The California-based biotechnology company Amgen said patient information and proprietary company data was stolen from cloud systems operated by third-party providers. The investigation found that attackers exfiltrated company information, including proprietary data, patients' protected health information, and other sensitive records. Amgen said it has not identified any disruption to its products, manufacturing operations, financial reporting systems, or its ability to supply medicines to patients. The investigation remains ongoing, and Amgen said it is still assessing whether confidential business information, intellectual property, research and development data, or additional patient information was accessed or stolen. Amgen did not disclose how the attackers gained access to the cloud environments or identify the affected cloud providers.
