How To Hack Into A Computer On LAN
NetBIOS
Hacking
-What
is it?-
NetBIOS
Hacking is the art of hacking into someone else’s computer through your
computer.
NetBIOS stands for “Network Basic Input Output System.” It is a way for
a
LAN or WAN to share folders, files, drives, and printers.
-How
can this be of use to me?-
Most
people don’t even know, but when they’re on a LAN or WAN they could possibly
have
their entire hard drive shared and not even know. So if we can find a way into
the
network, their computer is at our disposal.
-What
do I need?-
Windows
OS

-[Step
1, Finding the target.]-

So
first off we need to find a computer or the computer to hack into. So if your
plugged
in to the LAN, or connected to the WAN, you can begin. Open up Cain and
Abel.
This program has a built in sniffer feature. A sniffer looks for all IP
addresses
in
the local subnet. Once you have opened up the program click on the sniffer tab,
click the Start/Stop sniffer, and then click the blue cross 
Another
window will pop up, make sure “All host in my subnet” is selected, and then
click
ok.
It
should begin to scan.
Then
IP’s, computer names, and mac addresses will show up.
Now
remember the IP address of the computer you are going to be breaking into.
If
you can’t tel whether the IP address is
a computer, router, modem, etc, that’s ok.
During
the next step we will begin our trial and error.

2, Trial and Error]-
++++++++++++++++++++++++++++++++++++++++++++++++++
++++++++++++++++++++++++++++++++
++++++++++++++++++

Now,
we don’t know if we have our designated target, or if we have a computer or
printer,
or whatever else is on the LAN or WAN.
If
you did get the IP of the target though, I stil
recommend reading through this
section,
for it could be helpful later on.
Click
on the start menu and go to run, type in cmd, and click ok.
This
should bring up the command prompt.
From
here we wil do most of the hacking.
Now
I will be referring to certain commands that need to be inputted into the
command
prompt.
I
will put these commands in quotes, but do not put the quotes in the code when
you
type
it into the prompt.
I am
only doing this to avoid confusion.
Let’s
get back to the hacking.
Type
in “ping (IP address of the target).” For example in this tutorial, “ping
192.168.1.103.”
This
will tel us if the target is online.
If
it worked, it will look something like this (note, I have colored out private
information):
If
the target is not online, either switch to a different target, or try another
time.
If
the target is online, then we can proceed.

-[Part
3, Gathering the Information.]-
++++++++++++++++++++++++++++++++++++++++++++++++++
++++++++++++++++++++++++++++++++
++++++++++++++++++
++++++++
Now,
input this command “nbtstat –a (IP address of target).” An example would be
“nbtstat
–a 192.168.1.103.”
This
will show us if there is file sharing enabled, and if there is, it will give us
the:
currently
logged on user, workgroup, and computer name.
Ok,
you’re probably wondering, “What does all this mean to me?” Well, this is
actually
very
important, without this, the hack would not work. So, let me break it down from
the
top to bottom. I will just give the first line of information, and then explain
the
paragraph
that follows it.
The
information right below the original command says: “Local Area Connection,”
this
information
tells us about our connection through the LAN, and in my case, I am not
connected
through LAN, so the host is not found, and there is no IP.
The
information right below the “Local Area Connection,” is “Wireless Network
Connection
2:” It gives us information about the connection to the target through
WAN.
In my case I am connected through the WAN, so it was able to find the Node
IpAddress.
The Node IpAddress is the local area IP of the computer you are going to
break
into.
The
NetBIOS Remote Machine Name Table, give us the workgroup of our computer,
tells
us if it is shared, and gives us the computer name. Sometimes it will even give
us
the
currently logged on user, but in my case, it didn’t. BATGIRL is the name of the
computer
I am trying to connect to. If you look to the right you should see a
<20>.
This
means that file sharing is enabled on BATGIRL. If there was not a <20> to
the
right
of the Name, then you have reached a dead end and need to go find another IP,
or
quit for now. Below BATGIRL is the computers workgroup, SUPERHEROES. If you
are
confused about which one is the workgroup, and the computer, look under the
Type
category to the right of the < > for every Name. If it says UNIQUE, it is
one
system,
such as a printer or computer. If it is GROUP, then it is the workgroup

++++++++++++++++++

-[Step
4, Breaking In]-
++++++++++++++++++++++++++++++++++++++++++++++++++
++++++++++++++++++++++++++++++++
++++++++++++++++++
++++++++
Finally
it’s time.
By
now we know: that our target is online, our target has file sharing, and our
target’s
computer
name.
So
it’s time to break in.
We
will now locate the shared drives, folders, files, or printers. Type in “net
view \\
(IP
Address of Target)”
An
example for this tutorial would be: “net view \\192.168.1.103”
We
have our just found our share name. In this case, under the share name is “C,”
meaning
that the only shared thing on the computer is C. Then to the right, under
Type,
it says “Disk.” This means that it is the actual C DISK of the computer. The C
DISK
can sometimes be an entire person’s hard drive.
All's
that is left to do is “map” the shared drive onto our computer. This means that
we
wil make a drive on our computer, and
all the contents of the targets computer
can
be accessed through our created network drive. Type in “net use K: \\(IP
Address
of Target)\(Shared Drive). For my example in this tutorial, “net use
K:
\\192.168.1.103\C.” Ok, let’s say that you plan on doing this again to a
different
person,
do u see the “K after “net use?” This is the letter of the drive that you are
making
on your computer. It can be any letter you wish, as long as the same letter is
not
in use by your computer. So it could be “net use G...,” for a different target.
As
you can see, for my hack I have already used “K,” so I used “G” instead.
You
may also do the same for multiple hacks.
If
it worked, it will say “The command completed successfully.”
If
not, you will have to go retrace you steps.
Now
open up “my computer” under the start menu, and your newly created network
drive
should be there.
Now,
if you disconnect from the WAN or LAN, you will not be able to access this
drive,
hence the name Network Drive.
The drive will not be
deleted after you disconnect though, but you won’t be able to
access
it until you reconnect to the network.
So
if you are doing this for the content of the drive, I recommend dragging the
files
and
folders inside of the drive onto your computer,
because
you never know if the target changes the sharing setting.
Congratulations!
You’re DONE!
