Chaum et al. have very recently introduced cMix as the first
practical system that offers senders-receivers unlinkability at scale. cMix
is claimed by its authors to be secure unless all nodes collude (or less
than two senders are honest). We argue their assertion does not hold and
sustain our statement by three different types of attacks: tagging attack,
insider attack and passive attack. For each one, we discuss the settings
that make it feasible and possible countermeasures.
