Steam: 昨年のデータベースへの侵入について続報

News - Message from Gabe to Steam Community

Dear Steam Users and Steam Forum Users:

We continue our investigation of last year's intrusion with the help of outside security experts. In my last note about this, I described how intruders had accessed our Steam database but we found no evidence that the intruders took information from that database. That is still the case.

Recently we learned that it is probable that the intruders obtained a copy of a backup file with information about Steam transactions between 2004 and 2008. This backup file contained user names, email addresses, encrypted billing addresses and encrypted credit card information. It did not include Steam passwords.

We do not have any evidence that the encrypted credit card numbers or billing addresses have been compromised. However as I said in November it's a good idea to watch your credit card activity and statements. And of course keeping Steam Guard on is a good idea as well.

We are still investigating and working with law enforcement authorities. Some state laws require a more formal notice of this incident so some of you will get that notice, but we wanted to update everyone with this new information now.

Gabe

あまり状況が変わっていない気がする。「侵入者が 2004-2008 年の Steam transaction のバックアップのコピーを得たかもしれない」。このバックアップには、ユーザーネーム、メールアドレス、暗号化された住所とカード情報、が含まれているらしい。Steam のパスワードは含まれていない。

そして、侵入者がバックアップデータを取得した可能性があるが、暗号化された住所とクレジットカード番号が不正利用された証拠が(まだ)見つかっていないらしい。セキュリティーの専門家の助けを借りてもあまり進展が無いとなると、相当凄腕なクラッカーだったのだろうか。ただ調べて得られた全ての情報を公開してくれているわけでは無いだろう。
