WASHINGTON (AP) — People who have 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. A message that will be posted on the health care website starting Saturday reads: "While there's no indication that any personal information has ever been at risk, we have taken steps to address Heartbleed issues and reset consumers' passwords out of an abundance of caution." The health care website became a prime target for critics of the Obamacare law last fall when the opening of the insurance enrollment period revealed widespread flaws in the online system. "We will continue to focus on this issue until government agencies have mitigated the vulnerability in their systems," Phyllis Schneck, DHS deputy undersecretary for cybersecurity and communications, wrote in a blog post on the agenda website.
