Master Google Hacking: Essential Search Operators for Security Recon

Information gathering and social engineering are crucial components of cybersecurity. This article introduces common Google Hacking techniques that let attackers use search engines to discover valuable information.

site

Syntax: site Purpose: limit search to a specific domain.

Example: searching for the vulnerability ID CVE-2014-4114 on Microsoft’s official site returns only results from that domain, dramatically reducing noise.

filetype

Syntax: filetype Purpose: search for a specific file type.

To find PDF e‑books related to web security, use the filetype operator. The results will consist mainly of PDF documents, making it easy to locate technical manuals and research papers.

inurl

Syntax: inurl Purpose: find URLs containing specific strings.

Useful for locating potentially vulnerable pages, such as those with query parameters indicating SQL injection points:

inurl:.php?id= inurl:.jsp?id= inurl:.asp?id=

It can also reveal admin login pages:

inurl:login.php inurl:login.jsp inurl:login.asp

Combining inurl with site narrows the search to a particular domain, helping pinpoint attack vectors.

intitle

Syntax: intitle Purpose: search for pages whose HTML title contains specific keywords.

Many admin panels include words like "admin", "login", or "dashboard" in their titles. Using intitle helps locate such pages quickly.

intext

Syntax: intext Purpose: search the body text of pages for specific terms.

For example, to find forums built with Discuz, include intext:discuz in the query.

Google Hacking Database

The Exploit‑DB Google Hacking Database (GHDB) aggregates a large collection of useful search queries. It serves as a valuable reference for security researchers and penetration testers.
