Hackers have stolen the personal information and medical records of more than 3.75 million people in a data breach at health data giant CareCloud, the company has confirmed with federal regulators. The disclosure marks the first confirmation of the scale of the data breach, which is now confirmed to be the fifth-largest theft of health data in 2026 so far.
CareCloud detailed the March data breach in a filing with the Department of Health and Human Services (HHS) on Monday. The number of affected victims was reportedly revised up in an update on Tuesday, though it’s unclear if the figure is expected to rise further.
