Overview What You Will Learn Curriculum Instructor

Course Overview

Web Application Security Testing with Google Hacking is a powerful reconnaissance technique that leverages search engine queries to uncover hidden vulnerabilities in web applications. Often underestimated, Google Hacking—or “Google Dorking”—uses specially crafted search operators to identify misconfigurations, exposed files, sensitive data, and other security flaws indexed by search engines. Learning this technique is essential for ethical hackers and security professionals, as it helps uncover weaknesses that traditional vulnerability scanners might miss, and also informs defenders how to secure their web presence from public exposure.

This course begins with practical demonstrations of how to use Google Dorks to find directory listings, SQL syntax errors, and publicly exposed backup files that may inadvertently reveal sensitive application data. It progresses to identifying internal server errors, sensitive information in URLs, and web pages still using insecure HTTP. Learners are introduced to the Google Hacking Database (GHDB)—a rich repository of tested queries—and apply their knowledge through a real-world case study on Microsoft’s Yammer social network. The course concludes by discussing preventive strategies to stop sensitive data from being indexed by search engines, strengthening the overall web security posture.

By the end, learners will be skilled in identifying and preventing web exposure risks using Google Hacking techniques.
