OneBlood ransomware attack disrupts blood supply, donor data stolen
US blood supplier OneBlood suffered virtual machine encryption and system outages in a ransomware attack in July 2024. The switch to manual processes delayed blood collection, testing and distribution and sharply reduced operational capacity. A subsequent investigation confirmed that the attackers accessed the network and copied files from July 14 to 29, and that donors' names and Social Security numbers were also stolen.
