Yahoo says that all its 3 billion users were affected by the 2013 Cyber Attack


Yahoo, which stands as one of the top web services giants in the world has now disclosed that all its 3 billion users were affected by the 2013 cyber attack. The company made an official statement yesterday on this issue and added that the additional 2 billion data theft victims came to light as Yahoo was being acquired by Verizon in June for $4.5 billion.

The company issued a statement yesterday in which it specifically highlighted the fact that the August 2013 theft impacted all its 3 billion users unlike 1 billion which was reported by media earlier.

As per the sources of Cybersecurity Insiders, Verizon launched an investigation on this issue as soon as it disclosed its intentions to acquire Yahoo via media. It was during this time that it came to know about the exact number of Yahoo users who were impacted by the cyber attack. And so Verizon asked Yahoo’s CEO Marissa Mayer for a discount based on the report compiled by a third party forensic experts.

According to Daily Mail, the leaked info did not contain passwords, payment card data and bank account info in clear text as all this leaked info was in an encrypted format.

The official statement released by Yahoo yesterday says that it would send email notifications to the additional affected user accounts by this month end.

Meanwhile, Verizon declared that it is committed to the highest standards of accountability and transparency. And added that its investment in Yahoo will allow the team to continue to take significant steps to enhance their security and take benefit from Verizon’s vast experience and resources.
