There has been no information about leaks of such a massive database of user IDs as yet and according to Yahoo, the information that was stolen didn’t have passwords or any other information that would allow unauthorized users to carry out user identity verification.

Yahoo hasn’t ruled out the possibility of a leak though considering the volume of traffic it noticed flowing from its servers to external entities.

Following the alleged breach, Yahoo has revealed that it has beefed up its security controls to avert any such future attempts. Yahoo is the top most search provider when it comes to Japan with over 50 per cent market share. Google holds 40 per cent market share in comparison.

Japan has already acknowledged that the country lags behind in cyber security plans specifically in the preventative aspects that would otherwise deter such attacks.
