Healthcare.gov says there is no evidence that their system has been compromised. The site holds information about each person that has logged into the site. That information is considered protected and private information. This includes social security numbers and financial information of each user that created a user name. Healthcare.gov is now asking all that visited the website to change their passwords now. The concern is the risk of the Heartbleed virus becoming an issue for the site in the future.
Virus protection is not always a 100 percent guarantee our computers won't be compromised. It seems the day is coming we will have to "insure" against cyber attacks.
