Former Yahoo Chief Executive Marissa Mayer at a hearing of the US Senate Commerce, Science and Transportation committee on Wednesday. "Unfortunately, while all our measures helped Yahoo successfully defend against the barrage of attacks by both private and state-sponsored hackers, Russian agents intruded on our systems and stole our users' data." Verizon disclosed last month that a 2013 Yahoo data breach affected all 3 billion of its accounts, compared with an estimate of more than 1 billion disclosed in December. The current and former chief executives of credit bureau Equifax, which disclosed in September that a data breach affected as many as 145.5 million US consumers, said they did not know who was responsible. The Senate Commerce Committee took the unusual step of subpoenaing Mayer to testify on Oct. 25 after a representative for Mayer declined multiple requests for her voluntarily testimony.
