Let me first introduce myself, since I'm new to this forum.
My real name is Robin, I'm a 25 year old male and live in the Netherlands (so already excuse me if I'm hard to understand:P)

I'm currently helping my friend, which is working on a textbased game. He asked me to find any ways trying to steal users' passwords, through sessionID's and whatever more is available.

Which possibilities are there to actually 'steal' someones password?
If you need any more information, I'd be pleased to give it to you.

All the best,
