UCLA Health System failed to properly secure its records and quickly notify as many as 4.5 million patients in a recent hacking incident, a new lawsuit contends. A Redlands law firm has filed a lawsuit on behalf of Los Angeles resident Miguel Ortiz, a patient of UCLA since 2011, seeking class-action status on behalf of all current and former patients of the health system. Experts have already criticized UCLA for not encrypting patient data after Anthem Inc. was hacked earlier this year. The vulnerable information contained names, dates of birth, Social Security numbers, health plan identification numbers, and medical information including patient procedures and diagnoses.
