In July 2026, Partnered Health, an Australian network of more than 60 general practice and skin‑cancer clinics, reported that a malicious actor accessed its systems on 23 June, compromising personal and clinical information for patients at dozens of locations. The breach was reported to Australian authorities, an injunction was obtained to block use of the stolen data, and the provider began working with Services Australia and cybersecurity specialists to assess the impact.

In August 2026, Amgen disclosed that hackers had penetrated third‑party cloud services used to store protected patient health information. The company filed a material breach report (Form 8‑K) with the U.S. SEC, activated its cyber‑response plan, engaged independent forensic experts and started notifying regulators and affected individuals. Amgen said the incident did not affect product supply, manufacturing, financial reporting or its ability to meet patient needs. The breach underscores Amgen’s reliance on external cloud vendors and arrives amid heightened regulatory scrutiny of its rare‑disease drug Tavneos following a retracted study.

Both incidents illustrate growing cybersecurity challenges in the health sector across jurisdictions, prompting tighter regulatory oversight and calls for stronger data‑protection measures.
