Trace a Hacker

Want to know if someone is hacking your computer? Command Prompt can help you find if someone you don't know is connected to your computer stealing private data. Just execute netstat -a and the command prompt will return a list of computers that your computer is connected to. In the results returned, Proto column gives the type of data transmission taking place (TCP or UDP) , Local address column gives the port with which your computer is connected to an external computer and the Foreign Address column gives the external computer you are connected to along with the port being used for the connection. State gives the state of the connection (whether a connection is actually established, or waiting for transmission or is “Timed Out”).

TO stop stealing your Wifi connection

Command Prompt can let you know if someone is connected to your Local Area Connection and using it. Just follow the steps:- 
1) Open your browser and visit http://192.168.1.1 or http://192.168.0.1 depending on your router. 
2) Find the tab that mentions “Attached Devices” or something similar.
3) Find the computer name, IP address and MAC Address (sometimes called Physical Address or Hardware Address) of your computer using the previous trick.
4 )Compare it with those displayed by your router in Step 2. If you notice some strange devices, then your neighbour has been sneaking in on your internet connection and it is best to set a password.

Know your IP address, DNS Server's address and a lot more about your Internet Connection

Command Prompt can even let you know your IP address. Just type ipconfig/ all in the command prompt and press Enter. Along with your IP address and DNS servers, command prompt will also return a ton of information like your host name, primary DNS suffix, node type, whether IP Routing ,Wins Proxy, and DHCP are enabled, your network adapter's description, your physical (MAC) address etc . 

Shutdown Your Computer or a Remote PC via Command Prompt

Most of us shutdown our computers using the power button given in the Start menu. Some of us use the physical power button on our machines. Very few people actually use other means of shutting down a computer and even less is the number of people who use the command prompt to shutdown a computer.

A reason for this is that most of us don't know that the command prompt can be used to not only shutdown, restart or log off our computer instantly but also to shutdown a remote computer provided you have administrative access. It can also be used to hibernate a computer and give a comment containing the reason for shutdown. This post will show you how to do all this.


Required
A computer running Windows (XP, Vista, 7 or 8) with the command prompt working perfectly, i.e. not disabled by a virus.

Initial Steps 
1) Press Windows Key + R.
2) Enter CMD and press Enter.

This will start the command prompt. Follow the instructions below depending on what you want to do.

Shutdown Local Machine (Your Computer)
Type "shutdown -s" without the quotes in the command prompt and press Enter. Shutdown is the command being executed and the switch -s tells the computer to shutdown.

Restart your Local Computer 
Type "shutdown -r" in the command prompt and press Enter. In this case, the command switch -r is telling the computer to restart after shutdown.

Log Off the Current User
Type "shutdown -l" in the command prompt and press Enter. The -l command switch tells the computer to log off.

Shutdown a Remote Computer
Type "shutdown -s -m \\name of the computer" in the command prompt and press Enter. Replace \\name of the computer with the actual name of the remote computer you are trying to shutdown. As mentioned earlier, you must have administrative access to the computer you are trying to shutdown. To know if you have administrative access, press Windows key + R and then type the name of the computer and press Enter.

Note: If you don't remember the name of the remote computer, you can look for it by opening a list of all the computers you are connected to by executing "net view" in command prompt.

If you can connect to the computer, you will be asked to login with your username and password. Upon entering them, a window will display the list of all the directories available to you. This should help you know whether you can or cannot shutdown the remote computer.

Hibernate a Local Computer
Type in "Rundll32.exe Powrprof.dll,SetSuspendState" without the quotes and press Enter. Your computer should hibernate, if it does not, then you must enable hibernation to do this.

Shutdown your or a remote computer after a specific time
Type "shutdown -s -t 60" to shutdown your computer after 60 seconds. Upon executing this, a countdown timer displaying a warning message will be shown. This command uses the -t command switch followed by a variable (which is 60 in this case) which represents the number of seconds after which the computer will shutdown.

Display a Message containing the reason for shutdown
Type shutdown -s  -t 500 -c "I am tired. I don't want to work anymore." (with the quotes) in the Command Prompt and press Enter. The -c switch is used in the code to give the reason for shutting down and what is followed in quotes will be displayed in the dialog box as the reason. This can be used to display all sorts of funny messages. One example :-

Skynet has become self aware. John Connor did not stop me. You can not use your PC anymore.

Stop a System Shutdown
Type "shutdown -a" and press Enter. This will stop the system from shutting down if the countdown to shut down has not reached 0.

Make Undeletable, Unrenamable Folders

Have you ever wondered how you can make a folder which neither can be deleted nor be renamed. Well, if you have, then you have come to the right place. With this trick, you will be able to create folders in Windows which cannot be renamed or deleted.

Basic Concept
The basic concept behind this trick is the use of Keywords. Keywords are reserved words in any programming language that cannot be used as names of variables. Windows also uses certain keywords in its programming. Some of them are con, aux, lpt1, lpt2, lpt3, lpt4, lpt5, lpt6, lpt7, lpt8 and lpt9.

A Test
To test this concept, make a new folder in Windows and try to give it a name same as any keyword suggested above.

Result
Windows will not rename your folder to any of the keyword given above.

Trick
So the question arises, how can we make a folder with a keyword as its name? The solution to this problem is included in Windows itself. As we know that Windows has evolved from D.O.S.(Disk Operating System), its commands can be used in Windows. You can use D.O.S. Programming in Windows to create a folder with a keyword as its name using the steps given below:-

1. Click on Start.
2. Click on Run. Type in "cmd" without quotes.
3. In the Command Prompt Window that opens, type the name of the drive you wish to create your folder in the format <drive-name>: and press Enter. e.g. If you wish to create the undeletable folder in D drive, type "D:" without the quotes. Note that the folder cannot be created in the root of C:/ drive (if C: is your system drive).
4. Type this command- "md con\" or "md lpt1\" without the quotes and press Enter. You can choose any of the keywords given above as the name of your folder.

Now Windows will create an undeletable, unrenamable folder in the drive you entered in Step 3. However the folder can be renamed to another keyword using Windows Explorer.

Deleting the Folder 

Although it is not possible to manually delete the folder, you can delete the folder by typing "rd con\" or "rd lpt1\" in Step 4 instead of "md con\" or "md lpt1\". 

Windows Compatibility: This works on Windows XP, Windows Vista, Windows 7 and Windows 8.

Try it yourself to create one such folder which can neither be deleted nor be renamed.

1) Download NetBus 2.0 Pro. from here -  NB2ProBeta.zip

2) Extract and install properly on your system.

3) After installation you will find the two shortcuts in the NetBus installation directory.

	This is to be executed on victim's system.
	This is to be executed on your system.

4) By Executing the 'NetBus Server' (on victim's computer), you will be greeted by a window as shown 

                                                     

in figure (left). Click on 'Settings' button.
Here you can configure server settings such as port no, password, visibility, auto/manual start, etc. as shown in figure (right). 

         

               

                      

       

Click on 'OK' button to finish NetBus Server settings.
Then close the NetBus Server window.

5) By executing 'NetBus' (i.e. client)(on your system), you will be greeted by a window as shown below

6) To add a new host go to the menu 'Host' and then click 'New'. This is as shown in figure (left).
Here you should enter the proper Destination(e.g. 'My Computer'), IP Address(eg. 72.232.50.186), TCP Port(by default 20034), Username/Password(exactly same as that of 'NetBus Server') for target computer

Click on 'OK' to finish the addition of new host.

7) Now you are ready to connect with target(victim's) computer.
To do so, select the host from main window then go to 'Host' menu and then click 'Connect'.
