- The company has already been reeling from a breach that exposed the personal information of 145.5 million people.
- Equifax said it has disabled a customer help webpage while its security teams investigate.
Equifax shares dropped 3 percent Thursday after it said it has disabled one of its customer help online pages and is investigating another possible cyberbreach.
The consumer credit reporting company said its security teams are looking into another possible breach barely one month after it disclosed a hack that left exposed the personal information of 145.5 million people.
The company said the problem is in its credit report assistance link on its website. "We are aware of the situation," a spokesman said. "Our IT and Security teams are looking into this matter, and out of an abundance of caution have temporarily taken this page offline."
Earlier this month, Equifax said its outside security consultant had concluded an investigation into the breach, which it first detected in July. It identified more than 2 million more people were affected than originally estimated. The hack has led to multiple federal and state investigations and the departure of the company's 12-year chief executive.
The company has said that it was warned to be prepared for further cyber attacks once word of the giant breach got out.
An independent security analyst told the website Ars Technica that he noticed the latest problem when he went to Equifax's site on Wednesday and found out visitors were redirected to download a fraudulent software update.
Shares of Equifax were down 2.3 percent at around 1 p.m. ET.
