Critical Care at Risk: Combatting the Surge of Ransomware Attacks in Healthcare

ransomware attacks in healthcare

In 2023, the healthcare industry was ranked as the fourth most impacted by successful and publicly disclosed cyber-attacks[1], falling behind Manufacturing, Professional/Scientific/Technical, and ICT industries. Accounting for 9% of the total reported incidents, this statistic sheds light on the growing threat of cybercrime within healthcare.

Healthcare’s Battle Against Ransomware

Of particular concern within this sector is the rise of ransomware attacks, targeting healthcare organizations with alarming frequency. Cybercriminals execute sophisticated tactics to breach infrastructure, encrypt patient data or entire systems and hold them hostage. The reason? Financial gain, as these attackers demand significant ransoms in exchange for decrypting the captured data and restoring access to compromised systems.

Without delving too deeply into the past, the ransomware attack on medical firm Change Healthcare in late February has emerged as one of the most disruptive incidents in recent memory. Pharmacies across the US, including those within hospitals, experienced severe disruptions in the delivery of prescription drugs nationwide for over 10 days. Adding another layer of complexity to the situation, a dispute within the criminal underground has revealed a new development: one of the criminals’ partners behind the attack, known as AlphV or BlackCat , suggests that the hackers received a $22 million transaction resembling a significant ransom payment.

The ramifications of ransomware attacks in healthcare are profound and multifaceted. Beyond financial losses, these incidents disrupt essential healthcare services, jeopardizing patient safety and impeding critical medical procedures. The inability to access patient records and medical histories due to ransomware-induced data encryption can result in delayed treatments, misdiagnoses and compromised patient care.

Confirming the alarming trend of ransomware’s rise in healthcare is the dominance of malware as the preferred attack vector in 2023[2]. Malware, used in a remarkable 57% of cyber-attacks, has become synonymous with ransomware assaults. This represents a sharp escalation from previous years, with the employment of this attack method nearly doubling from 32% in 2022. The surge in malware-based attacks underscores the growing efficacy of malicious codes, particularly ransomware, in the arsenal of cybercriminals.

Insights into the Italian Scenario

In 2023, Italy witnessed a near doubling of successful and publicly disclosed cyber-attacks targeting its healthcare sector. These attacks underscored a concerning trend, with 93% of incidents inflicting severe or very severe impacts on the affected organizations[3].

Malware emerged as the predominant attack technique, constituting 73% of the year’s cyber-attacks, with ransomware being particularly prevalent. Indeed, such attacks have inflicted substantial damage, with more than 1.5 terabytes of health data equivalent to about 2 million files, exfiltrated and disseminated from Italian hospitals and healthcare companies in the final two months of 2023.

Identifying Risk Areas in Healthcare Organizations

Understanding the key risk areas within the healthcare industry is paramount for mitigating such risks and protecting patient privacy, safety, and organizational integrity. Here are a few examples of some critical aspects that need to be looked after:

Patient Records and Health Information. Patient records containing sensitive information such as medical history, diagnoses, treatments, and personal identifiers are prime targets for cybercriminals due to their value on the black market. Unauthorized access to this data can lead to identity theft, financial fraud, and compromise patient privacy.

Medical Devices and Equipment. The increasing connectivity of medical devices, such as infusion pumps, pacemakers, and imaging systems, introduces cybersecurity risks. Vulnerabilities in these devices could be exploited to disrupt patient care or manipulate medical treatment, if nobody properly configures and manages updates.

Supply Chain Partners. Healthcare organizations rely on various suppliers and vendors for medical equipment, pharmaceuticals, and other goods and services. However, these supply chain partners may introduce security vulnerabilities that could compromise patient data or disrupt operations without access, password management policies being established and followed.

Compliance. The healthcare sector is subject to numerous laws and regulations regarding data security, including GDPR and NIS2. Compliance with such regulations is crucial for safeguarding sensitive information and mitigating cybersecurity risks. Moreover, failure to adhere to these requirements can lead to penalties, fines, and reputational damage.

Human Factors. Employees, including healthcare professionals and administrative staff, can inadvertently introduce security vulnerabilities through actions such as falling victim to phishing scams, using weak passwords, or mishandling sensitive data.

In conclusion

As demonstrated by real-world incidents and statistics, the impact of ransomware attacks extends far beyond financial losses, disrupting critical healthcare services and compromising patient care. Therefore, it is imperative for healthcare organizations to prioritize cybersecurity measures, such as:

Regular Vulnerability Assessment and Penetration Testing to identify and remediate security weaknesses proactively;
Dedicated IoT security management solutions to secure connected medical devices and prevent them from becoming entry points for cyber attacks;
Security Operations Center and other managed security services for ongoing monitoring of network traffic, system logs, and security alerts to detect and respond to threats in real-time to protect patient data and services;
● Comprehensive training programs for employees at all levels to raise awareness of cybersecurity best practices, recognize phishing attempts, and understand their roles and responsibilities in maintaining a secure environment.

By embracing proactive security measures and fortifying their defences, healthcare organizations can effectively mitigate risks, protect patient data and services, and uphold the highest standards of patient well-being and care.
