Southern Illinois Dermatology Listed by Insomnia Ransomware Group

On November 28, 2025, Southern Illinois Dermatology appeared on the leak site of the insomnia ransomware group after the attackers exfiltrated internal files from the medical practice.

What Public Reporting Shows

Public reporting indicates the dermatology group, which operates 15 locations across the region and was founded in 1996, had internal files stolen during a ransomware incident. The data exposed consists of internal files; the precise volume and exact contents remain unclear from available reporting. No confirmed victim count has been released, leaving patients, employees, and anyone whose records were stored in those systems uncertain about their exposure. The listing appeared on the group’s onion leak site, which is tracked by ransomware monitoring services such as ransomware.live.

Industry research from sources such as DoxxScan™ continuous monitoring indicates that healthcare organizations remain frequent targets because patient records contain names, dates of birth, Social Security numbers, addresses, and clinical details that retain value on the underground market long after the initial breach.

Why This Matters for You and Your Family

When a local medical provider loses control of internal files, the information can surface in ways that directly affect your daily life. Medical records often include phone numbers, insurance details, and family member names that can be combined with other leaked data to impersonate you at banks, government agencies, or pharmacies. For families, a single breach can expose children’s information if they were patients or if parent-guardian linkages exist in the files. The November 28, 2025 listing means the clock is already running on how quickly that data spreads across forums and dark-web marketplaces.
