• Google Hacking involves using the Google search engine to identify
vulnerabilities in websites.

• Ok, so you use Google to find all of this stuff, but how do you?
• Google supports a multitude of operators and modifiers that add a ton of
power to google searching.

• Mmmmmm....operators and modifiers! I want them!

• cache:
• Syntax: cache:URL [highlight]
• The cache operator will search through google’s cache and return the
results based on those documents. You can alternatively tell cache to
highlight a word or phrase by adding it after the operator and URL.

• link:
• Syntax: link:URL
• Sites that have a hyperlink to the URL specified will be returned in the
search results.

• allintitle:
• Syntax: allintitle: oper1 [oper2] [oper3] [etc..]

after the modifier within the title. NOTE: This modifier does not play well
with others.

the modifier within the title of the page.

• allinurl:
• Syntax: allinurl: oper1 [oper2] [oper3] [etc...]
• This modifier is similar to allintitle: in that it will use the rest of the query and
look for all the words or phrases in the URL that was specified. NOTE: Also
like allintitle:, this modifier doesn’t play well with others.
