Mandient sets each account at roughly ~$200, so this is one of the most costly breaches ever.
Sources state, this breach became known in August when an infamous cybercriminal named “Peace” claimed on a website that he was selling credentials of 200 million Yahoo users from 2012 on the dark web for just over $1,800. The data allegedly included user names, easily decrypted passwords and personal information like birth dates and other email addresses.
So similar to the words of famous/infamous hacker Lauri Love (@LauriLoveX), If you’ve used a password anywhere online since 2012 and are still using it today, then it’s not a secret anymore. Someone has your password.
