A newly discovered data breach exposed the private information of more than 1 billion Yahoo users, the company said, dwarfing the scope of another recently disclosed hack and casting doubt on Verizon Communications Inc.’s planned acquisition of the internet company.
The 2013 theft is separate and twice as large as a 2014 hack that Yahoo Inc. disclosed earlier this year. That hack had been billed as likely the largest-ever theft of personal data.
Unidentified hackers penetrated Yahoo’s network in August 2013 and stole data including names, email addresses, telephone numbers, dates of birth and passwords, the company said. Yahoo said it believes the incident is distinct from the 2014 hack, and that the hackers are no longer in its corporate network.
The new disclosure could jeopardize Verizon’s $4.83 billion acquisition of Yahoo’s core internet business, a deal announced in July and expected to close in early 2017. In October, Verizon signaled it could consider the 2014 breach a material event that could allow it to change the deal terms.
