Go to here
https://support.steampowered.com/
And click on the options that's corresponding with your problem.
If you purchased software through Steam with a credit card, please confirm the card type (Visa, Mastercard, Discover, American Express), full name, expiration date, and last four digits of the card used with the order(s), all of that in your ticket that you will create for support.
If you give all of that info plus a CD-Key that's attached to your account of a game that you bought from lets say a Gamestop and then activated through steam, then you're definitely going to get your account back without a problem.
But it's your fault that you got hacked in the first place, don't download anymore illegal software/hacks, you more than likely have a key-logger.
Make a random password and write it down, change you Email Password, Steam password (When you get it back.), etc. all to that new password that you just made up and wrote down.
Good luck.
