What is the Google Hacking Database?
Originally created by Johnny Long of Hackers for Charity, The Google Hacking Database (GHDB) is an authoritative source for querying the ever-widening reach of the Google search engine. In the GHDB, you will find search terms for files containing usernames, vulnerable servers, and even files containing passwords.
GHDB : hosted and maintained by Offensive Security
When The Google Hacking Database was integrated in The Exploit Database, the various googledorks contained in the thousands of exploit entries were entered into the GHDB. The direct mapping allows penetration testers to more rapidly determine if a particular web application has a publicly available exploit.
