Secretly Hide Any File Inside JPG Image File

[MicroTechno]

Few months ago , USA Today story claimed that al-Qaeda operatives were sending out encrypted messages by hiding them inside digital photographs [jpg files] on eBay.

While the claim was never proved, it is very easy to hide [or embed] any other file[s] inside a JPEG image. You can place video clips, pdf, mp3, Office documents, zipped files, webpage or any other file format inside a JPEG image.

And when a suspecting user [read CIA, FBI] tries to open that jpeg file [with concealed information] in either a photo editing software or as a thumbnail inside Windows Explorer, it would be tough to make out if this camouflaged jpg file is different from any standard jpg image.

Let's say you want to hide a confidential PDF document from the tax investigation officers. What you can do is convert that file into a regular jpg image so even if anyone double-clicks this file, all he will see is a preview of the image and nothing else. And when you want to work on the actual PDF, just rename the extension from jpg to pdf.

Here's the full trick:

Step 1: You will need two files - the file you want to hide and one jpg image - it can be of any size or dimensions. [If you want to hide multiple files in one jpeg image, just zip them into one file]

Step 2: Copy the above two files to the C: folder and open the command prompt window.

Step 3: Move to the c: root by typing cd \ [if the files are in another folder, you'll have to change the prompt to that folder]

Step 4: The most important step - type the following command:

copy /b myimage.jpg + filetohide.pdf my_new_image.jpg


To recover the original PDF file, just rename my_new_image.jpg to filename.pdf.

Here we illustrated with an pdf file as that works with simple renaming. If you want to apply this technique to other file formats like XLS, DOC, PPT, AVI, WMV, WAV, SWF, etc, you may have to first compress them in RAR format before executing the copy /b DOS command.

To restore the original file, rename the .jpg file to .rar and extract it using 7-zip or Winrar.

@Kovai

there is a lot of difference between your trick and this one...

in this trick the resultant file will behave like a normal jpg... you can preview the file and also open it like a normal jpg...

@thread starter

you missed one step... to make this thing work properly....

suppose you want to hide 1.mp3 inside a jpg file name abc.jpg...

you need to perform following actions...

Quote:1. Copy both files to same directory e.g. c:/test
2. zip 1.mp3 into a rar file with winrar or other software say you have comverted to 1.rar
3. Open Command Prompt
4. Goto c:\test
5. type copy /b abc.jpg + 1.rar new.jpg
6. thats it , you are done... you will have new.jpg in same folder... you can use it as a normal jpg file...

to extract original file/s

Quote:1. Rename new.jpg to new.rar
2. Extract with winrar or any other software
3. You will get your 1.mp3 file

similarly you can do it for multiple files... just need to add all those in rar file...

One Doubt , How there will be a preview ?

[viv_thegame]

bro... just try it...

actually what this trick does is, it appends rar file to jpg file...

as jpg data is there... it still can be parsed...:hello:
