Flint Hills Dialysis

Flint Hills Dialysis was compromised in a ransomware attack attributed to insomnia in December 2025. The organization, operating in the Healthcare sector in United States, was added to the group's data leak site as part of an extortion campaign.

insomnia operates as a financially motivated ransomware-as-a-service (RaaS) operation, exfiltrating sensitive data and threatening public disclosure to pressure victims into paying ransom demands.

Flint Hills Dialysis focuses on dialysis and chronic kidney disease management, creating personalized treatment plans to improve patients' lives. With clinics in Manhattan and Marysville, Kansas, their team emphasizes patient education and compassionate care.
