Ada banyak tipe hack dari sebuah situs web. Hack dapat karena program yang tidak baik (malicious) seperti instalasi virus di web anda sehingga visitor kena virus tersebut, atau hack hanya mengubah kata-kata yang ada di halaman muka.

Sangat penting untuk mengetahui jika web anda di hack, bagaimana web tersebut di hack, dan bagaimana untuk mengembalikan ke kondisi sebelum di hack.

Apakah Web site kita di hack?

Beberapa hacking web terlihat dengan mudah, beberapa lainnya agak sulit untuk di lihat. Beberaa tanda web yang di hack antara lain adalah,

• Halaman muka web kita ter- "defaced." Jika kita mengunjungi web kita, kita akan mendapati halaman yang sangat berbeda dengan aslinya. Kadang kala, halaman tersebut di tambahkan "hacked by...." .
• Anda tidak dapat login ke halaman admin web. Jika anda kesulitan untuk login ke CMS administrator dan cPanal, maka kemungkinan situs anda di hack dan password di ubah.
• Anda memperoleh warning Google ketika mengunjungi web site anda. Google akan menscan semua situs web akan keberadaan aplikasi berbahaya (malicious coding). Jika Goohle menemukan file yang berbahaya, maka jika anda mengunjungi situs tersebut melalui Google search atau di FireFox/Chrome dia akan menampilkan halaman warning berwarna merah.
• Program antivirus di komputer anda memperingatkan saat anda masuk ke situs anda. Jika program antivirus anda memperingatkan akan adanya virus di situs web anda, kemungkinan memang ada sebuah virus atau trojan dari web anda yang berusaha untuk menginstalasi ke komputer anda.
• Sebuah halamanan yang tadinya bisa di load sekarang tiba-tiba tidak bisa. Hal ini tidak biasa, tapi jika seorang hacker memodifikasi database di situs web anda dan membuat tidak berfungsi normal, anda mungkin akan memperoleh berita misalnya "can not connect to database" atau berita yang mirip saat loading sebuah halaman.

Bagaimana Situs Web Kita di Hack?

The more common methods used to hack websites include:

   Hacked cPanel or FTP password
   Code injection - http://en.wikipedia.org/wiki/Code_injection
   Remote File Inclusion - http://en.wikipedia.org/wiki/Remote_File_Inclusion

If your password has been hacked, generally this will lead to your front page being "defaced" as the hackers will upload their own index page. If you use a software such as WordPress, ZenCart, or other programs, often time the hacks are done through an exploit in those programs. In many cases, if you use a CMS program the database will be hacked as well and will need to be restored.

How do I fix my website that is hacked?

It is difficult to give an exact method to resolve a hacking issue as there are many different types of website hacks, here are some general steps to take to correct your website:

   Restore backup of your website.  The easiest way is to restore your site from a version that was saved prior to the site being hacked.  If you have paid for the automated backup service, please contact our support team so that your website can be restored from the backup.  If you do have the automated backup service, then you will need to restore your own backup of your website through the cPanel.
   Remove the coding from the .htaccess file.  Many times if the site is hacked by code injection, there will be a "re-direct" placed in your .htaccess file in your public_html folder.  Open your .htaccess file and look for any lines of coding that look suspicious.  Delete the suspicious lines of coding, and then save your changes.

What should I do prevent my site from being hacked?

Depending on the cause of the hack, there are some steps you can take to help prevent hacks in the future:

   Change any passwords for your account.  This is always the recommended first step.  In case your passwords were compromised, change your cPanel password, any FTP account passwords, and if you use WordPress or a CMS change that password as well. 
   Update Programs running on your hosting account. If you use third party software to build your site, such as WordPress or Joomla, make sure you are using the most up to date version as security exploits may have been fixed by the developers.
   Update Programs running on your computer.  Some programs, such as Adobe's Flash, include vulnerabilities that allow hackers to access data on your computer. They can then sniff around and find data, such as FTP usernames and passwords that are saved in some programs. Be sure that you keep all of your software up to date as most developers often release security patches.
