Federal prosecutors are investigating stock sales by three Equifax executives in early August, just days after the company discovered a data breach affecting the personal information of up to 143 million people.

The criminal probe, looking at whether the executives had violated insider trading laws, was reported by Bloomberg News, citing people familiar with the investigation. Equifax didn't respond to a CNBC request for comment.
