Yahoo! 的資料外洩數量超過之前公佈的十億筆,上升到三十億筆

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」。

也就是當時所有的使用者都受到影響:

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...

Amazon 推出 AWS CloudTrail,可以稽核 API 使用量...

因為最近幾天是 re:Invent,所以 AWS 在這個期間會丟出很多新玩意。

這次推出的是 AWS CloudTrail,會將 API call 記錄起來存到 Amazon S3 或是透過 Amazon SNS 發出,於是你就可以利用這些資料分析出各種想要撈出的資訊:「AWS CloudTrail - Capture AWS API Activity」。

目前只支援北美的 US East (Northern Virginia) 以及 US West (Oregon),也就是 us-east-1 與 us-west-1。
