【事例】有名ではないサイトへの攻撃

こんにちは。経理の小高です。

先日のブログ「Webサイトへの攻撃」をアップしたところ、「有名なサイトだからじゃないの?」と社長から言われました。

そんなことは全然なくて、攻撃者はプログラムで手あたり次第に攻撃してきます。ホームページは必ずどこかのホームページからリンクが張られていますので、それをたどってやってくるという仕組みになっています。

ちょうどうちの会社に攻撃に来たので、ログにアップしてみます。IPアドレスも公開してしまいますが、中国からのようです。

わたしどもの会社はWordPressというCMSでホームページを制作するのが得意です。SEO的にもベストなチョイスと言われています。

WordPressのサイトのバックエンドには、一般的にLAMP(Linux、Apache、MySQL、PHP)というサーバーソフトウェアの組み合わせになっています。

よく問題になる「改ざん」とか「SQLインジェクション」とかはこれらのサーバーソフトウェアや、Wordpressの本体もしくはプラグインの脆弱性を狙います。

この攻撃者はLAMP構成のサーバーに一般的にインストールされている「phpmyadmin(ピーエイチピー・マイ・アドミン)」という管理ツールにログインできないか、URLをいろいろと変えて(それっぽい名前にして)アクセスしています。

以下のログを見ていただくと、全部、はねつけていますので、うちのホームページがこの攻撃者になにかされた可能性は低いです。

とはいえ、うちのホームページというのは相当にマイナーな存在のはずですが、こういうことが始終起こっているのが現実です。
