Healthcare technology giant CareCloud has confirmed that a data breach earlier this year impacted more than 3.75 million people, making it one of the largest healthcare data incidents disclosed this year.
The New Jersey-based company, which provides electronic health record (EHR) and practice management services, first flagged the intrusion in an SEC filing back in March, but the true scope only became clear this month when the Department of Health and Human Services (HHS) breach tracker updated the affected total from roughly 345,000 to 3,756,469 individuals.
CareCloud says an unauthorized third party accessed one of its Amazon Web Services (AWS) environments between March 10 and March 16, 2026. The intrusion caused an eight-hour disruption to one of the company’s six EHR environments before systems were restored that same evening. During a forensic investigation, CareCloud determined that the attacker claimed to have exfiltrated data from databases within that environment.
The stolen data reportedly includes both identity and medical information:
Full names, postal addresses, and dates of birth
