Yahoo Inc warned on Wednesday that it had uncovered yet another massive cyber attack, saying data from more than 1 billion user accounts was compromised in August 2013, making it the largest breach in history, reported by Reuters.

In a statement, Yahoo’s Chief Information Security Officer Bob Lord said that “an unauthorized third party, in August 2013, stole data associated with more than one billion user accounts.”

“We are notifying potentially affected users and have taken steps to secure their accounts, including requiring users to change their passwords. We have also invalidated unencrypted security questions and answers so that they cannot be used to access an account. With respect to the cookie forging activity, we invalidated the forged cookies and hardened our systems to secure them against similar attacks. We continuously enhance our safeguards and systems that detect and prevent unauthorized access to user accounts,” reads the statement.

Yahoo used to be the dominant search tools but has failed to keep up with the likes of Google and Facebook.
