Hiding a file inside an image file.

Try: unzip picture2.jpg

It dumped all the zip contents on my desktop. This is very interesting, thanks for sharing it.

 

i am not sure if you are just messing around or actually want to hide a file, but if you create a disk image in disk utility and password it, it effectively does the same thing. ie you are unable to look inside the 'disk' unless you type in the password. i have not checked if you can access it through terminal, but i highly doubt you can without the password.

 

But all this method does is append another file to the end of a picture. Programs like File Juicer will spot these right away. Find a decent steganography application for OS X and it will spread the file to be hidden around inside of the picture so that it won't be so easy to find. Some will even handle encrypting the file first and then hiding the resulting cryptext inside of the picture. If you are really looking to hide a file, this is the way to do it.
