How to Hide Data in Image, Audio & Video Files: Steganography
Ever wondered to know how to hide secret messages in images, audio and video files? Well, in this post I will take you through a concept called steganography using which, it is possible to hide your secret information in image files, songs or any other file of your choice. At the end of this post, you can also download free stegnographic tools and start hiding your data.
What is Steganography?
Steganography is a means of obscuring data where secret messages are hidden inside computer files such as images, sound files, videos and even executable files so that, no one except the sender and the receiver will suspect the existence of stealth information in it. Steganography may also involve the usage of cryptography where the message is first encrypted before it is concealed in another file. Generally, the messages appear to be something else such as an image, sound or video so that the transfer of secret data remains unsuspected.
The main advantage of steganography over other methods such as cryptography is that, it will not arose suspicion even if the files fall in the hands of a third party. Unlike cryptographic messages, stegnographic messages will no way attract the attention of a third party by themselves. Thus stegnanography has an upper hand over cryptography as it involves both encryption and obscurity.
What are the Applications of Steganography?
Steganography is mainly used to obscure confidential information/data during storage or transmission. For example, one can hide a secret message in an audio file and send this to another party via email instead of sending the message in the textual format. The receiver on the other end will decrypt the hidden message using the private decryption key. In a worst case scenario, even if a third party does manage to gain access to the email, all he can find is the audio file and not the hidden data inside it. Other usage of steganography include digital watermarking of images for reasons such as copyright protection.
Eventhough steganography has many useful applications, some may use this technique for illegitimate purposes such as hiding a pornographic content in other large files. Roumors about terrorists using steganography for hiding and communicating their secret information and instructions are also reported. An article claiming that, al-Queda had used steganography to encode messages in images and transported them via e-mails, was reported by New York Times, in October 2001.
How do Steganography Tools Work?
Stegnography tools implement intelligent algorithms to carefully embed the encrypted text messages or data inside other larger files such as an image, audio, video or an executable file. Some tools will embed the encrypted data at the end of another file so that there will be enough room for storing larger data.
There are many steganography tools available online but only a few are able to work flawlessly. I did not find any tool that worked perfectly on both small and large data. However I have managed to develop my own tool that can work perfectly on all types of files and all size of data. The tool is called “Stego Magic“. You can download it from the following link.
Download Stego Magic
Download StegoMagic.zip
The zip file contains two versions of Stego Magic: One for encrypting the text messages and the other for encrypting binary files. StegoMagic_TXT can be used to hide text messages in other files such as an image or a sound file. StegoMagic_BIN can be used to hide one binary file in another such as an executable file inside an image or an image inside a video file.
With Stego Magic, there is no limitation on the size and type of the file that you are intending to hide. For example, you can hide a video of size 1 GB in an image of size 1 MB or hide an executable file inside a WORD document. The tool is pretty straightforward to use and requires no special understanding of the concept.
At the end of the encryption process, a secret decryption key will be generated and the same is required during the decryption process.
How to Use Stego Magic?
Suppose you want to hide a text message inside a JPG file:
1. Place the JPG and the text file (.txt) in the same folder as that of StegoMagic_TXT.exe
2. Run StegoMagic_TXT.exe and follow the screen instructions to embed the text message inside the JPG image.
3. Note down the secret decryption key.
Now you can send this image to your friend via email. To decrypt the hidden message, your friend should load this JPG file onto the Stego Magic tool and use the secret decryption key.
How to protect USB Pendrives/Flashdrives from VIRUS ?
Lets Protect USB Pendrives / flash drives from Viruses.
Most often our system get infected with virus soon after a USB pendrive has been plugged in. These days it is so easy to get infected by viruses by plugging in a pendrive to your system from unknown source (may be your friends one or your college desktops).
Not all the security programs can defend your pc against the virus attacks carried out through pendrives. But if we can take necessary steps, then we can be safe from such viruses, worms and spywares spreading through pendrives/ flash drives.
So here are some software’s that can efficiently protect your system and pendrive from unknown threats ad viruses.

USB Guardian
USB Guardian blocks any programs from being automatically executed from a pendrive and thereby it isolates the autorun directives on the removable device.
USB Guardian then scans for any autorun.inf file on the flash drive to check whether it references to any additional files on the pendrive. If any such files are found it automatically blocks those files.
The Locked files will be inaccessible by any other program and you can unlock it using USB Guardian itself if you think the program is harmless. USB guardian is free for use and is 2.96 MB in size.

Computer Viruses for Dummies
. Feel free to skip chapters that aren’t of immediate interest. Want to start at the last page? You’re the boss; everybody knows who done it anyway — that sinister virus. If you’re looking for particular information, you can go about it in several ways. You can use the Table of Contents to find the area of immediate interest. Or, you can look at the Index to find a particular word or concept. Finally, at the top of each page, a running head tells you what chapter and what part of the book you’re currently in. Feel free to just skip around until you find the information you seek . . . unless you already have the queasy feeling that your computer may be infected. Then your best bet is to “start at the beginning” (as Lewis Carroll recommends) and explore from there.
HACK! HACK! HACK!
Hi friends am going to add some of the rare Hacking books in this blog so please keep visiting frequently…
books like
Pop a banner each time Windows Boots
To pop a banner which can contain any message you want to display just before a user is going to log on.
Go to the key :- HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WinLogon
Now create a new string Value in the right pane named ‘LegalNoticeCaption’ and enter the value that you want to see in the MenuBar.
Now create yet another new string value and name it:
‘LegalNoticeText’.
Modify it and insert the message you want to display each time Windows boots.
This can be effectively used to display the company’s private policy each time the user logs on to his NT box.
It’s ‘.reg’ file would be:
REGEDIT4 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Winlogon] “LegalNoticeCaption”=”Caption here.”
