The major data breach at Yahoo that occurred back in 2013 didn’t affect 1 billion accounts as it was previously said. Yahoo parent company Verizon announced on Tuesday the breach actually affected all 3 billion accounts.
The massive security breach at Yahoo is already known as the largest data breach ever. Last year, it was revealed the breach affected 1 billion accounts. But, on Tuesday, the company has announced the breach has affected not 1, but 3 billion accounts. In other words – all the accounts were impacted by 2013 breach.
The company said that it has sent emails in order to give notice to additional accounts impacted by the breach.
“Yahoo is providing notice to additional user accounts affected by an August 2013 theft of user data previously announced by the company in December 2016. This is not a new security issue. In 2016, Yahoo previously took action to protect all user accounts.”, it reads on Yahoo 2013 Account Security Update FAQs page.
The hackers stole various information, including names, email addresses, phone numbers, etc. However, passwords, card data and bank info were not stolen.
Yahoo was acquired by Verizon and merged with AOL and it is now the part of Oath. Verizon acquired Yahoo for $4.5 billion, $350 million less than the initial offer due to the data breach.
The company says that during the integration it obtained new intelligence and now believes that all Yahoo user accounts were impacted by the 2013 theft.
“Verizon is committed to the highest standards of accountability and transparency, and we proactively work to ensure the safety and security of our users and networks in an evolving landscape of online threats,” said Chandra McMahon, Chief Information Security Officer, Verizon. in a blog post.
“Our investment in Yahoo is allowing that team to continue to take significant steps to enhance their security, as well as benefit from Verizon’s experience and resources.”, she added.
