Hide your file in video!

[DmitriyV]

MSU StegoVideo released as standalone program.
This is the simplest way to hide information in file, that will be compressed.

• Put your file into video
• Compress video
• Decode information from compressed file!
• Enjoy!

Small text files and maximum redundancy is recomended:



Do you have installed codecs on you PC? You can test our program, it's compatible with all codecs.

This strikes me as mighty useless. Interesting, but useless.

It would be cool if you could convert any file to DV-AVI. Instant $5 14gig external HD's.

use winrar to rar up a folder containing your "data".
rename it to .avi.
use winrar again or .7z to archive again.
and call it then what you like,only you know the original name,and file type.
hey presto,easy peasy!

This appears to be a playable video though, the file is hidden in the data stream. I like my idea best.

I wonder if you could hide a virus in a video and infect anyone who plays it. That would be bad news.

It's been done with still images so doing the same in video would be no problem.

Shhhh,you'll give cyber bandits ideas

From playing a video AFAIK there's no way that it can be done. On the other hand as far as opening a file that was hidden in a video yes that would be possible.

You'll notice that you can only put small files in it, the app probably creates a valid video with "noise" that it can interpret and reassemble.

That's the first thing that came to my mind.
I really don't see any legitimate use for this.

It's quite possible and has even been done. The basic technique is to structure the image so that decoding it causes a buffer overflow on the stack. One that overwrites the return address from a procedure call. When the procedure tries to return to the calling function it returns to the address specified by the buffer overflow instead -- the virus/worm code. This is a very common type of attack.

Stegonography (for example http://www.jjtc.com/Steganography/) is nothing new and is an important tool. Suppose you live in an oppresive regime which is committing atrocities. If you send an email to your family describing the crimes you'll quickly end up in jail. Or dead. You could hide the message within a picture or video and get the message through secretly. Of course, terrorists and organized criminals can use these techniques too...

I know of the the vulnerabilites that was present in images but I never heard of it in a video. From My undrstanding the image threat has been negated and only MS was vulnerable. I haven't heard of any other viruses your able to embed within a dta file like a video or image. I'm sure there's some 14 year kid working on it as I type this though.

You can...

I'm pretty sure that there is a Windows version of a such a program too...

Well I guess that would be a problem for me but they would first have to pay me to install it. That's the first I heard of virus in a video..... according to the article it was simialr to the JPEG vulnerability. Realistically chances of getting a virus at this poin and time from a video file is nil, who knows maybe that could change.

They can hit you with a virus in video.

Video is used as container. You can save virus into ordinary file archives!

DmitriyV,

Thanks for the info and link. I wasn't aware there was a freeware video-steganography program available. I look forward to playing with it when I get some free time. Do you know if the resulting file is susceptible to statistical analysis? Just curious.

To those of you concerned about viruses, ANY data file (mpeg, avi, jpeg, zip, rar, or even text files) can contain a virus, but there is absolutely no danger unless the virus is allowed to execute. The danger comes when a program accessing the data file erroneously enables the virus to execute.

Vulnerabilities to stack overflows, heap corruption, or deliberately malformed input don't have to exist in programs, it's just faster, easier and cheaper to use existing insecure libraries, not devote the extra time needed to fully validate input, and not review the code specifically looking for vulnerabilities. On the other hand, these same practices do make software affordable.
