransom is paid, and it’s evolving in alarming ways.
With the rise of cloud infrastructure, bad actors are increasingly targeting these environments, making it essential for businesses to prioritize cloud security. Below, we’ll explore ransomware trends, spotlight the healthcare sector as a key target, examine root causes, and share actionable solutions to protect against attacks.
Ransomware Trends in Cloud Environments
Unfortunately, cybercriminals have expanded their focus to include cloud environments, such as Amazon S3 buckets and Azure Storage accounts. Recent reports highlight a 13% rise in ransomware attacks on cloud resources over the past five years, underscoring the need for robust cloud security solutions as businesses increasingly migrate to and operate in cloud-based systems.
Key Statistics on Ransomware Growth
Targeted Industries: Healthcare leads as the most targeted sector. Between August 2023 and July 2024, 21% of reported ransomware incidents hit healthcare organizations, up from 18% the year before.
Skyrocketing Costs: Across all industries, the average ransom payment in 2024 rose to $2.73 million, with healthcare reporting a median payment of $1.5 million.
Extended Recovery Times: Only 22% of businesses affected recovered in under a week, a stark decline from 47% the previous year.
These alarming numbers make it clear: strengthening defenses is no longer optional, especially for industries like healthcare that safeguard highly sensitive data. The stakes are simply too high to ignore.
The Healthcare Sector Under Siege
The healthcare industry is a prime target for ransomware in the cloud. Disruptions in electronic medical records (EMR) or critical IT systems can jeopardize patient care and result in fines for non-compliance. A few recent incidents highlight the alarming scope of the issue:
- Change Healthcare (February 2024): This attack on a UnitedHealth Group subsidiary halted medical claims processing and electronic payments, costing the company nearly $3 billion. Ransomware attacks on healthcare systems are more than just a tech issue—they’re a direct threat to patient safety. When patients can’t afford vital prescriptions due to system disruptions, the consequences can be life-threatening, highlighting the urgent need to prioritize cybersecurity in healthcare.
- Ascension Health (May 2024): Personal data for 5.6 million individuals was compromised during this attack, forcing hospitals to rely on pen and paper for weeks. Critical IT systems remained offline for six weeks, severely disrupting care across 136 U.S. hospitals.
- Synnovis in the UK (2024): A ransomware attack on this NHS laboratory services provider canceled thousands of medical procedures and revealed 400GB of sensitive patient data. The financial impact far exceeded prior profits for the organization.
Unfortunately, these are only a few instances of ransomware attacks on healthcare, and they highlight the life-threatening consequences ransomware can have when it infiltrates critical healthcare systems.
Root Causes of Ransomware in Cloud Systems
To tackle ransomware, it’s crucial to first understand its root causes. Most attacks exploit a mix of technical vulnerabilities, human errors, and systemic issues.
Common Weaknesses that Enable Ransomware
- Weak Cloud Security Practices: Poor password hygiene and lack of multi-factor authentication leave systems open to exploitation.
- Unpatched Vulnerabilities: Delayed updates in cloud applications and operating systems give hackers access to known security gaps.
- Misconfigured Systems: Incorrect setups of cloud services or databases often expose sensitive data unknowingly.
- Legacy Systems: Older infrastructure often lacks modern defenses, making it a soft target for cybercriminals.
- Unsegmented Networks: If critical data is not isolated, ransomware can easily spread across the system once it infiltrates.
- Absence of Backup Plans: Without secure and reliable backups, organizations face the agonizing choice of paying ransoms or losing vital data forever.
Addressing these root causes minimizes the chances of an attack and helps with recovery if one occurs.
How To Protect Against Ransomware in the Cloud
Defending against ransomware involves proactive planning as well as reactive measures. The NIST Incident Response Framework offers an effective roadmap for both preventing and responding to attacks. By addressing potential vulnerabilities, organizations can significantly reduce their risk:
Preparation
- Risk Assessment: Regular audits can uncover vulnerabilities and misconfigurations in cloud environments.
- Enhance Access Controls: Implement role-based access and multi-factor authentication to restrict unauthorized access.
- Timely Patching: Keep software and systems updated to eliminate exploitable weaknesses.
- Regular Backups: Store secure, offline backups to avoid paying ransoms in the event of an attack.
- Staff Training: Educate employees about phishing and ransomware tactics to reduce human error.
Detection and Analysis
Use advanced monitoring tools and anomaly detection systems to identify suspicious activity, such as mass file encryption or unauthorized data access. Machine learning models can also help spotlight unusual patterns in cloud usage.
Incident Response
When ransomware strikes, speed and precision matter. Focus on containment by isolating affected cloud environments to stop lateral movement, and follow predefined incident response playbooks to streamline recovery efforts.
Recovery
Recovery should include secure data restoration and validation to ensure no malware persists. Document every step of the process to improve future defenses and meet compliance reporting requirements.
By combining preparation, detection, swift incident response, and thorough recovery measures, organizations can minimize the impact of ransomware attacks and strengthen their overall cybersecurity posture.
The Bottom Line: Prioritizing Cloud Security in Healthcare
Healthcare organizations must proactively defend against ransomware to protect patient data, maintain trust, and ensure operational continuity. By strengthening cloud security practices, implementing real-time monitoring, and adopting a NIST-based incident response strategy, organizations can significantly reduce risk.

FAQ
What is ransomware in the cloud and how does it work?
High-quality data ensures that healthcare organizations can make accurate diagnoses, improve patient outcomes, comply with regulations, and streamline operations. Conversely, poor data quality can lead to errors, financial inefficiencies, and loss of patient trust.
How can healthcare organizations protect against ransomware attacks in the cloud?
Healthcare organizations can defend against cloud ransomware threats by implementing NIST-recommended cybersecurity best practices, including:
- Access Control – Enforce zero-trust policies, role-based access controls (RBAC), and MFA.
- Regular Patching & Updates – Address known vulnerabilities in cloud infrastructure.
- Data Encryption – Encrypt sensitive patient data stored in AWS, Azure, or GCP.
- Automated Threat Detection – Deploy AI-driven cybersecurity solutions to monitor and mitigate attacks.
- Backup & Recovery Plans – Use immutable backups to prevent data loss and reduce ransom risks.
What are the most common causes of ransomware attacks in cloud environments?
The most common causes of cloud ransomware attacks include:
- Weak security configurations – Unsecured cloud storage buckets, lack of MFA, and misconfigured firewalls.
- Phishing attacks – Cybercriminals trick employees into granting unauthorized access.
- Unpatched vulnerabilities – Delayed software updates expose systems to exploitable weaknesses.
- Compromised credentials – Stolen login credentials lead to unauthorized cloud access.
- Lack of segmentation – Poor network isolation allows ransomware to spread across cloud environments.
