Have you ever have Yahoo? You may want to change some passwords.

Yahoo showed that violations of the 2013 leak of more than 1 billion accounts. It is separate from the offense very similar to Yahoo's 500 million accounts that were announced in September. At that time we had a guide to ensure that users of Yahoo had to do with their account. Because this information is relevant once again, we have brought back and updated this guide to reflect this latest offense.

Yahoo's director of information security, Bob Lord, said in his blog on Wednesday that the account data is received, "may", including name, email address, telephone number and date of birth. God also says that the password information, but not passwords in plain text, can be stolen, as well as some answers to security issues.
