たまたま当サイトのhttpdが重荷を背負っていることに気がつき，ログを見たら，逆引きできないけど，ドイツと解るIPアドレスから執拗にログインの試みが繰り返されていました．<\/p>\n\n\n\n
ログをさらに調べると，今月は2万5千回，先月は約2万回のログインアテンプトがありました．その前の1年間はだいたい月間1千〜1万2千回です．先月から急増していると言えます．<\/p>\n\n\n\n
たいていは悪意のない（けどリテラシーの低い）人のパソコンが乗っ取られて，ハッカーに操られてこのような不法行為を行うのだと思います．<\/p>\n\n\n\n
それにつけても，WordPressのサイトって狙われやすいのですね．何万も登録されている辞書でログインアテンプトを繰り返されてしまったら，リテラシーの低いサイトはハッキングされてしまうでしょうね．<\/p>\n\n\n\n
とりあえず，現在執拗にログインアテンプトを繰り返すIPアドレスをフィルタリングしました．まあ，また別の乗っ取ったパソコンから攻めてくるんでしょうけど．<\/p>\n","protected":false},"excerpt":{"rendered":"
