  We have witnessed in the past decade the observation of a puzzling cosmic-ray
excess at energies larger than $10$ GeV. The AMS-02 data published this year
has new ingredients such as the bump around $300$ GeV followed by a drop at
$800$ GeV, as well as smaller error bars. Adopting the background used by the
AMS-02 collaboration in their analysis, one can conclude that previous
explanations to the new AMS-02 such as one component annihilating and decaying
dark matter as well as pulsars seem to fail at reproducing the data. Here, we
show that in the right-handed neutrino portal might reside the answer. We
discuss a decaying two-component dark matter scenario where the two-body decay
products are right-handed neutrinos that have their decay pattern governed by
the type I seesaw mechanism. This setup provides a very good fit to data, for
example, for a conservative approach including just statistical uncertainties
leads to $\chi^2/d.o.f \sim 2.3$ for $m_{DM_1}=2150$ GeV with $\tau_{1}=3.78
\times 10^{26}$ s and $m_{DM_2}=300$ with $\tau_{2}=5.0 \times 10^{27}$ s for
$M_N=10$ GeV, and, in an optimistic case, including systematic uncertainties,
we find $\chi^2/d.o.f \sim 1.12$, for $M_N = 10$ GeV, with $m_{DM_1}=2200$ GeV
with $\tau_{1}=3.8 \times 10^{26}$ s and $m_{DM_2}=323$ GeV with $\tau_{2}=1.68
\times 10^{27}$ s.
