I will review the current status of models of TeV dark matter transforming under a hidden sector nonabelian gauge interaction, with respect to explaining anomalous leptonic signals from the galaxy seen by the PAMELA, Fermi and INTEGRAL experiments. Special emphasis is given to the excess 511 keV gamma rays observed by INTEGRAL, and how the dark matter interpretation is constrained by Fermi observations of high energy galactic gamma rays. I will discuss the sensitivity of these results to the poorly constrained dark matter profile in the galactic central region.
