On 05 August 2024, OneBlood disclosed ransomware issues under the banner "OneBlood Ransomware Attack Disrupts Blood Supply Operations".
OneBlood, a nonprofit blood donation center serving hospitals across the southeastern U.S., experienced a ransomware attack on July 29 that crippled its systems.
The disruption is felt across the environment, affecting critical software systems, electronic donor registration, automated labeling of blood products.
In response, teams activated the incident response plan, and began remediation that includes restoring critical software in reduced capacity, manual labeling of blood products, electronic donor registration, while recovery efforts such as collaborating with other blood centers to replenish inventory, prioritizing blood supply maintenance continue.
The case underscores how ongoing, with advisories going out to stakeholders covering urgent need for O positive, O negative, and platelet donations due to blood supply strain.
Finally, we try to match the incident with the MITRE ATT&CK framework to see if there is any correlation between the incident and the MITRE ATT&CK framework.
The MITRE ATT&CK framework is a knowledge base of techniques and sub-techniques that are used to describe the tactics and procedures of cyber adversaries. It is a powerful tool for understanding the threat landscape and for developing effective defense strategies.
