If you truly are white hat and return this, you'll not have only saved my family that includes a few month old baby, but you will go down in history as a legitimate hero and legend. If you do this, as an old hat myself, you'll have restored my faith in humanity and the true hacker spirit. God bless. Truly, if you keep your word, God smiles on you. I'll be contributing personally to a reward to you.
