Yes. Since the creature is not targeted, but is being affected by a global property neither hexproof nor shroud offer any protection.
702.17a Shroud is a static ability. “Shroud” means “This permanent or player can’t be the target of spells or abilities.”
702.11b “Hexproof” on a permanent means “This permanent can’t be the target of spells or abilities your opponents control.”
In both cases "not being targeted" is the key.
