Introduction to Google Dorking
An average internet user might feel that he/she can use the google search very but that’s not entirely true we have the advanced Google Search Users and they are the ones that know how to manipulate Google Search Queries (Google Dorking).
Some call this a hack well because you can actually lay your hands on Classified information if you can dork.
consider a Google user who typed “International Scholarships in Europe” sounds like a normal well structured search right? well check again..
Another user instead types “intitle: International Scholarships Location:Europe” they get different results, what makes these users different? one is an advanced user while the other is a normal user.
Attackers can manipulate this technique to exploit your data on the internet, your credit cards, debit cards, phone numbers, emails, Your footage on IP cameras and so on.
Arithmetic Operators / Google Calc :
Google can also be used as a calculator, here are the few calculator operators that you can
use to perform arithmetic operations in Google.
+ , – , * , / , % of , ^
Goto http://www.google.com and in the input box, type in the calculation that you want to perform,
something like 8-5, Then you can get the appropriate result. Likewise you can use the rest of
the Calculator operators.
+ and – is not only meant for performing arithmetic operations, but you can use them to narrow down your search. Search for hacking + ebooks this will search for both hacking and ebooks, but gives more priority for ebooks rather that hacking.
Search for hacking – cracking so that you can restrict cracking related sites and info while searching for hacking.
This operator searches for the exact phrase within speech marks only. This is ideal when the phrase you are using to search is ambiguous and could be easily confused with something else, or when you’re not quite getting relevant enough results back. For example:
This will search for only the finer tinned variety of the bread based snack, at the exclusion of all others.
This self explanatory operator searches for a given search term OR an equivalent term. For instance, if you have an unhealthy fascination with the famous ‘Sheens’ you could search for:
“Martin Sheen” OR “Charlie Sheen”
Then immediately seek psychiatric help.
– (and +)
The – operator removes pages that mention a given term from search results. For example, if you were searching for information about Manchester, but didn’t want your results to be polluted by information about the city’s red clothed football team, you could search for the following:
This would return results for “Manchester”, while removing any that feature the word “united”. Using + forces Google to return common words that might ordinarily be discarded, for example:
Peanut Butter +and Jam
Adding a tilde to a search word tells Google that you want it to bring back synonyms for the term as well. For example, entering “~set” will bring back results that include words like “configure”, “collection” and “change” which are all synonyms of “set”. Fun fact: “set” has the most definitions of any word in the dictionary.
This searches only within a given domain – delectable when you want to only search within the confines of a particular site. For instance, if I were looking for members of my close peer group that I regularly go drinking with, on Twitter, I would search for the following (in turn, not all at the same time):
site:twitter.com Paul Daniels
site:twitter.com Geoffrey Archer
site:twitter.com Alan Hansen
site:twitter.com Nicholas Lyndhurst
Use this operator to find links to a domain. Bonus note: Google only provides a sample of backlinks, meaning that this operator isn’t very useful for uncovering the complete selection of links to a site, but it is good for quickly identifying a sample of sites that link to a specific domain. For example:
For a more complete selection of backlinks, use the Yahoo! operator –linkdomain: – which we will cover later.
allintitle: (and also intitle:)
Searches only for sites with the given word(s) in the page title. Intitle: does the same thing but for single words and can be used with more flexibility. For instance, if I searched:
The results would show pages with just “hammer” in the page title, and with “nails” elsewhere. Note: in blog search this same function is performed by inblogtitle: and inposttitle:
allintext: (and also intext:)
This operator searches only for sites where the given word(s) are in the text of the page.
allinanchor: (and also inanchor:)
This shows sites which have the keyterms in links pointing to them, in order of the most links. For instance, if I searched for allinanchor:helicopters, Google would show me the top sites which are linked to, where the anchor text for the link is “helicopters”.
allinurl (and also inurl:)
Similar to the last few, but fetches results where the key words are in the URL. This is useful if you’ve forgotten the exact URL of a website, but can still remember bits of it. Note: in blog search this same function is blogurl:, making it handy for searching for topics on specific platforms. For example:
Would find WordPress blogs that are – paradoxically – talking about Blogger.
Will reveal a list of webcams – useful for voyeurs.
allinpostauthor: (and also inpostauthor:)
Exclusive to blog search, this one picks out blog posts that are written by specific individuals. For instance, if you wanted sound advice on how to use Online PR and Social Media to improve your company’s ROI, you could try:
Putting an asterisk in a search tells Google ‘I don’t know what goes here’. Basically, it’s really good for finding half remembered song lyrics or names of things. If you put the asterisk in a search like:
I’ve got a brand new pair of *
Google will fill in the blank and tell you that you’ve got a brand new pair of Belgians, hopefully. Though it’ll more than likely be rollerskates.
+ (immediately before query)
Google is now craftily providing a wide range of synonym results in response to relevant search queries. For example, if I search for “California”, Google knows that this is the same as “CA” and will also return results for the latter but – and it’s a huge but – if I suffer from abbrphobia (fear of abbreviations), then just looking at the word “CA” will hurl me into a massive world of terror. I want to avoid these words like my life depends on it. So, I use:
Google: providing safety and reassurance for abbrphobics.
Simple: it returns searches for sites that are related to a given domain. This one is interesting for testing Google’s semantic perception of a given domain, for example:
Use two full stops to search in a range of numbers, for example:
I own 1..100 cats
Will bring back results that encompass searches on “I own 1 cat” to “I own 100 cats”. Totally useless.
Using this operator will tell Google to bring back information about a certain domain. It reveals:
- Google’s cache of the site
- Pages that are similar to the one you searched for
- Pages that link to the domain you searched for
- Other pages on the same domain
- Pages that contain the domain text on their page
This operator brings back results from pages in a given place. Even better, it can be used to search for specific types of places within that location, for example:
Will mostly return pages for pubs that are in Brighton. It’s clever.
Google can do anything. If you search:
It will bring back six definitions from different websites, from Wiktionary to encyclopedia.com.
This query will search within a given date and time range, but is a bit unusable because dates must be entered in the tricky Julian format. For example, the string:
This is one that only works in Google News search. If we look for:
Gordon Brown source:the_guardian
Google will show all the mentions of Gordon Brown in articles where The Guardian is identified as the news source.
This is another news operator that allows you to search for articles by location:
This lets you search for a certain filetype. For instance:
Will bring back only MP3 results. Useless note: you can also use the extension “ext:” to do exactly the same thing.
If you search:
movie:Iron Man 2
And then enter a location, Google will tell you where you can see the film and at what time. This operator can also be used in conjunction with the aforementioned “loc:”
This seems to only work in the US, but if you search:
You’ll be given a worrying list of phone numbers for people called John Smith.
This is a great and simple one:
Will bring back results both for Brighton pages on weather websites, as well as a little weather widget at the top of the results page.
I use this query to track the stock price of my investment portfolio – AND NOW YOU CAN TOO. Just use the operator followed by the company ticker symbol that you wish to receive information on, for example:
Will show stock information for Bank of America.
Shows Google’s most recent cache of a webpage.
Adding the word map after a locational search forces Google to produce map-based results.
Google can be used as a calculator. As part of this functionality, “In” is a superb function that can be used (among many other Google calculation operators) to work out the number of units of something in something else. For example:
mph in speed of light
