UnitedHealth has revealed that 190 million Americans had their personal and healthcare data stolen in the Change Healthcare ransomware attack, nearly doubling the previously disclosed figure.

Bleeping Computer on Wednesday also reported that an extortion note the attacker sent to PowerSchool claimed that the personal data of 62.4 million students and 9.5 million teachers was swept up in the breach.
