  We present a supersymmetric formulation of Markov processes, represented by a
family of Langevin equations with multiplicative white-noise. The hidden
symmetry encodes equilibrium properties such as fluctuation-dissipation
relations. The formulation does not depend on the particular prescription to
define the Wiener integral. In this way, different equilibrium distributions,
reached at long times for each prescription, can be formally treated on the
same footing.
