Sub-GeV Dark Matter particles upscattered by cosmic rays gain enough kinetic energy to pass the thresholds of large volume detectors on Earth. I will show how public Super-Kamiokande and MiniBooNE data already exclude previously allowed regions of both DM-electron and DM-nucleon interactions. I will then discuss search strategies and prospects at existing and planned neutrino facilities, such as Hyper-K, DUNE, IceCube and KM3NeT.
