Uninstalling Windows from Command Prompt

One option included in Windows XP is the ability to uninstall XP if you performed an upgrade from Windows 98, 98SE, or Windows Me.

The standard method of removing XP is achieved by booting into XP normally and uses the Add/Remove Programs tool in Control Panel.

If you are unable to start XP normally, the second option is to load XP in Safe Mode then use the same tool.

If you are unable to boot normally or boot into Safe Mode, XP can be removed by uninstalling from a Command Prompt.

The procedure is as follows:

Important Note: This procedure is available only if a successful image of the previous operating system was created during the XP upgrade.

Start the computer to Safe Mode with Command Prompt.

At the command prompt, type cd\, and then press ENTER.

Type cd\windows\system32, and then press ENTER.

Type osuninst.exe, and then press ENTER.

On screen instructions will guide you through the uninstall process to revert to the previous operating system.

This procedure can only be performed by users logged on as Administrator or a user with administrative rights.

Tracing or Routing a website using command prompt

Tracing or Routing a website using command prompt. This tip is only meant for educational purpose. I mainly use this trick to find out the hosting provider where a particular domain is hosted.
Follow the below steps:
1.   Start->Run->CMD  ie; open Command prompt
2.  Type the following command and press enter.

tracert www.websitename.com

in the above command, enter the desired website name.
Once you press enter, it tell you where a particular domain is hosted, Location, Country and some details of that domain.
Disclaimer: I am not responsible for this trick if this is used in a wrong way. I didn’t invent this method rather I myself found it somewhere else. Do not use this for Hacking purpose.

Block/Unblock sites without software

You can block or even unblock sites without any software. Just follow these steps and you can continue acessing the file.

•Go to Start >>> RUN .

•Type C:\WINDOWS\system32\drivers\etc
•Open the file "HOSTS" in a notepad

•Under "127.0.0.1 localhost" . Add IP Name
IP - IP of the site to be blocked
Name - Name of the site


Example :
127.0.0.1 localhost
210.210.19.82 www.sifymall.com

Sifymall is now unaccessable . For every site after that you want block , just add "1" to the last number in the internal ip (127.0.0.2) and then the add like before.

Hiding Files in JPEG

Well, did you know you could hide your files in a JPEG file? For this, you will only need to download WinRAR. You just need to have a little knowledge about Command Prompt and have WinRAR installed.

Ok, lets begin…
1. Gather all the files that you wish to hide in a folder anywhere in your PC (make it in C:\hidden – RECOMMENDED).

2. Now, add those files in a RAR archive (e.g. secret.rar). This file should also be in the same directory (C:\hidden).

3. Now, look for a simple JPEG picture file (e.g. logo.jpg). Copy/Paste that file also in C:\hidden.

4. Now, open Command Prompt (Go to Run and type ‘cmd‘). Make your working directory C:\hidden.

5. Now type: “COPY /b logo.jpg + secret.rar output.jpg” (without quotes) – Now, logo.jpg is the picture you want to show, secret.rar is the file to be hidden, and output.jpg is the file which contains both.

6. Now, after you have done this, you will see a file output.jpg in C:\hidden. Open it (double-click) and it will show the picture you wanted to show. Now try opening the same file with WinRAR, it will show the hidden archive…

This hack will allow you to hide files in jpegs’s without software installed

Netbios Hacking

THIS NETBIOS HACKING GUIDE WILL TELL YOU ABOUT HACKING REMOTE COMPUTER AND GAINING ACCESS TO IT’S HARD-DISK OR PRINTER.NETBIOS HACK IS THE EASIEST WAY TO BREAK INTO A REMOTE COMPUTER.




STEP-BY-STEP NETBIOS HACKING PROCEDURE



1.Open command prompt



2. In the command prompt use the “net view” command

( OR YOU CAN ALSO USE “NB Scanner” OPTION IN “IP-TOOLS” SOFTWARE BY ENTERING RANGE OF IP ADDRESSS.BY THIS METHOD YOU CAN SCAN NUMBER OF COMPUTERS AT A TIME).



Example: C:\>net view //219.64.55.112



The above is an example for operation using command prompt.”net view” is one of the netbios command to view the shared resources of the remote computer.Here “219.64.55.112″ is an IP address of remote computer that is to be hacked through Netbios.You have to substitute a vlaid IP address in it’s place.If succeeded a list of HARD-DISK DRIVES & PRINTERS are shown.If not an error message is displayed. So repeat the procedure 2 with a different IP address.



3. After succeeding, use the “net use” command in the command prompt.The “net use” is another netbios command which makes it possible to hack remote drives or printers.



Example-1:

C:\>net use D: \\219.64.55.112\F

Example-2:

C:\>net use G: \\219.64.55.112\SharedDocs

Example-3:

C:\>net use I: file://219.64.55.112/Myprint



NOTE: In Examples 1,2 & 3, D:,G: & I: are the Network Drive Names that are to be created on your computer to access remote computer’s hard-disk.



NOTE: GIVE DRIVE NAMES THAT ARE NOT USED BY ANY OTHER DRIVES INCLUDING HARD-DISK DRIVES,FLOPPY DRIVES AND ROM-DRIVES ON YOUR COMPUTER.THAT IS IF YOU HAVE C: & D: AS HARD DIRVES, A: AS FLOPPY DIVE AND E: AS CD-DRIVE, GIVE F: AS YOUR SHARED DRIVE IN THE COMMAND PROMPT



F:,”SharedDocs” are the names of remote computer’s hard-disk’s drives that you want to hack. “Myprint” is the name of remote computer’s printer.These are displayed after giving “net use” command. “219.64.55.112″ is the IP address of remote computer that you want to hack.



4. After succeeding your computer will give a message that “The command completed successfully“. Once you get the above message you are only one step away from hacking the computer.



Now open “My Computer” you will see a new “Hard-Disk drive”(Shared) with the specified name.You can open it and access remote computer’s Hard-Drive.You can copy files,music,folders etc. from victim’s hard-drive.You can delete/modify data on victim’s hard-drive only if WRITE-ACCESS is enabled on victim’s system.You can access files\folders quickly through “Command Prompt”.



NOTE: If Remote Computer’s Firewall Is Enabled Your Computer Will Not Succeed In Gaining Access To Remote Computer Through Netbios.That is Netbios Hacking Is Not Possible In This Situation.(An Error Message Is Displayed).So Repeat The Procedure 2,3 With Different IP Address.

Windows XP IP Utilities

The following are the IP utilities available in Windows that help in finding out the information about IP Hosts and domains.These are the basic IP Hacking Commands that everyone must know!




NOTE: The term Host used in this article can also be assumed as a Website for simple understanding purpose.



1. PING



PING is a simple application (command) used to determine whether a host is online and available.PING command sends one or more ICMP Echo messages to a specified host requesting a reply.The receiver (Target Host) responds to this ICMP Echo message and returns it back to the sender.This confirms that the Host is online and available.Otherwise the host is said to be unavailable.



Syntax:

C:>ping gohacking.com



2. TELNET

Telnet command is used to connect to a desired host on a specified port number.For example

Syntax:

C:>telnet yahoo.com 25

C:>telnet yahoo.com



NOTE: The default port number is 23.When the port number is not specified the default number is assumed.

Telnet Hacking is explained in detail in the following post.

How To Send Fake Email



3. NSLOOKUP

Many times we think about finding out the IP address of a given site.Say for example google.com,yahoo.com,microsoft.com etc.But how to do this? For this there are some websites that can be used to find out the IP address of a given site.But in Windows we have an inbuilt tool to do this job for us.It is nslookup.Yes this tool can be used for resolving a given domain name into it’s IP address (determine the IP of a given site name).Not only this it can also be used for reverse IP lookup.That is if the IP address is given it determines the corresponding domain name for that IP address.



Syntax:

C:>nslookup google.com



4. NETSTAT



The netstat command can be used to display the current TCP/IP network connections.For example the following netstat command displays all connections and their corresponding listening port numbers.



Eg: C:>netstat -a



This command can be used to determine the IP address/Host names of all the applications connected to your computer.If a hacker is connected to your system even the hacker’s IP is displayed.So the netstat command can be used to get an idea of all the active connections to a given system.
