The federal government stored sensitive personal data of millions of people who purchased insurance through ObamaCare on a network with basic cybersecurity flaws, a federal audit revealed Thursday. HealthCare.gov relies on a $110 million digital repository called MIDAS to store the information it collects. The system was apparently breached by hackers last summer, though according to reports, no consumer information was viewed or taken. A 2014 report from the Government Accountability Office said that health officials failed to implement best practices across the entire system, leaving small weaknesses that place sensitive information at risk.”]
