Equifax said David Webb, its chief information officer, is being replaced by Mark Rohrwasser, who joined Equifax in 2016 and has led Equifax International IT operations since that time.
Susan Mauldin, the company's chief security officer, is being replaced by Russ Ayres, who has been appointed to that position on an interim basis. Mr. Ayres most recently served as vice president of IT at Equifax. Mr. Ayres will report directly to the CIO.
The company said the personnel changes were "effective immediately."
The move comes in the wake of the breach that compromised vital personal information of potentially 143 million Americans, including dates of birth and social security numbers. The company said its internal investigation of the breach is ongoing and that it continues to work closely with the Federal Bureau of Investigations.
The breach has shaken the trust of the public and lenders in the ability of one of the largest credit-reporting companies to safely store and manage consumers' data.
In addition, Equifax, in a progress update about the hack, confirmed on Friday that it had hired Mandiant, the cyber investigations division of FireEye Inc., which was previously reported by The Wall Street Journal. The company also further specified when the intrusion into its systems took place, saying it believed it happened between May 13 and July 30.
