We propose a search for Higgs decays with as many as 8 leptons in the final state. This signal can arise in a simple model with a hidden vector (Ad) that gets mass via a hidden scalar (hd) vacuum expectation value. The 125 GeV Higgs boson can then decay H→hdhd→4Ad→8f, where f are standard model fermions. We recast current searches and show that a branching ratio (BR) of H→hdhd as large as 10% is allowed. We also describe a dedicated search that could place bounds on BR(H→hdhd) as low as 10-5 using only 36 fb-1 of data, with significant improvements coming from greater integrated luminosity.
