Winter Challenges to warm the mind and heart.  
  Oh no! The Grinch is trying to steal xmas again! We need to know his plans so we can stop him, but they are password protected. We know all of his passwords start with "Gr33ngr!nch" followed by 3 digits. We found a salted md5 hash of his password "adbb281b13d6331dd694c6fafe2c8692:IhateSanta". Can you solve it?

@Croci bois (Rachel) know if you need a hint.
