Πώς να κρύψει τα αρχεία στις εικόνες JPEG

Ταχυδρομημένος στις 16 Απριλίου 2008 στις 5:34 AM

Εάν κοιτάζετε αρχεία δορών στο σκληρό δίσκο PC σας, μπορεί να είχατε διαβάσει για τους τρόπους να κρυπτογραφηθούν οι φάκελλοι ή να αλλαχτούν οι ιδιότητες σε ένα αρχείο έτσι ώστε δεν μπορούν να προσεγγιστούν με να ανοίξουν τα μάτια. Εντούτοις, πολλοί χρόνοι που κρύβουν τα αρχεία ή τους φακέλλους με εκείνο τον τρόπο απαιτούν ότι εγκαθιστάτε κάποιο είδος του λογισμικού στον υπολογιστή σας, ο οποίος θα μπορούσε έπειτα να επισημανθεί από κάποιο άλλο.

Έχω γράψει πραγματικά κάμποσα άρθρα σχετικά με τον τρόπο με τον οποίο μπορείτε να κρύψετε τα αρχεία και τους φακέλλους στα παράθυρα XP και Vista πριν, αλλά εδώ πρόκειται να σας παρουσιάσω νέο τρόπο να κρύψω τα αρχεία που είναι πολύ αντίθετος-διαισθητικός και επομένως αρκετά ασφαλής! Χρησιμοποιώντας ένα απλό τέχνασμα στα παράθυρα, μπορείτε πραγματικά κρύψτε ένα αρχείο μέσα του αρχείου εικόνων JPG!

Μπορείτε πραγματικά να κρύψετε οποιοδήποτε τύπο αρχείου μέσα ενός αρχείου εικόνας, συμπεριλαμβανομένου txt, exe, mp3, του avi, ή ο, τιδήποτε άλλου. Όχι μόνο ότι, μπορείτε πραγματικά να αποθηκεύσετε πολλά αρχεία μέσα του ενιαίου αρχείου JPG, όχι μόνο ένα! Αυτό μπορεί να έρθει πολύ σε πρακτικό εάν πρέπει να κρύψετε τα αρχεία και δεν θέλει να ενοχλήσει με την κρυπτογράφηση και όλη αυτήν την άλλη τεχνική ουσία.

Αρχείο δορών στην εικόνα

Προκειμένου να ολοκληρωθεί αυτός ο στόχος, θα πρέπει να εγκαταστήσετε είτε WinZip είτε WinRAR στον υπολογιστή σας. Μπορείτε να μεταφορτώσετε καθενός αυτών των δύο από το Διαδίκτυο και να τα χρησιμοποιήσετε χωρίς να πρέπει να πληρωθεί τίποτα. Εδώ είναι τα βήματα για τη δημιουργία του σας που κρύβεται stash:

Δημιουργήστε έναν φάκελλο στο σκληρό δίσκο σας, δηλ. C:\Test και βαλμένος σε όλα τα αρχεία που θέλετε να κρύψετε σε εκείνο τον φάκελλο. Επίσης, τοποθετήστε την εικόνα στην οποία θα χρησιμοποιείτε για να κρύψετε τα αρχεία.

Τώρα επιλέξτε όλα τα αρχεία που θέλετε να κρύψετε, σωστός-κρότος σε τους, και να επιλέξετε την επιλογή να τους προσθέσετε στο α συμπιεσμένο ZIP ή RAR αρχείο. Μόνο επιλέξτε τα αρχεία που θέλετε να κρύψετε, όχι η εικόνα. Όνομα αυτό οποιου δήποτε θέλετε, ι, ε. «Hidden.rar».

Τώρα πρέπει να έχετε έναν φάκελλο που φαίνεται κάτι παρεμφερές με τα αρχεία, μια εικόνα JPG, και ένα συμπιεσμένο αρχείο:

Τώρα εδώ είναι το μέρος διασκέδασης! Χτυπήστε επάνω Έναρξη, και χτυπήστε έπειτα επάνω Τρέξιμο. Τύπος «CMD» χωρίς τα αποσπάσματα και τον Τύπο Εισάγετε. Πρέπει τώρα να δείτε το γρήγορο παράθυρο εντολής ανοικτό. Τύπος «CD \» για να φτάσει στον κατάλογο ρίζας. Κατόπιν τύπος CD και το όνομα καταλόγου που δημιουργήσατε, δηλ. “Δοκιμή του CD“.

Τώρα τύπος στην ακόλουθη γραμμή: ; αντίγραφο /b DSC06578.JPG + Hidden.rar DSC06578.jpg; και Τύπος Εισάγετε. Μην χρησιμοποιήστε τα αποσπάσματα. Πρέπει να πάρετε μια απάντηση όπως κάτωθι:

Just make sure that you check the file extension on the compressed file, whether it is .ZIP or .RAR as you have to type out the entire file name with extension in the command. I have heard that some people say that they have had problems doing this with a .ZIP extension, so if that doesn’t work, make sure to compress to a .RAR file.

And that’s it! The picture file will have been updated with the compressed archive inside! You can actually check the file size of the picture and see that it has increased by the same amount as the size of the archive.

You can access your hidden file in two ways. Firstly, simply change the extension to .RAR and open the file using WinRAR. Secondly, you can just right-click on the JPG image and choose Open With and then scroll down to WinRAR. Either way, you’ll see your hidden files show up that you can then extract out.

That’s it! That is all it takes to hide files inside JPG picture files! It’s a great way simply because not many people know it’s possible and no one even thinks about a picture as having to the ability to “hide” files. Enjoy!

There in fact is a problem with Winzip on reopening the jpeg file - so Winzip doesn’t work.

I tried 7-zip and it works - both zip and unzip. Thanx for this simple DOS tip.

akishore said on : April 16th, 2008 at 9:48 pm

Hi Jimmy, thanks for confirming. I tried and it had some issues, but I thought it could be a problem on my side. Guess not! Good to know that 7-zip works also..anyone else try a different zip program, then let us know if it works.

po3tree said on : April 17th, 2008 at 3:09 pm

Neat trick. Worked just fine for me using using WinZip. I was able to open the jpg archive using the “Open With” function. Thanks.

Jonoro said on : May 6th, 2008 at 9:39 pm

Hey, Jimmy, how exactly did you get this to work with 7-zip? I’ve tried and tried and haven’t been able to split the files. My process(es) have been 1) change extension to .7z or .zip (tried both ways) to which I got the “invalid archive” error prompt 2) open with gives the same.

Any suggestions on that one?

Puhazh said on : June 20th, 2008 at 2:36 am

It will work fine with WinRAR

xumxum said on : July 6th, 2008 at 2:08 pm

works great, love the idea. tried with winzip. Don’t forget the /b switch in the copy cmd, without it I got a can’t open zip file, with it works like charm.

Me said on : July 6th, 2008 at 3:00 pm

If you are using a NTFS file system you should look at Alternate Data Streams also.. http://www.heysoft.de/nt/ntfs-ads.htm

Juan said on : July 7th, 2008 at 2:05 am

Something like this for Linux? thanks.

Peter said on : July 7th, 2008 at 10:30 am

@xumxum
The reason it doesn’t work without the /b is because otherwise it is just the regular copy command. /b signifies creating a new file whose contents are those of the two (or more) combined.

@Juan
This is actually just a concatenation of two files.

Linux has a command cat to do just that:

$> cat f1 f2 > f3

I assume the reason this works is because the JPEG ends before the RAR starts:

The file contents are something along the lines of:

JPEG header
JPEG data
JPEG end
+
RAR header
RAR data
RAR end

The graphics program reads until the JPEG ends, and the RAR program searches for the RAR header and reads from there. Whether or not the de-compressor searches for the header (and doesn’t just start at the beginning) determines whether or not the file can be read.

I may be wrong though.

L7D said on : July 11th, 2008 at 2:12 pm

Always new that was possible… I never knew how, i just had to Un-encrpt (?) a file because there was a virus encrypted the same exact way to an installation file. devils.

no_one said on : August 1st, 2008 at 8:40 pm

@Peter
I think its
JPEG header
JPEG data
JPEG end
+
RAR end
RAR data
RAR header

Great tip BTW. Works great with 7-zip

Adrian Leslie said on : August 4th, 2008 at 11:15 pm

If anyone makes changes to the .jpg file using MSPaint, anything you attach to the end of the .jpg gets wiped out.

Adrian Leslie said on : August 6th, 2008 at 3:01 pm

However, I was wondering if .mpg, .wmv, and .avi files might show promise instead of .jpg files.

DigitalMind said on : August 20th, 2008 at 5:27 pm

I used this trick for a mystery GEO-CACHE in my area. (I hid the coordinates as a text file inside a jpg picture filled with numbers, people are looking for patterns in the image even though it has nothing to do with it!)

People are having a hard time decoding it.

Thanks!

astaswastika said on : August 24th, 2008 at 5:37 am

yeah this works man..
and this is very simple..

thanks!

Richard said on : August 28th, 2008 at 10:50 am

Pretty nice trick! Works with WinRAR.

Allan said on : October 23rd, 2008 at 2:18 pm

This is brilliant! Alternate Data Streams being put to awesome use!

kurt said on : October 28th, 2008 at 12:12 pm

I believe the /b is for binary, instead of text. That way it will use what is already there and not misinterpret unprintable chars or otherwise make changes.

Johnny_Tsunami said on : October 29th, 2008 at 2:44 pm

I just had a sick idea. Would this work as a way to share files online? You could upload the image to imageshack or whatevs, and others could dl the file.

Johnny_Tsunami said on : October 29th, 2008 at 2:51 pm

I can confirm that my technique does in fact work. Damn, I’m good.

Abhishek Sagar said on : October 31st, 2008 at 2:58 am

This even works with exe files. I tried

C:\>copy /b bang.jpg + pu.exe some.jpg
bang.jpg
pu.exe
1 file(s) copied.

now the only thing i am trying to do is figure out how to get the exe to run in the background when the jpeg file is accessed.

Mandeep` said on : November 4th, 2008 at 9:50 am

it wrks….

thnx a lot for sharing this…

Husla3x said on : November 5th, 2008 at 9:37 pm

Really cool tip. I would never have thought of that one. I guess all these other guys can’t say thanks and would have thought of it.

Angel said on : November 6th, 2008 at 5:45 am

Nice trick…

hmm said on : November 12th, 2008 at 2:56 am

there is a easier way to hide files if you dont want to put them inside a jpeg and only want to hide them.

1. just put the files in a rar archive and enable password and encrypted file names in advanced tab. so nobody can see even the names of the files you want to hide.
2. then you can change the extension (maybe to .dll and put it in windows/system32 folder nobody will find them)

Cforce said on : December 3rd, 2008 at 10:25 am

Has anyone successfully executed a .exe or .bat in the background while opening the picture?

This could be an awesome prank to hide a shutdown command inside the picture xD

xenomorf said on : December 6th, 2008 at 7:34 am

hello.. i can’t get it right. after i finished with the copy in cmd, i tried to open my picture but it won’t open. it ‘the is either an unknown format or damaged’.

help me..

xenomorf said on : December 6th, 2008 at 7:53 am

oowhh…sorry guys. my fault. it seems like larger size pictures don’t work. the first one i used was a picture with size 1600×1200. then i used a picture with size 600×900. the result is that I successfully combined and opened it using WinRar.

Thanks for the info.

zerosteve said on : December 18th, 2008 at 4:22 pm

If you use this technique in combination with encrypting and password protecting your archive then you can REALLY keep the files from other people. In winrar, if you dont have the password you cant even see the files. I LOVE this trick. Thanks!

Dacia said on : December 25th, 2008 at 9:04 pm

Excellent. Had to send my laptop for service last week and didn’t want sensitive files visible. Since I have tons of photos on the hard drive, it was very easy to hide all those files inside various JPGs. Brilliant!!!

john said on : January 2nd, 2009 at 12:19 pm

Dacia - It seems that Garry Glitter didn’t know about this trick.
If I wanted to hide pictures or anything else I would simply create a partition and hide it using Partition Magic.
As long as you don’t need to access it too often as it requires rebooting to view it.
If just a few pictures then use the old addage “the best place to hide an elephant is in a herd of elephants”. Simply alter the file extension to .dll and save it in the system directory.

kpl said on : January 19th, 2009 at 1:17 pm

Is there a way to divide those files back?

Richard Fdisk said on : February 15th, 2009 at 2:13 pm

Don’t forget to delete the originals after, or they’ll all still be in the folder together with the new file

DEADcamel said on : February 20th, 2009 at 8:23 am

Hi there, I can see only one problem with this method and that is that people usually become very suspicious of a jpeg file that is over 10 MB or so.

I think it would be better to edit the first few seconds out of an avi file which is, for example part of a tv series and make it look like it is just another episode.

This way you can have the file just about any size that you want with out raising suspicion as video files can easily be just about any size.

skillmachine said on : February 23rd, 2009 at 4:12 pm

I made a zip file using TugZip and it worked perfectly fine. p.s. i recommend tugzip
great program!
