Rare B decays of the type b → s~ℓ+ℓ-(νν) are analyzed in a generic scenario where New Physics effects enter predominantly via Z penguin contributions. We show that this possibility is both phenomenologically allowed and well motivated on theoretical grounds. The important role played in this context by the lepton forward-backward asymmetry in B→ K^*ℓ+ℓ- is emphasized.
