Yahoo faces constant queries by legislators, who this week criticized Yahoo for failing to response “a number of basic questions” about the 2 mega breaches.

A spokesperson from Yahoo said, “As we have previously disclosed, our outside forensic experts have been investigating the creation of forged cookies that could have enabled an intruder to access our users’ accounts without a password. The investigation has identified user accounts for which we believe forged cookies were taken or used. Yahoo is in the process of notifying all potentially affected account holders. Yahoo has invalidated the forged cookies so they cannot be used again.”
