Beberapa hari yang lalu saya perhatikan tampilan web salah satu client ada iframe dan sisipan javascript yang sepertinya disisipi oleh orang luar.

Saya menemukan baris kode2 aneh seperti berikut.

Code:

Yang pasti baris2 tersebut jauh dari default .htacces dari script yang digunakan oleh web yang bersangkutan.
Nah kira2 ada unsur apa dibalik file .htacces ini??

Wah wah wah... saya cek lebih lanjut folder dan file tujuan dari htaccess diatas ternyata didalamnya ada banyak log sql injector dll... ini ada apa ya kira2, client yang kebobolan atau jangan2 dia sendiri yang sengaja pasang script2 aneh tersebut...

Banned!
setahu saya itu securty httacces bukan kebobolan :D

misal bagian

RewriteCond %{QUERY_STRING} ^(.*)(%3D|=|%3A|%09)https(%3A|:)(/|%2F){2}(.*)$ [NC,OR]
RewriteCond %{QUERY_STRING} ^(.*)(%3D|=|%3A|%09)https%3a(%3A|:)(/|%2F){2}(.*)$ [NC,OR]
RewriteCond %{QUERY_STRING} ^(.*)(%3D|=|%3A|%09)http(%3A|:)(/|%2F){2}(.*)$ [NC]

itu fungsi diatas buat nutup website biar gak di sql injection jika ada yang akses maka akan di lempar ke ke RewriteRule (.*) /huwad/blocker/blocker1.php [L] atau ke file blocker1.php

Click to expand...

Yang pastinya gak ada masalah dengan kode .htaccess itu, kodenya itu sebagai pengaman webnya dia :D
Kalau ada yang mo coba coba injeksi database, klo mo coba akses file penting yang ada dalam hosting semuanya ke tendang ke file yang ada di subdirektori /huwad/blocker/ :D
Kalau mau tau lebih jelas kode .htaccess diatas itu fungsinya untuk apa mampir ajah kesini

Terimakasih untuk semua masukannya. Setelah kemarin saya perhatikan lebih lanjut sepertinya memang benar apa yang dikatakan mas bantuemak dan mas bolanaga, ternyata file huwad yang dimaksud sebenarnya justru untuk membentengi web yang bersangkutan.
Melihat log yang tersimpan disana ngeri juga... ternyata banyak bener yang mau nyoba iseng sama web klien tersebut...

Kayaknya lumayan bagus file ini :)
