It looks like Obamacare doesn't cover getting infected with the "Heartbleed" bug. HealthCare.gov is telling people who signed up for health insurance at the website to change their passwords to protect against the cyberbug that allows hackers to steal data. A message posted on the website says there's no indication that any personal information has been at risk, but that passwords have been reset out of caution. "Heartbleed" is believed to affect two out of three web servers. It has forced companies from Amazon.com to Yahoo to take steps to protect themselves against the bug.
