CREATING TROJAN VIRUS

CREATION OF TROJAN VIRUS

The Trojan horse which I have made appears itself as an antivirus program that scans the computer and removes the threats. But in reality it does nothing but occupy the hard disk space on the root drive by just filling it up with a huge junk file. It fills up the hard disk space. As a result the disk gets filled up to 100% within minutes of running this Trojan. Once the disk space is full, the Trojan reports that the scan is complete. The victim will not be able to clean up the hard disk space using any cleanup program. This is because the Trojan intelligently creates a huge file in the Windows\System32 folder with the .dll extension. Since the junk file has the .dll extension it is often ignored by disk cleanup software’s. So for the victim, there is now way to recover the hard disk space unless reformatting his drive.

The algorithm of the Trojan is as follows

1. Search for the root drive

2. Navigate to WindowsSystem32 on the root drive

3. Create the file named “spceshot.dll”

4. Start dumping the junk data onto the above file and keep increasing its size until the drive is full

5. Once the drive is full, stop the process.

You can download the Trojan source code here.

NOTE:

THE CODE IS DEVELOPED BY C LANGUAGE.

IF YOU WANT TO CREATE .EXE APPLICATION MANUALLY PLEASE USE C EDITOR

EX: - BORELAND C, TURBO C

PROCESS TO COMPILE C PROGRAM

1. OPEN C EDITOR

2. OPEN CODE FILE

3. COMPILE THE PROGRAM

4. RUN THE PROGRAM

NOTE: THE .EXE FILE GENERATE AT DEFAULT DIRECTORY BIN

How to remove the damage?

How to remove the Damage and free up the space?

To remove the damage and free up the space, just type the following in the “run” dialog box.

%systemroot%\system32

Now search for the file “spceshot.dll“. Just delete it and you’re done. No need to re-format the hard disk.
