You can find all backdoor scripts using this little scanner. Just upload this script and open it..After hacking your site a hacker must leave any backdoor script on your server for getting future access so must find and remove that script.
A backdoor in an Operating System or a complex application is a method of bypassing normal authentication and gain access. During the development of an Operating System or application, programmers add back doors for different purposes. The backdoors are removed when the product is
ready for shipping or production. When a backdoor is detected, which is
not removed, the vendor releases a maintenance upgrade or patch to
close the back door.
Another type of
back door can be an installed program or could be a modification to an
existing program. The installed program may allow a user log on to the
computer without a password with administrative privileges. Many
programs ara available on internet to create back door attacks on systems. One of the more popular tools is Back Orifice which is also available for free download on internet.
