Nebraska has filed a lawsuit against Change Healthcare, alleging that the healthcare provider's inadequate cybersecurity measures led to a data breach affecting over 100 million Americans. The lawsuit, initiated by Nebraska Attorney General Mike Hilgers, claims that hackers associated with the Russian ransomware group ALPHV accessed the company's network using the credentials of a low-level employee, which were reportedly shared on Telegram. The breach is said to have occurred in February, exposing sensitive medical information of millions of patients. This legal action underscores growing concerns over cybersecurity in the healthcare sector, particularly regarding data protection and ransomware vulnerabilities.
