We present some results about the search for extragalactic sources located behind the Milky Way, based on near-IR data provided by VISTA Variables in the Vía Láctea Survey. We applied an algorithm that combines morphological and photometric parameters for the detection of extended sources of extragalactic nature in four regions at lower Galactic extinction. We have detected hundreds of galaxies never seen before, clusters of galaxies and the trace of a major structure in the direction of Norma Cluster. The good results so far obtained, will allow us to extend our search for extragalactic objects in the Galactic disk of the VVV survey, and its extension, VVVx.
