Yahoo: Over 453,000 Credentials Leaked

1

Hackers publicly posted the login credentials of over 453,000 yahoo accounts obtained by an SQL injection in Yahoo Voice probably. A hacker group D33D had claimed the responsibility of the hacking, though thier Ukraine based website is untraceable for now as the registrar details are found to be invalid. So the risk level of accounts being hacked is high as the possibilities multiplies with the figures of the accounts being exposed.

Yahoo has no word on it for now, but it said that a statement is yet to be released regarding this password leak. I think its better to change your Yahoo account password now and I’d recommend to change the password of other accounts if you have used the same for those including your security questions.

Few days ago, LinkedIn and eHarmony were the victims of credentials theft. Yahoo joins the club along with them, with an alarm about privacy and security vulnerabilities of a top level company. Google is not an exception too, as the operation aurora which originated from china, attacked most of the companies including Google and exposed many security holes.

The security loopholes are still a serious challenge for the biggies too, as hackers are nourished by vivid resources and knowledge. Yahoo must come up with a better immune system for its services that encrypts the passwords for the least, as this case also showed up that the passwords are left unencrypted.

The following are some interesting passwords.
