'One billion' affected by Yahoo hack | 'One billion' affected by Yahoo hack |

Yahoo has said more than one billion user accounts may have been affected in a hacking attack dating back to 2013. | Yahoo has said more than one billion user accounts may have been affected in a hacking attack dating back to 2013. |
The internet giant said it appears separate from a breach disclosed in September, when Yahoo revealed some 500 million accounts were accessed in 2014. | |
Yahoo said names, phone numbers, passwords and email addresses were stolen, but not bank and payment data. | |
The company, which is being taken over by Verizon, said it is working closely with the police and authorities. | |
When Yahoo disclosed in September the 2014 data breach, the company said information had been "stolen by what we believe is a state-sponsored actor". Yahoo did not say which country it held responsible. | |
That breach included swathes of personal information, including names and emails, as well as "unencrypted security questions and answers". | |
The hack took place in 2014, and Yahoo has come under pressure to disclose why it took so long for the breach to be made public. | |
The new breach raises fresh questions about Verizon's $4.8n proposed acquisition of Yahoo, and whether the US mobile carrier will try to modify or abandon its bid. | |
If the hacks cause a user backlash against Yahoo, the company's services would not be as valuable to Verizon. | |
In a statement, Verizon said that it would evaluate the situation as Yahoo investigates and would review the "new development before reaching any final conclusions". | |
Yahoo said on Wednesday that users should change their passwords and security questions. |
