csd-drancy.com Listed by lockbit5 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
CSD-drancy.com was listed by the LockBit5 ransomware group on December 25, 2025, after internal files were exfiltrated in a ransomware attack. The number of people affected is undisclosed; individuals should check whether their data has been compromised and take appropriate protective steps.
Inside the incident
The only confirmed information is the listing itself. The group claims internal files were taken from csd-drancy.com, but the volume of data, the method of initial access, and whether encryption was also deployed are not disclosed. No statement from the organization has been made public, and independent verification of the claim has not been reported.
Inside lockbit5
LockBit is a ransomware operation that has been active for several years and is known for encrypting systems and publishing stolen data when ransom demands are not met. The group maintains a leak site where it lists claimed victims and sometimes releases samples of data. Its tactics typically include exploiting remote access services, phishing, or vulnerabilities in public-facing applications. Prior activity attributed to the group has involved healthcare providers, manufacturers, and public-sector entities, though each incident requires separate confirmation.
About csd-drancy.com
The domain corresponds to CENTRE DE SANTE DENTAIRE NOTRE ENGAGEMENT, a dental health center. Organizations of this type maintain appointment records, patient histories, treatment notes, and administrative files. A claim of access to such an organization is consequential because dental practices routinely process personal and health-related information that can remain sensitive over long periods.
What was likely exposed
The listing refers only to “internal files exfiltrated.” The precise categories of data have not been confirmed. Dental centers commonly store patient identifiers, contact details, medical histories, insurance information, and billing records, yet the exact contents of any exfiltrated material remain unverified.
The real-world impact
Individuals whose information appears in the exfiltrated files could face risks of identity misuse or targeted scams if the data later circulates. For the organization, the incident may result in regulatory scrutiny, costs related to investigation and notification, and loss of trust among patients. Both outcomes depend on the actual data involved, which has not been specified.
What to do if you're exposed
Monitor statements from the dental center and any official notifications that may follow. Review bank and insurance statements for unusual activity and consider placing fraud alerts with credit agencies if personal identifiers are involved. Readers can run a free exposure scan of their email address to check whether their information has appeared in known breach data.
- Change passwords for any accounts linked to the organization and enable multi-factor authentication.
- Watch for unsolicited communications that reference personal or treatment details.
- Contact the center directly with questions about the incident and any steps it is taking.

Publicly posted by lockbit5 — 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.
