Amgen Data Breach Exposes Corporate and Patient Information
Pharmaceutical company Amgen has disclosed a data breach that compromised sensitive corporate and patient information stored in third-party cloud systems. The breach, which was detected on July 3, 2026, resulted from unauthorized access to proprietary data, patient protected health information, and other sensitive information.
The investigation, led by Amgen with the assistance of external cybersecurity experts, confirmed that attackers exfiltrated data from compromised cloud environments operated by third-party service providers. The company has not revealed the identity of the affected third-party providers or the method of compromise.
Amgen is still assessing the full scope of the breach and evaluating legal and regulatory notification requirements for affected patients. While the company does not currently anticipate a material impact on its financial condition, it is taking steps to prevent similar incidents in the future.
