Google hacking is a term that refers to the act of creating complex search engine
queries in order to filter through large amounts of search results for information
related to computer security. In its malicious format it can be used to detect
websites that are vulnerable to numerous exploits and vulnerabilities as well as
locate private, sensitive information about others, such as credit card numbers,
social security numbers, and passwords. This filtering is performed by using advanced
Google operators [1], [2]. While Google was the original tool of the Google hackers,
many of the tactics and operators can be used on other search engines, such as MSN Search
and Yahoo.
