Luck didn't improve much for the health-care sector in 2016, following up on a tough year for data breaches. In January, multi-line health-care enterprise Centene announced that 950,000 members had potentially been impacted by a data breach. The breach was caused by the loss of six hard drives that included personal health information on members who had had lab services between 2009 and 2015. It also included names, addresses, dates of birth, Social Security numbers, ID numbers and other health information, the company said. It is not clear if the device was encrypted.
