HOW ARE THE SYSTEM BEING COMPROMISED/HACKED?

Lets Send the server file (we will call it netbusserver.exe)
to you via E-Mail.
This was how it was originally done.

The hacker would claim the file to be a game of some sort
in order you dont recognise it.
When you then double click on the file, the result is nothing.
You don’t see anything. (Suspicious :( :()
Note: (No matter many times have you double clicked on a
file someone has sent you and it apparently did
nothing)
i remember the same story when one of my friends sent
me the file in the similar way ..
well i was not so much aware of it since i trusted him..
but apparently it was a virus of the similar kind attached
with a wallpaper file..
Now here we continue
At this point what has happened is the server has now been
installed on to your system. All the “hacker” has to do is use the
Netbus Client to connect to your system and everything you
have on your system is accessible to this “hacker”(strange but true)
With increasing awareness of the use of Trojans, “hackers”
became smarter and advance antivirus used to block such clients
are every increasing in the world, Hence we move on to method 2.

Method 2
Our Objective is to explain How to Get you to install the server on your system :).

Now Let’s see, how many of you receive games from friends?
(beware "Do trust anyone blindly,Like i did ")
Games like hit gates in the face with a pie,GTAalso wallpapers,screensaver.
Perhaps the game shoot Saddam?
There are lots of funny little files like that.
Now we will show you how someone intent on getting access to
your computer can use that against you.
There are utility programs available that can combine the
(“server” (a.k.a. Trojan)) file with a legitimate “executable
file.” (An executable file is any file ending in ".exe" extension ). It will
then output another (.exe) file of some kind. Think of this
process as mixing poison in a drink mixed in a sweet dish.
For Example:
Mango Juice + Poison = something
Now the result is not really Mango Juice anymore but you can
call it whatever you want. Same procedure goes for
combining the Trojan with another file.
For Example:
The “Hacker” in question would do this: (for demonstration
purposes we’ll use a normal chess game)
Name: chess.exe (name of file that starts the chess
game with .exe extension)
Trojan: netbusserver.exe (The Trojan virus)
The joiner utility program will combine the two files together and output
1 executable file called:
.exe eg) abc.exe
This file can then be renamed back to chess.exe. It’s not
exactly the same Chess Game. It’s like the Mango Juice,
it’s just slightly different.
The difference in these files will be noticed is in their size.

The original file: chess.exe size: 50,000 bytes
The new file (with Trojan in it): chess.exe size: 65,000 bytes
(Note: These numbers and figures are just for explanation
purposes only original may differ)
The process of joining the two files, takes about 10 seconds to
get done. Now the “hacker” has a new chess file to send out
with the Trojan in it.

(?). What happens when you click on the new chess.exe file?

->: The chess program starts like normal programs. No more
suspicion because the file did something. The only difference
is while the chess program starts the Trojan also gets installed
on your system.
Now you receive an email with the attachment except in the
format of chess.exe.
The unsuspecting will execute the file and see a chess game.
Meanwhile in the background the “Trojan” gets silently
installed on your computer :) hmm.
If that’s not scary enough, after the Trojan installs itself on
your computer, it will then send a message from your
computer to the "hacker" computer telling him the
following information.

Username: (A name that victim system has)
IP Address: (Your IP address)
Online: (Your victim is online its the status)

So it doesn’t matter if you are on dial up. The potential
hacker will automatically be notified when you log on to your
computer.
You’re probably asking yourself “how likely is it that this has
happened to me?” Well think about this. Used in
conjunction with the above mentioned methods can make for
a deadly combination.
These methods are just but a few ways that “hackers” can
gain access to your machine.
Listed below are some other ways they can get the infected
file to you.
