THOUSAND OAKS, Calif., Aug. 04, 2026 (GLOBE NEWSWIRE) -- Edelson Lechtzin LLP, a national class action law firm, is investigating data privacy claims arising from the Amgen data breach. Amgen Inc. (Amgen), a California-based multinational biopharmaceutical company, identified unauthorized activity in July 2026 involving data stored in cloud environments hosted by third-party providers, and later confirmed that patient protected health information and proprietary company data had been stolen.
What Happened
In July 2026, Amgen identified unauthorized activity involving data stored in cloud environments hosted by third-party service providers. Amgen activated its cybersecurity response plan, initiated containment measures, and engaged cybersecurity forensic experts to investigate.
The forensic investigation confirmed that attackers had exfiltrated data from the cloud environments, including proprietary company data and patient protected health information. On July 29, 2026, Amgen concluded that the incident is material due to the volume of files that appear to have been involved and the potential sensitivity of the exfiltrated information. Amgen disclosed the breach in a Form 8-K filed with the U.S. Securities and Exchange Commission on July 31, 2026.
Information Exposed
According to Amgen’s public disclosures, the information that may have been compromised in the Amgen data breach includes:
- Patient protected health information (PHI)
- Proprietary and confidential company data
Who May Be Impacted
The Amgen data breach may affect patients whose protected health information was stored in the affected cloud environments. Individuals who receive a data breach notification from Amgen may face an increased risk of medical identity theft and fraud.
