In April 2015, the company discovered the breach as part of a security review that found hackers had gained access to a database that members use to get access to the company's website and services.
1.1 million members had their names, birth dates, email addresses and subscriber information compromised, but member password encryption prevented the attackers from gaining access to Social Security numbers, medical claims, employment, credit card and other financial data.
The company has petitioned the Supreme Court to hear its data breach case highlighting questions over harm.
