The healthcare organizations are toiling hard to gain patient trust and seamlessly conduct their operations due to the frequent disruptions due to ransomware and other forms of threats. Ransomware-caused data breaches are the most common in the healthcare industry. The impact is worst on the healthcare finances. It has cost millions for US healthcare, impacting the overall health scenario as per the healthcare informatics cybersecurity news. 

Taking advantage of the interconnected healthcare technology, the cyberattackers try to get unauthorized access to numerous medical records at once, affecting the overall efficiency of healthcare systems. With proper healthcare cybersecurity solutions, it is possible to reverse the present scenario. Before finding out the most effective solutions, let’s learn more about some common cyber threats to health data. 

Common Cyber Threats to Healthcare Data

With the rising cyber attacks on the healthcare sector, different forms of the attacks are coming to light. Let’s find out about some common cyber attacks on patient health data. 

Ransomware

It is one of the most common types of malware that aims to block access to patient information through its encryption. The attacker then asks for a payment, i.e., ransom, to release the decryption key. If not paid, sensitive information can leak. Ransomware can paralyze the healthcare systems by spreading across the interconnected networks. This malware can affect healthcare operations, having a negative impact on health outcomes. It may also cause financial losses for healthcare organizations. 

Phishing

This is one of the major cyber-attacks in healthcare settings. In a phishing attack, the attacker sends fraudulent emails to trick healthcare officials into disclosing sensitive medical data. They trick the healthcare employees into downloading files containing malware, which then takes over the system. This is a dangerous cyber threat, especially spear phishing. Here, highly personalized emails are sent to specific healthcare officials. These emails seem trusted, and hence, the receivers are convinced to click on any link on the email, inviting the malware into the organization’s system. 

DDoS Attacks

Distributed Denial of Service or DDoS attacks aim to overwhelm the healthcare networks and disrupt emergency healthcare services. With electronic health records becoming inaccessible by DDoS attacks, it becomes difficult to access patient information, delaying necessary care. After DDoS attacks, it takes time, effort, and, most importantly, finances to restore back the system, increasing the financial burden for healthcare organizations. Reputational damage is another outcome as the stakeholders lose trust in the respective provider.

Insider Threats

This form of cyber threat is conducted by an insider of the organization, mainly one of the employees. In insider threat, a healthcare employee intentionally or unintentionally discloses sensitive patient information. Sometimes, healthcare employees do it intentionally to tarnish the reputation of the organization or just to fill their own pockets. Sometimes, the employees do it by mistake, primarily due to negligence. In both cases, the patient data is compromised and exploited. 

IoT Security Gaps

In this era of high connectivity among various medical devices, the occurrence of IoT-related breaches have become more common. IoT or Internet of Things focuses around interconnected devices that share information. For collaborative care, healthcare facilities often use such systems to ensure higher levels of patient outcomes. 

However, IoT security gaps such as outdated software, insecure communication, inadequate network segmentation, weak authentication, poor monitoring, and lack of IoT healthcare cyber security can result in unauthorized access, leading to operational disruptions. 

Social Engineering

This form of threat revolves around manipulation and impersonification. Here, the healthcare staff is approached by the attacker impersonating a healthcare employee or IT personnel, who then manipulates them to share sensitive information such as login credentials for healthcare systems. They can do a similar thing through phishing and pretexting as well. Voice-based attacks are also common, where they mimic the voice of a fellow colleague to extract medical information. 

Impact of Cyber Attacks On Patient Outcomes

The negative consequences of cyber-attacks are mostly associated with adverse patient outcomes. It is true that the restoration costs after an attack add up to the significant financial burden of the healthcare industry, but the patient satisfaction level is one of the key aspects to consider for several reasons. 

The cyber attacks on healthcare systems disrupt everyday healthcare operations, affecting numerous service users who access healthcare services through these platforms.
