We have a department for that

I just had a thought, since it seems Book 7 will be at least in part a
quest for lost Horcruxes, that it really wouldn't do for "The Chosen
One" to run around asking suspicious questions and looking for very
specific objects. It's bound to raise eyebrows in the Wizarding
community, not to mention in the DE circle. Even Voldemort wouldn't
need more than ten seconds to figure out what's Harry is looking for.
It thus appears that we are in desperate need of a convincing cover
for a Horcrux hunt.

How convenient it is, then, that a new office was recently established
in the Ministry of Magic. This one is called the Office for the
Detection and Confiscation of Counterfeit Defensive Spells and
Protective Objects. Sounds like just the thing, isn't it? This office,
while conveniently a side one and far from the center of attention,
employs no less than ten workers, who spend long hours (frequently
until after midnight) searching and confiscating cursed Sneakoscops,
fake potions, Metamorph-medals and that sort of knick-knack. They were
even known to raid a DE's house merely on the ground of some
undisclosed "confidential tip-off". It probably wouldn't raise a
single eyebrow if they were after some magic lockets or cups. How
lucky, then, that Harry is in very good terms with the head of this
office (who is, in case you haven't caught up yet, one Arthur
Weasley). I wonder if 17 years old wizards can get a temporary job in
the Ministry while school is closed down for the war?
