Oath (Y! 的新東家，Verizon 持股) 發表了新的通報，外洩數量直接上升到 3 billion 了：「Yahoo provides notice to additional users affected by previously disclosed 2013 data theft」。
Subsequent to Yahoo's acquisition by Verizon, and during integration, the company recently obtained new intelligence and now believes, following an investigation with the assistance of outside forensic experts, that all Yahoo user accounts were affected by the August 2013 theft.
在「Yahoo says all 3 billion user accounts were impacted by 2013 security breach」這邊的報導則是寫的比較清楚，把當時的使用者數字翻出來：
Yahoo today announced that the huge data breach in August 2013 affected every user on its service — that’s all three billion user accounts and up from the initial one billion figure Yahoo initially reported.
2013 這包用的是 MD5 hash，以現在的運算能力來看，可以當作沒有 hash...：
The stolen user account information may have included names, email addresses, telephone numbers, dates of birth, hashed passwords (using MD5) and, in some cases, encrypted or unencrypted security questions and answers.
已經是 "all" 了，接下來要更大包只能是其他主題了...
