Yahoo Still Unsure How 3 Billion Accounts Were Hacked
It was a tough week for former Yahoo CEO Marissa Mayer (pictured) who was grilled by U.S. senators this week about the 2013 security breach that exposed 3 billion Yahoo accounts – and admitted that Yahoo is still in the dark about exactly how the hack was pulled off.
While Yahoo initially said that some 1 billion accounts were exposed in the breach, Yahoo, which is now owned by Verizon, revealed last month that all 3 billion Yahoo accounts were affected by the breach.
"We worked hard over the years to earn our users' trust. As CEO, these thefts occurred during my tenure, and I want to sincerely apologize to each and every one of our users," Mayer said in her testimony to the Senate Committee on Commerce, Science and Transportation, according to published reports by CNBC and other media.
Mayer blamed "criminal state-sponsored attacks" for the breach and four individuals, including two Russian intelligence agents, have been indicted in connection with the attack. But, shockingly, Mayer said that Yahoo still isn't sure how the attack was carried out.
"To this day we have not been able to identify the intrusion that led to this theft," Mayer said. "We don't exactly understand how the act was perpetrated. That certainly led to some of the areas where we had gaps of information."
