Several hints of the presence of a new state at about 95 GeV have been observed recently. The CMS and ATLAS collaborations have reported excesses in the diphoton channel at about this diphoton invariant mass with local statistical significances of 2.9 σ and 1.7 σ, respectively. Furthermore, a 2 σ excess in the bb final state was also observed at LEP, again pointing at a similar mass value. We interpret these intriguing hints of new physics in a variant of the Scotogenic model, an economical scenario that induces Majorana neutrino masses at the loop level and includes a viable dark matter candidate. We show that our model can naturally explain the 95 GeV excesses while respecting all experimental constraints and discuss other phenomenological predictions of our scenario.
