  The 79-string IceCube search for dark matter in the Sun public data is used
to test Secluded Dark Matter models. No significant excess over background is
observed and constraints on the parameters of the models are derived. Moreover,
the search is also used to constrain the dark photon model in the region of the
parameter space with dark photon masses between 0.22 and $\sim$ 1 GeV and a
kinetic mixing parameter $\varepsilon \sim 10^{-9}$, which remains
unconstrained. These are the first constraints of dark photons from neutrino
telescopes. It is expected that neutrino telescopes will be efficient tools to
test dark photons by means of different searches in the Sun, Earth and Galactic
Center, which could complement constraints from direct detection, accelerators,
astrophysics and indirect detection with other messengers, such as gamma rays
or antiparticles.
