Summary of article from CNBC, by Ashley Capoot:
UnitedHealth Group confirmed the company paid a $22 million ransom after hackers breached its subsidiary, Change Healthcare, affecting the healthcare sector broadly. The breach left many doctors unable to fill prescriptions or get paid for their services temporarily. Witty revealed that the cybercriminals accessed Change Healthcare through a server that lacked multi-factor authentication, a security measure now implemented across all UnitedHealth’s external-facing systems. The breach compromised files containing protected health information and personally identifiable information, with a data review ongoing. UnitedHealth is working with regulators to assess the breach and notify affected individuals, while also implementing measures to prevent future cyberattacks.
