Very clever!

I thought so too!
I was going to put up a similar post a while ago but it involved manually editing a hex code with hexedit but I found this way instead!

thanks for visiting

Yup its really quite cool. Because I’m chinese I’ll tell you that it is really similar to what they did in the past.

They hid messages in mooncakes (its a kind of pastry) during the war in the past.

The two methods basically have the same principle. With the jpg files, you wouldn’t do anything more but view them if the file was not intended for you. With mooncakes, you definitely wouldn’t be opening them up if you were not the intended recipient of it so only the recipient would eat it and find the message.

A great observation. It never occured to me that WinRAR checks for archive header anywhere within the file instead of usual beginning of file

Jalajj’s last blog post..Drive Slowly : Google Ahead

yes, it’s pretty good. there is another way of hiding a zip file within another file but I can’t seem to find where I saw it anywhere! I’ll keep searching and put up the details here if I find it seeing as how many people have come here for this one.

thanks for visiting!

I just happened to see your wp plugin post. I have added your RSS feed so would be reading you regularly.

Have you ever worked on RPC for posting to wordpress… I need a simple page that takes title, post content and Categories and posts it to a wordpress blog using RPC… checked the RPC standards pages but could not get any meaningful out of it.

Jalaj’s last blog post..Drive Slowly : Google Ahead

I’ve never heard of RPC but i’ll have a search around and see what it is.

thanks for subscribing to my feed, I did the same with yours! although, I had to search around a bit for a link, in the end I just added /feed/ to your site name and got it that way

good ashwin bashing at your blog!

wow that is one nice trick, i could very well use that with my other site http://ebooks-tutorials-magz.blogspot.com where i am sharing ebooks free and can be downloaded at free file hosting sites, this could save me from having a deleted links and reuploading again thanks man!

Very cool - I never knew you could do this.

Stop publicizing Winrar. It’s proprietary software.

You can do the same with 7zip files, and 7zip is open source and there’s a portable version of it for Windows, so you can do it (pretty much) anywhere - I know I do.

Also, another tip for you.

Go in the command prompt and type [code] ATTRIB +S +H name_of_a_folder [/code]. The folder will DISAPPEAR, and you won’t be able to find it even if you change the settings to “show hidden files and folders”. There is an option that enables you to see them, but nobody uses it (show protected system files).

To enter the hidden folder, just type its name on the address bar. To undo this, type [code] ATTRIB -S -H name_of_a_folder [/code].

This won’t have any relevant effect outside Windows (dunno about Macs, but it’s useless on Linux).

Have a good time hiding your Pr0n and your Captain Planets.

“thanks for your comments but why should I stop publicizing winrar? this post is only a tip for putting files in a jpeg. no big deal.”

As said before, it is also possible with other apps, not just WinRAR. that’s why.

Have you gotten this to work on vista? Doesn’t seem to work for me - the two copy together just fine, and the image is still viewable, but winrar thinks the archive is broken. Tried it about four times with different files to no avail.

Sir why would one need to hide the .rar? Sir, would it be possible: .jpeg has a hidden .rar that has a trojan?

Can I use the .jpeg to hide a .rar that contains a trojan….

“ok, so it’s not an anti-winrar mission you’re on then.. just a pro ‘other’ compressional programs one?”

- More like, pro-open-source.

” “give winzip a chance!” ra ra ra! ”

- lol Doesn’t seem to work with .zip files, but it does with 7z.

“this post is only a tip for putting files in a jpeg.”

- Nothing wrong there ~but it also works with other file types (.png .gif, etc…).

“Have you gotten this to work on vista?”

Haven’t tried either, but I’d most likely recommend you to upgrade to Windows Xp ~if you won’t make the switch for Ubuntu, that is.

“don’t know about pr0n though, I’m pretty sure there’s none here and no mention of it anywhere in my posts.”

Inserted for comedic purposes (aka lulz), no harm intended.
I’m perfectly aware there’s more usefulness for the System+Hidden attributes than that. i.e. I have a USB flash pen drive loaded with portable apps, a custom autorun.inf file and .ico logo. I made a hidden /System folder with everything and I use another application to quickly launch stuff: Pstart http://pegtop.net/start/ (still looking for a good non-proprietary alternative). No, I don’t like PortableApps.com Suite, even tough it’s Open Source.

again @ marcus: btw, do you know that new ‘cool’ feature of Vista, where you can search the Start menu just by clicking the Windows key? Pretty useful, hum? ~I’ve been doing it for ages on Xp ;P http://www.launchy.net (open source).

cheers

Nice tip - I have Vista and it works fine..

One note that might be helpful to some - Windows provides greater flexibility when naming a file i.e., 2008 Disneyland.jpg (no space between 2008 and Disneyland)- but I believe DOS uses the old naming convention where spaces are not allowed - thus will return a Syntax error if the files you wish to combine/hide/rename have spaces in them.

So - prior to using your great tip - merely rename them in Windows if they have spaces - and all is well.
Thanks again..
Nightcheck

@Nightcheck

PROTIP: instead of

: copy 2008 Disneyland.jpg randomfoldername:

try

: copy “2008 Disneylang.jpg” randomfoldername :

slam! problem solved.

About Vista - I’ll never accept intrusive system-wide forced DRM. I won’t get it until there’s a properly hacked version out there (no DRM, no ‘Security’ popups everywhere, etc…).

Don’t get me wrong, tough - it’s not about IRL monies. The college I go to has a protocol with Microsoft that sums up to free Micro$oft Software for evry1. (Free Windows 2000-to-Vista and MS Office licenses, SDKs, MS database servers, you name it…)

By mentioning Vista, I definitely wasn’t intending to advocate it. If Linux ever catches up to the big two in application support and otherwise (read, I’m a computer geek, but between school and work I don’t have enough time to be THAT much of a computer geek) I’d love to keep it around, but until then, I have a macbook for work, and just bought a little desktop system with vista so that I don’t offend and incur the wrath of the great lord Bill of Microsoftia.

Upgrading to XP would require doing things… things I said I would never do again…

Great Tip!

This old trick we use at my office to hide MP3 and AVIs from security scans on my company network (My company considers mp3 a security threat… no comments). Since the scan robots only check for the first file header they found the trick is to merge them in the correct order, JPG first and then the MP3 or AVI. If you do it backwards it doesn’t work.

Wow, that could do some unwanted damage… Nice find though.

Hey Andy - I believe that’s the case. A lot many people are against Vista but I think that’s more cos ppl are content with XP!

Tried this out using 7zip, worked fine. Do you know if there is a way to search for images that have these hidden archives?

Nice tip!!!

nice tip!

Matt @ 41 -
MP3check is a cross-platform command line utility which lets you check arbitrary files for MP3 content, including concatenated files using these command prompt options:
mp3check -c -N –no-summary –reject=mp3 *.*
(Start Accessories Command Prompt)

In notepad, you can create a batch file (mpchk.bat) on the desktop, and drop suspect file(s) on it:
mp3check -c -N –no-summary –reject=mp3 %1
pause

To install mp3check, just unzip MP3CHECK.EXE(and CYGWIN1.DLL if you don’t have Cygwin installed) into your c:\windows\system32 directory (or wherever you put %SystemRoot%\system32). Get it here: jo.ath.cx/soft/mp3check/

Very useful information for me. Thanks.

This is a pretty neat way to send a hidden message. If you find the Zip IN a Zip deal thet would be even better. I’ll check back. Fred

Hello There,

Just thought I’d say that was very cool thanks for the tip.

This is just brilliant!
I don’t have a real need for it, but it is one of those cool nerdy tips that are just fun to know!

@Andy Bailey
Andy I created such an embedded jpeg using RAR, then analysed that file using Forensic Tool Kit(FTK) analyzer. But I couldnt find any change in the header of original jpeg and jpeg created after.
Do u have any idea about how this trick really works, i mean behind the scenes

@ Andy Bialey:
THnx for ur reply. but jus in case u happen to find something more on how this works dont forget to post it [:)], n i’ll do the same.

very interesting..
Can send hidden stuff to friends without other people suspecting anything..

Thanks

So could this help in uploading a “jpeg” to a free image hosting site and then download the zip instead? They usually cap the file size @ 2MB or so so it won’t help too much but still a cool idea.

Neat trick. Thanks for sharing it. I also love the drop down welcoming me as a visitor from Google.

Cool little trick… something I can take advantage of.

That’s pretty cool I’ll remember this and use it when i need to send sensitive information in a not-so-obvious way.

thats a pretty good idea. Is this applied to other file type too? can I mix other file (let say mp3 file) in image?
