Ransomware attacks have become an increasingly significant concern for the healthcare industry, with hospitals and medical organizations being targeted at an alarming rate. These attacks not only disrupt operations but also pose a serious threat to patient safety and well-being. Researchers have found that ransomware attacks on hospitals result in higher mortality rates, making it clear that the impact goes far beyond financial loss.
Hannah Neprash, an associate professor of health policy at the University of Minnesota, emphasizes the detrimental effects of ransomware attacks on patients. According to her research, patients admitted to hospitals during such attacks have a decreased likelihood of leaving the hospital successfully. The longer the disruption caused by the attack, the worse the health outcomes for patients. This highlights the urgent need for effective cybersecurity measures within the healthcare sector.
In the aftermath of a ransomware attack, it is common for external companies that have software connected to the targeted organization to suspend their services. This can range from disconnecting access to medical records to refusing to email victims of cyberattacks. To address this issue, assurance letters have emerged as a potential solution. These letters provide a guarantee that the necessary measures have been taken to safeguard against future attacks and that systems can be reconnected safely.
Assurance letters have gained popularity in recent years as breaches become more litigious, leading to legal disputes and lawsuits. Lawyers and security professionals have started requesting these letters, believing they are a legal requirement or a necessary precaution. However, there is no legal obligation to obtain an attestation before reconnecting systems. Chris Cwalina, the global head of cybersecurity and privacy at Norton Rose Fulbright, suggests that this practice may have originated from a misunderstanding of legal requirements or risk management.
In the preparation of assurance letters, cybersecurity companies specializing in incident response are often involved. These companies help assess the specific details of each attack and determine what can be reconnected and when. The decision-making process revolves around the perceived risk and the desire to ensure that systems are clean and free from attackers. Companies fear that cybercriminals may have gained unauthorized access and could potentially move laterally between the victims and their networks.
Charles Carmakal, the chief technology officer of Mandiant, a cybersecurity firm owned by Google, emphasizes the need to evaluate the actual risk associated with connectivity between parties. Rather than defaulting to the most restrictive path, organizations should carefully consider the likelihood of wormable ransomware spreading from one victim to another. While rare, it is essential to address concerns through a well-informed risk assessment rather than relying solely on restrictive measures.
Upon experiencing a ransomware attack, healthcare organizations have taken various steps to reassure their vendors and partners. Scripps Health’s Chief Information Officer, Thielman, mentions engaging independent cybersecurity experts and providing verification of malware containment and remediation efforts. Similarly, Ascension has communicated directly with vendors through one-on-one calls and webinars, sharing updates and indicators of compromise with health organizations and the US Cybersecurity and Infrastructure Security Agency (CISA).
The rise in cyberattacks against hospitals and medical organizations has raised concerns about the security of public infrastructure and services. While cybercriminals have claimed to avoid attacking hospitals, the reality is that these critical institutions are not exempt from targeted attacks. Such incidents prompt a fundamental question of whether governments should have the power to direct private firms on how to respond in these situations to mitigate the impact on public services and well-being.
Looking ahead, it is crucial for the healthcare industry and its stakeholders to prioritize cybersecurity and develop comprehensive strategies to prevent and respond to ransomware attacks effectively. This includes investing in robust security systems, enhancing workforce training on cybersecurity best practices, and fostering collaborations with cybersecurity experts. Additionally, regulatory frameworks and government support should be established to facilitate information sharing, incident response, and the prosecution of cybercriminals.
In conclusion, ransomware attacks pose a significant threat to patients, healthcare organizations, and public services. The detrimental effects on patient outcomes cannot be ignored, making it imperative for the healthcare industry to take proactive measures to protect against these attacks. Assurance letters, although not legally required, serve as a means to restore trust and reassure vendors. However, the decision to reconnect systems should be based on a well-informed evaluation of the actual risk rather than defaulting to the most restrictive path. Collaboration among healthcare organizations, cybersecurity experts, and governments is essential to effectively combat ransomware attacks and safeguard public infrastructure and services.
