Data breach at Connecticut’s Yale New Haven Health affects over 5 million

Yale New Haven Health disclosed a March cyberattack that exposed personal and healthcare-related information for over 5.5 million people — potentially including names, dates of birth, postal and email addresses, phone numbers, race/ethnicity, Social Security numbers, and medical record numbers. The organization says the attack appears sophisticated and may be related to ransomware or data-extortion, though no group has publicly claimed responsibility and the investigation is ongoing.
