Who is nightspire?

Excel Institute for Clinical Research LLC and its sector
Excel Institute for Clinical Research LLC conducts clinical trials and related medical research. Organizations in this sector collect and store participant records, medical histories, laboratory results, and regulatory documentation required for drug and treatment studies. A breach at such an entity can affect both the privacy of research participants and the integrity of ongoing studies.
What data was at risk
The listing refers only to “internal files.” No inventory of specific data types has been published. Organizations of this kind typically hold patient identifiers, contact details, medical records, and study documentation, but the exact contents of any exfiltrated material remain unconfirmed.
The real-world impact
Individuals whose records appear in clinical research files face the possibility of their personal and health information circulating among unauthorized parties. For the organization, the incident may complicate regulatory compliance obligations and require extended forensic review. No financial loss figures or patient notification counts have been disclosed.

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.
