Amgen Data Breach Exposes Patient Health Info

Amgen Inc., a multinational biopharmaceutical company based in California, recently disclosed a data breach that compromised patient protected health information and proprietary company data. The incident occurred in July 2026 when Amgen identified unauthorized activity involving data stored in cloud environments hosted by third-party service providers.

The forensic investigation confirmed that attackers had exfiltrated data from the cloud environments, including sensitive information such as patient protected health information and proprietary company data. 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.

The affected individuals may face an increased risk of medical identity theft and fraud. Edelson Lechtzin LLP, a national class action law firm, is investigating a potential class action to pursue legal remedies on behalf of individuals whose sensitive information may have been compromised in the Amgen breach.
