The Google Search Engine finds answer to our questions, which is helpful in our daily lives. You can search for your school assignments, reports, presentations and more. Before I start the tutorial on using use Google Dorks in Penetration Testing and Ethical Hacking, I'm going to share a definition of Google Dork queries that I saw on techtarget.com:

A Google Dork query, sometimes just referred to as a dork, is a search string that uses advanced search operators to find information that is not readily available on a website.

In other words, we can use Google Dorks to find vulnerabilities, hidden information and access pages on certain websites. Because Google has a searching algorithm and indexes most websites, it can be useful to a hacker to find vulnerabilities on the target.The basic syntax for advanced operators in Google is:


For example, this operator_name:keyword syntax can be typed as 'filetype:xls intext:username' in the standard search box, which results in a list of Excel files which we contain the term 'Username'.

Simple Google Dorks Syntax
site - will return website on following domain
allintitle and intitle - contains title specified phrase on the page
inurl - restricts the results contained in the URLS of the specified phrase
filetype - search for specified filetype formatsSee the images below:

Google Dorks can also be used for network mapping; we're able to find the subdomain of the target site using Simple Dorks.Information gathering and network mapping is useful in Ethical Hacking. See the image below:

Dorks:site:wipro.com -site:www.wipro.com -site:careers.wipro.com


Try wipro.com to scan and we find some of the subdomains using the master website. We see other login pages and other system administrators/webmasters are using the subdomains for login pages. Based on the results, it's not fully secured. That's why the site mapping in Google Dorks is good. How about a port scanning? Available ports for intrusion and open ports? Can Google Dorks find it? The answer is yes. See the image below:

Dorks:inurl:8443 -intext:8443


We use port 8443 and it's open; we find some websites enable port 8443. The queries above search websites using port 8443.

In this article, we presented a few uses of Google Dorks for testing our own website. We found out if it was searchable on Google and leaking confidential information. Thanks and Greetings from a Philippine Security Researcher and Project-AG
