UnitedHealth Group and Change Healthcare have acknowledged significant cyberattacks affecting a vast number of Americans. UnitedHealth Group admitted, two months after the data breach, that the breach involved protected health information (PHI) and personally identifiable information (PII) potentially impacting a substantial proportion of the U.S. population. Similarly, Change Healthcare conceded to paying a $22 million bitcoin ransom to hacker group AlphV six weeks post-attack, with ongoing risks of losing more customer data. The cyberattacks, which occurred earlier this year, have disrupted medical services nationwide, affecting payment and insurance claims processing and causing considerable strain on healthcare systems.
