We present bounds on dark matter (DM) in the MeV to GeV mass range, obtained by using X-ray measurements
from the INTEGRAL telescope. A crucial element, which allows us to derive bounds competitive or
stronger than existing ones from other techniques, resides in the inclusion of the contribution from inverse
Compton scattering on galactic radiation fields and on the CMB. This contribution is based on [1], to which
we refer for additional details.
