Threat-actor claim — not a regulatory filing

This row is a claim by the ransomware group Karakurt on its public extortion blog. It has not been validated by the victim or any regulator. Treat attribution and counts as the threat actor's assertion until a regulatory filing or victim disclosure corroborates them.

Founded in 1978, McAlester Regional Health Center is devoted to a continuum of care offering a variety of health care services to the citizens of Southeast Oklahoma. Another one medical center doesn't care about their patients' data. 126gb of this organization data includes medical information, personal documents, financial and accounting data and lots of HR documentation. 40gb of DNA tests of patients is a bonus! Stay tuned.
