How to hack a Steam account in simple and easy steps.
Step 1) Find the email of the users steam account, usually done by you tricking him into giving you his email, or you can ask someone he knows for it.
Step 2) Once the user's email is found, try to guess his security questions or passwords before attempting anything else, if they fails read step 3.
Step 3) Attempt to SE the email's provider, so if the user is signed up via yahoo/hotmail/live/aol/gmail email that company. So i will use yahoo as an example here. You will email them saying that you would like to recover a old email account and that you forgot all or lots of details pertaining to the account, say that it's almost a year old and you used to use it for important materials/products which you now need the need for, they may or may not link you to a recovery link so you can reset the password for that account. See step 4 if that fails.
Step 4) If all of the above steps fails, read this carefully, most likely since you are asking this you probably won't know a damn thing about "real" hacking, so i will try to explain this difficult and advance hacking technique. Okay, every website has a database, and a database is were the website stores information, like updates, posts, and sometimes even user's information on them. But, not all websites are vunerable to such type of brute force attack in an attempt to grab the databases so you will have to go a bit deeper than that. But, i can't go in any more detail cause i got be in some serious trouble but lets just say yahoo does have a vunerablilty within the news section of there site...
