How do the hackers use search engines
as a free hacking tool?
The
search engines are the most useful
and handy tool in the cyber world.
No matter what kind of information
you need, all you need is a browser
and an Internet connection and you
get everything that you are looking
for. But most of us forget that things
that are normally created to do good
to people can also be misused by people
whose only hobby or profession is
to get their hands on what they are
not allowed to. You would be surprised
to know that the only thing that turns
search engines like Google into an
easy but deadly weapon is the laziness
or less knowledge of people who has
got their stuff online. Unfortunately
a big majority of those people are
the System Administrators of the companies,
who fail to protect the important
confidential information that belongs
to their employer. I am not writing
this article to teach somebody how
to get somebody’s confidential
info or download illegal stuff. I
should not be held responsible for
any kind of misuse of the information
contained in this article.
What kind of
data can one actually search and download?
Nearly everything that can be downloaded
or accessed over Internet through
other means, can be downloaded or
accessed more easily and safely with
the help of search engines. This can
be the confidential electronic data
of your company such as xls, doc,
pdf, jpg etc files or this can be
illegal music or videos etc, and this
is not all; this can be the lists
of your passwords etc too which can
open access to your mail accounts,
bank accounts or other databases etc.
How does it
happen?
The answer is more then just simple.
Let’s take the the mother of
search engines "The Google"
as an example. The search engines
give you the facility to search specific
data types and that is the option
that is normally being misused. Imagine
yourself as a cyber thief who wants
to get certain information. Then think
what format could be the files that
would probably contain the information
you need. Ok how about getting some
password files? Oh Yes! They can most
probably be either .txt files or .xls
files which can be opened with Notepad
or Microsoft Excel program. You would
then use the Index of and filetype
strings to search the possible name
of the file along with the data type.
To do that you would simply go to
www.google.com and search for the
following phrase:
Index of /passwords filetype:txt
Or
Index of /passwords filetype:xls
The first query will return all the
results where the file types would
be .txt and the second one will show
you all files that are .xls type with
the passwords as the part of the names.
Everything that a thief needs is now
on the screen. Isn’t it scary?
Such an easy access to such a sensitive
data! Or consider getting a collection
of .mp3 songs free to download. The
cyber thief only needs the name of
the song and he will get it even in
multiple formats. Suppose he wants
to download the song "Push The
Button" in mp3 format. He just
goes to Google and searches for:
Intitle:index.of "push the button"
mp3
Wow, a whole list of web URLs where
this song is freely available to download
and not just this, the person who
whose URL provides the access to songs
has got his whole music albums uploaded
there. Normally those are URLs of
web spaces where some people or companies
upload their data and music etc but
forget that their site is listed in
search engines and without password
protection the folders and data can
be exposed to outside world. Now the
cyber thief is just a little bit scared
if he is accessing a big company’s
data, because the web site logs the
information such as IP addresses and
other details of their visitors. In
that case an expert thief uses a second
method for his safety "Anonymous
Proxy Servers". That means that
he involves a third party to reflect
the data to him. The anonymous proxy
servers masks the IP address and host
information of the visitor so that
means that if you are using a proxy
server and access my site; I would
not be able to see the real information
that can be used to identify you.
Anyway, the topic of proxy servers
can be discussed in the next article
as right now we can not go much in
detail.
