Google dorks, also known as Google hacking, involves using specific search operators and techniques on Google to find sensitive information on websites. Some key points made in the document include: - Google dorking uses operators like "site:", "filetype:", "intitle:", and "inurl:" to refine search results and maximize search value. This can be used to uncover private information, configurations, backups, and vulnerabilities. - Information found through Google hacking may remain exposed in Google's cache for months after being removed from websites. - Google indexes everything publicly available on the internet, making it a powerful tool for passive information gathering, which is an important first step for hackers. - The document encourages

- 2. Quick Survey
- 3. 2 Quick Survey • How many people have heard of Google Dorks before this Meet up ? • How many people have tried Google Dorks? • How many people are using Google Dorks for hacking purpose ?
- 4. Google Dorks • “Using public sources openly and without resorting to illegal means, it is possible to gather at least 80 percent of all information required about the enemy” - Al Qaeda training manual
- 5. What is Google Dorks and Google Hacking ?
- 6. 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. All Web site content is exposed to Google • Sensitive content might be available for months before the compromise is discovered • Even after sensitive pages are removed, they will be stored in Google Cache
- 7. Google Hacking • Google hacking is a term that refers to the art of creating complex search engine queries in order to filter through large amounts of search results for information related to computer security.
- 8. How it Works ? • Google Search indexes everything that is made public including “virtual notebooks” and the information stored within that notebook in their search results. • Google is one of the most powerful databases in the world
- 9. Information disclosure with Google • Private information • Remote Admin Interface • Configuration management • Error messages • Backup files • Public vulnerabilities • Technology Profile

- 12. Google Operators “Operators are used to refine the results and to maximize the search value. They are your tools as well as hackers’ weapons”
- 13. Google Operators • Basic Operators +, -, ~ , ., *, “”, |, OR • Advanced Operators allintext:, allintitle:, allinurl:, bphonebook:, cache:, define:, filetype:, info:, intext:, intitle:, inurl:, link:, phonebook:, related:, rphonebook:, site:, numrange:, daterange
- 14. Basic Operators • (+) force inclusion of something common – Google ignores common words (where, how, digit, single letters) by default: – Example: StarStarWars Episode +I • (-) exclude a search term – Example: apple –red • (“) use quotes around a search term to search exact phrases: – Example: “Robert Masse” – Robert masse without “” has the 309,000 results, but “robert masse” only has 927 results. Reduce the 99% irrelevant results • (~) search synonym: – Example: ~food – Return the results about food as well as recipe, nutrition and cooking information • ( . ) a single-character wildcard: – Example: m.trix – Return the results of M@trix, matrix, metrix……. • ( * ) any word wildcard
- 15. Advance Operators “Site” • Advance Operator : “Site” – Find Web pages only on the specified domain. If we search a specific site, usually we get the Web structure of the domain – Examples: • site:com • site:osscube.ca • site:www.osscube.ca
- 16. Advance Operators “Filetype” • Advanced Operators: “Filetype:” – Filetype: extension_type – Find documents with specified extensions – Example • filetype:pdf • filetype:xls • Site:osscube.com filetype:pdf • Site:osscube.com filetype:txt • Budget filetype: xls
- 17. Advance Operators “Intitle” • Advanced Operators “Intitle:” – Intitle: search_term – Find search term within the title of a Webpage – Allintitle: search_term1 search_term2 search_term3 – Find multiple search terms in the Web pages with the title that includes all these words – These operators are specifically useful to find the directory lists – Example: • Find directory list: • Intitle: Index.of “parent directory”
- 18. Advance Operators “Inurl” • Advanced Operators “Inurl:” – Inurl: search_term – Find search term in a Web address – Allinurl: search_term1 search_term2 search_term3 – Find multiple search terms in a Web address – Examples: • Inurl: cgi-bin • Allinurl: cgi-bin password
- 19. Advance Operators “Intext” • Advanced Operators “Intext;” – Intext: search_term – Find search term in the text body of a document. – Allintext: search_term1 search_term2 search_term3 – Find multiple search terms in the text body of a document. – Examples: • Intext: Administrator login • Allintext: Administrator login
- 20. Advance Operators “Cache” • Advanced Operators: “Cache:” – Cache: URL – Find the old version of Website in Google cache – Sometimes, even the site has already been updated, the old information might be found in cache – Examples: • Cache: www.osscube.com
- 21. Advance Operators “<number1>..<number2>” • Advanced Operators – <number1>..<number2> – Conduct a number range search by specifying two numbers, separated by two periods, with no spaces. Be sure to specify a unit of measure or some other indicator of what the number range represents – Examples: • Computer $500..1000 • DVD player $250..350
- 22. Advance Operators “Link” • Advanced Operators “Link:” – Link: URL • Find the Web pages having a link to the specified URL – Related: URL • Find the Web pages that are “similar” to the specified Web page – info: URL • Present some information that Google has about that Web page – Define: search_term • Provide a definition of the words gathered from various online sources – Examples: • Link: osscube.com • Related: osscube.com • Info: osscube.com • Define: Network security

- 24. Google “Friend or Enemy” • Google is everyone’s best friend (yours or hackers) • Information gathering and vulnerability identification are the tasks in the first phase of a typical hacking scenario • Passitive, stealth and huge data collection • Google can do more than search • Have you used Google to audit your organization today?
