The connectivity that enhances healthcare also introduces risks, as more medical devices use software and connect to the Internet, hospital networks, and other medical devices. The proliferation of mobile devices and applications further complicates cybersecurity, adding numerous vulnerabilities.
The Escalating Frequency of Cyber Attacks
Advancements in technology have allowed healthcare organizations to operate more efficiently and save lives, but they have also opened the door to various cyber threats. Cybercriminals exploit these opportunities to infiltrate, steal, or hijack networks containing confidential data. Nation-states use software espionage tools and customized malware in social engineering attacks to steal intellectual property or gain competitive advantages. Cyberterrorists launch attacks to cause physical destruction, loss of life, and spread terror, while hacktivists target high-profile cyber assets to draw attention to their political causes. For instance, the second-largest healthcare insurance provider in the U.S. was targeted by a foreign government in 2014, highlighting the severity of these threats.
Healthcare organizations have increasingly become prime targets for cybercriminals. The reasons are manifold: sensitive patient data is incredibly valuable on the black market, and the critical nature of healthcare operations makes them lucrative targets for ransomware attacks. Over the past few years, incidents have surged, with hospitals, clinics, and even entire healthcare networks falling victim to sophisticated cyber intrusions.
Alarming Statistics and Recent Incidents
In 2021, over 40 million patient records were compromised in the USA due to major healthcare-related data breaches. This led to several warnings from the FBI about the risk of cybercrime in the healthcare sector. With the onset of the Russia-Ukraine conflict, the FBI has also warned about potential Russian hacks targeting US healthcare organizations. Data breaches affected over 22.6 million patients in 2021, with the largest single breach impacting more than 3 million individuals.
In Feb 2024, Change Healthcare, a unit of UnitedHealth Group’s Optum subsidiary, suffered a major ransomware attack by the cybercriminal group known as Blackcat (or AlphV). Reports indicate that the company paid $22 million in cryptocurrency to regain access to its systems. Security researchers and blockchain analysts confirmed a transaction of 350 bitcoins, approximately $22 million, linked to the ransomware group. The attack disrupted pharmacies and hospitals across the U.S., delaying prescription drug deliveries and healthcare services. Despite these disruptions, UnitedHealth stated that most U.S. pharmacies adapted to mitigate the impact, though they did not comment directly on the ransom payment.
In India, the healthcare sector faced over 1.9 million cyberattacks in 2022, as reported by the CyberPeace Foundation and Autobot Infosec Private Ltd. These attacks were traced back to IP addresses from Vietnam, Pakistan, and China. A significant incident involved a massive cyberattack on India’s top government-run hospital, AIIMS New Delhi, which forced it to shut down many of its servers and revert to manual operations.
A Paralyzing Ransomware Attack
The recent ransomware attack on Synnovis (June 2024) , a private firm providing blood test analysis for six NHS trusts in London, has once again highlighted the vulnerability of healthcare systems to cyber threats. The attack, attributed to the Russian Qilin criminal gang, has disrupted patient care for 2 million people, forcing hospitals and GP surgeries to scale back essential services, including cancer treatments, organ transplants, and maternity care. The incident, declared a “critical incident” by the NHS, underscores the growing sophistication of cybercriminals and the catastrophic impact such attacks can have on public health infrastructure.
The attack on Synnovis follows a well-established ransomware pattern: hackers infiltrate IT systems, encrypt critical data, and demand ransom payments in exchange for restoring access. This method effectively holds patient records and operational systems hostage, forcing hospitals to either pay the ransom or spend months rebuilding their IT infrastructure. The consequences have been severe, with major NHS trusts like Guy’s and St Thomas’ and King’s College Hospital canceling surgeries, postponing urgent procedures, and rationing the number of blood tests they can process.
Healthcare experts and cybersecurity analysts warn that the road to full recovery could take months, as IT teams work to assess the damage, secure systems, and restore operations without further compromise. Ciaran Martin, former head of the UK’s National Cyber Security Centre, compared the attack to “not just locking the NHS out of its own system, but kicking down the door and boarding it up again.” Even if the NHS regains access to its systems, the residual impact—corrupted data, compromised records, and disrupted workflows—could extend well beyond immediate recovery efforts.
Globally, healthcare has seen a surge in cyberattacks as more services move online. According to CheckPoint Research, the healthcare sector experienced the highest number of ransomware attacks globally during the third quarter of 2022. Ransomware attacks are particularly concerning as they leave hospitals and care facilities’ data vulnerable to hackers’ demands.
