We present a hidden Abelian extension of the Standard Model including acomplex scalar as a dark matter candidate and a light scalar acting as a longrange force carrier between dark matter particles. The Sommerfeld enhancedannihilation cross-section of the dark matter explains the observed cosmic rayexcesses. The light scalar field also gives rise to potentially largecross-sections of dark matter on nucleon, therefore providing an interestingway to probe this model simultaneously at direct and indirect dark mattersearch experiments. We constrain the parameter-space of the model by takinginto account CDMS-II exclusion limit as well as PAMELA and FermiLAT data.
