"Rx Delays and Fallout: Cyberattacks Disrupt US Healthcare Sector"

Change Healthcare expects the cybersecurity incident to disrupt its operations for at least a day, suspecting a nation-state behind the attack, leading to manual processing of prescriptions at some hospitals and retail pharmacies. The American Hospital Association advises health systems to disconnect from Change Healthcare and Optum, with cybersecurity experts concerned about the broad impact due to the company's responsibility for massive amounts of patient data. The incident, believed to be a result of hackers exploiting vulnerabilities in a remote IT platform, is seen as an attack on the entire healthcare sector, with potential negative credit implications for Optum's parent company, UnitedHealth Group.
