Yahoo is now in a place where not a single tech company should ever be. They suffered from yet another data breach and I think it is the biggest one in history.
Yahoo announced today that the breach of more than one billion user accounts occurred in August 2013 and that they just alerted by law enforcement. Yahoo also said that they believe this one's different from the one in September, which caused over 500 million account breach. Okay.
For this one, seems like the data doesn't include payment information or plaintext passwords. But still, names, email addresses, telephone numbers, dates of birth, hashed passwords and some encrypted or unencrypted security questions and answers were stolen. Yahoo notified its users about the breach and said that they have taken steps to secure the affected accounts, including requiring users to change their passwords.
