Web Shell Detector - PHP Script That Helps You Find And Identify PHP / CGI (Perl) / ASP / ASPX Shells

Web Shell Detector is a php script that helps you find and identify php/cgi(perl)/asp/aspx shells. Web Shell Detector has a “web shells” signature database that helps to identify “web shell” up to 99%. By using the latest javascript and css technologies, web shell detector has a light weight and friendly interface.

1. Upload shelldetect.php and shelldetect.db to your root directory
   
2. Open shelldetect.php file in your browser
   Example: http://www.website.com/shelldetect.php
   
3. Use default username & password
   Username: admin Password: protect
   
4. Inspect all strange files, if some of files look suspicious, send them to http://www.shelldetector.com team. After submitting your file, it will be inspected and if there are any threats, it will be inserted into a “web shell detector” web shells signature database.
   
5. If any web shells found and identified use your ftp/ssh client to remove it from your web server (IMPORTANT: please be careful because some of shells may be integrated into system files!).
