More Troubles With Healthcare.gov

Federal cybersecurity officials have flagged HealthCare.gov in a review of websites vulnerable to the Heartbleed computer bug. People with accounts on the insurance enrollment website are being told to change their passwords. Senior administration officials say the warning is made out of an abundance of caution. There's no sign the website has been compromised. The government continues to review federal websites. Cyber officials at the Homeland Security Department say their network has detected hackers trying to exploit Heartbleed. They say they have blocked attempts in many cases. Heartbleed affects sites using the Open SSL encryption technology. Many government sites do not use it.
