The healthcare data of a vast number of Americans is potentially compromised following a ransomware attack on Change Healthcare, a subsidiary of UnitedHealth Group. The attack, which crippled a significant portion of the US healthcare system, has raised serious concerns about data security and patient privacy.
While the exact number of affected individuals remains unclear, Change Healthcare acknowledged the potential impact on "a substantial proportion of people in America." The company's lack of transparency regarding the scope of the data breach has further heightened anxieties.
