WASHINGTON -- Equifax Inc. has taken part of its website offline after an independent security analyst reported that the site apparently had been hacked. He said clicking a link on the site redirected him to a malicious URL urging him to download malware.
Also Thursday, a top Republican congressman introduced a bill that would stop credit reporting companies such as Equifax from using Social Security numbers to verify Americans' identities.
The potential hack comes a month after Equifax revealed that a data breach exposed the Social Security numbers and birthdates of as many as 145.5 million Americans. That earlier hack took place after Equifax failed for several months to fix a software flaw that federal officials had warned about in March.
Late Wednesday night, security analyst Randy Abrams said in a blog post that while he was trying to download his credit report from the Equifax site, he clicked a link that kicked him to a third-party website with "one of the ubiquitous fake Flash Player Update screens." His post was first reported by technology news site Ars Technica.
As of Thursday morning, that link instead directs users to an Equifax announcement that the page is down for maintenance.
"We are aware of the situation identified on the equifax.com website in the credit report assistance link," an Equifax spokesperson said in a statement. "Our IT and Security teams are looking into this matter, and out of an abundance of caution have temporarily taken this page offline."
Rep. Patrick McHenry, R-N.C., introduced legislation Thursday that would crack down on credit reporting companies. It would require Equifax, Experian and TransUnion to phase out the use of Social Security numbers by 2020.
The legislation also would create a national framework for consumers to freeze access to their credit to prevent identity theft as well as mandating the federal government to create uniform cybersecurity standards for credit reporting companies and conduct onsite examinations.
"The bill I've introduced today takes an important first step in providing meaningful reforms to help Americans who have been impacted by this breach," McHenry said. "It is focused on prevention, protection and prohibition."
The breach revealed last month, and Equifax's bungled handling of its aftermath, led to bipartisan outrage. The company's former chief executive, Richard Smith -- who stepped down after the breach was disclosed -- was slammed by lawmakers in four congressional hearings last week.
