"UnitedHealth Cyberattack Causes Billing Delays and Prescription Access Threats"

UnitedHealth has attributed a disruptive cyber attack affecting healthcare providers to the group Blackcat, causing a week-long outage of its Change Healthcare system and hindering transactions between providers and insurance companies. The breach, which could last for weeks, has prompted the company to set up a loan program for affected healthcare providers. Blackcat, known for previous hacks, has claimed responsibility and allegedly stolen millions of patient records, including sensitive medical and insurance data. The US government has issued a $15 million reward for information on the group, and UnitedHealth is working with cybersecurity firms to address the situation.
