What Happened?

On September 1, 2026, El Camino Health (“El Camino”) identified unusual activity in its Microsoft 365 system. El Camino immediately took steps to secure the system and initiated an investigation with the assistance of third-party forensic experts. The investigation determined that there was unauthorized access to the Microsoft 365 accounts of four El Camino employees over the period of August 26, 2026, to September 2, 2026. During this time, certain documents were copied or downloaded from the compromised accounts. El Camino then undertook a review and analysis of these documents to determine what information they contained. This review is ongoing.

On October 30, 2026, El Camino Health began mailing notification letters to patients whose information was involved in the breach. El Camino has notified the California Attorney General of the data breach and has posted a public notice of the breach on its website. Once El Camino’s review is complete, it will mail notification letters to any additional patients it identifies as affected by the breach.
