I'm in real need for info about spywares??

[wael]

Hello everyone,

Can someone please explain to me how spywares work? I would like to know
how to capture all key strokes in any active application, also, getting the
contents of chat programs like Yahoo Messenger?

And before anyone is going to start flaming me, it is totally for my own
personal information and not for any evil purpose.


Thanks in advance.

You'll need a keyboard hook to capture these keystrokes system-wide:

Thanks for the reply.

Using keyboard hook will only log one side in case a user was chatting
online which is the machine where is the hook is installed, so, how do I get
both sides of the conversion, the local and remot???

Many spyware does that already, I am wondering how do they do it?!!


I appreciate the help.

If the control is a textbox (or based on a textbox or richtextbox), you can
use 'SendMessage' + 'WM_GETTEXT' to get the text. If this is not possible,
you may need sort of OCR software to analyze a screenshot of the control.

Just Google for some of the terms in my previous post, you should find tons
of information... Please understand that I don't provide code for someone
who uses "DaHacker" in his email address...
