  Cosmic ray (CR) upscattering of dark matter is considered as one of the most
straightforward mechanisms to accelerate ambient dark matter, making it
detectable at high threshold, large volume experiments. In this work, we
revisit CR upscattered dark matter signals at the IceCube detector, focusing on
lower energy data than was considered before. We consider both scattering with
electrons and nuclei. In the latter, we include both elastic and deep-inelastic
scattering computations. As concrete examples, we consider two benchmark
models; Fermion dark matter with vector and scalar mediators. We compare our
model projections with the most current constraints and show that the IceCube
detector can detect CR-boosted dark matter especially with masses below $\sim$
100 keV when scattering with electrons and $\sim$ MeV in the nucleon scattering
case.
