Equifax first disclosed that breach in September.
Embattled Equifax Inc. has moved one of its webpages offline as the company looks into whether hackers tried to breach its systems this week. Equifax said it took the site offline after suspicious activity was detected. "When it becomes available or we have more information to share, we will".
Ars Technica had reported that an independent researcher spotted a credit report assistance page delivering the infected file, which some analysts thought might be tied to an ad network or analytics provider used by the credit reporting agency.
"We are aware of the situation identified on the equifax.com website in the credit report assistance link", said Equifax spokesman Wyatt Jefferies.More news: Commissioner: NFL needs to 'move past' national anthem controversy

Congressman Patrick Henry (R-N.C.) has since introduced legislation that would crack down on Equifax and other credit reporting companies and require them to stop using Social Security numbers.
The breach led to the retirement of Equifax chief executive Richard Smith, who has remained as a consultant to the company during the investigation.
On its website, Equifax's Canadian division says it has not yet mailed out any notices and made clear it would not be making any unsolicited calls or emails about the issue.
The latest hack comes more than a month after the Atlanta-based company announced a massive data breach that has affected as many as 145.5 million people. (Much less on web pages specifically designated to help the victims of previous hacks.) Most companies whose primary goal is to collect and secure highly sensitive (and incredibly lucrative) data invest in, you know, basic security measures.
