What's with all the judging... without really spoonfeeding, iTpHo3NiX is correct - there are many things you can do, sniffing traffic with Cain&Abel (windows) or Ettercap (linux) works good if you just want facebook sessions.
As for "hacking in", well that's a bit harder - you need to find open services and go through them, but this doesn't usually work for home computers. You could however perform MITM and redirect traffic to your own proxy which would feed her with malware downloads/driveby.

Thank you, much appreciated. I just wanted to know what my options were really.

As for motives asked by others , I want to do it for the challange. I dont want to steal anything or cause harm. If I stumble across something interesting that will be a bonus, but certainly not why im doing it.

Thanks guys.

Hello everyone,

This is my first post. I want to know how to access a PC/laptop that's already on my network, I have already tried Armitage with no luck. I was thinking there must be a different way.

I have some basic knowledge on networks etc. but I'm a relative beginner when it comes to hacking.

Thanks
