  3. What is Google hacking? • It's not hacking into Google servers! • Google hacking is using different Google operators to effectively optimize search results. • It also involves using Google to identify vulnerabilities in websites. • Results are highly customizable.

  4. Basic operators • • For inclusion of something common (+) • Words that are commonly used, like 'the,' 'a,' and 'for,' are usually ignored (these are called stop words). • • Terms you want to exclude (-) • Anti-virus -software • Georgia -america -state • • Search for an exact term (“) • “enter your text here”

  5. Basic operators cont. • • ( * ) any word (wild card) • If you include * within a query, it tells Google to try to treat the star as a placeholder for any unknown term(s) and then find the best matches. • Estonia parliament voted on the * bill • • ( | ) boolean ‘OR’ • I'll let you guess this one on your own.

  6. Advanced operators • Advanced operators use a syntax such as the following: • operator:search_term • • There’s no space between the operator, the colon, and the search term!

  7. Advanced operators • Intitle: Google returns results with the word/phrase found within the title of the page Intitle:index.of • Inurl: Finds a specific term within the URL Inurl:view/index.shtml

  8. Advanced operators • Filetype: Searches for a specific filetype filetype:pdf filetype:txt The previous operators are the most commonly used ones.

  9. Mixing operators Improvise! • Inurl:securethiscompany.com intitle:index.of • "mysql dump" Inurl: filetype:sql intext:password • inurl:ftp "password" filetype:xls

  10. intitle:admin intitle:login • Search for phpMyAdmin installations that are configured to run the MySQL database with root privileges: intitle:phpMyAdmin “Welcome to phpMyAdmin ***” “running on * as root@*”

  11. Johnny I hack stuff • Most of this information was underground until Johnny Long put it into public hands and published the “google hacking database” • Last year he changed his website and started doing charity work.

  12. The old GHDB (last update 2006) • http://www.hackersforcharity.org/ghdb/ • The new and up-to-date GHDB http://www.exploit-db.com/google-dorks/
