On June 6, 2026, the ransomware group Incransom listed kelmreuter.com on its leak site and published internal files allegedly stolen from Persona Dental, a family-focused dental clinic in Sartell, Minnesota. The breach affects patients whose personal and medical information may have been contained in the exfiltrated documents. Available reporting describes the incident as a ransomware attack in which the group claims to have taken sensitive internal files from the clinic’s systems.

What Public Reporting Shows
Public reporting indicates that Persona Dental was added to Incransom’s disclosure page on June 6, 2026. The clinic provides general, cosmetic, implant, and sleep-apnea dentistry to families in the Sartell area. The data exposed consists of internal files exfiltrated during the ransomware incident. Exact victim counts and the full scope of records remain unconfirmed, as neither the clinic nor the attackers have released a detailed patient list. The leak site link directs visitors to a Tor onion address hosted by the ransomware operators.
Why This Matters for You and Your Family
When a local dental practice is hit, the people most at risk are ordinary patients like you and your family. Appointment records, insurance details, Social Security numbers used for billing, addresses, phone numbers, and email accounts can all appear in stolen internal files. Once that information leaves the clinic’s control, it can be sold, posted, or used to target you with identity theft, phishing, or harassment. Families with children often share the same contact details across accounts, which multiplies the exposure.
The Doxxing and Identity-Chain Implications
Credential leaks from healthcare providers frequently cascade into account takeovers elsewhere. An email and password pair taken from a dental patient portal can unlock your banking, school logins, or social media. Attackers then map those handles to your real identity, creating an identity chain that leads to doxxing. Children’s gaming accounts are especially vulnerable because kids often reuse simplified passwords tied to family email addresses. Public reporting shows these chains move quickly from initial leaks to full personal dossiers sold on underground forums.
