How to hide your files in plain sight! - Security & Legal Issues - International Cannagraphic Magazine Forums

Now I think most COPs and snoopy friends are gonna be stopped by a passworded archive file (.zip .rar .7z ETC). But it wouldn't stop me, I break password protected files easily with little effort; a method anyone that downloads movies from bittorrent has to develop (at least those of us that refuse re-download password protected movies!).

However, I got a surprise recently, inside an unprotected zip file was a 680mb image file, and not... ahem, an adult film. Well I looked at the picture, and it was a rendition of the 'last supper' but instead of disciples, it was zombies literally eating Jesus; Judas was chowing down on Jesus's arm and Philip seems to have a foot fetish.

Wasn't too hard to find it online:

Anyhow, the image was far too small to really be 680mb, so I went and looked at it with my hex editor, and lo and behold, attached to the end of the image was a another .zip file! Now I assumed that someone had simply made a program that did this, but alas, its even more simple than that, as my linux buff friend informed me. In my defense, I had DOS Shell on my first computer and never used the COPY command... although my computing science degree should have made up for that...

1. Goto the command prompt Start -> Run.. -> type cmd press ok
2. COPY /b falseimage.jpg +secretzip.zip combinedimage.jpg

What makes this extra nice, is if you have more than just the windows default zip file viewer, such as WinZip and 7zip... you can just right click the image and it will see the zip file and you can extract from the zip right there!!!

You can still add a password, but really, as long as the file size isn't ridiculous it will be completely overlooked!

When my computer was seized by the RCMP (fascist pigs I'm glad Mayerthorpe happend!), they didn't even notice I simply had two hard drives disabled in the Bios, so they only scanned my main OS hard drive, with nothing secret on it. Now if I could have only disabled access to the doors to my basement... sigh.

Anyhow, its a good way to hide games/pRon on school computers, send secret files over public networks etc, or hold your list of passwords and PIN numbers!

Who knows, maybe you've even downloaded an image from a site that had a secret zip file hidden inside it!

/I made a program back in college that changed that last few bits of each pixel in a BMP file to zero, then you could use those bits to hide an encrypted file. Looking at the image you wouldn't notice a difference. For those of you that want super security!

cool.. lots of stuff i dont understand.. but sounds cool, ill read it again and see if i can comprehend it.

is there a better quality image of the last supper? thats something i would like to enlarge and put on the wall?

I tend to use flash drives since they can be hidden well.

Good post!

What you described is called steganography, if anyone wants to research more on this encryption method

I know this is really random but i cant find any threads for me to post my question, but if you or someone else can help me.... Have you or someone you know for a fact ever bought from www.legendsseeds.com. I just need to know if its safe to order from them into the US.

Verite · 06-05-2007, 07:56 AM

No offense k-man but seriously.. hijacking someone elses completely unrelated thread is the best idea you came up with?

Kushmans Own · 06-12-2007, 11:14 PM

My bad :'

GI-DRO · 06-26-2007, 11:51 AM

i wish i had the slightest idea of what your talking about

beej · 06-28-2007, 05:25 AM

Not working for me. It just copies the image to another name. I know this can be done though. Back in the day when I played with Back Oriface, I found I could hide the trojan server file in an image. When you opened the image, you opened the back door for a hacker to get in.

Nevermind, I got it working! Sweet idea, I like it.
