U.S. Sen. Mark Warner, D-Virginia, called Monday for the Securities and Exchange Commission to investigate whether Yahoo Inc. satisfied its securities disclosure obligations after becoming aware of a 2014 hack affecting a half-billion user accounts.
In a letter to SEC Chairwoman Mary Jo White, Warner noted the questions surrounding when senior executives became aware of the breach, which Yahoo disclosed Sept. 22 and blamed on a “state-sponsored actor.” News reports have indicated that Yahoo executives might have learned of the breach a couple of months earlier in July, the same month that Verizon announced a $4.8 billion takeover of the company’s core business.
