Yahoo reveals new hack, this time a billion-plus usersDecember 15, 2016 08:19
Yahoo said personal data from over a billion users was stolen in a hack dating back to 2013 -- twice as big as another breach disclosed just three
In a huge blow to the struggling internet pioneer, Yahoo yesterday said it made the discovery as it was investigating what was already the largest data breach of a single company.
"Yahoo believes an unauthorised third party, in August 2013, stole data associated with more than one billion user accounts," it said in a statement.
Yahoo said this case "is likely distinct from the incident the company disclosed on September 22, 2016" affecting 500 million users.
The news poses a fresh threat to Yahoo's deal to sell its core operating assets to Verizon for $4.8 billion.
