How to Make a
Trojan Horse
Most of
you may be curious to know about how to make a Trojan or
Virus on your own. Well, here is an answer to your curiosity. In this, post
I’ll show you how to make a simple
trojan on your own using C programming language.
This trojan when executed will eat up the hard disk space on the
root drive (The drive on which the Windows is installed, usually C: Drive) of
the computer on which it is run. Also, this trojan works pretty quickly and is
capable of eating up approximately 1 GB of hard disk space for every minute it
is run.
So, I’ll call this as Space Eater Trojan. Since this program is
written using a high level programming language, it is often undetected by
antivirus programs. The source code for this program is available for
download at the end of this post. Let’s see how this trojan works:
Before I move on to explain the
working of this program, you need to know what exactly is a Trojan horse and how it works. Unlike what
many of us think, a trojan horse is not a virus. In simple words, it is
just a program that appears to do a favorable task but in reality
performs undisclosed malicious functions that allow the attacker to gain
unauthorized access to the host machine or cause a damage to the computer.
