Hiding Files In Images - Kali Tutorial Steganography 

Son, why your cat images weight 15GB per file?

"Let's use a very secure password..." "password"

brb imma hide entire gta v game in a cat photo and upload it to google unlimited photo storage

‘Don‘t hide files in publicly available images.‘ I guess my nudes are out of question then.

If article 13 and 11 were accepted memes would be sent using this method

you look like someone who would hide files in images

What do you call a very old stego file? A stegosaurus

next video : how to hide cat in your files

Thanks youtube recommendation .

A long time ago someone from my discord server posted an image that said if you changed the .png to a .mp3 it would play music, being skeptical I did what the picture had said and to my surprise it had worked flawlessly. I am wondering how they were able to combine both a png and mp3 together as I am unable to find any information about changing the file extension to attach an mp3 to a png

What I liked: The video. What I didn't like: My new-found paranoia.

*Sending: cat.png* 2.67 Gb

time to start checking all the images i have downloaded for hidden stuff

Is this logan paul but worth watching?

Nice way to hide images inside images

I think it's safe to assume you eat most of your meals at your desk :p

There is a way to hide larger files (up to like 20 MB or something) in audio as long as the audio is stored in lossless codec (ape or flac) format... The software called deepsound and it's pretty cool If you want to do image steganography on Windows you can use the Java based application called openstego

great video, although a sidenote - this doesn't have to be Kali linux at all. you can do it on any distro and as a matter of fact can be easily done on a RPI. just apt install steghide. this is also a great way of hiding stuff that you (I) always forget in things like public images just to be able to retrieve them later at some point when you forget them. Nobody would suspect a random picture on your insta to contain vital information

Think of all the illegal lego building techniques you could hide in this image

@11:35 there is two very noticeable things about the image than just the file size. It's pretty easy to see the image colors are degraded when compared together. also I just want to point out a couple other things here, Steghide is the backend, but there's also Stegosuite which gives you a GUI frontend of Steghide which makes it all the more easier for people who aren't use to using command line stuff. It is however limited to using certain images when hiding files such as BMP, GIF, PNG, and JPEG. -- Also one other tool to the Steganography set of tools is Stegsnow, stegsnow is a whitespace steganography program which appends hidden secret messages in text files in the form of tabs and spaces to the end of a file.

I just ran across your channel. All the stuff is so interesting to hear about, and you explain everything well so that even I can understand it Subscribed.

\*hides entire hentai collection*

i hid a bitcoin wallet address in a doom map 2 years ago :P the one place no one would ever suspect. or be able to figure out even if they did, because even if you had the map it was pretty much impossible to figure out because it was hidden in the X coordinates of vertexes along a specific wall and you needed a separate lookup table to make sense of it (that was hidden in a texture i used in the map), even if you knew that the message was there in the first place, which you wouldn't because there's literally no signs of it. then i realized that wallet wasn't worth that much security and just dropped it. i wasted so much time doing that, lol. also the wallet is empty now.

Had to go over steganography in my information security class and tbh it was my favorite chapter

Awesome video. Lays it all out, shows how it did it, no fluff

Im gonna use this trick to smuggle memes into EU once article 13 passes

I actually did find this very interesting! Great job on the video man! I learned something new!

The encryption method of the image is quite high and perfect if you want to "conveniently" transfer files between pcs and have programming fun at the same time!

awesome video! This channel is very underrated

10:03 was really your encrypted message which you just showed on your tutorial video. Shell game my friends!

Love you bro!! You are the best! Trying to be a RU-vidr like you bro!!

not directly embedding but you can "hide" data "in" images using the dos copy command in cmd. creates a non-compressed zip with the image as its front disguise. navigate to folder then copy /b [file1.jpg] + [file2.random] [output].jpg

I remember in the XP days that my printer software was always running, I found that it was always sending log files, I opened one with text editor and found a bunch of code "ramdom characters"but then I found names of software installed on the computer and websites I had visited!

There is a way to detect it with the first example if you have the image side by side. The colours on the steg'd image are a bit more faded (notice box and the colours on the steg'd image compared to the ref image) but again, people wont know if it is steg'd if they dont have the ref image

As far as this goes... You could have hide your entire diary on the very fotograms of this video... An a testament on its sound file.. quite clever! Jajajq love the video, you rock!!! thank you so much!

You can hide files into images using command prompt and winrar as well. If you open the image with winrar, it will show the other files

You are the best instructor ever

Really interesting video :) thanx for sharing ^^

Easy to find if an image has any data. Use Strings, binwalk, xxd or stegsolve

A intelligent boy! good work.

This will come in handy

11:44 If you look closely at the two images, the colour in the image on the right has a slightly different registration to the one on the left: it's so very slightly lighter. I guess this is as a result of the embedding process.

Would there be a way to do this with a video file? Store a little bit of a large file in each frame if the video???

Around 14:25 presenter suggests data is hidden in areas where image has lots of details, like in cat's whiskers, but that's not necessarily the case as JPG images are typically compressed when saved. Different compression levels mean different changes to images. So for example when image A is saved with milder compression than image B, then that causes differences.

An easier way to do this without needing a VM or Knowledge in Linux or Kali is to simply download the compression tool called 7z. Bellow are the steps: 1) The first thing you will need to do is create the file you want to hide in your image file. This can be done from 7z. Create a compressed file with all your files inside (Password optional). 2) Use the windows command prompt and Type "CD FolderLocation" 3) Use the windows command prompt and Type "COPY /B Image.jpg + HideMe.7z Output.Jpg" And there you go, Output.Jpg now contains your hidden files. If you want to extract these files you can use the 7z.exe command line. Bellow are the steps: 1) Open Notepad 2) Type the following into the NotePad --> C:\Path\7z.exe e -y Output.Jpg -o"%~dp0" -p"Password" 3) Save as an .bat and run. And there we have it. A much more simple and easier way to do exactly what was done in the video without a VM or Linux.

"somewhat interesting"? Absolutely! Great job

Nice, this is cool

Thanks!

legitimate question, can you embed an already embedded picture into the "vessel" file, and if so how many times can you do this before the original image just becomes unrecognizable? For example, take a picture embed a copy of the picture into itself, then embed that into a copy of the original and so on and so forth.

Thanks

Could you use a software to view the metadata and if so would that reveal any changes to the picture file?

Quite an interesting video. I stumbled upon this while researching methods to share secret information. I find it really amazing that data can be embedded in images this way. So, if an original image is used and ONLY shared between those with agreed access, would this method make unauthorized access to the secret data impossible?

Does the lighting of the image on the left seem more orange in colour on the box pre Steg ? 7.32 onwards

Very cool indeed. Hiding it in one of the channels is a good technique. I wonder if it would work for other formats and not just RGB - YBR or monochrome. Or if compressing it and decompressing will result in the same data

I have made a python script similar last years (for a personal project ). I could only hide text on the image by converting it to ascii and writing pixel by pixel the text ( if I encouter a 1 in the ascii then I rise the RGB value of a pixel by 1else i do nothing ). And to decript the message, the original image was needed in addition to the one with the message in it, by comparing them i could retrive the hidden text Hope that make sense

can we get a video about parrotOS and the differences it has with kali?

What happens if you crop the picture? Wil you be able decrypt the remaining info in the embedded file? And BTW there is a Channel interfering your sound Channel playing annoying Music.

Is there a way to decrypt these files if someone put it in your device and you aren’t aware of the pass phrases?

You can do something similar in windows: you have a.jpg and b.rar, you run: "copy /b a.jpg + b.rar c.jpg" and you got c.jpg which is a working image, but if you open it with an archive program like winrar you can see files in it. This is the binary copy It isn't encrypted it just copy them to one file.

We had a CTF contest in a summer camp. There was a flag hidden like this.

Hi, 2 little questions : can we transfer this image to an externe hard drive and will It still have the hidden file in it ? And is it possible to make all of this on macOS ?

some files like someone else said, are available to the public and thus you can compare it not only but the size but if ur like me, can see minor changes. EG: if you look at the side of the head then there is a minor little difference in color. idk if anyone else can see this but I can. I looked hard but it was easy. Edit: just saw later in the video but ehh who really cared

you can also use OutGuess

I see color difference in the images. which may indicate compression

Just put al, the stuff into a folder, then zip it and rename the extension so your pc thinks it is another file type. Try renaming it to a dll file and make the whole file name sound convincingly like a system file. Then send the person a video game and put your secret file in the game folder. Only they will know how to open it. This is more effective if you zip it to 7z or another format in case someone already knows this trick

I did this on my channel a few years ago :)

Imagine just inserting someone's USB drive and all there is is cat photos

Keep going bro

When you first made the image and said 'and there's nothing discernable between the original and the new, except for the file size' Am I the only one who noticed a slight difference in darkness on the left side of the image? Specifically the cats shadow, and the cardboard coloring, or am I tripping?

hmmmm but, what if you edit that picture in photoshop after you embed a file in it ? can you do a video with this?

What is the name of this background music? I did find it before, but it has vocals in it. I'd love to have this instrumental version only, sounds really fun in my opinion. :)

Dam, you look like the creator of the oasis in ready player one. I can never look at you the same way

I'm middle aged, and my inbox is indeed full of cat pics!

How do I compare the audio file?

Hi, what if you don't know the passphrase of the image file, how can you decrypt the file?

Great, now I have to stop and look a every image in hopes of finding some nuclear launch codes.

Is it possible to hide a remote access tool in Image.and the tool will be automatically execute by clicking the image

You can use cmd copy command on windows

Is tgere windows sw? Is there desktop sw to compare images and histograms ?

Hello, what if the file that be hidden in the image is .exe or .apk file, does it can run while opening the image?

I remember doing this with the copy command in dos

The ketchup lol

Hey it's showing UNABLE TO LOCATE PACKAGE STEGHIDE what should I do

Tomato Ketchup and Habanero sauce - Kudos

steghide: could not extract any data with that passphrase! even though i typed the passphrase correctly the picture was sent already and i just downloaded it and tried to extract but this came out

Aww dude!!! You should of uploaded a steg image to imgur and put the link in the description D:

I don't have graphic Kali, only text. Can I still do that?

7:33 is it me or does the original one have brighter orange colors, it's like the output one has lowered saturation

i was doing this on win98se back in the day course many sites today optimize images which will zap the hidden stuff.

You can create the same in windows if you create an empty zip file and random image and then type "copy -b image.jpg + zip.zip = normal.jpg" than you can just open it in zip manager like 7zip winrar and more.

its been done in late 90's and a long time ago we have all those files

hello, really liked this video but i would like to ask you something...i have been struggling with a nfc tag, so i have to find it's password but in order to do that i have to scan it from my pc but i dont have a nfc reader so i thought i could use my phone as a reader...the problem is that im stuck...i just dont know what to do now, i have installed everything but i dont know how to connect the pc to the phone as in a guide i found on internet, hope you will read this massage thank you and if you want the link to the guide just tell me.👍🏻

*Eyyyy Gandalf! I found him.*

I think hiding an encrypted file (or file container) would be the way to go. That way it isn't obvious and very well hidden too.

Now I can hide my 2GB homework folder

Can i use This to infect a pictures with a backdoor?

If i dont know txt file. What can i extract image file??

this tool would be great if it was ported to android with a gui or using termux's apt repo

What if I hid an encrypted file in an image and then publish it publicly?

Aw man, I stepped on a stego.
