Blue Shield California’s Google Ads Data Leak Exposes 4.7 Million
Blue Shield of California inadvertently exposed the sensitive data of 4.7 million individuals to Google Ads via a misconfigured Google Analytics account for nearly three years. The exposed data included names, medical information, and account details. This data sharing, which ceased in January 2024, violated prior warnings from federal agencies against such tracking practices. The breach follows other recent healthcare data compromises, highlighting ongoing vulnerabilities in the sector.
