Yahoo has confirmed a “State-Sponsored “attack in which hackers have stolen information from 500 million user accounts. The statement given by the Yahoo’s Chief Security Officer suggests that information was stolen in late 2014 from company’s network.
The account information includes name, date of birth, hashed passwords and few encrypted or unencrypted security questions. Although, investigation suggests that the stolen information excludes unprotected passwords, payment card details and bank account information.
On further investigation it was also revealed that the attacker is not working in Yahoo’s network at present and Yahoo is working with law enforcement on the same. Yahoo has also mentioned that they have unencrypted security questions and answers so that it cannot be used to access user accounts.
The company had started notifying about the breach via emails and asked the users to change their passwords and also opt for an alternative option to verify the account. Also for people who are not affected by the same are suggested to use Yahoo Account Key which is a new authentication tool which adds to layer of security.
In spite of all the efforts this security breakdown will add to Yahoo’s existing piles of problems of loosing users/traffic and advertising revenue which is going to its rivals.This theft actually represents most accounts that are ever stolen from a single email provider.
