Equifax admits it had another breach 5 months before the one it disclosed

Michael Riley , Anita Sharpe , and Jordan Robertson report:

Equifax Inc. learned about a major breach of its computer systems in March — almost five months before the date it has publicly disclosed, according to three people familiar with the situation.

In a statement, the company said the March breach was not related to the hack that exposed the personal and financial data on 143 million U.S. consumers, but one of the people said the breaches involve the same intruders.
