Deface

What is deface ?? When  you deface a website it mean you replace the index.php of the website with your own index.php ! How you can do this ? It is hard .. First of all you will need to find vulnerabilities and then upload a file named shell that will help you to change everything you want in the script !

Also to find vunerabilities you will need a powerfull tool named Acunetix .

Acunetix Web Vulnerability Scanner first identifies web servers from a particular IP or IP range. After that, it crawls the whole site, gathering information about every file it finds, and displaying the entire website structure.
