How to Hide Files Inside JPEG GIF PNG Images

We discussed various methods for hiding files inside your computer. Methods include super secure Truecrypt which offers military level security and handy MyLockbox to lock any folder. But all these methods require installation of software on your PC which is obviously visible to others.

We are now going to talk about a unique method of hiding files that’s kinda sneaky and doesn’t require a third-party tool. This technique involves hiding  files inside JPEG, GIF or PNG images. Sounds cool, right? Lets see how it is done.

1. Create a folder in C drive. Give it a name, lets say Testfile. It’s location should be C:Testfile.

2. Now move all the files you want to hide inside this folder. Also move the image file in which you want to hide those files. Let’s say the files which I want to hide are FileA.txt and FileB.txt, and the image file is Image.jpg. We are taking .txt files as an example. You can take files of any format (.mp3, .doc, .divx, .flv etc.) and any number of files.

3. Select both the files you want to hide (FileA.txt and FileB.txt in this case), right click and select “Add to Archive”. Make sure that you’ve got a file compression tool like WinZip or ZipGenius, a cool free winzip alternative, installed.

4. Give it a name. I have given Compressed.rar. You can give it any name. 

5. Click on “Start” button. Type cmd in the search box. Press Enter. 

6. A command prompt window will open. 

7. Type cd  and press Enter to get to the root directory. 

8. Now type cd Testfile to enter in the newly created directory. 

9. Type copy /b Image.png + Compressed.rar Secretimage.png and press Enter. 

10. When you look up at Testfile folder, you will find a new image file called SecretImage.png. This image file is created in previous step with the help of command. Secretimage is just a name given to the new image. You could give any name and extension (like xyz.jpg or xyz.png).

Both the files FileA.txt and FileB.txt are hidden inside this image file. You can delete rest of the files now.

How to get our Files back from the image?

That’s easy too. Just right click on the image (SecretImage.png) and open it with Winrar/Winzip/ZipGenius. You will see both the hidden files. Extract them anywhere on your computer.

Update: From comments I came to know that few users are facing problem while opening image file in Winrar application. They can change the file extension of secret image file in which all the other files are hidden from .jpg to .RAR. (In the above case SecretImage.png to Secretimage.RAR) and then open it with the help of Winrar.

That’s about hiding confidential files in Images. A foolproof method to hide important files. Did you like this technique? Let us know in comments.

How to download Flash Files No Flash files in tmp

Firstly, we have our facebook page now, you will find a link to like this page in the right column, please like this page and keep yourself updated about new post(s) on Linux on Desktop.


First a disclaimer,it might be illegal to download flash file,it depends upon the websites TOS and I encourage you to go through them before attempting to download flash file, if it is illegal I will NOT recommend that you download flash file.

There are different ways to download flash file, there are plugins that you can install in firefox, there are scripts that allow you to do so, however,one of the better ways that I have used for years( at least more than a year) is copying FlashXXX files from /tmp and renaming them appropriately.

Whenever flash played any media file in the browser, it downloaded Flash file locally in /tmp and deleted it when you closed the page. This had many advantages, for instance if you find something interesting and have already watched it in browser, you do not have to download it again using some plugin, or for instance you could only play part of file by seeking it appropriately and the relevant section is only downloaded in /tmp.

However, I found after updating my system, I no longer had FlashXXX files stored in /tmp , I looked frantically on net to find out reasons for this and found that this has to do with Adobe Flash Player being updated, which no longer saves Files temporarily in /tmp. I further looked up different forums on the Internet and found Flash indeed saved file on the system locally, it was just bit more difficult to access them.

In this post I would try to demonstrate how to retrieve flash files stored locally in the system while it is being played in the web-browser when they are not saved in /tmp. This works with Mozilla Firefox, I havent tried this with other browsers, though it can work.

One approach to solve this problem would be to downgrade your flash to earlier version, but this is not recommended as updates fix many critical security vulnerabilities and further have performance improvements.

The key to finding flash is the fact that on POSIX based systems, or for instance GNU/Linux all the information about processes running on the system is stored in "/proc" directory were each running process is identified with Process ID and there is a directory corresponding to PID in /proc. Further, all the open File descriptors are maintained here i.e in a lyaman all the information about files opened by process is here.

So if we can find process ID corresponding to the instance of flash player and find the fd corresponding to opened flash file we can easily copy the file and this is the approach that is followed by this script ( I am not the original author of this script) :

Open your favorite text editor and copy the following script, and rename it to something like - findflash.sh

#!/usr/bin/env bash

for flashpid in $(pgrep -f flashplayer.so); do
cd "/proc/$flashpid/fd"
for video in $(file * | grep /tmp/Flash | sed s/(^[0-9]*).*/1/g); do
echo "/proc/$flashpid/fd/$video"
done
done

bash findflash.sh

We had opened a video in Firefox, then we executed findflash.sh script, which gave us file descriptors of opened flash video, we copied and renamed this to some meaningful file name and played it using mplayer.

How to Install APK Files on Android Device Emulator

In this tutorial you are to run any APK (Android application) file to your Android emulator. Assuming you already have the Emulator running  (if not sure how run the Android device emulator, refer to this http://blog.kerul.net/2011/09/android-emulator-to-run-your-apps.html) .

  Figure 1

Locate your adb.exe file in your Android SDK folder. In Windows environment normally your adb.exe is inside [Android-SDK-folder]/platform-tools/ . In my case, the adb.exe is in C:android-junoandroid-sdkplatform-tools (this is an example path to the adb.exe, may varies depending on your system). Find any APK file (for the purpose of this tutorial, I’ve prepare an APK file – download here http://bit.ly/peribahasa-apk ). After you’ve successfully downloaded the APK, put it inside your [Android-SDK-folder]/platform-tools/ as in Figure 2.

Figure 2

Now run the adb.exe through the command prompt, go to Start, and find cmd.

Figure 3

In the command line, go inside the platform-tools folder, as in the Figure 4. Execute command;

adb install Peribahasa.apk

C:Userskerul>cd

C:>cd android-juno

C:android-juno>cd android-sdk

C:android-junoandroid-sdk>cd platform-tools

C:android-junoandroid-sdkplatform-tools>adb install Peribahasa.apk

Figure 4

Later, the apps you just install will be in the emulator.
