Can Eve control PerkinElmer actively-quenched single-photon detector?

Abstract: We show how PerkinElmer SPCM-AQR detector module can
be controlled by an eavesdropper using bright optical pulses, by
exploiting an obscure flaw in the detector electrical circuit. First
experimental results are reported. This loophole may make possible an
attack against quantum cryptosystems that use these detectors.
