The other ICE peer, the STUN server, the TURN server (if any), and the
signaling channel are all under the control of the attacker in a worst
case scenario (the user being directed to a hostile or hijacked site). The
attacker essentially has perfect knowledge; the only thing we can add that
the attacker doesn't know is a random number with each packet.
