Earlier this month, Equifax, one of the nation's three key credit-tracking bureaus, disclosed that hackers stole Social Security numbers and other sensitive information for 143 million people.
Equifax said the breach occurred from mid-May to late July, when it was discovered. The executives sold their stock a few days later, in early August.
The company has been swamped with consumers' efforts to freeze their credit profiles in the wake of the data breach, according to consumer experts and people who have tried.
Friday, Equifax announced that two top executives were retiring, but none were among the three who disclosed large stock sales after the data breach.
