Today I observe that in the interval between when the credit reporting firm discovered the breach and when the news became public, senior executives dumped stocks in what appears to be an attempt to to trade on insider information:

The sale of nearly $2 million in corporate stock by high-level Equifax executives shortly after the company learned of a major data breach has sparked public outrage that could turn into another hurdle for the credit rating agency.

The sales all occurred before the company publicly reported the breach, a disclosure that quickly sent its stock tumbling. The timing of the sales could attract federal scrutiny, legal experts say, though proving insider trading would be difficult. A company spokeswoman said the executives did not know about the breach when they sold their shares.

………

Equifax, a major consumer credit reporting agency, disclosed Thursday that hackers had obtained sensitive information, including Social Security numbers and dates of birth, for 143 million people. The breach began in May and was discovered by the company on July 29. Shortly afterward, three company executives — Chief Financial Officer John W. Gamble; Joseph M. Loughran III, the president of U.S. information solutions; and Rodolfo O. Ploder, the president of workforce solutions — sold large amounts of their shares of Equifax stock.

Yeah, sure, “The executives did not know about the breach when they sold their shares.”

I believe that.
