Five members of AvMed Health Plans filed a class-action lawsuit against the insurer on behalf of 1.2 million people whose personal information may have been leaked in what one attorney describes as one of the biggest medical data breaches in history, the Gainesville Sun reports. The breach involved two laptops that disappeared from a conference room on Dec. 11, 2009. It wasn't until February and June of the following year that the company got around to informing members of the security breach. The lawsuit was filed in the 11th Judicial Circuit in Miami-Dade County by Sarasota law firm Edelson McGuire LLC. Article
