Ransomware Attack on Blood Supplier OneBlood Disrupts Healthcare System

A recent ransomware attack on OneBlood, a major blood supplier, has severely disrupted the blood supply chain in Florida, prompting urgent health warnings and a call for donations. This cyberattack underscores the critical vulnerability of healthcare infrastructures and the far-reaching implications of such breaches.


OneBlood is a leading blood supplier in the southeastern United States, responsible for providing vital blood products to hospitals and healthcare facilities across the region. The organization plays a crucial role in maintaining a steady supply of blood, essential for surgeries, trauma care, and various medical treatments. OneBlood supports over 250 hospitals, making its operations critical to the health and well-being of countless individuals.

In late July 2024, OneBlood became the target of a sophisticated ransomware attack that crippled its IT systems. The cyberattack resulted in significant operational disruptions, affecting the organization’s ability to collect, test, and distribute blood products. The attackers encrypted sensitive data and demanded a ransom to restore access.

Florida health officials, particularly in Orlando, quickly raised alarms about the potential public health crisis due to the disrupted blood supply. They urged residents to donate blood to mitigate the shortage exacerbated by the cyberattack.

The attack on OneBlood highlights the increasing frequency and severity of ransomware attacks targeting critical infrastructure. Such incidents not only compromise sensitive data but also have tangible, life-threatening consequences. In the case of OneBlood, the disruption has led to delays in medical procedures and heightened risks for patients in need of urgent blood transfusions.

Ransomware attacks on healthcare facilities can be particularly devastating due to the nature of the services they provide. Unlike other industries, healthcare cannot afford prolonged downtimes without risking lives. This vulnerability makes healthcare organizations prime targets for cybercriminals seeking high ransom payouts.

Moreover, the ripple effects of such an attack can extend beyond immediate health impacts. Hospitals and clinics relying on OneBlood for regular blood supplies are forced to delay elective surgeries and other non-urgent procedures to conserve their limited blood resources for emergency cases.

Since the attack, OneBlood has been working diligently to restore its systems and resume normal operations. According to recent reports, the organization’s IT infrastructure is gradually recovering, and blood collection activities are being reinstated. However, the process is ongoing, and the full extent of the recovery efforts is yet to be determined.

OneBlood has also been transparent about the steps it is taking to enhance its cybersecurity defenses. This includes working with cybersecurity experts to investigate the breach, strengthen its systems, and prevent future attacks. The organization has emphasized its commitment to safeguarding the health and safety of the communities it serves.

This is not the first time the healthcare sector has faced significant disruptions due to ransomware attacks. In 2021, Ireland’s Health Service Executive (HSE) experienced a major ransomware attack that paralyzed its IT systems, leading to widespread chaos in healthcare services across the country. Similarly, in 2020, the University of California, San Francisco (UCSF) School of Medicine paid a ransom of $1.14 million to regain access to data encrypted by attackers.

These incidents, along with the recent OneBlood attack, underscore the persistent threat of ransomware to the healthcare industry and the urgent need for enhanced cybersecurity measures to protect critical infrastructures. The healthcare sector must prioritize cybersecurity to safeguard not only sensitive data but also the lives and well-being of patients who rely on its services.
