We recently heard that a massive leak of Yahoo passwords has been floating on the interwebs for a few days. According to Ars Technica, the dump is from Yahoo Voice and the data was released in clear-text yes, clear text in 2012. It seems they were not storing the passwords securely.We got access to the dump and we can confirm that this leak is valid. We can not however confirm it is from Yahoo, the password analysis does not have many “Yahoo’s” in it we’ll explain later.That said, we recommend all Yahoo users to change their passwords ASAP! Specially on other services that you are reusing the same passwords. Better safe than sorry.
