Google Tricks and hacks by d00m

Google.com is undoubtedly the most popular search engine in the world. It offers multiple search features like the ability to search images and news groups.However it's true power lies in it's powerful commands that can be used and misused.I am writing this article on the basis of my experience using google and trying out ideas when i am bored.Now enough of lecturing...let's get

down to business.)

--- Searching URLs :

The "allinurl" command is used to search for a particular string present in

the URL.Goto google.com and type this in the search box:

allinurl:wwwboard/passwd.txt

Wow! 139 results and allmost every result displays a file containing a string

in the form of ---> username:password (password is encrypted using DES crypto and can be cracked using john the ripper) "WWWBOARD" is a CGI message board which saves it's password by default in a filename called "passwd.txt".This is a very outdated message board script but many new types of CGI/PHP/ASP messages boards and scripts save their passwords

in a text file (some are not encrypted i.e. in plain text !! and the rest can most of the time be cracked with john the ripper)

allinurl:passwd.txt site:virtualave.net

This time too you will get some results which leads to the file containing the

passwords.

This command searched for a file called passwd.txt present in the URL.However

using the "site:virtualave.net" part has limited the search to virutalave.net only! (virtualave.net is a web hosting provider)

Similarly you can also search partcular top level domains like

.net,.org,.np,.jp,.in,.gr etc :

allinurl:config.txt site:.jp

allinurl:admin.txt site:.edu

These and many other ideas can return interesting results in google.

--- Searching for Index browsing enabled directories :

Index browsing is a very simple but powerful way of gaining information and interesting things.First of all we need to understand that "index browsing" enabled directories are those directories on the internet that can be browsed just like ordinary directories. We will be using google to find such type of "interesting" directories.

Try these out this in google:

"Index of /admin"

"Index of /secret"

"Index of /cgi-bin" site:.edu

Be more creative and think of more interesting ways to exploit index browsing,

-- Searching for partcular file types:

You can specify the extension of the filename you want to search using "filetype" command. Examples to try in google:

filetype:.doc site:.mil classified

-Yeah searching for classified millitary documents ;)

-- Examples of some real life hacks using google:

1) My personal hack

One day i was reading about an exploit for phpBB 2.0.0 I decided to check

if any sites were vulnerable, so i fired up google and searched for:

"Powered by phpBB 2.0.2"

I found out that there were a lot of site.But i got curious to see if any

Nepali sites were vulnerable too because I am a Nepali myself ;)

"Powered by phpBB 2.0.2" site:.np

I came up with a vulnerable Nepali site that used phpBB 2.0.2

2) Big brother hack

Phrack 60 has an article on Big Brother...(a program that will monitor

various computer equipment; things it can monitor are connectivity, cpu

utilization, disk usage, ftp status, http status, pop3 status, etc.)

You can search for sites using big brother by typing this search string in

google:

"green:Big Brother" (with the quotes)

For more info check out article titled "Watchin Big Brother" @ phrack.org

--Conclusion:

This document is only meant to give some basic ideas about exploiting

google.com. I was very much inspired by +Fravia and his site : http://searchlores.org which has lots of innovative ideas and tricks.
