GScrape is a small perl script that uses Google's Ajax API (Google::Search) to find vulnerable websites.

Special thanks to Trep for his contributions to this article.

Introduction

Main article: Web exploitation tools

The purpose of this script is to demonstrate that one can easily create simple tools to do tedious tasks. This script requires the Google::Search perl module.

  • You can install Google::Search using CPAN:
Terminal

localhost:~ $ cpan -i Google::Search

Example

GScrape is a simple tool, it will look for a file specified by the user containing a list of search terms, query google with those search terms and retrieve an array of websites,

which are then tested for Local File Inclusion and SQL injection vulnerabilities, if any are found they are logged to the output file specified by the user.

 perl gscrape.pl -f dork.lst -o gscrape.log
RPU0j.png GScrape will not return any results unless your input file actually contains a list of search terms.

Search Terms

These are just some examples of general search terms, they are not guaranteed to find any vulnerabilities.. but they probably will, with that said you are responsible for what you do with what you find using this tool.

c3el4.png Please note that your search terms in the file DO NOT require "inurl:", GScrape adds it for you if it isn't there.
