Summary

Hide ▲

DaVita's dialysis labs data was leaked on a dark web portal, exposing sensitive patient and health information tied to nearly 2.7 million people. The leaked set was described as roughly 1.5 terabytes across nearly 700,000 files, including patient records, insurance details, user account information, and financial data. The exposure also included some tax identification numbers and images of personal checks. The leak matters because the stolen material was later verified and prompted patient notifications and credit-monitoring support.
