はじめに
本記事は論理的なハッカーとして、インターネット上のパブリックリソースから組織の情報を収集する方法について記載しています。
本記事で紹介しているツールを活用することで、効率的なOSINTが実現できます。
OSINTについては、以前書いたIMINT/GEOINTをご参照ください。
Harvester
Harvesterは、パブリックリソースから電子メール、サブドメイン、ホストなどの情報を収集することができます。
Kali Linuxでは最初からインストールされています。
どのような情報収集しているかについては、GitHubで公開されいてる以下リポジトリのREADMEより確認できます。
基本的な使い方は、-dのオプションでドメインを指定、-bにソースを指定して実行します。
以下の例では、-lで検索結果を制限しています。
$ theHarvester -d <domain> -l 200 -b yahoo
- 出力例

Sherlock
Sherlockは、さまざまなソーシャルネットワークから対象となる人物に関する情報を収集することができます。
Kali Linuxでは最初からインストールされていないため、別途インストールが必要です。
SherlockもGitHubに公開されいてるため、直接ダウンロードして使用することもできます。
基本的な使い方は、調査したいユーザー名を指定して実行します。
コマンドを実行後、ヒットしたソーシャルネットワークのURLを出力します。
$ python3 sherlock <USERNAMES>

その他
OSINTに関連するサービスは他にもありますが、海外で開発されています。
名前の出てくるサービスとして、SpokeoやRocketReachがありますが、基本的に有料サービスとなっています。
RocketReachについては、一部無料で利用することができます。
無料で使えるWebサービスについては、WhatsMyNameが便利だと思います。
使い勝手としては、SherlockのようにヒットしたソーシャルネットワークのURLを列挙できます。
おわりに
Harvesterは組織に関するターゲットドメインの情報、Sherlockについては個人の情報など用途に応じて使い分けるのが効率的だと思います。
