  In the past years the spotlight of the search for dark matter particles
widened to the low mass region, both from theoretical and experimental side. We
discuss results from data obtained in 2013 with a single detector TUM40. This
detector is equipped with a new upgraded holding scheme to efficiently veto
backgrounds induced by surface alpha decays. This veto, the low threshold of
0.6keV and an unprecedented background level for CaWO$_4$ target crystals
render TUM40 the detector with the best overall performance of CRESST-II phase
2 (July 2013 - August 2015). A low-threshold analysis allowed to investigate
light dark matter particles (<3GeV/c$^2$), previously not accessible for other
direct detection experiments.
