Southern Illinois Dermatology

Southern Illinois Dermatology was compromised in a ransomware attack attributed to insomnia in November 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.

Southern Illinois Dermatology, founded in 1996 by Board-Certified Dr. Ted G. Van Acker, has grown from one office to 15 locations. We offer general, surgical, cosmetic dermatology and advanced laser treatments with attentive, professional care.
