In a letter to the CEOs of Equifax, TransUnion, and Experian, consumer groups are calling on the bureaus to explain their growth in the wake of the Equifax data breach, expressing particular concern that part of this growth is off the back of millions of Americans harmed by the Equifax data breach. To determine whether these companies are profiting from the Equifax data breach, the groups are requesting information on revenues from the sale of identity theft and credit monitoring products in the wake of the breach.
