Cybersecurity remains a paramount concern for healthcare organizations worldwide. Protecting sensitive health information from cybercriminals is not only vital for patient privacy but also essential for maintaining trust and operational integrity. Because protected health information (PHI) is significantly more valuable than other types of personal data, it has become a prime target for malicious actors. Healthcare records typically contain a broad array of personal details—such as names, social security numbers, financial data, and medical histories—making them highly attractive on the Dark Web, where health data can be worth up to 20 times more than financial information.

The costs associated with healthcare data breaches are substantial, often far exceeding those in other sectors. Remediation efforts involve expensive investigation and response processes, breach containment, and ongoing monitoring. For instance, the average cost to remediate a healthcare record breach is approximately $408 per record, compared to just $148 for non-health-related breaches. Despite these risks, many healthcare providers lag behind in implementing robust cybersecurity measures, leaving their systems vulnerable to attack.

Fortunately, a combination of advanced tools and best practices can help mitigate these threats. This article explores the current cybersecurity challenges faced by healthcare organizations and presents strategies to bolster data security.

Healthcare cybersecurity challenges

The landscape of healthcare cybersecurity has become increasingly complex, especially in recent years. The surge in data breaches and cyberattacks correlates strongly with the rapid adoption of remote work arrangements prompted by the pandemic. Healthcare organizations were forced to adapt quickly, often at the expense of comprehensive security protocols. The pandemic also led to an overload of patient care demands, which strained resources and diverted attention away from cybersecurity priorities.

Elective procedures, which typically account for around 60% of healthcare revenue, were canceled to curb virus spread. This resulted in a nationwide revenue loss estimated at approximately $22.3 billion. Financial constraints meant that many healthcare providers could not prioritize cybersecurity investments, leaving their systems exposed. As a consequence, cyberattacks increased sharply—more than one in three healthcare entities experienced ransomware incidents in 2020 alone.

Even as the pandemic subsides, cybersecurity threats persist and escalate. Data breaches in healthcare nearly doubled in the first five months of 2022 compared to the same period in 2021, highlighting the growing threat landscape. Key challenges include:

  • Mobile access: Many medical devices—such as insulin pumps, pacemakers, and wearable health trackers—rely on continuous internet connectivity. These devices often lack rigorous security measures, making them vulnerable to hacking. For example, over 61 million records linked to wearable devices like Fitbit were compromised in a 2021 breach, illustrating the risks of insecure connected devices. Protecting these devices requires robust network and file security protocols.
  • Legacy systems: A significant portion of healthcare hardware operates on outdated software that is no longer supported with security patches. Approximately 73% of healthcare providers still rely on legacy operating systems in their medical equipment. These outdated systems pose serious risks, as seen in the 2017 WannaCry ransomware attack, which exploited vulnerabilities in unpatched medical devices. Transitioning to modern, secure systems is essential but challenging due to costs and operational disruptions.
  • Staff shortages: Healthcare cybersecurity teams are often overstretched, undertrained, and understaffed. Around 33% of health IT teams lack sufficient staffing, and skills gaps are common—roughly 40% of IT staff lack cybersecurity expertise, with an additional 39% having limited data protection skills. This leaves organizations vulnerable to human error and delayed threat detection.
  • Broad attack surface: The extensive network of connected devices within hospitals—averaging 10 to 15 per bed—creates numerous entry points for cybercriminals. Many of these devices run on outdated software, increasing their susceptibility to exploitation. Securing such a vast and diverse array of hardware requires comprehensive, layered security strategies.

Common healthcare data threats

Cyber threats are pervasive across all facets of healthcare, from hospitals and clinics to pharmaceutical companies and research institutions. These entities handle vast quantities of sensitive data, making them prime targets. Teaching hospitals and research centers are especially vulnerable due to their large data repositories and ongoing data transfers.

Between 2018 and 2021, healthcare data breaches surged by 84%, impacting millions of individuals. In 2021 alone, over 44.9 million records were compromised, with more than 22 million breached in the US by mid-2022—a 4.6% increase from the previous year. The most prevalent threats include:

Phishing attacks: Cybercriminals use deceptive emails, fake websites, social media scams, and text messages to trick healthcare staff into revealing system access credentials. An illustrative case involved hackers infiltrating a Colorado-based eye care practice via an employee’s email, which resulted in the theft of over 26,000 patient records. Such attacks often lead to further breaches, ransomware infections, or data exfiltration. Healthcare organizations are particularly vulnerable, accounting for about half of all phishing victims. The financial toll of recovering from such incidents has risen to an average of $14.8 million, nearly triple the costs in 2015.

Third-party vulnerabilities: Many breaches originate through third-party vendors, suppliers, or business partners. In 2020, vulnerabilities in Accellion’s file transfer platform exposed millions of individuals’ health data. These incidents underscore the risks posed by third-party software and service providers that may lack adequate security measures. As noted in ranking the nations with the world’s best healthcare systems, robust third-party risk management is vital for safeguarding health data.

Ransomware attacks: Ransomware remains the most significant threat to healthcare data security. In 2021, approximately 66% of healthcare organizations experienced ransomware incidents—nearly double the rate from the previous year. Due to the critical nature of healthcare data and systems, organizations often feel compelled to pay ransoms—61% of the time—to restore access. This trend is dangerous; successful ransomware attacks encrypt sensitive health information in about 65% of cases, often leading to severe operational disruptions and even patient harm, such as compromised life-saving equipment.

The role of file security in preventing cyberattacks

Given the alarming rise of cyber threats, securing sensitive health data must be a top priority. One effective method is file encryption, which renders data unreadable without the proper decryption key. Encrypting data at the file level adds a vital layer of protection as information moves across devices, networks, and storage systems.

Advanced tools like WinZip® Enterprise facilitate secure file sharing, compression, and encryption, enabling healthcare organizations to centrally manage data security policies. Proper encryption not only prevents unauthorized access but also helps ensure compliance with regulations such as the Health Insurance Portability and Accountability Act (HIPAA). To stay ahead of increasingly sophisticated cyberattacks and learn more about implementing security solutions, organizations should explore practical ways AI can be implemented in healthcare settings.

In conclusion, safeguarding healthcare data against evolving cyber threats requires a comprehensive approach that includes technological defenses, staff training, and strategic risk management. By understanding the key vulnerabilities and deploying effective security measures, healthcare providers can protect their critical information assets and ensure continued trust and safety for patients.
