  Official Ruling
  A creature with disturb is one that has the disturb keyword ability in its text box. Notably, permanents that were cast using the disturb ability rarely end up having disturb on the battlefield. Barring some very weird circumstances with copy effects, if a card's front face has disturb but its back face is on the battlefield, that permanent doesn't have disturb.
