The cubic-kilometer sized IceCube neutrino observatory, constructed in the glacial ice at the SouthPole, offers new opportunities for neutrino physics with its in-fill array “DeepCore”. In particular, the use of the outer layers of the IceCube detector as a veto allows low-energy neutrino searches to be performed in the southern sky. This makes the Galactic Center, an important target in searches for self-annihilating dark matter, reachable for IceCube. In this contribution we present the results of the first Galactic Center analysis using more than 10 months of data taken with the 79-string configuration of IceCube-DeepCore, with a special focus on low WIMP masses reaching a sensitivity as low as 30 GeV. We also present the status of an analysis extending the sensitivity to WIMP masses up to the TeV scale.
