Park Dental Research Listed by interlock Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Park Dental Research has been listed by the interlock ransomware group, which claims to have exfiltrated internal files in an attack. The incident was disclosed on May 11, 2026, affecting an undisclosed number of people; anyone who may have shared data with the organization should check for notifications and monitor their accounts.
On May 11, 2026, the ransomware group interlock listed Park Dental Research on its leak site. The listing states that internal files were taken during a ransomware operation. The number of individuals affected remains unknown, and no independent confirmation of the data's contents or volume has been made public.
The incident matters because Park Dental Research supplies technologies and materials to dental laboratories and orthodontic clinics. Any exposure of records held by such a supplier can affect partner organizations and their patients even when the scale of the breach is still unclear.
Breaking down the breach
The only confirmed public detail is the May 11, 2026 listing by interlock. The group states that files were exfiltrated during a ransomware attack. No information has been released about the date of the intrusion, the method of initial access, the volume of data taken, or whether any data was later published.
Park Dental Research has not issued a public statement on the matter. The number of records involved and the identities of any affected individuals or partner organizations remain undisclosed.
Inside interlock
Interlock is a ransomware operation that follows the double-extortion model common among current groups. It typically encrypts systems and removes copies of data, then lists victim names on a leak site to pressure payment. The group’s public claims about any specific victim, including the description of data types, are unverified assertions made on its own platform.
Prior public reporting on interlock has documented similar listings against organizations in manufacturing and professional services. No additional claims specific to Park Dental Research beyond the May 2026 listing have been independently corroborated.
Who is Park Dental Research?
Park Dental Research provides materials and equipment used by dental laboratories and orthodontic clinics. Organizations in this sector routinely hold records that include client account details, order histories, and technical specifications for medical devices.
A compromise at a supplier can therefore reach beyond the company itself, touching downstream clinics and the individuals whose treatment information appears in those records.
What was likely exposed
The interlock listing asserts that internal files were removed. The group further claims that partner and customer data, financial documents, and login credentials were among the material made available. These descriptions originate solely from the threat actor and have not been confirmed by Park Dental Research or any external investigation.
Because the precise contents of the exfiltrated files have not been disclosed, the exact categories of personal or business information that may have been taken remain unconfirmed.
Why it matters
Even without a confirmed count of affected individuals, the exposure of records from a dental-industry supplier can create downstream risks. Clinics that rely on the supplier may face questions about the security of their own ordering and patient-related systems. Individuals whose information appears in those records could see increased attempts at account misuse or targeted fraud.
For the organization, the incident adds operational and legal questions typical of ransomware events, including potential notification obligations and the cost of restoring systems and reviewing third-party access.
What to do if you're exposed
Individuals who have done business with Park Dental Research or its partner clinics can take several immediate steps to limit possible harm.
- Monitor bank and credit accounts for unusual activity and place fraud alerts if warranted.
- Change passwords for any accounts that may share credentials with systems connected to the supplier.
- Review statements from dental providers for any unexpected access or changes.
- Run a free exposure scan of your email address against known breach data to check for additional appearances.

Publicly posted by interlock — unverified claim, pending independent verification
Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
