After a long time today I am back with some interesting topic which is actually very tricky. This post will actually show a trick which will help you to develop steganography with the help of simple DOS commands. Before that lets learn what exactly steganography is and why it is used.
Steganography is art and science of hiding facts behind a false or useless but interesting element. In this process no one other than the sender and the and the recipient can view this. Cryptography is combined with steganography just for the reason that, if also the message is discovered it cannot be read. The main difference lies in the existence of cryptography and steganography.
In Cryptography one can know that a message is encrypted. But in Steganography one cannot know or observe about it simply because its hidden behind an image, video or an audio etc… which without keen observation might go without any suspicion. Steganography was widely used by the terrorists. In 9/11 attacks of the World Trade Center Stenography was used at a higher rate. This was discovered during the post attack investigation.
Hence friends it depends upon us how to use things positively or negatively. Following is the trick how to use it.
Open Command Prompt or Go to Start > Run, type cmd.
Now type copy /B original.jpg + archive.rar new.jpg
In the above command Original.jpg is any image in which we are going to embed archive.rar file.
If you open new.jpg with some picture viewer it will be a normal image, but when you open it with WinRAR for example it`ll show you the contents of archive.rar.
It will also work with different types of files.
