UnitedHealth Group experienced a ransomware attack on February 21, which disrupted their services including medical claim handling and revenue cycle services. This resulted in severe delays in processing claims, pushing healthcare providers towards financial distress, with some nearly facing bankruptcy. The attack by the group BlackCat forced UnitedHealth to rebuild services and affected providers have started filing lawsuits due to not maintaining adequate cybersecurity measures, with allegations of sensitive information leaks. UnitedHealth has paid over $2 billion to affected providers and the data compromised in the attack remains undisclosed.
