Former Yahoo CEO – Marissa Mayer

Former Yahoo CEO Marissa Mayer apologised for a pair of massive data breaches at the internet company, blaming Russian agents, at a hearing on the growing number of cyber attacks involving major U.S. companies.

“As CEO, these thefts occurred during my tenure, and I want to sincerely apologise to each and every one of our users,” she told the Senate Commerce Committee, testifying alongside the interim and former CEOs of Equifax and a senior Verizon Communications executive.

“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, the largest U.S. wireless operator, acquired most of Yahoo’s assets in June, the same month Mayer stepped down.

Verizon disclosed last month that a 2013 Yahoo data breach affected all three billion of its accounts, compared with an estimate of more than one billion disclosed in December.
