- LordSkywalker, on 10/12/2007, -1/+55Good. Nobody will suspect anything when I pass a 700mb jpg file to a co-worker now.
- ggbs, on 10/12/2007, -1/+21here is the version with links enabled
http://zomgstuff.com/forum/showpost.php?p=16153 - Beaver6813, on 10/12/2007, -1/+19Could be used for storing torrents as images... :) a 1.5gb picture of a lizard ^^
- RedFoxEvan, on 10/12/2007, -1/+16# You will need the following.. Windows 2000 / XP
# Basic Knowledge of the Command Prompt
# WinRar
1. Gather your image and the files you wish to lodge into it. Here I have a meeting.txt which I will hide inside my toshow.jpg.
2. Add the files you want to hide into a new RAR archive. (so meeting.txt.rar created newly)
3. Open Command Prompt and go to the folder where your files are located, e.g., 'C:hidden'.
5. At command prompt type 'copy /b toshow.jpg + meeting.txt.rar lizard.jpg' (without quotes).
(toshow.jpg is the picture I want to show, meeting.txt.rar is the file to be hidden, and lizard.jpg is the file which contains both.
6. Now test the lizard.jpg by double clicking it, and verifying it still opens.
7. Now try opening that same lizard.jpg file from menu: file->open of WinRar. It will show the original hidden file meeting.txt.
Done !!!!! - killerbunnie, on 10/12/2007, -1/+11Dugg because it's a cool little trick, but not true steganography where the message is hidden within the picture. A good tutorial I've used is at http://www.onlamp.com/pub/a/bsd/2003/12/04/FreeBSD_Basics.html. Yea, it's using FreeBSD, but you should be able to find other tools to do the trick in other OSs.
- JC4P, on 10/12/2007, -7/+15This has been a /b/tard trick for a lonngg time...
- Cglass, on 10/12/2007, -0/+8Now I just gotta find something to hide, hmm
- synystar, on 10/12/2007, -0/+6Damnit. Now I'll be compelled to check every photo when I'm browsing Flickr for hidden messages.
- trunkster, on 10/12/2007, -2/+7I believe you are pretty much concating two files together and Winrar is just smart enough to ignore the junk at the beginning of the file (the jpeg image) and find the rar part.
- synystar, on 10/12/2007, -0/+5...
- synystar, on 10/12/2007, -0/+4This works exactly the same for .7z files.
P.S. Don't try to reply to a comment with "Sort by most Diggs" on. If you forget it can be very confusing =). - gogiel, on 10/12/2007, -5/+9To do it in Linux or other *NIX:
cat your_rar_archive.rar >> your_jpeg_file.jpg - synystar, on 10/12/2007, -1/+5bah... digg down.
- Vinthian, on 10/12/2007, -0/+3actually, the point was to make it a workable .jpg WITH another file in it. wonder if it works only with .txt's...
- williebee, on 10/12/2007, -0/+3Digg removed back-slash before colon. It must be there for this command to work:-)
"find /* -name '*.jpg' -exec rdjpgcom {} ;" - Wako, on 10/12/2007, -1/+4http://www.thetechtray.net/articles/rar.php
It has a video on how to do it. - sofa0ne, on 10/12/2007, -0/+2This reminds me of an program that I used long ago...
The program was called Camouflage and it worked pretty well...
I think you can still find the program here...
http://camouflage.unfiction.com/
It does function about the same...but for the lazier bunch...
Unlike the technique mentioned earlier, it is required to be installed on both systems.
I haven't checked to see how secure the files are once it has been used but it does allow for password protection.
Which brings up a good point that you can also password protect a RAR file.
Not that the password can't be broken, but it would make it a little more secure... - williebee, on 10/12/2007, -0/+2Or check all your jpg's with this command.
"find /* -name '*.jpg' -exec rdjpgcom {} ;" - konst3d, on 10/12/2007, -0/+2Niceeeeeee!
- Jack9, on 10/12/2007, -0/+2This was news back in 1996 when jap-pop was traded via image.
- Cubedude04, on 10/12/2007, -2/+4I remember this story a few months ago its still in my bookmarks
Dugg because its a cool trick others should know =D - RyuXenon, on 10/12/2007, -0/+2This was stolen, sadly. This Ugly-nerd and zomgstuff is lame. At the tutorial posted on zomgstuff save the picture of the lizard that he says he made...then open it in winrar and you can see the contents of it, meeting.txt or whatever. Open it up and it says go to http://www.thetechtray.net this guy stole the tut...
Check some of the posts of the forum like: "look someone dugg this now we are getting 300+ guests! wow omg!" - Thex1138, on 10/12/2007, -0/+1http://www.jjtc.com/Security/stegtools.htm
- Vinthian, on 10/12/2007, -0/+1tested... works.. awesome :D.
- Ninjamonk, on 10/12/2007, -0/+1I used to get my code out of my old place by simply opening up fireworks and pasting the text into a layer and then saving the file with the text off screen and then sending it that way. I did this using the PNG format. I should imagine the same method could be done in PS too.
- inactive, on 10/12/2007, -0/+1I remember seeing this in the projectW longe a bit back.
I seem to remember it working with other images, like PNG and BMP ect, i think it may have even worked with some media files like MP3.
also, i dont think it has to be a plain text file, i think you can also use encrypted ones. - drepmoreh, on 10/12/2007, -2/+3I remember reading about something similar years and years ago. The code logic behind it kinda bewildered me, but then again most things do.
It's a shame you have to be registered to see those links. - williebee, on 10/12/2007, -0/+1You can do this with linux, using wrjpgcom and rdjpgcom.
- donrichy, on 10/12/2007, -0/+1Cool, thanks by the tip!
- gogiel, on 10/12/2007, -2/+3cp instead of cat won't work:
cp: missing destination file operand after `your_rar_archive.rar'
Try `cp --help' for more information.
>but the signature bytes would be wrong and unix-like OSes rely on them rather than extensions to determine file types.
It works, just try. - inactive, on 10/12/2007, -0/+14t HIT Mail Privacy LITE http://4t-niagara.com/hitmail.html is an easier way of encrypting text into an image.
- finnishgeek, on 10/12/2007, -0/+1Does anybody a link to the flash animation where UgLy-NeRd's profile pic came from? I remember watching it a fews years ago and can't remember were.
- ramsinks.com, on 10/12/2007, -1/+2Go to www.thetechtray.net for the secret instructions ;)
Just use textedit in OSX - open .jpg with it - go all the way down after the text - put your text in - save. done. - r121, on 10/12/2007, -0/+1I used to use that program as well. The "password protection" was very weak though, it did encrypt your hidden file so it wasn't easily readable, but the encryption wasn't based on your password. I found that you could hex-edit the file and blank out the bytes where the password was stored, and you could extract the file without a password.
- jmz635, on 10/12/2007, -0/+1see here http://digg.com/security/Hide_that_pr0n
- jmz635, on 10/12/2007, -0/+1I don't mind.. except they added my credit later by the looks of it.. and they ***** stole my bandwidth..
DONT ***** HOTLINK
oh, see http://digg.com/security/Hide_that_pr0n too - Vinthian, on 10/12/2007, -0/+1But then you won't be able to open it with winrar :(. JPG files are special because they probably have a start and end tag, which tells a program where it starts and stops reading the jpg image itself. Adding more text to the end doesn't do anything, but adding a winrar or 7z file does :D.
- inactive, on 10/12/2007, -1/+2concatenating is the word, not concating.
- ElJayDaGreat, on 10/10/2007, -0/+0is there any program to automate this?
- djLsv, on 10/12/2007, -0/+0Why is this front page news?
- inactive, on 10/12/2007, -1/+1OLD OLD OLD
This is how weve been hiding our kiddie porn for years on /b/. - BostonMark, on 10/12/2007, -2/+1Or how about you just use TrueCrypt and you're all set.
http://www.allthingsmarked.com/2006/09/30/howto-securely-open-truecrypt-volumes-in-one-click-redux/ - steal_apps01, on 10/12/2007, -3/+2More UgLy-NeRd eh, I like this guy.
- UgLyNeRd, on 10/12/2007, -1/+0I didn't steal it. I posted the source of that at the very top of the page. Noob, learn to ***** read.
- inactive, on 10/12/2007, -2/+0David Copperfield, learned to use PC :D
- dj_sea2005, on 10/12/2007, -6/+4or you can use GRL RealHidden. a free program for windows that lets you hide any type of file inside any other type of file. complete with password protection and compression:
http://www.grltechnology.com/index.php?ID=18 - subxero37, on 10/12/2007, -2/+0This works under Windows 9x/ME, and DOS as well (provided you've got an RAR decompression utility for these operating systems.) The copy command is just the same.
- ConiX, on 10/12/2007, -2/+0isn't nicer to use built-in Windows command prompt instead using external software? :)
- phenolholic, on 10/12/2007, -6/+1a simpler method: rename meeting.txt to lizard.jpg ...by default, an image viewer will try to open lizard.jpg, only to find its not viewable. noone will know lizard.jpg is really a txt file other then the people who intend to know
- Raider8654, on 10/12/2007, -6/+1There is also another steganography program called IceMaker which allows one to conceal files up to 1/3 the original image's size into the image. Since a 640x480 bitmap picture with 24bpp is 900kb, you can hide 300kb of information in that picture. So it does not work with JPEGs, as they are lossless, it does work with bitmaps.
You can find it here:

Look for "IceMaker 6000". -
