P**g**s***e O*al S**g**y & I**la**ol**y Listed by nightspire Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Pegasus Oral Surgery & Implantology was listed by the nightspire ransomware group on April 27, 2026, after internal files were exfiltrated. Anyone who has received care from the practice should check for any notifications and monitor their accounts and records.
What happened
The only confirmed information is the April 27, 2026 listing itself. It references exfiltration of internal files during a ransomware incident. No further details on timing, attack method, volume of data, or confirmation of encryption have been released. The affected organization has not issued a public statement on the event.
The group behind it: nightspire
Nightspire is a ransomware operation that maintains a leak site to list victims and, in some cases, to publish stolen material. The group claims responsibility for the listing of P**g**s***e O*al S**g**y & I**la**ol**y. Public reporting on the actor describes typical ransomware tactics that include network intrusion followed by data exfiltration and encryption demands. No independent verification of the specific claims made in this listing has been established.
P**g**s***e O*al S**g**y & I**la**ol**y and its sector
P**g**s***e O*al S**g**y & I**la**ol**y operates in the dental and oral surgery sector, providing specialized surgical and implant services. Organizations of this type maintain internal records related to clinical operations, scheduling, and patient interactions. A breach at such a provider can expose operational material that is not normally public, regardless of whether patient records were directly involved.
What data was at risk
The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of file types or data categories has been published. Exact contents therefore remain unconfirmed.
Why it matters
Even limited disclosure of internal operational files can create follow-on risks for the organization and any individuals referenced in those files. Without Reported Details on the material, the practical impact on specific people cannot be quantified at this time. Organizations in healthcare-adjacent fields hold information that may be targeted for further misuse if it becomes accessible.
What to do if you're exposed
Individuals who believe their information may be involved should monitor official statements from the organization and follow any guidance it issues. Basic protective steps include changing passwords for any associated accounts and enabling multi-factor authentication where available.
- Review account activity for unusual access.
- Contact the organization directly for any patient-specific notifications.
- Run a free exposure scan of your email address against known breach data sets to check for prior appearances.

Publicly posted by nightspire — 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.
