There are a lot of different tools that helps us while making security tests, security assessment or hacking ;). These tools are sometimes open source sometimes paid software. Google is one of the tool that is used for security tests. It may seem ridicules but it is correct. We will see how google can be used as information gathering tool.

intitle

To search websites title attribute intitle can be used. We will search websites those have poftut in their titles in this example. This will list URL of all web which containts poftut . This may list different domain as we can see in the example.

intitle:poftut

 

allintitle

allintitle is similar to the title but difference is all provided terms is looked in the title. We will search websites those have both the poftut and tutorial in their titles

allintitle:poftut tutorial

inurl

To search pages url for a specified keyword use inurl. We will search websites those have poftut in their URL.

inurl:poftut

 

allinurl

Similar to inurl but searches for all provided keywords.

filetype

Google caches page as well as the file that resides in pages. These files can be search according to their types with filetype. We will search the sources those have txt type which means text files. File type is a generic term which is different then extension.

filetype:txt

ext

ext is similar to filetype. Direct extension of the files can be used with ext . We will search websites those have png extension in this example. This will only list png entension not other image types.

ext:png

intext

intext can be called Google’s primary function. It searches in pages texts. We will search sites those have the word poftut in the content or web pages html.

intext:poftut

allintext

allintext is similar to the intext search but searches for all keywords in the page. This will specify multiple search terms for website content search. In this example we search both poftut and ansible in the same web page. We can call this as AND logic.

allintext:poftut ansible

site

Up to now we generally searched for the whole internet but to limit our search for a specific site use site and provide the domain name. This is one of the most used option. This will search ansible word in the domain named poftut.com

site:poftut.com

Search All Of Multiple Terms with AND Logic

Google Search also provides some useful logic operations. One of the is the most basic logic operation AND . This logic can be used to math multiple terms in a single search. In this example we will search file extension with file and text site . We will search png extension with poftut.com term.

file:png AND site:poftut.com

 

Search One Of Multiple Term

Another very useful logic is OR logic which simply means match one of the given terms. In this example we will use multile inurl to math terms pof and tut for one of them.

inurl:pof OR inurl:tut
