it doesn't steal your password, it relies on you to enter it. if you're dumb enough to enter it , it probably logs in with your msn ID to the chat servers and spams your contacts.. since msn ids = hotmail/msn addresses, there's lots of reasons for them to grab it. they could be spamming, they could be harvesting contact emails to spam, or they could be looking for all kinds of infoz.
