The nature of dark matter (DM) is still an open question for modern physics. In the particle DM paradigm, this elusive kind of matter cannot be made of any of the known particles of the Standard Model (SM). Many efforts have been made in order to model the nature of the DM. Among others, and beyond the SM of particle physics, we focus on brane world theory as a prospective framework for DM candidates. Branons are new degrees of freedom that appear in flexible brane-world models corresponding to brane fluctuations. They are a natural DM candidate, because branons behave as weakly interacting massive particles (WIMPs), that are one of the most favored candidates for DM. The ground-based gamma-ray telescope MAGIC could potentially detect DM indirectly, by observing secondary products of its annihilation into SM particles. In this contribution, we set constraints on branon DM from already published observations of dwarf spheroidal galaxies with the MAGIC Telescopes, by using a full likelihood analysis.
