Change Healthcare has hidden its data breach notification webpage from search engines using “noindex” code, TechCrunch found, making it difficult for affected individuals to find information about the massive healthcare data breach that compromised over 100 million people’s medical records last year.

The UnitedHealth subsidiary said Tuesday it had “substantially” completed notifying victims of the February 2024 ransomware attack. The cyberattack caused months of healthcare disruptions and marked the largest known U.S. medical data theft.
