Equifax Inc said on Thursday it has taken one of its customer help website pages offline as its security team looks into reports of another potential cyber breach at the credit reporting company, which recently disclosed a hack that compromised the sensitive information of millions of people.
The move came after an independent security analyst on Wednesday found part of Equifax's website was under the control of attackers trying to trick visitors into installing fraudulent Adobe Flash updates that could infect computers with malware, the technology news website Ars Technica reported.
"We are aware of the situation identified on the equifax.com website in the credit report assistance link," Equifax spokesman Wyatt Jefferies said in an email. "Our IT and security teams are looking into this matter, and out of an abundance of caution have temporarily taken this page offline."

The Atlanta-based company, which has faced seething criticism from consumers, regulators and lawmakers over its handling of the earlier breach, said it would provide more information as it becomes available.
As of 1:15 p.m. ET, the web page in question said: "We're sorry... The website is currently down for maintenance. We are working diligently to better serve you, and apologize for any inconvenience this may cause. We appreciate your patience during this time and ask that you check back with us soon."
Equifax shares were down 1.4 per cent at $108.97 in afternoon trading.
Randy Abrams, the independent analyst who noticed the possible hack, said he was attempting to check some information in his credit report late on Wednesday when one of the bogus pop-up ads appeared on Equifax's website.
His first reaction was disbelief, he said in an interview with Reuters on Thursday. "You've got to be kidding me," he recalled thinking. Then he successfully replicated the problem at least five times, making a video that he posted to YouTube.
Equifax's security protocols have been under scrutiny since Sept. 7 when the company disclosed its systems had been breached between mid-May and late July.
The breach has prompted investigations by multiple federal and state agencies, including a criminal probe by the U.S. Department of Justice, and it has led to the departure of the company's chief executive officer, chief information officer and chief security officer.
As a credit reporting agency, Equifax keeps vast amounts of consumer data for banks and other creditors to use to determine the chances of their customers' defaulting.
