Health care site flagged in Heartbleed review

People with accounts on the enrollment website for President Barack Obama's signature health care law are being told to change their passwords following an administration-wide review of the government's vulnerability to the confounding Heartbleed computer virus.

Senior administration officials say there is no indication that the HealthCare.gov site has been compromised and the action is being taken out of an abundance of caution. The officials say the government's Heartbleed review is ongoing and users of other websites may also be told to change their passwords in the coming days.

The Heartbleed computer bug has caused major security concerns across the Internet and affected a widely used encryption technology designed to protect online accounts.

The officials insist on anonymity because they are not authorized to discuss the security review by name.
