i hid a copy of windows 3.1 inside this photo just open it with winrar or
7zip that is if theres some sort of system that would remove the files from the photo its self on this image board

Someones discovered steganography. What will really boil your noodle is when you start realizing tons of images deploy this method on Zig Forums and it has been used for secret communications for years.

Is this even steganography? It's akin to concatenating two files together.

Jeremiah Lewis

No it's not steganography and is simply concatenating two files together (you're correct).
The easiest and simplest form of steganography is least significant bit encoding but that's not what this is.

I remember when you would be autobanned on halfchan for stapling an MP3 to a picture, way back in the days before GG. Before then, it was the way people would have "name that tune" threads with a bunch of "play this picture in winamp" images.

same file format
No as the data could just transfer over
different file format
Usually this does the trick but some stengraphy methods use the individual pixels to transmit data and not the formatting of such. For those kinds of things you need to print out the image and blur it up a little with water then scan it back into your computer and wala, the image is clean now.

Why, are you annoyed someone might mention that images downloaded from major services like faceberg or twitter actually have CP embbedd in every single last image in secret so that the governments that make CP illegal can just arrest you without explanation for browsing goybook once? Well this is indeed a thing. But the algorithm to re assemble the CP is a closely guarded trade secret by intelligence agencies/mossad, who planted the CP in the first place being the faggots that they are.

Benjamin Reed

I think you should blur and rescan the image several times for maximum safety as the printer could be inserting shit into the image too.

Batch convert your images to another image format (or same image format, really); this should get rid of lumped data. You may also use lossy compression algorithm to remove data hidden in least significant bit of RGB triplets. Don't forget to discard EXIF and meta data.

Dominic Roberts

Appending a file with copy is baby's first stego. Try embedding the file directly into the image data with something like steghide. Much much harder to detect and filter! 😹

fwiw, here's the first INTERNET SECRET MESSAGE I ever noticed...

GIF

....filesize 20kB
something suspect is going on, I had to thinks...

As other EWS fans might now, a few years later an artist calling themselves "TDK" appeared with very suspicious art style. Schwartz denied up-and-down all this illegal art that might destroy a budding animation artist's career chances was him... I invented up a way to make a hash of a JPEG's EXIF, showed all the "TDK" pics had the same hash... and then ran it through my archive of the entire image collection of the 1994-era Internet.. and the only artist whose images generated the same hash was a Eric W. Schwartz.

This has nothing to do with being an edgylord who can distribute the Christchurch /pol/tard's Manifesto in a way that ((they)) can't prevent, sorry.

Is there a way to mass detect attached data on images? I got like hundreds of millions of pictures, cleaned of meta data and archived with winrar. Could be interesting because they date back to the middle of the 90s.

Joseph Moore

Is there a way to mass detect attached data on images?
Tough call. I'm only vaguely aware of this stuff, I'm not a pro on the topic. I think you'd have to suspect there's something weird going on and you'd have to guess how the data (and what type of data) has been hidden inside the file...

Assuming we're talking about two (or more) files lumped together, you could recognize clandestine data by guessing it's proper size, and compare to the actual size of the file; but that would be tricky since compression algorithms are involved.
You could also check for specific signatures within those files (for instance see if a "%PDF" string is present in a non-PDF file, or maybe more than one image header like "GIF89a", "PNG" or "JFIF").
Ultimately, you could brute-force your way through and attempt to decode full streams of data out of files (which is probably the way to go in this case)...

There are other techniques to hide the existence of the data, like the least significant bit explained earlier (which would be revealed if you isolated those bits into a black and white image; the result would be a very noisy canvas that bares no resemblance to the source picture, since those bits are completely unrelated to the actual colors that makes the image), or two-file masks (where you combine two images and the result is the hidden data).

Either way, we're talking steganography (which is the process of hiding the existence of a message), and not cryptography (which is the process of concealing the meaning of a message, not its existence). In short, you could have an encrypted lump hiding beneath a normal file and analyzing a whole stream wouldn't return a single thing, because you'd assume the information is clear.

If you want to retrieve the information, there are some brute-force data extraction tools designed for video games resources files that could be useful here, but that would still require doing it by hand I think.
If you want to get rid of the secret lumps, I would recommend the lazy way out, such as using a batch image editing program like irfan, acdsee, xnview or whatever: select all and convert to a proper image file (which would discard all extra data - be careful not to convert image types to different images formats that do not support specific features, like transparency or animations).

That's all I have.

Damn. I saw a good presentation from some hacker con on just this subject a few years ago. It was on non cryptographic means of hiding data from law enforcement. It also mentioned soldering flash memory directly to the USB hub on the Mobo, because it's not often they do a thourough physical inspection. I can't find the damn talk on YouTube now. I remember it was given by some skinny dude that was drinking beer during the whole talk and was fairly drunk by the end. I don't remember what con it was, though.
