Actually real steganography is done in another way, but similar results. Change the least significant bit (LSB) of rgb element in each pixel so that its odd or even. The pattern of odds and even ( 0 and 1 ) will give you a hidden message when you extract. This way you’re basically altering the real image im a way its not distorted instead of adding to the image.
you can hide zip archive in jpg images using the copy comand in cmd. opening it in 7zip will open the archive, but otherwise it will open as a normal image
Works because a ZIP archive has the metadata at the end (if you add more files to an archive, its metadata is going to grow, so if it's at the end you don't have to move as much data to make space). Learnt about that because back in the 90s, I had some installer that was a shell script with appended zip archive.
@@Ph34rNoB33r It's even simpler than that, it even works with e.g. RAR (which doesn't concentrate metadata on members at all, just adds a list of offsets at the end when you add a "quick open header" to RAR5 archives) or 7-Zip (which has the table of contents at the beginning). Archivers just scan the file until they find an archive file signature to support self-extracting archives, which are just an archive appended to an unpacker executable.

This is great! This was my first time trying steganography and using python and this was super interesting! You did a great job of walking through which each step's purpose was!
I really appreciate these kind of videos. You explaining Stuff which I didnt know existed. Really Cool, now I'm never gonna click a jpeg lol.Hope you get a 100k in a couple of weeks.
I downloaded a random image off the internet so I could do this on. I couldn't figure out why I couldn't get it to read, I was able to write to the jpg. Turns out it already has another hidden message inside it that's more complicated to extract lol.
Was a bit disappointed you just appended data to the image file, lots of image upload services just strip data past the end. You can have more success with adding application-specific JPEG segments (APP2..APP15 - APP0 is already used for JFIF and APP1 for Exif) or even encoding hidden messages into the actual quantization matrices.
Thanks for the content 👍. I've got a question please. Is there a way to automatically extract and launch the executable file in the background after reaching the EOF flag of the image
A problem I found with the hello world part is the FF D9 is always at the end of jpg file, BUT it does not mean FF D9 cannot appear elsewhere in the file. In my case, I found a jpg file that had FF D9 in 2 other separate spots than at the end.
No need for python here. For bash/zsh, this will do: `cat heart.png >> photo.jpeg`. It will work with any other file :D Windows shell uses `type` instead of `cat`.
THANK YOU. I have been looking for this tutorial for ages. You can't imageine how much time I spent trying to find a way to do this, thank you so much. btw I'm downloading this video so I won't lose it again
bruh. here I thought you were actually gonna do something smart with pixels. you're also banking on the parser not checking for bigger file size, I doubt it's actually part of the spec that you can just have whatever there. Basically making a 16m long video to say "do a concat".
Quick question - Is it possible to execute a standalone .exe file (which is injected into the .jpg file) when a user opens the .jpg image? Great video btw!
No, the executable file has to have a special byte sequence at the beginning - in x86 times this was "MZ…" if I remember correctly - look it up with a hexcode editor. Maybe for x64 architecture, a variant is used, maybe it is different. But the file has to start with that.
No, its not possible. As i said in another comment: Thats not how it works at all. You can hide a virus / malicious code in a JPEG or any other file really, the thing is that it doenst get executed because its not an executable. When photoshop for example reads the data from the JPEG file it only reads it (to the FFD9) but it doenst execute the rest of the binary lol. The only way to get a virus from opening a jpeg file is with a third party image reader than executes the bytes after the image.
But why? It is good for nothing. Moreover, exe files have inital sequences, too, and if antiviral software detects these inside an image file, they will got to defcon 1. You actually increase the probailty of being detected dramatically.
So this is usable but wouldn't hide anything from a bytewise search or anyone who knows anything about programming. There's a much better way to hide stuff in images, you write your info into the least significant color bits of the image. If you do it correctly you can even do it with a jpg but a non-compressed file is easier. You can literally just print text that wont be visible in the image and it won't look like a addended file. But if you're going to do this compress your data and at least terminate it with FFD9 so a casual look still looks like a JPG.
I bought a reference 5700 (non-xt) when they were being discontinued for $270. I spent another $70 to get the Artic Freezer aftermarket cooler. Then flashed it with the XT bios. Since then, AMD has only improved the drivers and performance. The only times I've had any issues were pushing unstable overclocks or with game titles that are notoriously bad to begin with.
There is nothing wrong with this approach :p. The target of this video is beginner CS students that are interested in cybersec, I think, so they are less comfy with cmd or sh D:
Very informative. But I've a question. Let's say I download some jpeg by mistake, which has hidden exe. How can someone make this exe extract itself and run on my device? What are the steps I can do to prevent that from happening? Because tbh there is no way to know which image is infected and which isn't, and it's not possible to stay away from downloading images at all. Should I write a python code to check the images by myself? And will that exe stay inside the image safely till I'm able to verify the image using python?
I think many social websites just get rid of everything you hidden in the image. They process the image and compress it (and maybe inject their own metadata)
Mind if you do come across something in the wilds of the net I wouldn't run it unless you really know what you're doing. (Sandbox VM, profilers, decompilers, etc)
this is cool, by obvious for people searching for a payload. Why modify the pixels like the png steganography tutorial don't work with jpeg? Thank you btw for this video
The thing that is not clear to me is : when you search for the index in the file, how are you sure that the bytes FFD9 do not appear also before the end of the file image?
I once took a peek of what's inside the APK of a mobile game I have and I see only one image file with size like 100MB. The photo is damaged or nothing to display so I suspect the files and resources are in that image file. After watching this, everything becomes clear now.
this is no hiding because such thngs become well known and soon tools to extract such hidden info starts surfacing not to speak of such videos explaining it all in baby steps to python ignorants or python lazy ... give us true steganography algorithms
Does this work as the old DOS copy /b command? If so, if I remember correctly, you can skip the extraction part and just change the extension to which part you want to see (e.g. photo.jpg opens in photo editor, photo.txt opens in notepad and shows just the text Hello world)...
Copy yes true, but when change extension then the program start to read every time from first byte, not from the second file hidden inside, so you will have simply a notepad full of ascii characters before the final correct text
Thats not how it works at all. You can hide a virus / malicious code in a JPEG or any other file really, the thing is that it doenst get executed because its not an executable. When photoshop for example reads the data from the JPEG file it only reads it (to the FFD9) but it doenst execute the rest of the binary lol. The only way to get a virus from opening a jpeg file is with a third party image reader than executes the bytes after the image.
Hmm.. Interesting. So this "FFD9" will occur only once even if jpeg file is hundreds of megabytes in size, and/or having gigapixels inside it? Hard to believe it, but it's math I guess..
It basically is defined in JPEG format to be impossible anywhere else. In encoded JPEG data you cannot ever get value FFD9 until the end. It may seem like encoded nonsense but it actually is all intentionally designed as such! :D
