最近ワードプレスにログインをしようとするアクセスが連続しています。最初は特定のアドレスだけでした。そこで、下記のように記入して防御しました。
<Directory /var/www/html/>
Options FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
allow from all
Deny from 99.192.223.130
Deny from 92.222.3.67
</Directory>
今日、ワードプレスのログを見てみたら、色々なIPアドレスからのアクセスが来ていました。そこで、今回はログインファイルへのアクセスを特定の範囲に限定しました。
<Files ~ “wp-login.php*$”>
Order deny,allow
deny from all
allow from .oita-u.ac.jp
</Files>
（普通は公開するものではないんでしょうが）うまく効いているように見えます。ひっかかったことは、deny と allow の間にはコンマのみ挿入することという決まりがありました。スペースを入れると apache がエラーを起こします。
下記に，ログインを試みてきたIPアドレスをあげます。複数回試みた場合はその回数だけ上げています。これで全部ではありません。本当にたくさんのパソコンが乗っ取られています。あるいはIPを偽装しているのでしょうか？ただそのことに意味があるのかどうか分かりませんが。
