My sister loves screwing around with my computer, and I've had to format it twice already, so I don't want her downloading random crap, etc anymore.

Anyways, I was thinking about placing a keylogger to terminate windows whenever she types in "Facebook" or "Ctrl+Alt+Del".

Google wasn't much of help. Anyone know how to make a keylogger?

Password protect the user account instead? Or give her a non-admin account and block certain sites and such.

It's always been my understanding that keyloggers just log keystrokes.

Passwords are annoying

You can detect when a password or key phrase is typed.

Haha, I doubt you'll be able to find a keylogger that can do all that, if you know C++ it's actually pretty simple to make your own, however, I would just get some administrative tools, like the ones they use at schools to disable task manager and block certain sites.

Create a Visual C++ program that starts up as minimized (or in the toolbar). Make the program record the keystrokes (look this part up, I think its aSync or something, I haven't used this in a while). Attach the program to a start-up .bin file.

1) Open HOSTS
2) Reroute the URLs to 127.0.0.1
4) ???
3) Profit

Teach Me.

Sorry, I don't condone the potential creation of viruses and trojans. Learn yourself.

Link me?

Just give her a non-admin account and password yours and you can probably let her do whatever she wants on hers. To install anything that affects the system, she will need to get your permission/approval for it. In case you ever leave your account opened up on the screen, make it clear that you want her to only use hers and why. Show her how to get to her account when your account is active, if needed.

This is none of the above, fuck it, cut the cord. Light out, Guerilla radio. Turn that shit up.

But seriously, this is not a ROM, mp3, hack, crack, ware, CDkey, or a virus. It has the POTENTIAL to be a virus, hence why I won't teach it to him.

Partition the hard drive and give your sister a small chunk. 20GB should be enough - a good iPod has about this much space.

Anyway, the point of partitioning is to completely isolate crap to her side. If you need an OS, get the Windows 7 beta or any UNIX based OS.

Getting keystates isn't really at all a trojan, virus, or whatever... It is used in games and all sorts of things. All you do is read the keyboard. Also fuck MSVC++. gcc, ftw.

In C++ just make a blank program, it's an option when making it, rather than making a console program, this will make it run in the background, no icon, nothing.

The function you'll want is GetKeyState to find which keys she's pressing, then you just either A: Monitor her keyboard and do actions based on keystrokes, or B: Record it all to a file.

The command I'm refering to is a lot easier and more reliable to use than GetKeyState().

Well, for the entire computer that's the only one I know that does it, obviously in the program things like getchar might work better, and why not tell him? If people want a keylogger they'll easily find one, and it sounds like this is being put to good use.

GetKeyState() -- returns the state of the Shift, Ctrl, and Alt keys for the current message, not the current state of those keys on the keyboard.

wParam holds the key that is down. Example:



GetAsyncKeyState -- returns the value of VK_* stuff.



Use:


Other codes:

WM_KEYDOWN -- virtual key code
WM_KEYUP -- virtual key code
WM_CHAR -- character code


I recommend using GetAsyncKey. It returns any VK_* value (which is pretty much anything on your keyboard) and its easy to initialize and so on.

If she will just agree to use a different user account, there is no need for all that work.
