Yahoo says 1 billion accounts hacked, data stolen in 2013
WASHINGTON Yahoo said that personal data from over a billion users was stolen in a hack dating back to 2013 - twice as big as another breach disclosed three months ago.
Yahoo said on Wednesday that 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.
It said this case "is likely distinct from the incident disclosed on Sept 22, 2016", which affected 500 million users.
Last month, Yahoo disclosed that as part of its investigation into the prior breach, it had received data files from law enforcement "that a third party claimed was Yahoo user data", which it now confirmed to be true.- AFP
