Security firm pours cold water on Yahoo's state-sponsored hack claim
On 22 September 2016, Yahoo's CISO Bob Lord confirmed to the world that in 2014 a "state-sponsored actor" had made off with the account information of at least 500 million Yahoo users.
Whoever perpetrated the hack not only stole those affected users' names and email addresses but also nabbed other important bits of personal information, including their dates of birth, phone numbers, (thankfully bcrypt-hashed) passwords, and unencrypted security answers.
