oh, so, must have been caused by the bat to exe conversion. sad to hear.
thanks for letting me know.
I added that in the thread.

No problem keep up the good work!

Your link doesn't work for me. It says "La risorsa richiesta รจ accessibile qui" (don't know what that means)
Why did you convert your batch file to an exe? The batch file should be compatible to every Windows version and it will be less suspicious as you can see the code.


RE: Hide files inside images - noize - 02-01-2013

Yeah, you can download by clicking on "qui".
Anyhow I had made this a bit earlier than when I posted it. I uploaded the zip with just the exe as didn't thought there would be problems of compatibility but then I'm just to upload also the batch.
--------------------------------
Edit: Just fixed the links so it downloads automatically.

For me at one doesn't work?
It is impossible to hide the file under the picture.
I will be very grateful if explain as to make the file under the picture.

You can only hide archives. I wrote about it under the "howto" and when trying to hide ("Choose the archive to hide: "). maybe I should have said so also in the thread but I thought that saying to read the howto would be fine.

It is not impossible.

Solixious made a tool demonstrating that text can be hidden: http://www.hackcommunity.com/Thread-JAVA-Solixia-v1-1
Here is the another tool that hides images: http://www.hackcommunity.com/Thread-Release-Source-ImageSteg-hide-one-image-in-another

Actually you can hide arbitrary data in a picture. A simple technique is using the least significant bit of a pixel. As each pixel has three colors, you can hide 3 bit per pixel, making it possible to store 15 KB of data in a 200x200 sized picture.
Google "image steganography" to get to know more about this topic.

In the case of this thread a simple trick is used to "hide" an archive behind a picture. The archive is just written behind the picture at the end of the file. If you click on this hybrid file and is has an image ending on Windows like .png, an image viewer is opened and you see the picture, as the viewer interprets is as an image. If you change the fileending to i.e. .zip it will be interpreted as a zip file and an archive program like 7zip can extract it.
