Google Hacking Database (GHDB)

Using Google, an SQL injection on a random website can be performed within 0.2 Google seconds. Specially crafted words given as input to Google are named as dorks, or google dorks. These dorks can be used to reveal vulnerable servers on the Internet, to gather sensitive data, vulnerable files that are uploaded, sub-domains, and so on. Effective usage of Google Hacking can make the pentest process considerably easier.

Understanding Google Dorks Operators

Lets take a look at the special google search operators that are used to construct those high powered google hack search terms.

intitle – Specifying intitle, will tell google to show only those pages that have the term in their html title. For example intitle:”login page” will show those pages which have the term “login page” in the title text.

allintitle – Similar to intitle, but looks for all the specified terms in the title.

inurl – Searches for the specified term in the url. – For example inurl:”login.php” or inurl:login.jsp intitle:login.

allinurl – Same as inurl, but searches for all terms in the url.

filetype – Searches for specific file types. filetype:pdf will looks for pdf files in websites. Similarly filetype:txt looks for files with extension .txt – For example “sensitive but unclassified” filetype:pdf

ext – Similar to filetype. ext:pdf finds pdf extension files.

intext – Searches the content of the page. Somewhat like a plain google search. For example intext:”index of /” or Host=*.* intext:enc_UserPassword=* ext:pcf

allintext – Similar to intext, but searches for all terms to be present in the text.

site – Limits the search to a specific site only. – For example

If a hacker wishes to search by a field other than the URL, the following can be effectively substituted:

  • intitle:
  • inurl:
  • intext:
  • define:
  • site:
  • phonebook:
  • maps:
  • book:
  • froogle:
  • info:
  • movie:
  • weather:
  • related:
  • link:

These options will help a hacker uncover a lot of information about a site that isn’t readily apparent without a Google Dork. These options also offer ways to scan the web to located hard to find content.


Use this only for research purposes and ethical hacking, do not break any laws by exploiting weaknesses of companies!
