Key Cybersecurity Threats Affecting the Healthcare Sector

Organisations are becoming increasingly susceptible to attacks – threatening day-to-day work and compromising confidential patient data and safety. Healthcare organisations are struggling to keep at pace with the rapid increase and sophistication of attacks on healthcare organisations. With attackers increasingly looking to profit from the disclosure of sensitive patient data, healthcare organisations should ensure strong technical security controls are in place to ensure the risk of data breaches is reduced.


66% of healthcare organisations say they experienced a ransomware attack in 2021, an increase from 34% in 2020.


74% of ransomware attacks were aimed at hospitals, and 26% at secondary institutions like dental services and nursing homes.

CYBER SECURITY CHallenges in THE Healthcare Industry

Data Breaches

The average cost of the healthcare data breach was $9.6 million in 2021. So, it’s clear that data breaches are one of the biggest challenges for the healthcare sector. The emphasis is on proper device management and monitoring and encryption of sensitive data related to patients and their medication. Data breaches exposed at least 42 million records between March 2021 and February 2022. 

Insecure Medical Devices and Equipment

Modern-day hospitals are one humongous basket of healthcare-related data. All healthcare professionals utilise connected medical devices to treat patients. With frequent use of such medical devices and equipment, having secure access to them is paramount. Unfortunately, most hospitals don’t give much importance to this aspect, which becomes a reason for a major cyberattack. Around five million unsecured medical devices were running through IoT and IoMT in 2020. It offers a chance for attackers to access insecure devices and take complete control.    

Ransomware Attacks

Ransomware is a subset of malware in which attackers take the data on a victim’s computer through encryption and demands payment for decryption and return of access. Of all the new age cyberattacks healthcare professionals face, Ransomware is the most dangerous. Globally, Ransomware accounted for 304.7 million attacks in the first half of 2021, an increase of 151% since 2020. Cybercriminals cause these attacks through trojan viruses affecting computers or phishing mail when the users click on a link to download a particular attachment.

Lack of Cyber Awareness

Medical professionals do not have the necessary expertise to recognise and mitigate cyber threats. Budget, resources, and time constraints mean it’s simply impossible for all healthcare staff to be fluent in cybersecurity best practices. A report analysed by Health IT revealed that nearly 24% of health employees in the U.S. hadn’t received any cybersecurity awareness training to help identify phishing scams.
