How come Ramcharan's Yevadu song leaked ?

It is really bad to TFI.The full video songs are getting leaked before the movie release .This going to be huge loss to industry.We could see two video songs from Ramcharan movies got leaked and doing halchal in youtube.The producers need to take necessary action on the leakage.One song from Nayak(lila o Lila) and the other song(Gajuvaka) from Evadu was leaked .But We could see a water mark on the both videos as "THE HERO".Looks like both leakages was done by same person.
