Ability: Cacophony (Really?)
Moves: Boomburst, Rest, Sleep Talk, Disarming Voice.
IVs: 6 In every IV.
I don't know, it looks VERY suspicious to me. Especially with the ability.
Cacophony is an unreleased version of the ability Soundproof. Because of the ability's name, yes, it is hacked. You are unable to change an ability's name through legitimate means. However, it is not OP because Cacophony is just a re-named Soundproof.
