Honestly the leaf village really does have really bad security. Time and time again we see villains easily slip through security with some even simply walking in through the front gates. It's not just at the village level either. Even clans like the Hyuga and Uchiha have had really lax security. Itachi and Obito seemed to easily wipe out the Uchiha clan with minimal resistance even from the most elite clan members. So I wouldn't really be surprised if people could just waltz into the Hyuga compound at night undetected. Security in the village really is almost non existent to the point that their security efforts could probably be spent elsewhere with better results.
