OneBlood, a prominent blood-donation nonprofit, has revealed that sensitive donor information was stolen during a ransomware attack that occurred last summer.
The organization first acknowledged the cyberattack on July 31, 2024, reporting that ransomware operators had encrypted its virtual machines. This forced OneBlood to rely on manual operations, disrupting its ability to collect, test, and distribute blood. The incident caused delays that triggered critical blood shortage protocols in some healthcare facilities across the United States.
As a key supplier of blood to over 250 hospitals nationwide, OneBlood issued an urgent plea for O Positive, O Negative, and Platelet donations at the time, given their universal compatibility for emergency transfusions.
Investigation Details Confirm Data Theft
In recent updates, OneBlood began notifying affected individuals following the completion of its internal investigation on December 12, 2024. According to the findings, unauthorized access to its systems occurred between July 14 and July 29, 2024, with threat actors exfiltrating specific files and folders.
The organization’s notification clarified, “Our investigation determined that between July 14 and July 29, 2024, certain files and folders were copied from our network without authorization.” These files contained personally identifiable information (PII), including donors’ names and Social Security numbers.
Fortunately, the stolen data does not appear to include additional details such as contact information, demographic data, or medical history typically collected during blood donations. However, the exposure of names and SSNs poses a significant risk for identity theft and financial fraud, as these details are difficult to change and can be misused for years.
Mitigation Measures for Affected Donors
To address these risks, OneBlood is offering free one-year credit monitoring services to affected individuals. Activation codes for this service have been included in the breach notification letters, which must be redeemed by April 9, 2025.
Additionally, impacted donors are encouraged to implement credit freezes and fraud alerts on their financial accounts to protect against potential misuse of their information.
Concerns Over Delayed Notifications
While OneBlood has fulfilled its commitment to inform donors of potential data exposure, the six-month delay in notification has raised concerns about the extended period of vulnerability for affected individuals.
The exact number of donors impacted by this ransomware attack remains undisclosed, leaving the scale of the breach uncertain.
Broader Implications
This incident highlights the critical need for robust cybersecurity measures in the healthcare sector, particularly for organizations handling sensitive donor and patient information. The breach serves as a stark reminder of the far-reaching consequences of ransomware attacks and the importance of timely responses to protect those at risk.
