Yahoo's Ex-CEO Mayer Calls Out Russian Hackers

Marissa Mayer today publicly apologized for two massive data breaches at Yahoo during her tenure as CEO of the company, and blamed Russian nation-state hackers for their infiltration of the systems.

"As CEO, these thefts occurred during my tenure, and I want to sincerely apologize to each and every one of our users," she said in her testimony to the Senate Commerce Committee, according to a Reuters report.

"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," she said.

The breaches at Yahoo compromised all 3 billion user accounts with the email and services provider. Mayer left the firm after Verizon acquired it in June. Federal officials in March indicted two Russian government FSB officers as well as two infamous Russian cybercriminals for their roles in Yahoo's hack as well as other related cyberattacks.
