Change Healthcare

Change Healthcare suffered a significant cyber-attack impacting approximately 190 million individuals, a number revised from an earlier report of 100 million in July. As a major healthcare payment processing firm in the US, the breach's scale and the sensitive nature of the compromised data classify it as one of the most severe healthcare data breaches in 2024. The financial repercussions are substantial, with estimated costs reaching $3.1 billion. ALPHV/Blackcat ransomware group has been implicated in the breach. The incident has led to multiple lawsuits against UnitedHealth Group, Change Healthcare's parent company.
